Toothache Overview

Toothache or tooth pain is caused when the nerve root of a tooth is irritated. Dental (tooth) infection, decay, injury, or loss of a tooth are the most common causes of dental pain. Pain may also occur after an extraction (tooth is pulled out). Pain sometimes originates from other areas and radiates to the jaw, thus appearing to be tooth pain. The most common areas include the jaw joint (temporomandibular joint or TMJ), ear pain, and even occasional heart problems.

Bacteria growing inside your mouth can contribute to gum disease, plaque, and dental decay. These problems can become painful. The cause and prevention of dental disease has been well investigated.

You can prevent the majority of dental problems through flossing, brushing with fluoride toothpaste, and having your teeth professionally cleaned twice a year. The dentist may apply sealants and fluoride, which are especially important in children.
