My upper teeth are not visible when I talk. What can I do about it? (Photo)

My advice is that you consult an excellent cosmetic dentist to determine how you can be helped.  I suspect that veneers would do wonders for your smile, but would not fix it completely.  You will probably need a lip lift or other augmentations done by a plastic facial surgeon.  Good luck and I hope this helps.

based on what i see on your pictures, the size of the teeth, does not look big according to the smile, so thats why if we perform a smile design, and also with x rays,make a lip line analysis, we can work out the way that smile would look more natural and also we can change shape, size and colorprobably porcelain crowns , or veneers would be involved,with a waxing model this could be determined,but yes you have a solution.

Visibility of teeth when smiling can be from many factors, including little lip movement during expression, broken or worn teeth (among others).  Often, porcelain veneers allows an experienced and skilled dentist to control the size, shape and color of teeth.  These changes may be enough to accomplish your goals.

There are many reasons why teeth don't show when you smile ranging from simple short teeth, tooth wear to problems with how your face developed when you were young.  I would suggest you contact a dentist to have an evaluation done which will likely include a visit to an orthodontist.  Dentistry can do amazing things these days to help you with your problem.  I wish you luck finding a solution.
