Boosting teeth’s healing ability by mobilizing stem cells in dental pulp

I get that much of it works, so there's not a lot of need to throw it out, but where's the progress? My eye doctor visits add new technology regularly. Not often, to be sure, but still regularly. My eye doctor visits now are quite a bit different in many ways than they were when I first got glasses.
There's a point where I started to wonder if dentists in general are worried about becoming obsolete. That's conspiracy theory, of course, so I don't take it seriously. But I do wonder all the same.
What?
Batteries have made enormous strides in the past two decades. Surely, you remember the days of almost everything running off AAs, which took hours to recharge (If they were even rechargable), and tended to leak their contents at the slightest provocation.
Or, alternatively, you could shell out large amounts of money for lithium-ion batteries, which wouldn't hold half a charge after ~50 cycles, and which would be at 1/6th their original capacity after ~100 cycles.
If anything, battery technology has been a monumental success story. No, we don't have batteries based on unicorn farts that charge in 20 seconds, and hold more energy then gasoline. But what we do have is pretty damn amazing.
I'd think the secondary experience is in laptop batteries, and I'd hazard a guess that there's a similar but less extreme story: perception is similar battery life (perhaps because most life extensions come from low-power modes, so anyone actually using their laptop doesn't reach the claimed numbers for modern laptops?).
Of course, a third major factor is that people tend not to notice incremental improvements as much as step changes, and tend not to "upgrade their battery" in a comparable way.
All told, in relative terms there's probably some truth to it; other technology has progressed faster. But I wholeheartedly agree things have got better.

There was a CT scan of my mouth, and then a bolt was selected and a ceramic tooth created that would accurately fill the gap. It works just like a real tooth, except it is slightly chunkier (but it's chunkier in the direction that points inside my mouth, so I'm the only person who can tell).
It felt pretty high-tech to me, although the article mentions that the first titanium dental implant was placed in 1965.
The best bet we have to replace that are root-analogue implants [1] - essentially a physical 3D-printed copy of the whole tooth, including roots. Unfortunately information is scarce (as you can see in that wikipedia page), it's not even mentioned in the main 'Dental implant' article. There is a single dentist in the entire world [2] actively offering these implants, and going at it for 20 years.
[1] https://en.wikipedia.org/wiki/Root_analogue_dental_implant
We tried very hard to get even one sentence into the Wikipedia article, to no avail. The editors insist on secondary sources of information (articles in magazines or newspapers), which apparently must be in English. Sadly, all news pieces so far have been in German.
We were equally unsuccessful in raising interest among popular science journalists.
Here's one paper I found while reading around about the technology (no idea what sort of credibility JOADMS has):
http://www.joadms.org/download/article/149/19102016_27/14762...
However, you also have to factor in the long-term cost: there are no surgical complications, and no follow-up treatments to deal with infection, as would typically be the case with typical screw-type implant. This is a huge win.
Also note: BioImplant is currently a single tooth replacement, so it's not possible to get a row of adjacent implants. (At least, not yet - I understand this is more an issue of research than practicability.) Make sure you go through the FAQ on the website! (http://www.bioimplant.at/faq-2/)
The founders are medical doctors, one a maxillofacial surgeon, the other a famous heart surgeon, both associated with the Medical University of Vienna.
Lastly - you'll have to take this on trust - I have a BioImplant. It's a front incisor (one of the worst places to get an implant). That video on the website front page - that's me! I've had it for about 5 years, and it's faultless.
1) What sort of guarantee does BioImplant offer?
2) If an implant fails can it be removed and replaced?
3) When do they expect FDA approval? Why haven't they received it after over a decade?
4) Why is it only a single tooth procedure? Have they never tried to replace a row of teeth?
5) Who are the primary customers to date (how many and where from)? If these are foreigners traveling for the procedure, why don't they offer details on how to go about scheduling the trip/travel and the procedure/stay?
2) The first few weeks are critical: if the implant fails (ie. falls out), the procedure can be attempted again. If it's a complete failure, no damage was done, and one can opt instead for a regular screw-type implant.
