Is Your Toothache Caused by a Cavity, Infection, or Something Else?

A sharp twinge while eating. A dull ache that lingers all day. Tooth pain can show up in different ways, and it’s never welcome. Whether it’s mild or severe, the question many people ask is, What’s causing it? A cavity? An infection? Or something completely different? If you’re experiencing a toothache in Issaquah, here’s how to tell what might be going on and why getting answers sooner makes a difference.

Tooth Pain Isn’t Always What It Seems

Toothaches don’t happen for just one reason. Sometimes the source is obvious, like visible decay. Other times, the pain can be referred from another part of the mouth or even unrelated to a tooth at all. Here’s a closer look at the most common causes.

Cavities: A Common Cause of Toothaches

Tooth decay starts small but can lead to big discomfort. Cavities form when bacteria in plaque break down enamel and reach the softer dentin underneath. Once the cavity grows, it can cause sensitivity to hot, cold, sweets, or pressure. You might notice a visible hole or dark spot, or you might just feel a lingering ache after meals.

Cavities won’t heal on their own, and if left alone, they can reach the tooth's inner pulp. That’s when pain becomes harder to ignore and more complex treatments may be needed.

Infections and Abscesses: When Pain Becomes Severe

An infection in the tooth or gum can cause intense, throbbing pain. Often, this means the pulp—the soft tissue inside the tooth—has become inflamed or infected. You may notice swelling in the gum or face, a bad taste in your mouth, or even a fever.

Infections require prompt care. If you wait too long, they can spread to nearby tissues or affect your overall health. Root canal treatment is a common way to remove the infection while saving the tooth.

Gum Issues That Feel Like Toothaches

Gum disease doesn’t just affect your gums. It can make your teeth feel sore, especially near the gumline. Inflammation, receding gums, and deep pockets can expose tooth roots and trigger pain. You might also see bleeding when you brush or floss.

Tooth pain related to gum problems is usually more generalized and accompanied by signs like bad breath or loose teeth. A dental cleaning and periodontal care can help manage it before the problem worsens.

Cracks, Grinding, and Other Causes

Not all toothaches are caused by decay or infection. A cracked tooth can lead to pain when biting, even if the crack isn’t visible. Teeth grinding (bruxism) can also make teeth sore, especially in the morning.

Other possible sources include sinus pressure that mimics upper tooth pain, or issues with fillings and crowns that no longer fit properly. That’s why it’s important to have any toothache evaluated. What feels like a minor issue may point to something deeper.
