Can you tell me exactly what goes on in a root c?

In root c the dentist after taking an x-ray of the tooth drills a fine hole in the cavity until the nerve is exposed, and becomes dead. He then does the filling. The purpose of root c thus is to drill deep inside the tooth until the nerve is dead and mainly so that once the permanent filling is done with the dead nerve there is no cause for pain to arise. Coming to the other part of your question he would inject anaesthesia and the only painful aspect is the prick of the needle which is minor. I am sure dentists in Phillipines are good. If your tooth is loose and your molar is getting shorter, I am sure a good dentist would not go in for root c. Ask your doctor always, never hesitate of the pros and cons and consequences and all other details and keep a record with yourself so that you know what you got done and where, when and how. For all times it will come in handy and be of help. Wish you good luck.
