What can cause a toothache?

You can develop a toothache for many reasons, but the most common cause is tooth decay. When a tooth's structure breaks down, nerves may become exposed. If the nerves are irritated, your tooth will throb. Other causes of toothaches include:
  • infections
  • gum disease
  • trauma, such as a blow to the mouth
  • teeth grinding
Make an appointment to see your dentist right away if you develop a persistent toothache.
