If you have a cracked tooth as a result of a very recent trauma or accident, contact your dentist immediately!
When a tooth is cracked, a filling may not seal the crack. A crown may have to be placed over the tooth to hold it and the crack together. If the crack is not restored, the tooth will become sensitive to chewing pressure, or will eventually break. It is important to restore a cracked tooth before it breaks, because in some cases a broken tooth cannot be crowned and must be extracted.
