When trying to find the cause of a toothache, you may need professional help. If the problem is not on the surface or not in the front of your mouth, your dentist will be able to help you diagnose the issue. Toothaches tend to be caused by one of the following:

Damaged Fillings

Even with regular home care, fillings will eventually need to be replaced. Depending on the material, your filling can last up to 20 years before failing. If your filling has fallen out, your dentist may decide to replace it or offer another solution if the damage is severe.

Broken Teeth

Teeth can be broken a number of ways, including biting down on hard foods, falls, and high-impact sports. Minimize the number of hard foods you include in your diet and wear a mouth guard if you engage in high-impact activities.

Decay

About 90% of adults in the United States have had a cavity. The best way to avoid cavities is with regular dental visits and good hygiene at home, brushing twice a day and flossing at least daily.

Abscessed Teeth

Cavities or cracks in your teeth may lead to a bacterial infection called an abscess if left untreated for too long. This infection can affect more than your mouth if it spreads, potentially causing fever and swelling of the face and lymph nodes, so it is important that it be treated promptly.
