How do you protect your newly bleached, bonded, crowned or veneered teeth from getting stained? Any teeth, even cosmetically treated ones can be stained by tobacco and certain foods and drinks. Veneers and crowns are generally more resistant to stain than bleached or bonded teeth. To avoid stains, avoid tobacco products, coffee, tea, red wine and heavily colored foods. Use a straw when feasible to avoid direct contact of potentially staining liquids to your teeth. Visit our clinic to consult with our team about stain prevention methods.
