Large Tooth cavity with no pain. Tooth.

Hello You need to go for rct post n core and crown

The amount of tooth structure lost is huge. After removal of decay and some vitality test it can be decided whether to do RCT (Root Canal Treatment) or no. After necessary tooth filling procedure is done the best treatment will be to get a Cap over this tooth.

Visit a dentist before the tooth becomes unsalvageable.

Do not wait for such decay to happen with other teeth. If reported early less expensive and less extensive treatment approach can be advised. Absence of pain can be explained by chronic / slowly progressing nature of decay.

From your photograph I'm able to visualize that you have a very deep tooth decay on your upper tooth. The walls of the tooth is fractured because of the infection and it appears as a dead tooth. That is the reason you are not getting pain. But do not leave it like that. Already 15 yrs of not attending the tooth is itself not correct. The disease is internal to the tooth and it is at the level of the root. You are lucky enough it didn't flare up all these years. Please remember this will not only affect the Mouth but the infection will be spreading to other parts of the body and its sub clinical. In our Centre at chennai we take up such challenges and do not remove the tooth. We try to save it by doing Root Canal Treatment and capping.
