I have lost a lot of enamel in my teeth so i want to get caps or veneers. how do i choose which to get?

Choose the dentist: First choose the dentist who comes highly recommend and whom you both trust and respect. He\she will discuss pros and cons of each and which one is recommended in your particular case. This is something that cannot be properly addressed on this type of forum. One needs to personally examine you, have x-rays and study models prior to recommendations.

See your dentist: for comprehensive examination, digital cosmetic imaging and treatment options. It is a matter of preference for you and your dentist.

Dental exam: It depends on which teeth, how much enamel has been lost, and the reason why. Hard to answer your question without this information. Please ask your dentist at your examination.
