Wisdom Tooth Infection: Signs, Causes, and Treatment Options

For most people, wisdom teeth are more of a hassle than they are worth. They come through in your late teens or early 20s, and by then your mouth is full. It’s that crowding that can cause a wisdom tooth infection.

Why Do They Get Infected?

Consider how difficult it is to brush the very back of your mouth. Now take a tooth that’s half in the gum, and a flap of skin is covering it. As food collects there, bacteria accumulate, and soon you have an infection starting to grow back there!

Other times it’s something else altogether:

The tooth grows out to the side but doesn’t erupt completely out of the gums.
Cavity in wisdom tooth goes unnoticed for too long
That entire area is weaker because of existing gum problems.

If you have already had problems with gums around the back of your mouth, you can bet your wisdom tooth is to blame.

What does it feel like?

It is no ordinary toothache! It is deeper, more difficult to locate, and more likely to spread.

Here's what most people say:

A persistent dull pain in the very back of the jaw.
Red, swollen, and painful gums.
Persistent foul-smelling or foul-tasting breath.

Stiffness in the jaw that makes it hard to open.

Asymmetrical cheeks.
Aching feeling that increases towards the ear or down the neck.
The toothache is accompanied by a fever.

Often, the first symptom of swollen gums and gum pain is noticed in that back corner, several days before it becomes more severe.

What is a dentist going to do?

Your dentist will check the area and have an X-ray taken. That X-ray gives them information if the infection has spread deeper into the bone or if it has begun to spread to other teeth.

Don’t put this off. If a wisdom tooth infection is left untreated, it can spread to your jaw or throat. That’s when it’s no longer an uncomfortable situation and becomes a true danger.

Treatment Options

Antibiotics are usually the starting point. They bring the infection under control, but aren’t a permanent fix on their own.

Cleaning the area works well for milder cases, particularly when a gum flap is causing the problem. The dentist flushes out bacteria and lets the tissue settle.

Extraction is where most wisdom tooth infection cases eventually end up. Molar tooth extraction is one of the most routine things dentists do, and most patients are surprised by how manageable it is.

For trickier situations, an expert oral surgeon handles the removal. If you’re nervous, reading about what tooth extraction really feels like beforehand helps a lot.

Occasionally, the tooth breaks during the procedure. When that happens, broken tooth extraction methods clear every fragment out safely.

For pain at home, warm saltwater rinses and basic painkillers take the edge off while you wait for your appointment.

Can You Prevent It?

Sometimes no, especially with impacted teeth. But good habits do help:

Brush all the way to your back teeth every time.
Flossing even when reaching back there feels awkward.
Use an antibacterial mouthwash regularly.
See your dentist before small problems grow.

Preventive dentistry is really just about catching things early. And if you’ve been told you have receding gums, pay extra attention to the back of your mouth since those areas are more exposed.
