What Is A Gum Boil?

A gum boil is a small, raised bump on your gums. To better understand what is gum boil, imagine a swelling or abscess that resembles a pimple. It is often filled with pus and indicates something deeper that requires immediate attention. In other words, this bump is your body's way of hinting at a problem around a tooth or the gums. 

Though mostly harmless, these bumps on the gums often arise from bacterial infections and poor oral hygiene. Infection of the gums may be a result of tooth decay, trapped food debris or gum disease. It can eventually lead to pus-filled swellings. Whether they hurt or not, addressing them early on is key to preventing the spread of infection and other complications.

Types Of Gum Boils

A gum abscess or boil occurs specifically in the gums, unlike a dental abscess that forms at a tooth root or its surrounding gum area. Based on where they occur, they are categorised into three types:

  • Gingival Abscess: A small pus-filled infection that appears in the gumline. It affects only the soft gum tissues near the edge of the gums or between the teeth. It does not involve the tooth or deeper structures.

  • Pericoronal Abscess: This type of abscess forms on the gum tissues surrounding the crown of a partly erupted tooth. It is often linked to an impacted wisdom tooth. 

  • Periodontal Abscess: It affects the supporting gum tissues of teeth. A periodontal abscess usually forms when bacteria infect the gum pockets. Untreated plaque deposits, gum disease, faulty dental procedures or gum injury can deepen gum pockets, making them hard to clean and trapping bacteria easily. This leads to gum infection and swelling near the tooth roots.

If you consider how they differ from a dental or periapical abscess, a gum abscess affects the gum tissues around the tooth. Whereas a periapical abscess starts inside a decayed tooth, reaching its pulp and the tip of its root.

Gum Boil Symptoms

Most gum boils are painful. You may also feel a bump on gum tissues as you probe the area with your tongue or notice it when you look into your mouth in a mirror. Besides, various other signs can indicate a progressing infection. Some are even linked to early or severe gum disease symptoms. 

Knowing the common symptoms of a gum boil is vital for timely detection and treatment. They include:

  • Small, raised, soft or tender bump on the gum

  • Red, swollen gum tissues that bleed easily

  • Warm, shiny or stretched gum tissues

  • Sudden and throbbing pain when chewing or biting

  • Persistent swelling that becomes noticeable over time

  • Pus-filled gum pocket and pus discharge from the gum

  • Bad breath and a bad taste in the mouth due to leaking pus

  • Sensitivity to heat or cold in a tooth near the abscess

  • Discomfort when applying pressure to the area

  • Possible earache, nausea and fever

If you notice any of these signs, consult a dental professional for proper diagnosis and treatment.

What Are the Main Causes of a Gum Boil?

The most common gum boil causes are bacterial infection and poor dental hygiene. Without proper oral care, bacteria and plaque build up at the gumline, leading to infection. Plaque, a colourless film of bacteria and food particles, forms along the gumline. If not removed by daily brushing and flossing, it accumulates and hardens into tartar.

Plaque and tartar buildup can deepen the gum pockets. They house harmful bacteria that infect and irritate your gum tissues. Moreover, untreated gum infections and injuries can also increase the risk of periodontal abscesses. The major risk factors and causes of gum boils include:

  • Poor oral hygiene and bacterial infection

  • Smoking or chewing tobacco, which promotes plaque and tartar buildup

  • Crooked teeth that are hard to keep clean

  • Untreated dental problems like tooth decay and periodontal disease

  • Impacted or partly erupted wisdom teeth

  • Injury or trauma to the teeth or gums (like a cut on the gums or chipped tooth that offers an entry point for bacteria)

  • Weakened immune system, which makes it difficult to fight off infections

  • Health conditions such as diabetes, pregnancy, and genetic factors that increase the risk of gum problems

How to Treat a Gum Boil?

If you notice the symptoms of a gum boil, book a dental appointment immediately. Left untreated, the infection may spread to your jawbone or teeth, eventually leading to tooth loss. Timely treatment is crucial to prevent the infection from entering the bloodstream and causing life-threatening conditions.

A gum boil treatment aims to remove the infection, clear the affected area and ease pain. Dentists may use X-rays for diagnosis and suggest the right treatment. Individual treatment options may vary based on the infection’s severity. Typically, it includes:

  • Draining the infection: The dentist gently drains the pus from the abscess. This reduces pressure and pain.

