Common Causes of Toothache

A toothache can range from a mild discomfort to severe, throbbing pain that affects your ability to eat, sleep, or even concentrate. It’s a common dental issue that can be caused by various factors, from cavities to gum infections. Understanding the root cause of your tooth pain can help you find the right treatment and prevent further complications.

What Causes Toothache?

Tooth pain occurs when the nerves inside or around the tooth become irritated or inflamed. Here are some of the most common reasons why you might experience a toothache:

1. Cavities (Tooth Decay)

One of the most frequent causes of toothache is tooth decay. Cavities form when bacteria in the mouth break down sugars and produce acids that wear away the enamel. If left untreated, the decay can reach the inner layers of the tooth, leading to pain and sensitivity.

Symptoms:

Sharp pain when eating sweets or hot/cold foods
Visible holes or dark spots on the tooth
Sensitivity to temperature changes

2. Gum Disease (Gingivitis & Periodontitis)

Inflamed or infected gums can cause tooth pain, especially if the infection spreads to the roots of the teeth. Gingivitis is the early stage of gum disease and can progress to periodontitis if not treated.

Symptoms:

Red, swollen, or bleeding gums
Persistent bad breath
Loose teeth or receding gums

3. Cracked or Broken Teeth

A tooth that is cracked or broken due to an injury, biting down on something hard, or general wear and tear can expose the nerves inside, leading to pain and sensitivity.

Symptoms:

Pain when chewing
Sensitivity to hot or cold foods
A visible crack or chipped area on the tooth

4. Tooth Abscess (Infection)

An abscessed tooth is a serious infection that occurs when bacteria reach the inner pulp of the tooth. This can lead to severe pain, swelling, and even fever.

Symptoms:

Intense, throbbing pain
Swelling in the face or jaw
Pus or a bad taste in the mouth
Fever or swollen lymph nodes

5. Teeth Grinding (Bruxism)

Grinding or clenching your teeth, often during sleep, can cause pain in the teeth and jaw. Over time, this habit can wear down the enamel and lead to sensitivity and discomfort.

Symptoms:

Jaw pain or soreness
Worn-down or flattened teeth
Headaches, especially in the morning

6. Sinus Infection (Sinusitis)

Surprisingly, sinus infections can sometimes cause tooth pain, especially in the upper teeth. The sinuses are located above the upper teeth, and when they become inflamed, they can put pressure on the nerves in the teeth.

Symptoms:

Pain in the upper back teeth
Stuffy nose or sinus congestion
Facial pressure or headache
