Is Pericoronitis An Infection And Can It Get Worse?

Pericoronitis is an infection. It happens when the gum tissue around a partially erupted tooth becomes inflamed and infected. And yes, it can get worse if it is not treated, sometimes spreading to the throat, face, or neck in a matter of days.

What Exactly Is Pericoronitis?

Pericoronitis is the inflammation and infection of the soft tissue that covers a tooth that has not fully broken through the gum line. This most often happens with wisdom teeth, also called third molars.

When a tooth only partially erupts, a flap of gum tissue remains over part of the crown. This flap is called an operculum. It creates a small pocket between the tooth and the gum. Food particles and bacteria get trapped in that pocket easily. Brushing and flossing cannot always reach it.

The trapped bacteria cause the gum tissue to swell and become tender. That is the start of the infection. It is a very common dental problem, especially in people between the ages of 15 and 25 when wisdom teeth typically come in.

What Causes Pericoronitis To Develop?

The main cause is the physical pocket created by the partially erupted tooth. Bacteria that normally live in the mouth multiply in that protected space.

Several factors make the condition more likely to develop:

• Poor oral hygiene in the back of the mouth
• Food getting stuck under the gum flap
• Trauma from the upper teeth biting down onto the swollen gum flap
• Stress or illness that lowers the body’s immune response
• Respiratory infections that weaken overall health

The upper wisdom tooth biting directly onto the gum flap behind the lower wisdom tooth is a frequent trigger. This repeated trauma irritates the tissue and makes it easier for bacteria to invade.

What Are The Symptoms Of Pericoronitis?

Symptoms can range from mild to severe. The early signs are often easy to miss.

Mild pericoronitis may cause:

• Slight swelling of the gum tissue
• Mild discomfort at the back of the mouth
• An unpleasant taste from pus draining out of the pocket
• Mild bad breath that does not go away with brushing

More serious infection brings stronger symptoms. Pain can radiate from the back teeth into the ear, throat, or floor of the mouth. Swelling may spread to the cheek or jaw. Opening the mouth may become difficult. Swallowing can hurt. Fever is a sign the infection is spreading beyond the local area.

The presence of pus is a clear sign of active infection. If you notice pus draining from the gum area, the infection is established and needs professional attention.

Is Pericoronitis An Infection And Can It Get Worse?

Yes. Pericoronitis is a bacterial infection, and it can absolutely get worse without treatment.

What starts as a localized gum infection can spread into the deeper tissues of the jaw and neck. This is called cellulitis. Cellulitis is a serious condition where the infection spreads through soft tissue rather than staying contained in an abscess.

In severe cases, the infection can spread to the airway and make breathing difficult. It can also spread to the bloodstream, a condition called sepsis. Sepsis is life-threatening and requires emergency hospital care.

Another complication is Ludwig’s angina. This is a rapidly spreading infection of the floor of the mouth. It can swell so much that it blocks the airway. This is a medical emergency.

The infection can also damage nearby teeth and bone. Chronic pericoronitis can cause bone loss around the affected tooth and the adjacent molar.

Do not wait to see if the infection resolves on its own. Pericoronitis rarely clears up without treatment. It may improve temporarily, but it often returns because the gum flap remains, and bacteria keep getting trapped under it.

How Is Pericoronitis Treated?

Treatment depends on how severe the infection is.

For mild cases, a dentist will clean the area thoroughly. This removes trapped food and bacteria from under the gum flap. The dentist may also rinse the pocket with a saline solution or an antimicrobial rinse. Sometimes a small instrument is used to gently lift the gum flap and clean underneath it.

Your dentist may recommend warm salt water rinses at home. Mix half a teaspoon of salt in a glass of warm water and rinse several times a day. This helps keep the area clean and soothes the tissue.

Over-the-counter pain relievers like ibuprofen can help with discomfort. Ibuprofen also reduces inflammation, which is part of the problem.

If the infection is more established, the dentist may prescribe antibiotics. However, antibiotics alone do not cure pericoronitis. The pocket still needs to be cleaned. Antibiotics control the bacterial spread, but the trapped debris must be removed.

In some cases, the dentist may need to drain an abscess that has formed. This involves making a small opening in the gum to let the pus escape.

If an upper tooth is biting down onto the inflamed gum flap, the dentist may smooth the edge of the upper tooth to stop the trauma.

For cases that keep coming back, the usual long-term solution is removal of the wisdom tooth. An oral surgeon or dentist extracts the partially erupted tooth. Once the tooth and the gum flap are gone, the infection cannot return in that spot.

Some dentists may also remove just the gum flap, a procedure called an operculectomy. This is less common than tooth extraction but can be appropriate in specific situations where the tooth is otherwise healthy and well positioned.

When Should You Seek Emergency Care?

Pericoronitis can progress quickly. Some symptoms require immediate medical attention.

Go to an emergency room if you have any of the following:

• Swelling that spreads to your cheek, jaw, or neck
• Difficulty swallowing
• Difficulty breathing
• Difficulty opening your mouth wide
• High fever
• Swelling under your tongue or in the floor of your mouth

These symptoms suggest the infection is spreading into deep tissue spaces. This is not something to manage at home or wait for a dental appointment.

If you have milder symptoms, see a dentist as soon as possible. Early treatment is simpler and less painful than treatment after the infection has spread.

Can Pericoronitis Be Prevented?

Prevention focuses on keeping the area around the partially erupted tooth as clean as possible.

Good oral hygiene is the foundation. Brush thoroughly at the back of the mouth. Pay special attention to the gum line around the partially erupted tooth.

An oral irrigator, sometimes called a water flosser, can help flush out the pocket. Direct the stream gently at the gum flap to remove food particles. This can be very effective because the stream reaches areas a toothbrush cannot.

Antimicrobial mouth rinses may help reduce bacteria in the area. Chlorhexidine rinse is sometimes prescribed by dentists for short-term use. It is not meant for long-term daily use because it can stain teeth.

Regular dental checkups allow your dentist to monitor partially erupted teeth. They can see early signs of trouble before you feel symptoms.

If your dentist recommends removing wisdom teeth before they cause problems, that recommendation is often based on the position of the teeth and the likelihood of future infection. Removing a problematic wisdom tooth early is easier than removing it after repeated infections have caused swelling and bone loss.

Why Does Pericoronitis Keep Coming Back?

Recurrent pericoronitis is common. The reason is simple: the gum flap does not go away on its own.

Once the tissue is infected and heals, the same pocket remains. Food and bacteria accumulate again. The cycle repeats.

Each episode of infection can cause more damage to the surrounding gum tissue and bone. Repeated infections may also make future episodes more painful and harder to treat.

If you have had more than one episode of pericoronitis in the same area, talk to your dentist about definitive treatment. Continuing to treat symptoms without addressing the cause will likely lead to more infections.

What Happens If Pericoronitis Is Left Untreated?

Untreated pericoronitis does not simply stay the same. It tends to get worse over time.

The infection can move from the gum tissue into the deeper structures of the jaw. This can cause severe pain and swelling. It can also damage the bone around the tooth.

In rare but serious cases, the infection spreads to other parts of the body. The most dangerous complications involve the airway and the bloodstream. Both require emergency treatment.

Untreated infection can also affect your overall health. A persistent bacterial infection puts stress on your immune system. While most healthy people can manage a localized infection, the risks increase the longer it goes untreated.

The bottom line is that pericoronitis is an infection that requires professional dental care. It will not resolve with home remedies alone. Early treatment is straightforward. Delayed treatment can turn a manageable problem into a serious medical situation.
