A dental abscess is one of those conditions you don’t want to ignore. If you’ve ever had a toothache that just won’t quit, or noticed a swollen spot on your gums that feels sore to the touch, it could be a sign of an underlying infection. And while not every dental issue is urgent, an abscessed tooth is something that should be taken seriously—and looked at by a dentist as soon as possible.
In this blog from Emergency Dentistry, we’ll walk you through what a dental abscess is, what causes it, why professional care is essential, and what you can do at home to manage discomfort until your appointment.
What Is a Dental Abscess?
A dental abscess is an infection that develops inside the tooth, gum, or surrounding bone. It happens when bacteria enter the soft tissue—either through a deep cavity, cracked tooth, or gum pocket—and create a pocket of pus. That may sound unpleasant (and it is), but it’s your body’s way of trying to fight off infection.
There are different types of abscesses depending on where the infection develops:
- Periapical abscess – This forms at the tip of the tooth’s root and is often caused by decay or trauma that leads to nerve death.
- Periodontal abscess – This type starts in the gum tissue and is commonly associated with advanced gum disease.
- Gingival abscess – This occurs in the gum surface and is usually caused by trapped food or debris.
Regardless of the type, abscesses typically cause pain, swelling, and pressure—and they won’t resolve on their own. Left untreated, the infection can spread to other parts of the body and lead to more serious health issues.
Common Signs and Symptoms
Dental abscesses don’t always look dramatic, but they do tend to cause distinct symptoms. Here are some signs to watch for:
- Throbbing, persistent toothache
- Swelling in the face, cheek, or gums
- A red, swollen bump or pimple-like spot on the gum (may drain fluid)
- Pain when biting or chewing
- Bad breath or a foul taste in the mouth
- Sensitivity to hot or cold
- Fever, fatigue, or swollen lymph nodes (in more advanced cases)
If you’re experiencing any of these symptoms—especially in combination—it’s a good idea to contact your dentist as soon as possible.
What Causes a Dental Abscess?
Dental abscesses usually start with a bacterial infection. Here’s how that infection typically takes hold:
- Untreated cavities – Tooth decay that goes deep enough can allow bacteria to reach the tooth’s pulp (the soft inner tissue).
- Cracked or chipped teeth – Even a small crack can give bacteria an opening.
- Gum disease – When gum tissue pulls away from the teeth, pockets can form that collect plaque and bacteria.
- Injury or trauma – A blow to the mouth can damage the nerve inside the tooth, eventually leading to infection.
- Poor oral hygiene – Infrequent brushing or flossing makes it easier for decay and gum problems to develop.
Anyone can develop an abscess, but people with compromised immune systems or a history of dental problems may be at higher risk.
Why Professional Treatment Matters
Even if the pain seems to come and go—or if an abscess drains on its own—professional dental care is essential. Here’s why:
- The infection won’t fully go away without treatment. Pain relief is temporary if the underlying cause isn’t addressed.
- Antibiotics alone aren’t enough. They may help with swelling or infection in the short term, but the infected tissue needs to be removed for healing to occur.
- Delaying treatment can lead to complications. Untreated abscesses can spread to the jawbone, neck, or even the bloodstream in rare cases.
Depending on the severity and location of the abscess, your dentist may recommend one of the following:
- Root canal therapy – If the infection is inside the tooth, a root canal can remove the damaged tissue and preserve the tooth.
- Drainage of the abscess – For gum or periodontal abscesses, your dentist may make a small incision to drain pus and relieve pressure.
- Tooth extraction – If the tooth is too damaged to save, it may need to be removed and later replaced.
- Antibiotics – These may be prescribed if the infection has spread or if there is significant swelling or fever.
The earlier you’re seen, the more options you’ll have—and the better your chances of avoiding more complex treatment.
How to Manage Discomfort Before Your Appointment
While it’s important to schedule a dental visit as soon as possible, there are things you can do in the meantime to reduce discomfort and keep the infection from getting worse:
1. Rinse with warm salt water
Mix ½ teaspoon of salt into a glass of warm water and rinse several times a day. This can help draw out some of the fluid and soothe irritated tissues.
2. Take over-the-counter pain relievers
Medications like ibuprofen (Advil) or acetaminophen (Tylenol) can help reduce pain and inflammation. Follow the dosing instructions carefully.
3. Use a cold compress
Apply a cold pack to the outside of your cheek in 15-minute intervals to reduce swelling and numb the area.
4. Avoid heat or pressure
Avoid hot drinks, chewing on the affected side, or pressing on the sore area, which may worsen pain.
5. Stay hydrated and eat soft foods
Choose bland, soft foods like yogurt, oatmeal, or soup, and be gentle when chewing.
Keep in mind that while these tips may offer temporary relief, they are not a substitute for dental treatment.
Can Dental Abscesses Be Prevented?
Yes—many abscesses can be prevented with consistent, preventive dental care:
- Brush your teeth twice daily with fluoride toothpaste
- Floss once a day to remove plaque between teeth
- Visit your dentist for regular checkups and cleanings
- Treat cavities, gum problems, or cracked teeth early
- Wear a mouthguard during sports if there’s a risk of injury
- Avoid using your teeth to open packages or bite hard objects
Being proactive helps reduce your risk of infection and keeps your mouth healthier overall.
