My bottom teeth show more when I smile I really want to fix my smile but don't want to waste money. (Photo)

Hi:Without better photos and clinical exam it is difficult to give you accurate advice.  The main issue seems to be that the upper teeth may not be at the proper length.Best,Dr. Maddahi

I agree with Dr. Maddahi.  We need more info, like x-rays and pictures of how your upper teeth match your lower teeth.  Has your smile always been this way?  When did you first notice this?  Do you clench/grind your teeth? Has any dentist suggest you get a mouthguard to prevent grinding/clenching?  Did you have braces?  This info would be incredibly helpful.  Can your smile be changed?  Absolutely.  

Hard to tell from your photo. I would guess veneers to lengthen your top teeth would solve the problem, but would have to see more photos.

It is difficult to evaluate your case based on one photo. I would recommend a detailed examination with an experienced cosmetic dentist.
