Is defined as, a smile that shows too much of the upper gum and teeth when you smile or laugh. It is usually caused by strong muscles elevating the upper lip, a thin upper lip or a combination of the two.
There are many causes for a Gummy Smile including:
- Hyperactive muscle that elevates upper lip
- Thin upper lip that exposes more of the upper gum
- Genetics – which can be responsible for a hyperactive or short lip
- Bone structure
- Problems with the teeth or size of the teeth
- Gums – they could be long or enlarged
Apart from Gummy Smile Orthodontic treatment, there are a few simple injectable methods to correct a gummy smile, including botulinumtoxinA injections and lip fillers. One or both of these methods may be used, depending on each individual patient.
