If you ignore a cavity long enough, the tooth will require a full root canal. This can cause the tooth to become weakened over time. In order to essentially protect the tooth and get rid of the underlying decay, we recommend having a filling placed. Fillings are simple restorations that can be matched to the color of your existing smile.
In many cases, you won't know you have a cavity until you come in for an exam. During the exam, we use a special instrument to look for dark areas or soft spots in a tooth. X-rays further help us in identifying these trouble areas. If you have a cavity, it's recommended that it be filled sooner rather than later.
