Does A Toothache Mean A Cavity?

Does A Toothache Mean A Cavity?When you have a pain in your tooth, you might leap to the conclusion that you you have a cavity. Dentists know that a toothache is a signal that “I need attention.” It may be that the source of trouble is arising somewhere else (for example, from pressure or infection in the sinus area.) Tooth decay is one cause of tooth pain, as is bruxism and issues with the TMJ. When a toothache lasts more than day or so, it is time to call our office and let us have a look.

Toothaches from Tooth Decay

A tooth that has an infected pocket (cavity) can certainly ache. Once the enamel layer is compromised, whether through poor brushing, a crack, or some other issue, then infection can set it. One reason we like to see you for regular checkups and cleanings is to keep a careful eye on your tooth enamel. We have dental technology to help check for soft spots, before they become infected. If you do have an infected cavity, there are ways we can repair it. We may clean and fill the area with a tooth colored filing. If some other treatment is needed, we can discuss your options.

Toothaches from Teeth Grinding

It is surprising how much pressure your jaws can exert. There is an instrument, called a gnathodynamometer, which can measure the power of a human jaw. Most people can exert well over 100 pounds of pressure. When you grind your teeth habitually, you are exerting tremendous force on your teeth and jaw. Episodes of night time tooth grinding (bruxism) can cause toothaches during the day. If we notice signs of bruxism, we may suggest a custom-fitted mouthguard that will help protect your teeth.

Toothaches from Pressures of TMJ

The temporomandibular joint (the hinge going where the jaw joins the lower face) can cause pain that is identified as a toothache, although it actually comes from the jaw. It can be hard to pinpoint the exact location of facial pain—you just know it hurts. If your teeth look healthy, and yet you are in pain we are trained in diagnosing and treating TMJ issues. TMJ problems can be related to teeth that don’t meet properly, to arthritis, to stress related issues (like clenching the jaw) and to other causes.
