Tooth sensitivity is often dismissed as something minor, but sometimes it can be a sign of a cavity.
If a tooth suddenly reacts to cold drinks, sweet foods, or even air, it may mean the protective outer layer of the tooth has been affected. When this happens, the inner part of the tooth can become more sensitive to temperature and pressure.
While sensitivity can have several causes, a small area of decay is one possibility that should not be overlooked.
Having the tooth checked early can help identify the cause and prevent the problem from progressing further.
