5 Signs You Have a Cavity

It is essential to be proactive and preventative in your dental care, especially when it comes to common tooth issues. The best way to do this is by knowing five common signs you have a cavity. If you are experiencing tooth pain, sensitivity, or notice a change in how your teeth fit together when biting down, then it might be time for a visit to your External link opens in new tab or windowdentist in Fairbanks.

1. You experience tooth pain.

Pain is often a sign that there's something wrong with your teeth. The tooth that has a cavity may be causing you pain, and it probably makes things difficult when you try to brush or floss the area of an infected molar.


Other patients find they're unable to chew on certain foods because of sensitivity in their gums due to exposed dentin nerves. This causes much discomfort during mealtime and anytime something comes into direct contact with the exposed nerves. Cavities can also often lead to large holes in the teeth, which means your tooth pain will progressively get worse if you don't get it checked out.

2. Your teeth are sensitive to hot or cold food and drinks.

Sensitivity towards hot or cold food and drinks might be a sign that you have a cavity. This sensitivity will increase over time as the decay gets deeper into your tooth, making it more difficult to eat or drink certain things.


It can sometimes be painful to bite down on foods like apples, carrots, or celery because of how painful it is for teeth to come into contact with each other or other hard substances.

3. There is a change in the color of your teeth.

If there is dark coloration on your teeth, it might be time to see your dentist. This is typically caused by tooth decay that has been left unchecked and is a sign of a cavity that’s forming or an already established cavity.


The color change could also be from something you have consumed recently, so it's important not to jump to conclusions about what this symptom means without consulting your dentist first.

4. You have bad breath.

If you notice that the smell of your breath is becoming increasingly worse, and it's not just because you ate garlic, then there may be a cavity forming.


Bacteria typically cause decaying proteins from food particles on or near teeth that produce sulfuric acid as a result. If you're experiencing persistent bad breath that is difficult to mask with mouthwash or chewing gum, then it may be time for a dental checkup!

5. Your gums are swollen, red, and sore.

If the bacteria in the cavity is close to the gum line, it can cause bleeding and swollen gums.

This is because bacteria from food particles and saliva constantly build up in your mouth and cause inflammation or irritation.


If this happens, it may also be a sign of gingivitis. Get a diagnosis from a professional before trying to treat it.
