I have a cavity in my back tooth! What should I do?

Depending on your situation, filling alone may not be enough. If the dental pulp is inflamed, root canal treatment is needed to eliminate the inflammation. It costs about a hundred dollars, and the anesthesia is not very painful. The steps include pulp opening, root canal preparation, disinfection, and filling. When you find a hole, although it doesn't hurt, you should treat it immediately. Just patch it up and it won't hurt. Now that the inflammation has reached the pulp of the tooth, hurry up and treat it, otherwise the root tip will also become infected. It will not heal on its own without treatment. Wish you good health!