  • Clean the pocket: Gum pockets are cleaned and irrigated with salt water. The tooth surface may be lightly scaled to remove plaque and bacteria.

  • Debridement: A small amount of soft tissue around the abscess is cleaned. Removing the infected portion helps prevent reinfection and supports healing.

  • Medication: Your dentist may prescribe pain relievers and antibiotics to ease pain and reduce infection.

  • Other dental treatments: If the abscess is linked to severe tooth decay, root canal treatment may be suggested. Root canal therapy may not suffice if the tooth is badly damaged, in which case tooth extraction may be recommended. Deep cleaning and gum surgery may be suggested for moderate to severe gum disease.

  • Follow-up care: Good oral hygiene and regular check-ups help prevent future infections and abscesses.


If you are wondering how to treat gum boil at home, avoid home remedies, as they can be potentially unsafe and harmful. Though some home care tips can ease discomfort temporarily, professional treatment is crucial for an effective cure and long-term relief.

What Should You Do If a Gum Boil Pops?

If your gum boil popped, the pressure may seem to reduce. However, the infection may still remain in the gum tissues. A popped bump on the gum does not mean it has healed; only the pus has drained temporarily. The infection may still spread to the nearby tissues, causing the boil to return.

So, whether a gum boil pops or not, seeking professional treatment is important. A dentist can address the underlying cause of the infection and help prevent the boil from returning or spreading. Hence, as soon as a boil pops, schedule a dental checkup. The following tips can help until then:

  • Rinse your mouth with lukewarm salt water to clean the area

  • Avoid touching, probing or squeezing the boil

  • Use a soft toothbrush to clean gently near the affected area

  • Avoid home remedies with kitchen staples like clove oil, turmeric or hydrogen peroxide

How to Prevent Gum Boils

Good oral hygiene habits are important when considering how to treat gum boil at home. Besides, they are key to preventing gum problems. Keeping your teeth and gums clean and healthy can help reduce your chances of infections, abscesses, and gum boils. The following preventive tips can go a long way in protecting your gum health:

  • Brush your teeth and gums gently twice everyday.

  • Ideally, use a soft toothbrush and an antibacterial fluoride toothpaste for added protection.

  • Floss once daily to remove plaque and bacteria from between teeth and along the gumline.

  • Rinse well after every snack or meal. Use a dentist-recommended antibacterial mouthwash.

  • Ensure regular dental checkups and cleanings. Get the early signs of gum disease and tooth decay treated before they worsen.

  • Limit sugary foods to manage harmful bacteria. Avoid hard foods that may injure your gums.

  • Avoid smoking and tobacco use.

At-Home Care and Remedies

A gum boil needs professional dental care. Yet, you may be looking for simple ways to manage discomfort until your dental visit. However, not all home remedies are safe or scientifically backed. So, it is best to approach home remedies with caution. That said, gum boil treatment at home with simple care tips can provide temporary relief while supporting your dental health. These include:

  • Saline rinse: A warm salt water rinse is a classic remedy that many people consider. The antimicrobial properties of salt can help control infection. It also soothes pain and irritation while gently cleaning the affected area.

  • Oral care routine: Brush twice, floss once and rinse properly. It helps control the infection while supporting good oral hygiene.

  • Antibacterial toothpaste: Dentists recommend using a fluoride toothpaste for daily brushing. An antibacterial formula can offer extra protection against harmful bacteria.

For example, consider the Colgate Total toothpaste. It is designed with a dual zinc plus arginine formula that fights germs and protects your mouth for 12 hours. It actively seeks out bacteria on teeth, gums, cheeks and tongue for better protection compared to an ordinary toothpaste. This makes it an ideal choice to prevent oral health problems and promote excellent oral hygiene.

  • Daily habits: Choose a healthy diet that supports your oral health and does not worsen any existing dental issues. Stay hydrated to promote enough saliva flow in the mouth and a healthy oral environment. Quit smoking and tobacco use.

Home treatment can only help manage a gum boil temporarily. They do not address the underlying infection and cannot replace professional care. A timely treatment is crucial to protect your smile. Effective prevention starts with good oral hygiene. Daily oral care habits, use of antibacterial toothpaste and regular dental visits can go a long way in keeping your gums healthy.
