After getting veneers, you may feel confident about your new white, straight smile. However, over time, you may notice that your veneers are becoming discoloured. Why does this happen, and can you whiten veneers?
How Veneers Become Discoloured
Veneers are usually made of either porcelain or composite resin. The Canadian Dental Association explains that porcelain veneers don't become stained or discoloured, but the same isn't true for composite resin veneers.
Composite resin doesn't stain as easily as your natural tooth enamel, but it can still become discoloured over time. Surface stains may develop after prolonged exposure to highly pigmented drinks like tea, coffee or red wine. Smokers may also develop yellow or brown surface stains on their composite resin veneers due to nicotine.
