Can teeth whitening damage enamel if done repeatedly?

Can teeth whitening damage enamel if done repeatedly?

When done correctly and under professional guidance, teeth whitening does not damage enamel, even if repeated over time. Whitening works by penetrating the enamel and breaking down stains, but it does not remove or thin the enamel itself. However, repeated whitening can sometimes cause temporary sensitivity or gum irritation. Problems are more likely if whitening is done too frequently, with very high-strength products, or without proper supervision. For this reason, it’s important to follow professional advice on how often to whiten and to use appropriate products. Done properly, whitening is considered a safe and conservative treatment for improving the colour of your teeth.
