I want my teeth to show when I smile, but all you can see is the very tip of them. What can I do to help this? (photos)

I would consider seeing a good orthodontist and getting a treatment plan that includes braces.  This will give you a smile that shows more tooth structure and aligns your upper and lower jaws. Good luck.

I would suggest you visit a dentist that focuses on cosmetic dentistry or an orthodontist. Those are two great places to start since they are both familiar with facial and smile aesthetics and can offer suggestions for meeting your goals. It may be best to start with the cosmetic dentist first since they can help the orthodontist understand any planned cosmetic or restorative work. Based on the photos it appears that you have great lip shape so improving the position of your teeth and brightening them up can help you become more confident in your smile. Invisalign or traditional braces would be an excellent first step. By leveling, aligning, and improving your bite you can eliminate many aesthetic issues and provide a much better foundation in which to build any cosmetic work you may elect to have done. Often patients come into our office asking for veneers and we find we can accomplish their aesthetic goals with more cost effective options such as Invisalign and whitening. The best option for you depends on your unique starting point, time constraints, the specific outcome you are looking to accomplish, your expectations, and the shade (color) you would ultimately wish to obtain. We find once those questions are answered the best option becomes clear. We wish you the best of luck and hope you obtain a smile you can be proud to show off!