3) FDA approval: other zirconia implants are already approved. A few years back, we got quite far with the BioImplant application, but other (medically unrelated) issues intervened, which I can't really discuss here. However, I agree: it's a top priority.
4) It's currently only medically proven for single tooth replacement. Research and trials are needed for multiple teeth.
5) The patients come from all over the world, wealthy and otherwise. I don't know exact numbers; I seem to recall it's in the hundreds, but you should phone to be sure. The other details: schedule, procedure, are all sorted out by telephone or email. Usually an X-ray or CT scan is the first thing to send.
There are many implant companies, all vying for attention. It's difficult to fight through all the noise. The top academic journals are another barrier: their main concern appears to be to maintain the status quo.
Popular science journalists didn't express any interest when we approached them. I was very surprised by this!
Lastly - and probably most importantly - the company really needs to get a decent PR person on board!
I think the reason is that there are too many implant companies, so competition is fierce. The editors are rightly suspicious of product placement or promotion. However, where there is legitimate innovation in an otherwise stultified field, it's important to draw attention to new developments. Perhaps it's time to try again for an entry!
I'm curious because this sounds rather like an 'anatomic' implant; the world leader in this technology is this small (but awesome) company in Austria: http://bioimplant.at
Here's an X-Ray of the titanium bolt: https://img.jes.xxx/594
And here's a temporary plastic tooth that I had installed while the ceramic one was being manufactured: https://img.jes.xxx/741
The inner screw has a small torx head on it and is threaded up the inside of the larger bolt that is tapped directly into the bone of my jaw.
Nowadays they just shine a near-UV light on them for a couple seconds and it's done.
Are people still getting braces glued on is it going the way of the molded clear plastic things? They were the hot new item being advertised back when I was getting my teeth fixed.
Yeah, I'm not sure about braces now. I do hear ads for that invisalign product, or something close to that. So that's probably what's being used now.
Would've loved to do without the wires popping out and stabbing me in the mouth, it wasn't a favorite part of my childhood. So much orthodontia.
Would be great if you're doing it as an adult, I wonder how most kids would do with the "must wear 22 hours a day" part. If I could've taken my braces out I probably would have. OTOH I had a couple other removable mouth appliances and managed with those, so maybe it's just because braces are awful that I wanted to get rid of them.
My takeaway is that teeth are very stubborn and don't like to be moved quickly. And that once moved, they really want to go back to the way they were. There is a lot of new tech, but you've gotta find the right ortho. I shopped around until I found a forward-thinking one who was willing to try new things, and got spectacular results within a reasonable timeframe.
That's my belief too. I had my metal braces removed a year ago, I have to wear retainers overnight, and I'm still finding the retainers quite a tight fit when I first put them in, especially if it's later in the evening than normal. My orthodontist says this indicates there's still some movement of the teeth.
I checked out their site https://fastbraces.com/ but it looks like it caters to dentists. It's about 50% of the price at least that's comparing a quote from an orthodontist. I just don't know enough about it.
I have one of them for my retainer, which is quite a bit nicer than the plastic and wire retainers of old.
Of course, this was like 13 years ago, so I'm sure times have changed.
If they are, someone should hold their hands and reassure them, or something. I haven't been to a dentist in about 6 years, mostly due to procrastination - though I can afford to have work done, I don't have coverage for it.
I'd be a lot more enthusiastic about going if I thought they could actually fix something, instead of announcing that they want to drill more holes in my teeth every time.
If you have a lot of cavities to fill, I would advise knocking it all out outside the country. I went to a dentist in Medellin that did an amazing job, basic cosmetic and restorative work on my whole mouth plus the plane tickets and a 21 day stay in an AirBnB totaled out cheaper than my Atlanta dentist wanted for one inlay.
And there are a tonne of other things your dentist will be checking each time. Paying ~$100 a year is a small price to pay to keep your teeth healthy.
Probably you're not at that point, but please go and check.
Unfortunately, a surprising number of manufacturers don't take this into account when formulating ceramics for crowns.
