How Do I Know I Have a Tooth Infection?


A tooth infection can cause intense pain, discomfort, and various symptoms that might leave you wondering if it’s time to see a dentist. Understanding the signs of an infected tooth can help you take action quickly to avoid further complications. In this post, we’ll walk you through the common signs and symptoms of a tooth infection, along with what you should do if you think you’re dealing with one.

What Causes a Tooth Infection?

Tooth infections, also known as dental abscesses, typically occur when bacteria invade the inside of a tooth, usually due to untreated cavities, trauma, or poor oral hygiene. These infections can spread to the surrounding tissues, including your gums, jawbone, and lymph nodes. The infection can also cause severe discomfort and, in some cases, lead to life-threatening conditions if not treated properly.

Common Symptoms of a Tooth Infection

If you suspect that your tooth might be infected, it’s essential to look out for the following symptoms. They may indicate that you’re dealing with a tooth abscess or infection.

1. Severe Tooth Pain

A sharp, throbbing, or constant pain in the tooth is one of the most common symptoms of an infected tooth. The pain may get worse when you’re chewing or applying pressure to the tooth. This pain can radiate to your jaw, ear, or even your head.

2. Sensitivity to Hot or Cold

If you experience pain when consuming hot or cold food and beverages, it could indicate that your tooth is infected. An infection may affect the nerves inside the tooth, causing heightened sensitivity.

3. Swollen Gums or Face

Swelling around the infected tooth or on the side of your face is another telltale sign of infection. This swelling may feel painful to the touch and may get worse over time. If the swelling extends to your jaw or neck, it’s crucial to seek medical attention promptly.

4. Bad Breath or Sour Taste

When a tooth is infected, it can produce pus that drains into the mouth, causing foul-smelling breath or a sour, metallic taste. This is often an indication that the infection is deep inside the tooth or gums.

5. Tooth Discoloration

An infected tooth may change color. It could appear darker or have a greyish tint. This discoloration happens when the infection affects the inner pulp of the tooth, damaging the tooth’s nerve.

6. Pimple-like Bumps on Gums

If you notice small, pimple-like bumps on your gums near the infected tooth, this may be an abscess filled with pus. These bumps can burst and drain pus, which may temporarily relieve the pain, but the infection will still need professional care.

7. Difficulty Moving Your Jaw

An infected tooth can cause pain and difficulty when opening your mouth or moving your jaw. This is due to the swelling of the gums and surrounding tissues.

8. Fever and Malaise

As the body fights the infection, you may develop a fever or feel generally unwell. You might also experience fatigue, headaches, or body aches, which are signs that the infection is spreading or has reached a more serious stage.

9. Earache

An earache can sometimes be a symptom of a tooth infection. The pain from the infection can radiate to the ear, causing a throbbing sensation similar to an ear infection.

10. Increased Salivation

Some people with a tooth infection may experience excessive salivation as the body tries to flush out the infection. This can be uncomfortable but is usually temporary.

What Should You Do if You Suspect a Tooth Infection?

If you notice any of the symptoms mentioned above, it’s important to schedule an appointment with a dentist as soon as possible. Ignoring a tooth infection can lead to more severe complications, such as the spread of bacteria to other areas of the body, including the bloodstream. Here’s what you can expect during a dental visit:

  • Diagnosis: Your dentist will examine your teeth and gums to identify signs of infection. They may take X-rays to see the extent of the infection and check if it has spread to the surrounding bone.
  • Treatment: Depending on the severity of the infection, your dentist may recommend several treatments, such as:
    • Root Canal: This is the most common treatment for an infected tooth. The dentist will remove the infected pulp, clean the area, and seal it to prevent further infection.
    • Antibiotics: If the infection has spread or is severe, your dentist may prescribe antibiotics to help control the bacteria.
    • Tooth Extraction: In cases where the tooth cannot be saved, your dentist may recommend removing the tooth to prevent the infection from spreading.
    • Abscess Drainage: If there’s a visible abscess, your dentist may need to drain it to relieve pressure and remove pus from the area.

How to Prevent Tooth Infections

While tooth infections can occur for various reasons, there are several steps you can take to reduce your risk:

  • Practice Good Oral Hygiene: Brush your teeth at least twice a day, floss daily, and use mouthwash to remove plaque and bacteria.
  • Visit the Dentist Regularly: Regular dental check-ups can help detect cavities and other dental issues before they become serious problems.
  • Avoid Sugary Foods and Drinks: Excess sugar feeds bacteria in your mouth, increasing the risk of cavities and infections.
  • Protect Your Teeth: If you play contact sports, wear a mouthguard to protect your teeth from injury.
