Had eMax veneers fitted 2 months ago. I recently noticed a light brown spot that's not on the outside of the veneer? (photo)

Dental labs, custom color the veneers with extrinsic surface stains to make them look more natural. Emax veneers are very durable, and from your picture no fracture is evident. See your dentist to check your emax veneers. It is possible that due to acidic saliva some of the extrinsic stains change color.

Emax has become quite a popular material these past few years. It is much harder and stronger than porcelain which us usually a good thing. The brown spot is a part of the veneer and depending upon how the color was created on the veneer removal of the spot could range from very simple to needing to remake the veneer. Speak with your dentist to see how the color was processed and what he recommends.
