5 Common Causes of Toothache

It’s happened to nearly everyone at one point or another—that dull aching in the back of your mouth that you can’t ignore. Toothaches are irritating, stressful, and painful. But what exactly causes this common oral annoyance? Let’s take a look at five of the most common causes of toothaches.

Gum Disease

Gum disease, as its name suggests, is an infection of the gums. If you have gum disease, you might notice the area around your teeth has become red and inflamed. If left untreated, gum disease can lead to tooth pain because the bacteria may eventually make their way to the root of your teeth.

Tooth Decay

Commonly referred to as a cavity, tooth decay occurs when bacteria erode your tooth’s enamel. Tooth decay is one of the most common causes of toothaches and may become more severe over time if not treated by a professional.

Sensitive Teeth

Some people are born with a thinner layer of dentin, the tissue that lies beneath the hard enamel of the teeth. If you have thin dentin, you might have chronically sensitive teeth—and you might experience a toothache when eating certain foods or drinking cold beverages.


Traumatic injuries occurring from sports or accidents can cause cracking in your teeth, leading to pain. If you’re experiencing severe tooth pain following a traumatic accident, call for emergency dentistry in Ardmore, PA as soon as possible.


An abscess occurs when a cavity or section of decay is left untreated and bacteria infect the pulp of your tooth’s root. An abscess can be incredibly painful, especially when chewing.

While most toothaches can be treated at home until you can get an appointment with your dentist, searing pain might be a symptom of an urgent dental issue.