It's quite disconcerting to find yourself in a night club, unable to smile or talk properly because of the huge black gap in your teeth...
Sounds like a cool way to embed secret messages on your teeth.

And the amusing inverse! https://m.imgur.com/gallery/lcmSI
I don't think it's a huge deal though. I have had my false tooth for nearly 5 years and never found out it looks different under UV until now.
So this is a classic disruptive technology, in a market where people pay out-of-pocket(if not in the US , in many other places). so why haven't this disrupted the old way?
He breaks out so much new tech when I visit my friends and family think I'm crazy for going to him. I refer to him as my mad scientist.
Sure, brushing and flossing helps, but to say it eliminates dental professionals is absurd. That's like saying a healthy lifestyle means you'll never need a doctor or visit a hospital.
I don't believe it, whatsoever. In fact I challenged some friends (a dentist, an orthopedic surgeon, and a biochemist -- all researchers affiliated with prestigious institutions) to provide that scientific evidence, and after a year they all concluded that standard dental advice is simply wishful thinking. Since it is the recommendation of dental associations, a practicing dentist must give this advice, but that doesn't make it true.
Dentistry has these things too. I think some whitening products are an example. Turns out you don't actually need to be a dentist (from a technical / clinical knowledge perspective) to sell these products, so a lot of random retailers started selling them for a lot cheaper. Dentists got mad, and in these situations the ADA or regional dental associations can drive legislative change. Not saying this always happens, and it certainly isn't unique to dentistry, but these economic issues often dictate what tech gets marketed and what doesnt. If the tech offers a real and meaningful clinical improvement however (whitening does not count) then the tech gets to the market eventually
The issue I see with this approach is that 1) the risk / benefit is not super great, and not better than standard of care from what I can tell. Fillings work pretty well, and if there is any risk you can get cancer or other bad things happen from this regenerative med, it wouldn't be responsible to prescribe it. Further, marketing this would require expensive clinical studies, and you'd never be able to charge enough to recoup this cost. Unless there is a significant clinical benefit, no insurance company would pay for an expensive med vs a simple filling.
This is why most drug developers using cutting edge tech target areas of significant unmet need, like late stage cancer. If it works, you really provide a ton of value to patients (extending health span and life), so insurers will pay you for that value. If you are offering a "cooler" alternative to something that pretty much works, not so much
Profit-driven without competition is the worst of both worlds.
These paperclips have the potential to infect healthy gum tissue with nasty anaerobic bacteria from pockets that are already infected. Unless you use one clip per pocket, of course.
If you want good measurements of disease progression, it's much better to use e.g. a BANA test that estimates pathogenic bacteria counts. Or if you are really fancy, sample some gum pockets and get a bit of 16S sequencing done with a MinION.
Translation only, I have no data here aside from that my hygienist does seem to use the same probe without doing much between teeth when my gums are measured this way.
http://www.rdhmag.com/articles/print/volume-24/issue-9/colum...
Bacteria already have a great chance to move around the mouth. Healthy pockets are healthy not because they haven't been exposed to bacteria, but because they are place bacteria can't get a foothold.
I believe the medical glow makes it appear more sophisticated than it appear, justifying the high costs.
It takes a certain type of personality to become a dentist.
im sure that everyone can do their own thinking on that subject.
but I have had the gamut oof good to bad dentist experiences;
good: father in law (who was a dentist) was a great man
bad: dentist accused me of having braces (I have perfect teeth - never had braces) -- then charged my insurance for a bunch of procedures which werent performed (I only had a cleaning)
https://www.forbes.com/sites/michelatindera/2017/04/25/out-o...
When they were literally crumbling away later in life, the dentist told me to wait before replacing them, as new filling materials coming down the pike.
So I did, and got all the old fillings drilled out and replaced with epoxy ones that match color with my teeth, will last the rest of my life, and hold the weakened tooth together.
I wish I'd had that paint available these days when I was a kid, that is painted on the tooth and prevents decay.
