PAIN OR SENSITIVITY
If one of your teeth hurts when you chew, or if you have a constant toothache, you may have a cavity.
A tooth has three layers: enamel, dentin, and pulp (where the roots and nerves are located). As the protective layer of enamel decays, the nerves in your tooth have one less layer protecting them. When a cavity forms, chewing can be incredibly painful. If the decay reaches the pulp, your tooth can become infected and result in a consistent, throbbing pain.
BAD BREATH
As a tooth decays, bacteria continue to multiply if the decay isn’t treated. Bacterial growth can lead to bad breath. If you’ve developed bad breath while continuing a good dental routine, you may have a cavity.
NOTICEABLE HOLES, PITS, OR DARK SPOTS
One of the most accurate ways to determine whether you have a cavity is to examine your teeth. If you see any dark spots, pits, or holes in your teeth, you probably have a cavity.
Because you use your back teeth for the majority of your chewing, you’re most likely to develop a cavity there.
When you find these signs, the most important thing that you need to do is to make an appointment with a dentist to examine your teeth. The dental office you choose should have a portable dental X-ray machine to ensure that your condition is detected, such as cavities.
