All of sudden I felt my tooth was shaking and I rushed to my dentist. He told that it was not entire tooth that was shaking but half of the tooth was shaking. as there was a crack. He told the root of the tooth was fine but only lower portion was bad. He said that I have to get the entire tooth removed and there.was no other option. So I went ahead snd got it removed. Later when I searched the Internet, I found there were ways to save such tooth. I am feeling so bad that I lost one more tooth because of my dentists lack of latest knowledge. I want to confirm if my dentist did the right thing in order to decide if I should continue with him or find another dentist. Till now I have lost 6 tooth in all and have had 4 root canal. Could this be because my dentist hasn't been giving me right advice. I take care of my oral hygiene. I brush twice daily and rinse my mouth well after every meal and avoid eating sweet stuff but still my oral condition is in bad shape. Wondering if my doctor could have saved my oral condition by giving me timely advice by attacking the root cause rather than solving the issue as and when they were rise up?
