How much of the tooth is shaved for a veneer?
A conventional laminate veneer removes roughly 0.3 to 0.7 millimeters from the front surface — about the thickness of a fingernail.
Porcelain laminate veneers are among the more conservative ceramic restorations. Preparation usually stays within the enamel layer, trimming a fraction of a millimeter from the front of the tooth so the ceramic shell does not look bulky.
What decides the depth
The target shade and the starting position of the tooth both matter. A dark tooth needs slightly thicker ceramic to mask the color, and a tooth that leans outward needs more reduction than one sitting inward, so the figure is a range rather than a single number.
Enamel thickness itself varies between individuals and even between teeth in the same mouth. A dentist can review your enamel on scans during a consultation and estimate how much reduction your case would involve before anything is done.
