What are the factors to consider in deciding whether Botox will be a good solution for my gummy smile? (photo)

A diagnostic wax-up forms part of the Digital Smile Design (DSD) process. As the name suggests, Digital Smile Design begins with sketching out virtual two-dimensional improvements to the patient's smile based on photographs and videos. This is a more efficient way of trialing different tooth lengths and shapes since changes can be quickly made. Also because the photos integrate other parts of the face such as the lips and eyes, it is easier to figure out what changes are needed to harmonize the smile with the face.

The 2nd picture of your braces is not as clear as your pre-treatment photo so I will have to make some assumptions. In your pre-treatment photo, it appears there is some minor crowding of the upper teeth. Your lower teeth are not visible. The lower (front) teeth may have started to protrude and crowd forward along with the upper front teeth. I am not sure if you had any extractions done during your first or 2nd treatment. Some patients who have had extractions may feel that their tongue may be overcrowded or that their facial profile is becoming more flat.
