Using the electric toothbrush and flossing before bed every night, I feel like in my morning my mouth actually still feels fine. Of course I would never start my day without brushing, but my mouth doesn’t feel icky when I wake up in the morning. Sorry if that’s TMI.
If you only brush once a day, brush last thing before bed.
If you brush before eating, there will still be some plaque left and once you eat there should be copious amounts of sugar and food for it to snack on and quickly multiply + produce acid.
Acidic foods temporarily weaken your enamel to the point that even light brushing can damage it.
If you brush immediately after eating, you’re partially brushing their enzyme shit into your teeth…
There are also some tricks for oral hygiene that you don't get traditionally or when you go to the store for toothpaste. You can try putting a drop of Dragon's Blood on the toothbrush or brush with a bit of ozonated oil to help gum issues.
You can find the oral irrigator/toothbrush combos for looking for faucet oral irrigator on amazon. Maybe I'd misremembered the shower ones that are harder to find for the combos of both, but they're easy enough to find for a faucet adapter.
