Not enough tooth show when smiling, is a lip lift my only option?

In agreement with other responders, this question is personal, every situation must be evaluated based on multiple individual considerations, and therefore only general information can be provided here rather than recommendations about what is best for your specific situation.  There are always alternatives, but what you're starting with and your goals, your desired look, will determine which of those alternatives are best for you.  Don't be scared of lip lift.  They usually work out very well when planned and executed by skilled and experienced surgeons.  Of course, problems, complications, and revisions are sometimes encountered, and must be managed when they do.  That's still no cause for fear, but should stimulate you to continue researching to find proper professional help.

Dear BettyW1945,
a photo would help a lot. The best option for you would be to visit a board-certified plastic surgeon and get a formal examination. After an examination, the surgeon should be able to tell you whether you are a good candidate for a lip lift.Daniel Barrett, MD, MHA, MS
