question: Hi sir, i noticed a small hole in my gum on the right side of my jaw i do not have pain but when i consume cold or hot food it jitters.I am 21 year old i went to the dentist yesterday he just looked at the cavity for just 2 seconds not more than that. He said i have to under go a root canal treatment so i have to visit him 4 to 5 sessions and each visit will cost me Rs.600.He also suggested me to have a white cap or a metal cap.Please let me know is it a serious problem because i do not have pus or pain.I just wanted to know that is root canal ok for me at this age and i am very upset because many whom i know told that the root canal treatment will last only 3 years and i have to undergo the same treatment every 3 years. Any alternative please -- something that can solve the problem without root canaling let me know..
