My 6 front teeth were prepped for Porcelain Veneers 2 days ago. I have an appointment in 2 days to have the Veneers placed. I have been avoiding using the front teeth for eating and have been wearing a night guard (they are a touch cold and air sensitive) Tonight I was LIGHTLY brushing my teeth a chunk (about 15% of the tooth) broke off from the rear left side of my front center left tooth. I have no additional pain, but want to know how this will affect my veneer placement in a few days.
