👉 Toothaches are pain or discomfort that can occur in the teeth. They may be caused by a number of factors, such as damage to the teeth from chewing on hard objects, excessive grinding of your jaw, or an infection within the tooth. Toothaches can also be associated with a variety of other conditions, including sleep apnea and certain types of gum disease. If you are experiencing a toothache, it is important to consult with a dentist for proper diagnosis and treatment.
