I have been going to the dentist and getting my regular every three months cleaning. At first, i was asked by my dentist to remove my wisdom teeth to which i refused. Recently, i started feeling some pain when two of my wisdom teeth would come in contact with either cold or hot food or water. My first question is is it possible to get cavities when i am getting my regular cleaning every three months? The next question is it necessary to have my wisdom teeth removed? In addition, i have been asked on many dental visits to different dental doctors to have gum surgeries which i had done before. I was told that i have "pockets" that necessitate me having the gum surgeries. My gums are not bleeding but according to my doctor i have bone loss. when is it necessary to have gum surgeries. I would appreciate it if you would answer those three questions for me. Thank you.
