My teeth are extremely small and it makes me self-conscious. is there anything i can do to get this fixed?

Yes: Depending upon your exact condition, you could get crowns or veneers placed to have them look the right size. Some cases might benefit for orthodontic lengthening , or appropriate gum trimming ( gingivectomy ). Please consult a dentist to get your case specific advise.

Veneers: Small teeth can be made larger using a combination of gingival (gum) contouring and porcelain veneers. I would consult with your dentist to discuss your new smile design.
