1-Fasting won’t heal your cavities. Doesn’t matter if you fast for a day or a year, your teeth won’t recover from a cavity.
2-I had one wisdom tooth pulled while I was awake and it was the most terrifying experience of my life to include the time I nearly died and was in the hospital for 3 days.
3-you can always try to get the cavities filled instead of getting them taken out unless they cavities are really large or the tooth has developed a crack. I have had a cavity in my wisdom tooth filled no problem and it’s been just fine for years.
Just a personal experience, I was able to reverse an early cavity swishing coconut oil two or three times a week. It’s antibacterial. I didn’t think it would work. After not going to the dentist for 5 years (no money) I was scared my mouth would be a mess. The hygienist said there was nothing to do. I was shocked.
Can this work? I have 4 cavitys 1 in each wisdom tooth that I’ve had for a while. Last thing I want to do is go under for surgery. All thought I know it almost has a 100% success rate it scares me having my brain levels brought down akin to that of a dead person. if fasting won’t heal them, I’ll have to get them pulled awake.
