A lot of the price difference between cheap veneers and expensive veneers comes down to the dentist’s skill and experience. Veneers are not taught in dental school and they are extremely tricky to get right. They take a high level of technical skill and an artistic eye that not every dentist has.
We like to think of it like this: if you want to have your portrait painted, you could do a Google search for “painters near me.” You’d find a lot of painters. However, some of them would specialize in painting houses, some in landscapes, and some in portraits. You could hire a house painter or landscape artist to paint your portrait, and it might be cheaper, but the results won’t look nearly as good as they would have if you hired the portrait painter. Of course, with veneers, the art in question will shape your smile for the next 20-30 years! With those kinds of stakes, investing in yourself is definitely worth the extra expense.
