What are the causes of a gummy smile?
There are several reasons why someone may have excessive gum display. The most common reasons are either a short or overactive upper lip which can be treated using facial injectables.
In other cases, however, the lips and teeth may be in the right position, but the gums are too thick, resulting in short teeth that look squarish. This is called ‘altered passive eruption’ and is due to the gums not moving upwards towards their natural position during growth and thereby covering some of the natural enamel underneath. There is often a genetic tendency to this condition.
Finally in some situations, people may have short teeth and a gummy smile due to wearing of the teeth because of teeth clenching or grinding. Each cause has a specific treatment and so it is important that your treating dentist performs a thorough analysis to determine the correct diagnosis and treatment for your condition.
