A toothache or tooth pain is caused when the nerve in the 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 by 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 for children's teeth.
John Gamba was 9 years old when a dentist failed to anesthetize a back molar properly and hit a nerve dead-on. The result was a lifelong fear of dentists that reached a peak in his 20s, when he stopped going to the dentist entirely. "I couldn't even drive by a dentist's office without getting stressed out," he tells WebMD.
Gamba was 38 when a chipped back molar began to decay, eventually causing him constant pain. "I was paralyzed. I couldn't even consider going [to the dentist's office]," says...
Toothache occurs from inflammation of the central portion of the tooth called pulp. The pulp contains nerve endings that are very sensitive to pain. Inflammation to the pulp or pulpitis may be caused by dental cavities, trauma, and infection. Referred pain from the jaw may cause you to have symptoms of a toothache.
Toothache and jaw pain are common complaints. There may be severe pain to pressure, or to hot or cold stimuli. The pain may persist for longer than 15 seconds after the stimulus is removed. As the area of inflammation increases, the pain becomes more severe. It may radiate to the cheek, the ear, or the jaw. Other signs and symptoms that may lead you to seek care include the following:
Pain with chewing
Hot or cold sensitivity
Bleeding or discharge from around a tooth or gums
Swelling around a tooth or swelling of your jaw
Injury or trauma to the area
These signs and symptoms may sometimes be associated with dental decay or gum disease (periodontal disease). Dental decay or an area of redness around the tooth's gum line may point to the source of pain. If you tap an infected tooth, it may make the pain more intense. This sign may point to the problem tooth even if the tooth appears normal.
A toothache needs to be differentiated from other sources of pain in the face. Sinusitis, ear or throat pain, or an injury to the temporomandibular joint (TMJ) that attaches the jaw to the skull may be confused with toothache. Pain from a deeper structure (called referred pain) may be passed along the nerve and be felt in the jaw or tooth. In order to pinpoint the source of the pain and get relief, call your dentist or doctor.
When to Seek Medical Care for a Toothache
You should call your doctor or dentist about a toothache when:
Pain is not relieved by over-the-counter drugs.
You experience severe pain after a tooth is pulled. This may occur on the second or third day after tooth extraction. This is a result of the tooth socket being exposed to air. The condition is known as "dry socket syndrome." If you develop this condition, you should see a dentist within 24 hours.
Pain is associated with swelling of the gums or face, or you have discharge around a tooth. Fever is an important sign of infection in dental disease. Simple dental decay (caries) does not cause fever. These signs may signify an infection surrounding the tooth, the gum, or the jaw bone (mandible). Fever and swelling may indicate the presence of an abscess. Dental abscesses may require antibiotics and surgical opening (drainage) of the abscess. When this procedure is recommended to be done inside the tooth (endodontic drainage), a "root canal" is performed.
Broken or knocked-out teeth occur from an injury. Unless associated with more severe injuries, your dentist should be contacted as soon as possible. Swallowed teeth and permanent tooth loss are considered dental emergencies. Tooth loss due to injury (traumatic loss) is cared for differently in children who have lost their primary teeth than in older children and adults with injury to their secondary -- or permanent --teeth.
Pain is present at the angle of your jaw. If every time you open your mouth widely you have pain, it is likely that the temporomandibular (TMJ) joint has been injured or inflamed. This can occur from an injury or just by trying to eat something that is too big. Your dentist may be able to suggest solutions to this problem.
Wisdom teeth are causing pain. As wisdom teeth (third molars) are coming out, they cause inflammation of the gum around the erupted crown. The gum overlying the crown may become infected. The tooth most commonly involved is the lower third molar. The pain may extend to the jaw and ear. There may be swelling in the affected area so that the jaw cannot be closed properly. In severe cases, pain in the throat and the floor of the mouth may make it difficult to swallow.

Only 18.5% of Americans never floss. You are missing out on a simple way to make a big difference in the health of your mouth. Regardless of how well you brush, plaque still forms between your teeth and along your gums. Floss removes food trapped between the teeth and removes the film of bacteria that forms there before it turns to plaque, which can cause inflamed gums (gingivitis), cavities, and tooth loss. Try flossing just one tooth to get started.
You are one of 31% of Americans who don't floss daily. You are missing out on a simple way to make a big difference in the health of your mouth. Regardless of how well you brush, plaque still forms between your teeth and along your gums. Toothbrush bristles alone cannot clean effectively between these tight spaces. Flossing removes up to 80% of the film that hardens to plaque, which can cause inflamed gums (gingivitis), cavities, and tooth loss. Aim for 3 more days!
