How bad does a tooth have to get before it can be saved by root canal treatment?
i don’t know if this helps but a couple of years ago i had the most terrific pain in my tooth it had a huge hole in the back molar and i had lost half the tooth i thought it would have to be taken out but the dentist said no i needed root canal treatment they cleaned the tooth out and packed it with a gauze then i had to come back and have it filled with a root canal filling by that time more of the tooth was coming away but my dentist said the tooth could be saved i have had it refilled twice now and i would say there is more filling than tooth but my dentist said even the most rotten tooth can be saved if the nerve is causing the problem because its the nerve that causes the pain and if its a permanent tooth they would rather save it than take it out good luck
