Can I inject Botox to my gum to close spaces in between my teeth? (Photo)

Botox injected into the gums will not close any spaces between the teeth.  You should consult with a dentist to discuss treatment options to improve the space between your teeth.  

Botox can be used for a variety of issues that are mediated by muscle tissue - but straightening the teeth or allowing them to move is not an effect of Botox treatment. I am curious to learn how much Botox this dentist intended to use in order to achieve this effect.

While I think Botox is a miracle drug, Botox will not fix a dental problem. Botox generally works on the muscle and  therefore will not work to bring your teeth together. You likely need to see a dentist who can either put an implant or use braces to align your teeth. Botox, however, does work to fix a gummy smile. 

Thank you for your question. Botox is used to relax and soften wrinkles. Since there are no muscles in the gums it will not help close the spaces between the teeth. Please consult with a dentist for recommendations. 

A gummy smile can indeed be improved with Botox injections ; this requires expert treatment, so make sure to see a highly trained cosmetic physician such as a dermatologist.