* the evolution of dental curing lights from cumbersome, active refrigerated, and wired into really light, portable, wireless flashlights/pens
* the introduction of sodium bicarbonate jets for cleaning, polishing and whitening teeth
* the introduction of the ultrasonic scaler
* the change from dental amalgam (mercury-based), for fillings, to cast resin or ceramic
* the introduction of whitening treatments
* the changes from really bulky braces to relativevly slim ones, transparent and low-profile brackets, new techniques that do away with external head-gear for a lot of cases
I've also heard of crowns being 3D imaged and milled from a ceramic blank while the anesthetic takes effect, but only from one person.
I've been looking into root-analogue implants [1] - essentially a physical 3D-printed copy of the whole tooth, including roots. Unfortunately information is scarce (as you can see in that wikipedia page), it's not even mentioned in the main 'Dental implant' article. No drilling required, the implant is literally pushed into place after removing the tooth [2].
There is a single dentist in the entire world actively offering these implants [3], and going at it for 20 years. The idea and results seem solid, you can find several papers from other researchers confirming that it works. Last year a company announced a similar root-analogue implant (though titanium instead of ceramic) in the Netherlands, but haven't seen anything since.
Current root canals are filled with 'gutta-percha', a natural latex used since the 1800s, quickly blacken and are a common source of complaints. I have a single filled tooth and it seems to collect way more plaque than its neighbors. It really feels like an ancient tribal practice rather than modern medicine.

Above age 35 or so, rather than direct dental caries, the bigger risk for many people is receding gums (gingival recession), which also leads to tooth decay, hot/cold sensitivity, tooth loss, infection, and so on. To try and prevent this, people go to their dentist for scaling and root planing ("conventional periodontal therapy"), which are fancy terms for what is, to me, medieval treatment -- scraping the teeth with metal instruments that readily damage the enamel and dentin. I believe Periogen is a far superior alternative, which is administered using a waterpik and is able to reach significantly below the gumline. Periogen dissolves dental calculus chemically, without the risk of damage that comes with the instruments used in conventional periodontal therapy.
Another treatment that promotes healthy gums and discourages tooth decay are probiotic lozenges; the exact formulation differs from brand to brand, but in general the idea is to replenish the microbial colonies in the mouth with species that are helpful rather than harmful.
As far as I can tell, the simplest and most effective preventative measure against cavities is to vigorously wash the mouth out with water after eating or drinking anything, every time, no exceptions.

Edit: I'd like to apologise. I was raised in a rural area without floride or proper dental care. My teeth are in a place where no matter what I do I will be losing almost all of them over the next decade. I am frustrated.
I think it was a video segment on The Daily Show, with Beth Littleford as the correspondent. So that would have been quite a long time ago, somewhere from 1996 to 2000.
Edit reply to your edit: I am sorry about your teeth. It is amazing how dental education still isn't pervasive -- she gets teenage patients in Oakland who've never been told to brush their teeth and who will lose them all at a young age. Modern dentistry can work some wonders, so long term I hope you are doomed only to some discomfort and costs and not more severe problems.
Thought that flouride worked topically?
Where I grew up people still put Dr. Pepper in baby bottles, and become grandfathers at 35. That sh*t doesn't just happen on TV.
Though, now that I think about it, it's only in the past 30 or so years that soft drinks have become so cheap that people drink it almost exclusively. When I was a little kid poor families could only afford to drink watered-downed Kool-Aid, if that. So the soft drinks->bad teeth thing is probably a recent development, which fits with the increase in diabetes, too. Not just soft drinks, but the affordability of high caloric foods, generally. But false teeth were still far more common than even today.
I empathise with your having to deal with dental problems... Everyone experiences it at some point and no one enjoys it. But I think this is the right strategy for science, perhaps it wont help us directly, but it will help our ancestors.
Read the book, "Kiss Your Dentist Goodbye".
Despite the clickbaity title (well, the paper book equivalent), it talks about how your teeth naturally do regenerate in the proper conditions, and what those conditions should be [1]. I've been personally using the system for a few years, and the last couple times I went to the doctor, no cavities have been found and my teeth are healthy.
