What are Signs of Tooth Decay?

Tooth decay, for some, is inevitable. Avoiding the teeth from decaying can only be done through proper oral hygiene care. However, even with proper dental care, the teeth may still decay.

It’s important to know the signs and symptoms of tooth decay so that a dentist can immediately take the necessary steps to treat the decaying teeth. If tooth decay goes on for too long, cavities may appear or even possible tooth rotting. Seeing the dentist as soon as any of the following signs appear is vital in maintaining healthy dental hygiene.

Tooth decay is more common than people think and there are many signs that can alert someone that their teeth are decaying.

Signs of tooth decay

Tooth pain

If a person is experiencing a lot of pain in their teeth, then this may be a sign that they are experiencing tooth decay. When the teeth begin to decay, they are imposing on the roots, which are where the nerves live. If the nerves begin to experience damage such as decay, then the pain will commonly occur. If the pain is constant or even if they are random sharp pains, then seeing the dentist immediately is important.

Uncommon colored spots

If the teeth begin to form spots of unusual colors on the surface, then this could be a sign of tooth decay. Typically, the colored spots might be brown, black, or grey which are all unnatural colors for the tooth. When the teeth begin to decay, they don’t stay true to their natural white color. But rather, they start the process of decay which as one can imagine, results in brown or black colored spots on the surface.


Tooth sensitivity is a common occurrence in a lot of dental problems ranging from cavities to root canal side effects. However, if there tends to be a major spike in sensitivity to the teeth when consuming hot or cold foods, then this might be a sign that the teeth are beginning to wear down and decay.

Visible holes or pits

It’s important to pay close attention to the teeth every day because it is always possible that things like decay may begin to affect the teeth. Keep an eye out for visible holes or pits on the surface of each tooth. If holes or pits are present, be sure to see the dentist immediately. Holes and pits can be dangerous because bacteria or food particles may seep in, causing more damage (than just decay) to the teeth.


Tooth decay can lead to very dangerous conditions for the teeth and the mouth as a whole. It’s vital to practice proper oral hygiene to avoid decay at all costs, but knowing what the signs of decay are is just as important. If decay is caught early enough, a dentist can do their best to restore the remaining tooth.
