Why Does My Tooth Hurt? Is It a Cavity or Something Else?

Tooth pain can come out of nowhere—sharp, dull, throbbing, or constant. But when it hits, one question often rises to the top: Is this a cavity? Knowing the answer early can make all the difference when it comes to protecting your smile. So how do you know if your toothache means decay is at play—or if something else is causing your discomfort?

At Shoreline Dental Studio in Fort Walton Beach, we believe that understanding the signs, causes, and solutions behind tooth pain empowers you to act quickly and confidently. Let’s break down what might be going on behind that ache and how to tell if a cavity could be the culprit.

What Is a Cavity?

A cavity is a small hole that forms in your tooth when bacteria in your mouth produce acids that break down enamel—the protective outer layer of your teeth. Over time, if left untreated, cavities can grow deeper, affecting the inner layers of the tooth and leading to more significant pain, infection, and even tooth loss.

These signs typically show up on the chewing surfaces of molars, between teeth, or near the gumline. Some cavities may be entirely invisible to the naked eye but detectable during a routine dental exam with X-rays.

It’s important not to wait for visible signs before taking action. Even if you don’t see a hole, tooth sensitivity or pain may indicate a cavity beginning beneath the surface.

When Tooth Pain Isn’t a Cavity

Although cavities are a common reason for tooth discomfort, they’re not the only cause. Here are other possible explanations for your toothache:

Understanding the root cause of your pain is essential for choosing the right treatment path. This is where a dental exam makes all the difference.

The Benefits of Early Cavity Detection and Treatment
