If you are having a toothache, it is important to get it treated as soon as possible. A toothache is a sign of an underlying problem with a tooth or multiple teeth.
If left untreated, dental problems may increase in severity over time. Treating the dental problem early will almost certainly be less costly and extensive than if the problem is left alone.
Ignoring a toothache will only make the problem worse. Even if the pain goes away, the dental problem that caused it still remains so it is important to have a dentist investigate the problem to prevent it from worsening.
