How To Tell If You Have A Cavity

There are a number of signs that can alert you that you may have a cavity. Below you will find some of the common symptoms.

1. Toothache: If you have an ongoing ache in one or more of your teeth, it can indicate that you have a cavity. Pain is actually one of the most common symptoms of a cavity as your body is alerting you that there is something wrong. The aching may come on suddenly or as a result of something you eat. You may also feel pain or intense pressure when you chew food or bite down on something.
2. Hot and Cold Sensitivity: If you eat something hot or cold and the sensitivity of the temperature lingers longer than usual, you may have a cavity. When the enamel on your tooth starts to wear away, it can affect the dentin in your teeth. This is the hard tissue layer right below the enamel. It is essentially your tooth’s second layer of defense. Dentin contains tiny hollow tubes, so when there isn’t enough enamel to protect the dentin it can cause sensitivity. This is because the foods that are hot and cold can stimulate the cells and nerve inside your tooth created a feeling of lingering sensitivity.
3. Sensitivity to Sweets: Similar to a hot and cold sensitivity, a lingering sensitivity to sugary foods and drinks can also be a sign of tooth decay. This is also a result of damage to the enamel which often leads to a cavity.
4. Tooth Stains: These may first appear as white spots and become darker as the tooth further decays. It may become brown or black, but it is generally visible on the surface of your tooth.
5. Pits or Holes: If you notice that your teeth are staining and becoming darker, a hole or pit will likely follow if your cavity is untreated. While you may not be able to visibly see it, you may be able to feel it if you run your finger (wash your hands first!) or tongue over the tooth. However, some holes may not be seen or felt but you still may have a cavity. Keep a close eye on your teeth if there is discoloration and contact your dentist as soon as possible.
