5 Causes of Swollen Gums and When to See a Dentist

Reviewed by Dr. Tiffany Deaton

Reading time: four minutes

Swollen gums can cause tenderness, discomfort, redness, and irritation around the teeth and gumline. While swelling may sometimes be temporary, it can also be a sign of an underlying dental issue that should be evaluated by a dentist.

With two convenient locations in Summerville, Deaton Dental Associates and Flowertown Dentistry provide comprehensive dental care for patients of all ages.

What Causes Gums to Swell?

Gum swelling is usually a sign of inflammation or irritation in the tissues surrounding the teeth. While some causes are temporary, others may require treatment to prevent the problem from worsening.

1. Food Trapped Between Teeth

One of the most common causes of localized gum swelling is food trapped between the teeth or beneath the gumline. Small food particles can irritate the surrounding tissue and create inflammation. You may notice tenderness, redness, or swelling around a single tooth. In many cases, careful brushing and flossing can remove the debris and allow the area to heal.

2. Gingivitis

Gingivitis is the earliest stage of gum disease and develops when plaque accumulates along the gumline.

Common signs of gingivitis include:

  • Red or swollen gums
  • Bleeding while brushing or flossing
  • Tenderness along the gumline

When identified early, gingivitis can often be improved with professional dental cleanings and consistent oral hygiene at home.

3. Gum Disease

If gingivitis is left untreated, it can progress into periodontal disease. Periodontal disease affects the gums, supporting tissues, and bone surrounding the teeth. As the condition advances, pockets may form around the teeth, allowing bacteria to collect below the gumline.

Other symptoms may include:

  • Bleeding gums
  • Persistent bad breath
  • Gum recession
  • Loose teeth in more advanced cases

Early treatment can help slow or stop further damage to the supporting structures of the teeth.

4. Tooth Infection or Abscess

A tooth infection can sometimes cause swelling in the gums near the affected tooth. When bacteria reach the inner portion of a tooth, an abscess may develop. This can create pressure and inflammation in the surrounding tissues.

Other signs of a tooth infection may include:

  • Persistent tooth pain
  • Pain when chewing
  • A pimple-like bump on the gums
  • Bad taste or drainage
  • Swelling around one tooth

Dental infections should be evaluated promptly to prevent the infection from spreading.

5. Trauma or Irritation

The gums can also become swollen after irritation or injury. Minor irritation often resolves as the tissue heals, but ongoing swelling should be evaluated by a dentist.

Common causes include:

  • Brushing too aggressively
  • Flossing too forcefully
  • Eating hard or sharp foods
  • Irritation from orthodontic appliances
  • Rough edges on dental restorations

When Should You See a Dentist for Swollen Gums?

While mild irritation may improve on its own, persistent gum swelling should not be ignored.

It is a good idea to schedule a dental exam if you experience:

  • Swelling that lasts more than a few days
  • Bleeding gums
  • Pain when chewing
  • A bump on the gums
  • Bad taste or drainage
  • Repeated swelling in the same area
  • Facial swelling or fever

A dental examination can help identify the cause and determine whether treatment is needed.

Drs. Rhett Deaton and Tiffany Deaton provide comprehensive dental exams for patients experiencing swollen gums and other oral health concerns. During an examination, they evaluate the gums, teeth, and surrounding oral tissues to determine the source of inflammation and identify any underlying conditions that may require treatment.

FAQ

Why are my gums swollen around one tooth?

Swelling around one tooth may be caused by trapped food, localized gingivitis, gum disease, a tooth infection, or irritation to the surrounding tissue. A dental exam can help determine the exact cause.

Can swollen gums go away on their own?

Minor irritation may improve on its own, especially if caused by trapped food or mild trauma. However, swelling caused by infection or gum disease usually requires professional treatment.

Can food stuck between my teeth cause gum swelling?

Food trapped between the teeth or beneath the gumline can irritate the surrounding tissue and cause localized swelling, tenderness, and redness.

Is gum swelling always a sign of infection?

Gum swelling can be caused by several conditions, including gingivitis, gum disease, irritation, injury, or trapped food. However, persistent swelling should be evaluated by a dentist.
