When you come in for your routine exams and we find that there is a cavity in your tooth, it would be best to fix it as soon as possible. It may not be sensitive or painful, but if left untreated, it has a possibility to get bigger. If that happens, there is potential that further, more invasive treatment will be necessary.
Sometimes when a tooth breaks or decay has reached the nerve and blood supply in the middle of the tooth, the nerve becomes irritated and inflamed. When inflammation is present, so is infection, which is usually when you start to feel pain or soreness. However, soreness/pain is not always present when a root canal is diagnosed, but the infection still needs to be treated.
Crowns & Bridges
If a cavity is too large or a fractured or broken portion of the tooth is too large to just place a filling, a crown may be recommended. We also almost always place a crown after a root canal. Crowns can also be used to alter the appearance of your teeth: for example, make the tooth appear more straight or close spaces between teeth.
Bridges are recommended when there is a space between teeth that needs to be filled. One alternative to a bridge is an implant. (see extractions and replacement)
