A 'gummy' smile happens, as the name suggests, when more of your gums show than your teeth when you smile. It's very common and can be treated by a periodontist. Some people describe the condition as having 'short' teeth – although it's more likely your teeth are standard length, just covered by excess gum tissue. There are other factors that can cause gummy smiles, too, and the first thing your periodontist will do is establish the cause of your gummy smile.
The treatment will depend on the cause. For excessive gum tissue and worn teeth, crown lengthening is a common treatment. This involves removing and reshaping excess gum tissue and bone to expose more of your natural teeth. This can be performed on one tooth or several teeth, and is also sometimes performed before restorative treatment such as crowns. In some cases, laser treatment is available to remove excess gum tissue.
If your teeth are very worn-down or naturally short, your periodontist may recommend dental veneers. These could be made of porcelain or a composite, tooth-coloured material, and will restore your teeth to their natural length.
Orthodontic treatment such as invisible braces can be used for some genetic conditions affecting the jaw, while surgery can correct hyperactive lip elevator muscles. In some cases, Botox can also be used to control these muscles, although this treatment would require repeating every few months.
