When plaque builds up on a tooth, it produces acids that can erode the enamel surface and form a hole called a cavity. This dental problem requires a trip to the dentist. Depending on the extent of the decay, they will recommend either a filling or a crown. To prevent extensive damage to your smile, keep an eye out for the following issues that indicate a cavity.

How to Tell If You Have a Cavity

1. Sensitivity

A cavity exposes dentin, the layer of the tooth underneath the enamel. This hard tissue can be aggravated by certain temperatures and foods, which irritate the nerves and make the tooth—and the general area of the mouth—more sensitive. You could notice increased sensitivity to hot, cold, or overly sweet fare. This issue is often the earliest sign of a cavity.

2. Pain

Aches are also the result of dentin exposure and its effects on the tooth's nerves. The pain you experience can take many different forms, including gradual onset, a sudden stab of discomfort when eating triggering foods or biting down, or a worsening toothache. It's not uncommon for the uncomfortable sensation to radiate to the entire mouth or even the face.

3. Discolorations

If a cavity is large enough, you can sometimes see it when inspecting the tooth. In its earliest stages, it can look like a blemish or a series of spots, which grow progressively darker until they are brown or black. When decay is extensive, you'll see a physical hole or crater in the tooth. The pit results from corrosion caused by the acids generated by plaque bacteria.

4. Bad Breath

The bacteria that create cavities produce waste products that easily remain in the mouth. They can make your breath noticeably worse or leave a lingering unpleasant taste. If this is your only symptom of a cavity, it's still a good idea to visit your dentist. Bad breath or taste can indicate many oral health issues, including gum disease.
