A toothache is the most common type of dental pain and, when severe, it is considered a dental emergency. However, any type of dental discomfort should not be ignored and should be addressed as soon as possible. A toothache of any degree is one of the most common reasons for emergency dental appointments. Diagnosing the cause of the discomfort can sometimes be challenging. Seeking the assistance of a dental professional is the best course of action in order to address the problem efficiently and with expertise. Treatment will depend on the exact cause of the discomfort and may involve repairing a cavity with a simple filling or as complex as a root canal procedure. If left untreated for too long you may have the only option of an extraction. The relief of dental discomfort is best diagnosed and treated by a professional dentist.
