Swollen gums are a fairly common occurrence and most often a sign of something that's easily treatable. But what does it mean if your gums are swelling around a single tooth? And what can you do to treat it? Here are some of the most common causes of swelling around a single tooth, along with treatment advice to keep you smiling.

1. Food Debris

If you have swelling around just one tooth in your mouth, it may be because you didn't get food debris out from under your gums, which can cause decay and inflammation. If you get the debris out early by brushing and flossing, the swelling may go away. If you're unable to resolve the problem on your own within a couple of days, make a visit with your dental professional. Left untreated, this can cause gum disease, which leads us to number 2...

2. Gum Disease

According to the National Oral Health Survey of India, 41.2 percent people in 35-44 years age group are affected from gum disease. This condition is caused by bacteria built up around your gumline and has turned into plaque (a soft, sticky, colourless film). In its earliest stages (gingivitis), you may experience red and swollen gums. If your gingivitis goes untreated, your inflammation can develop into a more severe condition called periodontitis. Periodontitis can cause your tissue to recede, bone to wear away, teeth to loosen, and your teeth could even fall out. Luckily, gum disease is preventable by practicing good oral hygiene, and its more severe stages can be treated with deep cleaning (and, in some cases, surgery).

2. Abscessed Tooth

An abscessed tooth is a small sac of pus in your gums caused by a bacterial infection. Most often, bacteria reach the blood vessels and nerves in your tooth's pulp (the inner chamber) because of tooth decay or a broken or fractured tooth, but tooth abscesses can also be the result of gum disease. Tell-tale signs include throbbing pain, red or swollen gums, a swollen jaw or face, a tender or sore tooth, a fever, and even a salty taste in your mouth. See your dental professional for treatment right away if you think you have an abscessed tooth. They usually aren't dangerous, but in rare situations, the infection can spread and create serious complications.

2. Other Potential Causes

Other causes of swollen gums that could potentially occur around a single tooth include:

  • Poorly fitting dentures or dental appliances
  • Viral infection
  • Fungal infection
  • Side effects of medication
  • Not getting enough nutrients
  • Sensitivity to mouthwash or toothpaste

How to Prevent Swollen Gums

Most causes of swollen gums are preventable by practicing good oral hygiene. Brush at least twice a day at a 45-degree angle, brushing away from your gums to remove debris at or below your gumline. Clean between your teeth with floss, interdental brushes, or water flossers at least once a day. Consider using other helpful products like antimicrobial mouthrinses and tongue scrapers. And be sure to see your dental professional for regular appointments. If your swollen gums last more than a few days or your condition concerns you, don't wait until your next appointment. Visit your dental professional right away for diagnosis and treatment. They'll be able to help you get your oral health back to a condition you can smile about.
