If you’ve invested in veneers, your stunning smile can last for 10 to 15 years before needing to be replaced. Although the thin shells cover the front surfaces of your teeth, that doesn’t mean you can stop brushing or flossing. While your veneers aren’t vulnerable to cavities, your underlying teeth are still at risk of tooth decay, which can cause your new smile to fail. Thankfully, maintaining your veneers is easy to get the most from your investment.
