Dental work (a few questions)

Hey there, I was wondering if ozone therapy can actually fix a tooth entirely. Say you have a tooth that’s mostly intact, but there’s a really deep cavity in there... Could you just go back for another round with a higher concentration of ozone if the first attempt doesn't quite cut it?

It’s been a long time since I sat in a dentist's chair—honestly, it's been ages—and I’m thinking about switching clinics anyway. I want to find a place that uses more modern, less "brutal" equipment... you know, something designed to actually save the tooth instead of just tearing it apart. I'd love to keep the tooth whole if possible.
I saw a dentist way back when—this lady named Sarah Miller—and she used to charge me roughly $100 for these ozone treatments. What's the deal with that nowadays? Is this something covered by my insurance, or am I looking at paying full price out of pocket?

Any advice is welcome, assuming it's coming from a good place. In your opinion, what’s the most effective way to handle this? I’m really trying to avoid the whole thing where they drill away the entire tooth until there's nothing left but a hollow shell... yeah...

If there's an actual cavity, ozone isn't going to fix it. The hole is already there because bacteria have eaten through the dentin. The whole point is to be minimally invasive—basically, don't drill more than absolutely necessary. With modern white fillings and a skilled dentist, that shouldn't be an issue at all. 😉
Besides, Medicare doesn't cover ozone treatments.

This is the actual thread, so please continue the discussion over there...
