Are cavities permanent?

Once the physical structure of the enamel is gone, it won't just grow back on its own like muscle tissue does after workouts. You have to get a professional filling. Keeping up a low-sugar diet definitely helps stop new ones from forming though.

Yes, once the enamel is damaged, you need a dentist to fix it. Just get a quick filling done to stop the decay from spreading further.

I kept reading articles online hoping mine would naturally heal, but it just made me more anxious. The damage to the tooth structure is permanent and cannot reverse itself. Please see a doctor soon so you can have peace of mind.

I tried oil pulling and salt water rinses for months, hoping to reverse my cavity, but it didn't work. Those methods are good for gums but they won't fill a hole in the tooth. Save your time and let a dentist fill it up properly.

Unfortunately yes, they don't magically repair themselves while you sleep, otherwise I would have perfect teeth by now. Once there is a hole, you have to get it plugged by a dentist. There is no shortcut here.

Hey, don't stress too much about it! Yes, the physical cavity won't disappear on its own, but a simple dental filling makes it a non-issue in just one visit. Just get it done this weekend and relax!
