Cavities have different signs and symptoms depending on their size and position. You may not have any symptoms at all when a cavity is just getting started. As the decay progresses, it can produce symptoms such as:

  • Toothache, spontaneous pain or pain that occurs without any apparent cause
  • Tooth sensitivity
  • Mild to sharp pain when eating or drinking something sweet, hot, or cold
  • Visible holes or pits in your teeth
  • Brown, black or white staining on any surface of a tooth
  • Pain when you bite down

When to see a dentist? It's possible that you're not even aware that a cavity is forming. Even if your mouth feels good, it's necessary to have daily dental check-ups and cleanings. If you have a toothache or mouth pain, you should see your dentist as soon as possible.

Cavities can form in a single tooth or between two teeth, so understanding the signs and symptoms can help you stay on top of things.

Here is a list of seven warning signs that could indicate that you have a cavity between your teeth. It's possible that these aren't the same for everybody. If you think you may have a cavity, make an appointment with your dentist.

1. Heat or cold sensitivity

Since the cavity is wearing away at your enamel, heat or cold sensitivity is a common side effect of cavities. When the enamel on your tooth deteriorates, the nerves underneath become more vulnerable. You can have a cavity if you bite into your dinner and feel a tinge of pain or residual pain after a hot meal or drink.

2. Pain

One of the most common reasons people visits the dentist is for tooth pain. This is not the same as tooth sensitivity. Your mouth may be in chronic pain rather than experiencing pain in response to stimuli such as hot food or a cold drink.

This can be anything from a minor toothache to a serious one. When you have tooth pain, regardless of how severe it is, you should see your dentist.

3. Halitosis (bad breath)

Another indication that you might have a cavity is bad breath, also known as halitosis. Although some people can overlook minor tooth pain, bad breath is much more difficult to overlook. It is a common reason for people to visit their dentist.

4. Discoloration

Another symptom of a cavity is dark spots on your teeth. Before holes develop in the tooth, dark spots usually appear.

5. Holes

A hole in your teeth is normally an indication that you have a serious cavity. This means that, although your cavity can still be repaired, it will likely require more effort than simple cavities. It's best to try to capture cavities before they progress to this point.

6. Pus

Pus development is similar to the formation of holes, indicates that your cavity has advanced and that you can seek dental treatment right away. Pus can signify the formation of an abscess in your cavity.

7. Chipping or breaking

Several items, such as eating hard candy, can cause chipping or breaking. To avoid bacteria from getting in and causing infection, both the cavity and the damaged tooth would need to be patched.

There are several signals that a cavity is starting to form. Several red flags indicate that an existing cavity is becoming larger. The following are some of the most common indications of how to tell if you have a cavity.

1. Hot and cold sensitivity

Lingering sensitivity after consuming hot or cold food may be a symptom of a cavity. When the enamel on your tooth begins to peel away, the dentin, which is the hard tissue layer under the enamel, will be affected. Dentin is made up of thousands of microscopic hollow tubes.

2. Lingering sensitivity to sweets

While heat and cold sensitivity is the most common symptom of tooth decay, Dr. Inna Chern, DDS, founder of New York General Dentistry, says a residual sensitivity to candy and sugary drinks may also be a sign of tooth decay.

3. Toothache

A persistent ache in one or more of your teeth may be a sign that you have a cavity. In fact, one of the most common signs of a cavity is pain. This ache may occur unexpectedly or as a result of something you eat. This involves discomfort and pain in or around your mouth. When you bite down on food, you can also experience pain and pressure.

4. Staining on the tooth

White spots on your teeth can be the first sign of a stain. The stain will darken as the tooth decay progresses. Cavity staining may be brown, black, or white, usually on the tooth's surface.

5. A hole or pit in your tooth

Suppose the white spot on your tooth (which indicates the beginning of a cavity) gets worse. In that case, it can turn into a void or pit that you can see in the mirror or feel as you run your tongue along the surface of your teeth.
