Is a Gummy Smile Unhealthy?

Gum Contouring And Reshaping Columbus, OH

For many patients, a gummy smile is not a cause for concern. Though it may pose a cosmetic issue for more self-conscious individuals, gummy smiles usually do not bring complications. However, individuals whose smiles show too much gum should consult with a dentist to make sure that there are no major health concerns.

Possible causes of a gummy smile

In most cases, excessive gum tissue is purely hereditary. A combination of small teeth, a large jaw, and/or a short upper lip can contribute the gummy look of a smile. In rare cases, a large gumline can be the result of a condition known as hereditary gingival fibromatosis, which is a slow but progressive enlargement of the gum tissue. If left untreated, this condition can lead to speaking problems.

Hormones may also play a role in a progressively gummy smile. Hormonal imbalances caused by puberty or pregnancy can cause a increased blood flow to the gum tissue and change the way it maintains itself. If genetics and hormones are not the cause of a gummy smile; however, there are a few other causes a dentist may consider.

Altered tooth eruption

Though it sounds dramatic, tooth eruption is the natural process of new teeth pushing through the gumlines. For most people, the eruption of permanent molars occurs around age six, while the final molars — or “wisdom teeth” — erupt between the ages of 17 and 25. When something interferes with the growth of a tooth, dentists refer to the situation as “altered passive eruption.”

When APE occurs, only part of the tooth pushes through the gumline. This can cause the tooth to appear shorter than it actually is, thereby resulting in a gummy look. Though APE typically does not pose any health risks, it can hurt the appearance of one’s smile.

Poor dental hygiene

If a person’s gums suddenly appear larger than normal and the gums are red and swollen, the issue may be a lack of oral hygiene. When a person neglects dental hygiene, plaque can build up on the teeth. Eventually, the plaque can work its way down into the gumline, causing the gums to become inflamed and swollen. This occurrence is known as gum disease or gingivitis.

If left untreated, gingivitis can progress into periodontitis and, eventually, advanced periodontitis. Gum disease at any stage is dangerous, but periodontitis is especially so. In the advanced stages of the disease, the gums may begin to recede from the teeth and expose tooth roots. As the infection progresses, pockets may form in the gum tissue and fill with pus. It may also eat at the bone and result in tooth loss, among other complications.

Medication side effects

All prescription drugs come with a list of side effects. On many of those lists is “enlarged gums.” Types of prescription medications that often cause gummy smiles include those used to treat epilepsy, immunosuppressants, and medications used to treat heart disease.


In most cases, a gummy smile is not a cause for concern. However, it could be, which is why individuals should consult with a dentist right away if their smiles appear gummier than usual. If it is purely aesthetics that bother a person, a cosmetic dentist can provide appropriate treatment.
