A hard and white bump on gums is a common dental condition that affects many people at some point in their lives. These bumps range from small, harmless bumps to large, painful lumps and swelling that require medical attention. They exist in various sizes and shapes and may affect one or several gum areas between your teeth.

Gum bumps are common among people with periodontal disease or those who recently had dental surgery. These cases allow food and plaque to build up in your gum’s pockets, resulting in bacterial overgrowth. This buildup causes bleeding, swelling, and redness of your gums.

Most bumps, lumps, and swellings on gums are harmless yet irritating; others are symptoms of a severe bacterial infection. That’s why you should visit your dentist if you notice a bump on your gum. These specialists help treat the bump, swelling, or soft, painless lump on your gum, so you achieve optimal oral health.

This guide is your go-to resource for understanding the signs of gum problems. It will cover everything you need to know, from identifying different signs and causes of swelling around one tooth to exploring treatment options. This guide is here to help you understand what is going on with your mouth and how best to care for it.

What Is a Gum Bump?

A white bump on gums is an abscess that forms on your gum due to bacteria or plaque buildup and tooth decay. This causes an infection beneath your gum cavity line or surface, affecting one or several teeth.

Gum bumps refer to boils that appear as lumps or swellings on the gum. Some gum bumps are small and harmless, while others are large and painful. They are a sign of bacterial infection, which is easily treatable.

Types of Gum Bumps

Gum bumps, boils, or abscesses take different forms depending on where they develop. Here are the common types of gum bumps to watch out for:

Periodontal Abscess

A periodontal abscess is a common gum bump resulting from a bacterial infection in the supporting gum tissues. It’s a painful dental emergency that affects patients with or without active gum disease and requires prompt management.

Periapical Abscess

A periapical abscess is a boil or lump forming close to or at the tooth’s root. It results from an infection that forms in the teeth and spreads to the gums due to tooth decay or trauma.

Gingival Hyperplasia

This gum bump develops due to an overgrowth of gum tissue and appears as a raised red bump on the gums. Medications, hormones, or certain medical conditions usually cause it. Treatment often involves professional cleaning and the use of topical medications.

Consider visiting a dentist immediately if you notice gum bumps, swellings, or lumps. They create an effective treatment plan and recommend solutions to prevent gum bumps from growing into serious issues.

Why Is My Gum Swollen Around One Tooth

Having swollen gum around one or several teeth is alarming for many people. Your gum may swell around one tooth due to various reasons, such as:

Poor Hygiene

Failure to brush and floss properly causes the accumulation of food debris in your periodontal pockets. Such debris leads to tooth decay and inflammation, resulting in gum swellings.

Gum Disease

A bacterial infection may affect the gum tissue surrounding your tooth, causing inflammation. This inflammation may cause periodontal disease that causes swollen gums, bleeding gums, gum recession, and loose teeth.


An untreated tooth cavity allows bacteria to infect your tooth, resulting in an abscessed tooth. Such a tooth becomes painful, and the jaw or gums around it swell.


You may experience swelling around the affected tooth if you have injured your gums due to trauma or biting too hard. Treatment usually involves cleaning the area and rinsing with a salt-water solution.

You should see a dentist if your gum has swollen around a tooth for the above reasons. These professionals provide effective treatments to prevent the issue from spreading further. You achieve excellent oral health, regain your smile, and enjoy eating, biting, or talking.

Causes of Gum Bumps, Lumps, and Swellings

A white bump on gums is not often a medical emergency, as most are harmless. The soft painless lump on the gum, however, can lead to gum inflammation, irritation, and swelling if left untreated. Below are the common causes and symptoms of hard bump on gums:


Dental cysts are slow-growing, tiny bubbles or sacs filled with fluid, air, or other soft materials. that are common in the mouth. They develop on the gum tissues surrounding your teeth, including around the roots of buried or dead teeth. That’s due to infection or trauma to the gums.

Cysts are sometimes painful and cause swelling around the bump if they’re too large. Such cysts exert pressure on your teeth, weakening your jaw over time. Treatment usually involves surgical removal of the cyst and antibiotics.

Canker Sores

A canker sore is a tiny mouth ulcer or pimple on the gums surrounding your teeth. They are often harmless yet painful while drinking and eating. These sores manifest as yellow or white spots with a reddish border and flat or relatively raised bumps.

Canker sores usually heal on their own in a few weeks. Consider applying an over-the-counter analgesic to help ease the pain.


An abscess is a tiny collection of pus caused by a bacterial infection on the gums. It may feel like a warm, soft yet painful bump. You experience a throbbing pain that immediately worsens when you rest or lie down. Visit your dentist immediately if you notice you have an abscess to prevent further gum infection.

Oral Fibroma

A fibroma is the most common cause of a white bump on gums. It’s a noncancerous lump that develops on gum tissues injured or irritated by dentures or other dental devices.

Fibromas are harmless and often feel like hard, dome-shaped, soft lumps on the gum. They sometimes appear as dangling skin tags and look either lighter or darker than your gums. The best part is that fibromas don’t need treatment except for surgery when they grow larger.

Oral Cancer

Oral or mouth cancer affects any part of your mouth, including the gums. A cancerous tumor develops on your gums and appears as a small bump, lump, or thick skin. It is a bleeding sore that won’t heal or a red or white patch on your gums. Treatment usually involves surgery or chemotherapy, and radiation therapy.

Oral Pyogenic Granuloma

An oral pyogenic granuloma is a red bump that forms in the mouth due to irritation from braces or dentures. It is a small, mucous-covered, noncancerous growth that appears as swollen, blood-filled lumps that bleed easily. Treatment typically consists of surgically removing the lump growth.

The causes of gum bumps, lumps, and swellings vary depending on factors like oral health and trauma. Visit a dental specialist if you notice a white bump on your gums for proper treatment.

Potential Issues with Treating and Preventing White Bump on Gums

Treating gum bumps, lumps, and swellings depends on the cause and is key to improving your oral health. The best option is to seek medical help from an experienced dentist as soon as possible. They will:

  • Prescribe medications like antibiotics or anti-inflammatory drugs to help reduce swelling and pain.
  • Recommend more invasive treatments like surgery to remove the bumps depending on their severity.
  • Advise you to brush or floss with special medicated mouthwashes regularly to prevent gum bumps.
  • Recommend avoiding certain foods that could aggravate symptoms of gum bumps, lumps, and swellings.
  • Provide more invasive treatments like surgery depending on the severity of the condition to treat the affected area.

Taking these measures helps you deal with any potential issues associated with gum bumps quickly and effectively. Treating gum bumps, swellings, and lumps becomes easier, so you eat, bite, or chew food without feeling pain.
