When you think of a cavity, you might imagine a dark spot or pit in the biting surface of a molar or nestled in between two teeth. However, it’s also possible to develop a cavity along or below the gum line, on the flat side of a tooth. Due to their location, addressing gum line cavities requires a delicate approach. Join us to learn what causes these cavities and explore your treatment options.

What is a gum line cavity?

A gum line cavity is precisely what it sounds like: decay near your gumline. Let’s explore how these cavities form and how they differ from other types:

Poor oral hygiene
Receding gums
Dry mouth
Acidic or high-sugar diet
Improper brushing and flossing techniques
Tobacco use

How to tell if you have a gum line cavity

Symptoms of a gum line cavity can vary, but you may experience increased sensitivity, discoloration, inflammation, or bleeding. You might notice food particles regularly accumulating in the same place, or see a small notch or groove in the tooth surface.

In some cases, bad breath may also indicate tooth decay. If you suspect you have a gum line cavity, a visit to your dentist is essential to prevent severe complications like periodontal disease.

Gum line cavity vs other cavities

The location of gum line cavities sets them apart from other types of dental decay. These pits are more common in older adults with some degree of gum disease, but may appear in patients of any age. While your dentist can fill a standard cavity with ease, it may be more difficult to treat a gum line cavity, thanks to the close proximity to delicate soft tissues.

How is a gum line cavity treated?

Depending on the severity of your gum line cavity, your dentist may choose one of the following treatment options:

Dental fillings

Dental fillings are the most common solution for a minor gum line cavity. During this procedure, your dentist will remove decayed material, eliminate any harmful bacteria, and fill the hole with a composite material or amalgam matching the color of your natural tooth. If the cavity affects the tooth roots, they may use a glass ionomer that releases fluoride to offer long-term protection against future cavities.

Root canal

Root canal procedures often have a bad reputation, but they’re the gold standard for treating severe cavities that have infected the tender nerve or pulp within a tooth. It’s fairly rare to require a root canal for a gum line cavity, but it may be necessary if decay has affected an exposed root.

Gum surgery

In some cases, surgery may be required after a filling in a gum line cavity, especially if receding gums are a factor. This procedure may involve reshaping the tissue or placing a gum graft to cover an exposed root.

Fluoride treatment

While generally used as a preventive measure to inhibit cavity formation, topical fluoride treatments may be used in conjunction with fillings to protect against future damage.

How to prevent gum line cavities

Preventing gum line cavities is all about combining great oral hygiene practices with routine professional care. Here are a few tips to help you avoid tooth decay:

Practice good oral hygiene

If you brush and floss twice a day, you’re already on the right track to preventing cavities. Using a soft-bristled toothbrush and a fluoride toothpaste, gently brush at a 45-degree angle to eliminate plaque and discourage the build-up of hardened tartar.

Get regular checkups and cleanings

You might assume that brushing and flossing are enough to prevent gum line cavities, but that isn’t the case. Regular dental cleanings and checkups are an integral component of proper oral hygiene. Dentistry professionals can identify areas of concern that you may not even be able to see yourself. Schedule a routine cleaning every six months to maintain optimal oral health.

Limit sugary and acidic foods

Cavity-causing bacteria thrive on sugary, acidic foods and drinks, which are the same substances that soften enamel and dentin. If your diet includes lots of sweets, sodas, citrus, and wine, you’re creating the perfect environment for these microorganisms to take hold.

Cut down on these treats, and drink water after indulging to neutralize your pH. Of course, be sure to brush and floss to eliminate any particles left behind before they cause a gum line cavity.
