A. Some people have a very high smile line- and this shows when you smile and laugh. If you are deeply unhappy about this, then there are certain treatments that can be done to make your smile appear more attractive- but this all depends on the severity of your smile line. I would suggest that you see a cosmetic dentist to see what can be done. Many clinics offer free consultations. They will discuss all of your options and achievable results with you. It may be that there will be an improvement, but not as big an improvement as you would like. It is not something to go into lightly, and you will need to explore all avenues before embaring on any treatment.
