Your Vernon Botox® Provider
An excessive amount of gum tissue when you smile can cause self-confidence issues and can prevent you from putting your best smile forward. The good news is that this condition may be treatable by your dentist.
What is a Gummy Smile?
A smile with more than two millimetres of exposed gum normally qualifies as a gummy smile. There can be many reasons for this type of smile, including:
- Short or hyperactive upper lip muscles, which results in the lifting of the lip upwards.
- Unusual or altered eruptions of the tooth or teeth during childhood
- The upper teeth are receding.
- Excessive growth of the upper jawbone
Treatment Options
Crown lengthening, botulinum toxin (BT) injections, and orthodontic treatment and surgery are the three main treatment options for a gummy smile. Your dentist will go over these options with you and come up with a treatment plan that may include one or more of them, depending on your specific needs.
Crown Lengthening
A crown lengthening procedure involves removing some of the gum tissue to expose more of the tooth. In another part of the procedure, the gum line will be sculpted to make it go higher up. This second stage, sculpting the gum line, will usually be done by a periodontist.
Whether just one part of the procedure or both will be needed depends on each individual patient. Your dental team will discuss your treatment process with you in great detail before getting started to ensure you understand what will happen.
Botulinum Toxin (BT) Injections
It's natural to think of botox injections as a treatment for wrinkles and fine lines, but they can be used for dental treatments as well.
Botox can be useful for gummy smile treatments as it can dull overactive upper lip muscles. Treatment normally involves very small injections over the course of three to six months. After this treatment is done, injections must be repeated every six months to a year.
Orthodontic Treatment or Surgery
If the gummy smile is being caused by excessive growth of the upper jaw bone, then orthodontic treatment and surgery may be required. An orthodontist might use a special appliance to push the teeth upward in order to correct the issue. If necessary, they may also work with a team of dental surgeons to surgically move the teeth upwards.
