Potential Causes Of Toothaches: It’s Not Always A Cavity

Pain from a toothacheNo matter how careful and thorough you are with maintaining your daily oral care, at some point in your life you will probably experience the pain and discomfort of a toothache. Although a cavity is normally the cause, tooth decay is only one of the common causes of tooth pain or sensitivity.

Tooth Sensitivity
If you experience pain when you eat or drink hot or cold food and beverages, it could signal a cavity. It could also be a sign that you have sensitive teeth, either from thinning tooth enamel or receding gums. While waiting for a dentist appointment with Dr. Pereira to confirm the cause of your sensitive teeth, using a soft-bristled toothbrush and a toothpaste designed for sensitive teeth may help ease the symptoms.

Severe Toothaches
If the pain of your toothache is sudden, sharp and stabbing, the cause may be related to a cavity or cracked tooth. However, if you experience a throbbing, constant pain when you bite down on your food, you may have an abscessed tooth or an infection. In either case, the pain should be addressed right away to avoid further complications.

Might Not Even Be Your Teeth
A less common cause of a toothache is a sinus infection. If you have pain in the upper teeth on both sides of the jaw, a sinus infection could be the cause. This type of toothache is usually combined with nasal congestion and tenderness of your sinuses.

If your ache is more identifiable as jaw pain, it may be caused by Temporomandibular joint disorders that are triggered by jaw injury, arthritis, or tooth grinding. Wisdom teeth that have not been removed could also be the cause of your jaw pain or toothache.

Good oral hygiene and routine dental care is the best way to prevent a toothache and other oral health problems. Be sure to brush your teeth at least twice a day, floss at least once a day, and visit our Darien dentist office regularly for oral examinations and a professional cleaning.

Whatever the type and severity of your tooth pain, it is important to contact us as soon as possible to schedule an appointment with Dr. Pereira for a conclusive diagnosis as to the cause of your pain and subsequent professional treatment if needed.
