When used as directed, whitening strips are generally safe and should not damage your teeth. However, they can cause temporary tooth sensitivity and gum irritation, particularly if used too frequently or left on for too long.
Whitening strips work by applying a thin layer of peroxide-based gel onto the teeth, which helps to break down stains and discoloration on the surface of the enamel. This process can cause temporary sensitivity because the peroxide can penetrate the enamel and reach the nerve endings in the teeth.
To minimize the risk of sensitivity and gum irritation, it’s important to follow the instructions carefully and not leave the strips on for longer than recommended. It’s also a good idea to use a toothpaste designed for sensitive teeth and avoid consuming foods and drinks that are known to cause staining, such as coffee, tea, and red wine.
Overall, while there is a risk of temporary sensitivity and gum irritation with the use of whitening strips, they are generally considered safe when used as directed. If you have any concerns about using whitening strips, it’s always a good idea to consult with your dentist or dental professional.
