Possible causes of a gummy smile are:
- 1. Over-developed elevation muscle of the upper lip
- 2. The upper lip and the gums are joined too closely
- 3. Excess gum tissue
- 4. Undersized teeth
- Gummy Smile treatment to loosen the join between the gums and the upper lip
- Gummy Smile myotomy operation
- Botox injections for the elevation muscle of the upper lip
- Surgical correction of the gums
- Cosmetic dentistry
Gummy Smile: Botox or MyotomyOften the elevation muscle is over-developed:Botox
An over-developed elevation muscle can be weakened with a few small injections of Botox in the elevation muscles of the upper lip (Elevator Labii Superioris Muscle). Botox ensures that the elevator muscle contracts less powerfully so that the upper lip isn't lifted as high when smiling. This means that your gums are less exposed when you smile. Your natural facial expressions remain the same.
The doctor gives you a few Botox injections just next to the nose. The amount of Botox units you need depends on the strength of the muscle. Generally 10 units of Botox are sufficient.
- The results of Botox injections last between 4 and 9 months, when the treatment can be repeated.
The plastic surgeon weakens the elevation muscle of the upper lip (myotomy) between the gums and the upper lip. This procedure is performed with a local anaesthetic and last about an hour. The incision is made in the mouth so that the scar is invisible.
Any swelling and bruising generally disappears within about two weeks. Sensory disturbance may occur. The movements of the corners of the mouth remain intact for a beautiful and natural smile.
- A myotomy operation gives permanent results.
- If this is the case then simply decreasing the join between the upper lip and gum tissue has the desired effect.
Sometimes the teeth look too small because they are surrounded by too much gum tissue. A gingivoplasty or gingivectomy treatment can offer a solution. If this is the case the cosmetic dentist will increase the surface of your teeth by correcting the gum tissue.
- Gingivoplasty = gum tissue correction = improving the appearance of the gum tissue around the teeth.
- Gingivectomy = removing excess gum tissue.
Sometimes the teeth are just too small compared to the gums. The cosmetic dentist can increase the surface of your teeth by:
- attatching venneers
- attaching crowns
