The right side of my mouth doesn't go up as much as the left when smiling. I'd like to know how I'm able to fix this. (Photo)

Your lip asymmetry could be due to previous injection by dermatologist, age, not pulling the muscle up as the other side. It is a possibility to do lip exercises for some improvement. By injecting botox by an experienced dermatologist, it can help the problem temporarily but not permanently. You must be examined with a cosmetic dentist to find out the root cause of the problem, and possibly by other specialists.

Your lip asymmetry can be corrected with Botox, reducing and relaxing the upper lip that goes to high. Actually you have great teeth and a great smile even though the smile is not even. If it really bothers you, I would make sure there are no underlying systemic causes before treating with Botox. 

yr issue is not with teeth but it is with lips, u have good set of teeth and consonant smile. yr smile is uneven , is because of hyper activity of one side muscle. there r two ways to correct it. u can go for botox , but u have to  take botox every 4 month and second option is physio therapy - he will guide for some muscle exercises. visit physio therapist who is specialist in oro facial musculature.

Hi:Unfortunately without a clinical exam it is difficult to give you accurate exam. Normally, the solution for similar situations has been to do Botox to relax the muscle on the side that the lip goes too high.Best,Dr. Maddahi

Asymmetric teeth visibility due to lip tonicity issues could be corrected with botox. It is always  good to find out why there is such an issue and whether it is an indicator of systemic disease.
