If you don't get in the sun your teeth are going to fall apart. Dentin can be regenerated

Dr. Jack Kruse: "We're all taught that dental decay is a function of carbohydrates. That's a half truth. The real truth is if you don't get in the sun, your teeth are going to fall apart. The thing is, when's the last time any dentist ever told a parent the real reason your kid's teeth are falling apart? Yeah, putting the bottle in their mouth is a bad thing, but why is your kids vitamin D level nine?

"And you know what you'll be amazed to find if you're a dentist? Go and look at all these new dentitions that don't have anything but sealants in it, and then check their vitamin D level. You might be shocked to find out that people that have the best teeth have also the highest levels of vitamin D. What does it tell you? Remember, your teeth are basically neuroectodermal-derived things. Vitamin D controls the neuroectoderm.

"So does vitamin A. Vitamin A is the blue light part of the story, and vitamin D is the UV violet part. How about you get people out? Dentin really responds to the near infrared and red. That's the reason why those red lasers show that dentin can be regenerated.

"Well, if you got into a pulp chamber, don't you think it would be nice to have a special red laser light there instead of using Ketac cement, or whatever the hell you guys do now, or send it to the endodontist to pull the nerve out. I mean, what does Becker say about pulling the nerve out? You got no DC electric current in the tooth. Is that, you got any chance for regeneration?

Doug Sandquist: "No."

Dr. Jack Kruse: "What does that do to trigeminal signaling, you know, in the mandibular division? We don't know, but I guarantee it's UPEs."