1. If you want to skip the why and get to the how, you can read this web page and other links on it for more detail: https://drellie.com/my-system/ The only thing I do differently is include flossing using floss sticks.
Uh, no. Your enamel can't be replaced. However, your dentin is regenerated constantly, in the same way that bone is regenerated. People with really good genetics can even over-generate dentin. Not only have I read about this, I know this firsthand, because I have developed "spurs" on the corners of some teeth where the enamel has gotten chipped. Dentin isn't as hard as enamel, but it's still pretty darn hard. Plenty hard enough to chew with.
This your problem, they absolutely aren't. Please take care of your teeth, people.
I am in a similar boat. I first learned about flossing in my 20s. My mouth is now full of crowns and fillings and it's just a matter of time to get implants or something else.
Unfortunately dentistry doesn't have any "good" approaches. All of them are just various degrees of "bad".
But you can slow down the decay a lot. The best thing I have ever done was to get an oral irrigator. It has helped my gums a lot so my teeth are pretty stable now.
In case it makes you wonder how they can keep doing that they spend more money lobbying than any other industry. They are right up there with the NRA. Suprising but true

So I took a toothpick and cleaned out the gunk and washed it out with peroxide. (just on the toothpick) I kept it clean with a tooth pick, and intentionally swished spit around the tooth regularly.
Eventually the hole filled back in.
I know teeth can "heal", but I think "re-calcify" is a better term I ran into the past few years. But like anything else on your body, I think it hits a point where there's nothing you can do about it.
I knew a lady that drank so much coke that it ate her teeth away, nothing that lady could do about fixing her own teeth.
We've updated the title above to a representative phrase from the article body.
The downside is that they weren't allowed to sell the genetically modified version, they had to derive it from natural bacteria and formulate it to be a daily supplement instead of a permanent replacement.
Do the tablets work? Seems like they'd be a bigger deal.
There couldn't possibly be any perverse financial incentive to make you keep buying their product repeatedly instead of only once.
Considering how poor the sales of the tablet have been, I'm sure they'd rather be charging $20,000 per treatment. They actually sold the entire tablet business for $2m which is pretty abysmal compared to the value of 'curing tooth decay forever'

Edit: i see a lot of similar comments here. This hope market has become a plague
I even think I recall info coming out about results from a mouthwash developed by the Australian military that regenerated teeth.
I've been waiting ever since.
As somebody who has left dentists and hygienists completely quizzical about some of the mineral decay on my teeth (in spite of my praised hygiene habits), something like a periodical regenerative treatment or a regular mouthwash would make me so happy.
In the interim, I've been recommended and given a Japanese toothpaste that contains some extracts of dairy (cheese?). I can't remember for the life of me what it's called, but it's supposed to help with some of the enamel and mineral issues. If anybody knows off hand what it's called. I think it begins with an M...
Xerostomia is a bitch, and will lead to what hire describing. Xylitol gum and something like Xylimelts can help. I speak from personal experience.
Thanks for the pointers. I'll look into them.
Only habit change: I dropped net carbohydrates to 20g per day. I did that for a chronic condition, but the change in dental health was a pleasant side effect. My dentist told me he's never seen such a dramatic difference. Gum-inflammation was causing gaps between my teeth, and that receded to where he couldn't detect it any longer. I went from a teeth cleaning once every other month to once every four months, and that is only by personal choice to get what little buildup he can find (the cleanings are nearly perfunctory, about 10 minutes now). Yet my dental routine has worsened, as I no longer brush and floss after every meal (going to one meal a day at the end of the day also gave me time to brush and floss after that).
YMMV. I suspect a large genetic component, and dropping carbohydrates will impact dental health for some even with a modest drop to 1-200g net carbs per day, and not at all for others even down to 20g net carbohydrates.

I am quite conflicted about science news of this nature. "Study looks interesting!" covers 95% of these stories, but doesn't have the same jazz to it as the headlines we get.
To be honest, I've consumed thousands of these stories. Not a one of them provided information that I ever found valuable. They just took up a few minutes of reading and provided some fodder for online conversation.
