If you are looking to beautify your smile, porcelain veneers and cosmetic bonding allow you to cover up tooth defects and spaces in just one visit. Invisalign invisible braces provide concealed straightening. Most dentists also offer tooth-colored fillings and crowns. Inlays are similar to dental fillings in the sense that they are used to cover teeth that were decayed or damaged. The difference is that dental fillings are molded on the spot, while inlays are created first in a lab, fitted onto your teeth, and then finally bonded.
