How much enamel is removed for veneers?
Typically about 0.3 to 0.7 millimeters from the front surface — roughly the thickness of a fingernail — and less or none in minimal-prep cases.
Veneer preparation is measured in fractions of a millimeter. The aim is to make just enough room for the ceramic so the tooth does not look bulky, while staying inside the enamel layer.
Why the number stays small
Bonding to enamel is stronger and more predictable than bonding to dentin, so dentists use depth-cut burs and mock-up guides to remove only what the design requires. Tooth position matters too: a rotated or protruding tooth may need more reduction on one surface, while an inward-tilted tooth may need almost none.
Enamel thickness varies by tooth and by individual, and removed enamel does not grow back, so the plan deserves a careful conversation. Ask your dentist to show the intended reduction on the mock-up before agreeing to preparation.
