If your tooth is dead, it will gradually darken, eventually looking like you probably imagine a dead tooth would look. If you are concerned about the health of your tooth, however, you should visit your dentist to discuss how it could be strengthened and protected or to see if an extraction would be best. A chipped tooth will not necessarily lead to infection and, minus infection, a root canal should not be necessary. However, it is best to have chips covered – with bonding, veneers, or a crown depending on location and function – to reduce your risks of infection and decay. Unless you are experiencing symptoms of tooth infection such as increased sensitivity to heat and cold, swelling or tenderness in the gums, or abscess, it is unlikely that you need a root canal. But, just like determining if your tooth is dead, it is always a good idea to bring oral health concerns to the attention of a trusted dentist.
