Can veneers stain or discolor?

Veneers are highly resistant to stains, but they are not completely immune to discoloration. Porcelain veneers are less likely to stain than composite resin veneers, as porcelain is a non-porous material that resists staining from foods, drinks, and smoking. However, over time, the bonding material used to attach the veneers to your teeth may become discolored, especially if exposed to staining substances. To keep your veneers looking their best, it is important to practice good oral hygiene, avoid consuming excessive amounts of stain-causing foods and beverages, and attend regular dental check-ups. Your dentist may also recommend avoiding smoking, as it can contribute to discoloration.
