Abscess on Gum: Symptoms, Causes, and Professional Dental Care

An abscess on your gum is a localized collection of pus caused by a bacterial infection. If you notice a red, swollen bump along your gumline, it is a sign that your body is fighting an infection that requires immediate professional dental attention. Because these infections do not resolve on their own and can lead to the death of your tooth or damage to surrounding bone, you should contact your dental office to get in as soon as possible. Find resources, products, and information to give your patients a healthier future.

Common Symptoms of an Oral Abscess

While some abscesses may initially present with few symptoms, they often progress to cause significant discomfort. Watch for the following signs:

• Gum or facial swelling
• Redness of skin over the abscessed gum
• Throbbing or severe toothache
• Pain while chewing
• A persistent bad taste in the mouth
• Swollen lymph nodes
• Loss of appetite
• General feeling of being unwell
• Fever (a potential indicator that the infection is spreading)

What Causes an Abscess?

Abscesses generally fall into two categories: those originating from the tooth pulp (periapical) and those originating from the gum tissue (periodontal). Common causes include:

• Tooth-Related Issues: Untreated tooth decay, cracked teeth, or damage to the tooth pulp can lead to an infection at the root tip. If left untreated, it can lead to the death of your tooth.
• Gum-Related Issues: Periodontitis (gum disease) creates deep pockets where bacteria thrive, making it a primary risk factor for periodontal abscesses.
• Trapped Debris: Small food particles, such as popcorn hulls, can become lodged between the tooth and gum, triggering an acute localized infection.

Professional Treatment Options

An abscess will not heal without intervention. Even if the abscess drains on its own, the underlying infection remains. Your dentist may recommend one or more of the following: drainage and cleaning, deep cleaning, root canal therapy, specialist care, diagnostic imaging, or Antibiotics, which may be prescribed to manage the infection, though they are not a substitute for the physical removal of the source of the infection.

• Drainage and Cleaning: Your dental professional will drain and clean the abscess to remove the source of infection.
• Deep Cleaning: If it’s a gum abscess from gum disease, you’ll need to have the space between your teeth and gums cleaned to remove bacterial buildup.
• Root Canal Therapy: A procedure to save a tooth by removing infected pulp, often necessary for abscesses caused by decay or cracks.
• Specialist Care: For a periodontal abscess, a periodontist may be consulted for deep cleaning or surgical intervention to resolve the infection.
• Diagnostic Imaging: If you have a fistula (a small tunnel draining pus), your dentist will use X-rays to locate the exact source of the infection.
• Antibiotics: These may be prescribed to manage the infection, though they are not a substitute for the physical removal of the source of the infection.

Frequently Asked Questions

Can I wait for the abscess to go away on its own?

No. An abscess is a progressive infection. If you wait for the abscess to go away on its own, you risk the death of your tooth and damage to your jawbone or surrounding tissues. Always seek professional care immediately.

What should I do if the abscess drains on its own?

Even if the pus drains, the infection is still present. You should still see your dental professional to ensure the source of the infection is fully treated.

How does a dentist diagnose the source of the infection?

If you have a fistula, your dentist will use X-rays to locate the exact source of the infection, whether it is deep within the tooth root or in the surrounding gum tissue.

How can I prevent future abscesses?

Prevention relies on consistent home oral hygiene and regular dental checkups to catch decay or gum disease before they escalate. Consistent flossing and brushing are critical to preventing the debris buildup that often triggers gum-related abscesses.
