You're saving money at both ends! Not only are you not buying X-rays, but it's also fairly likely that by the time a condition is serious enough to cause you pain, the only option left will be to pull the tooth. Extractions are definitely cheaper than fancy procedures like root canals, fillings, and crowns. At some point you might have no teeth remaining, and you won't have to worry about the issue at all!
Modern dental x-rays involve minuscule radiation levels.

before you spout nonsense.
Note: if a dentist or hygienist notices something, it doesn't matter if you had FMX or pano 3 months ago. Getting another BW or PA can make the difference between a tiny filling and lots of discomfort.
If you have a tooth with only 2 roots and one of them cracks, then it's better to just remove the tooth. Besides chronic infection that can hemorrhage, it will have to be extracted within 5 years anyway.
With 3 roots and only one cracked, sometimes dental surgeons can do something.
Also, the comment about dental x-rays being a profit center are clearly true. In SV, it's like they put you on a calendar for them, and they're usually done before an exam.
