You might be wondering: do whitening strips damage teeth? When used as directed, whitening strips are considered to be safe. However, the American Dental Association (ADA) notes that there is a risk of minor side effects.
The most common side effect when using whitening strips – or any product that contains bleaching agents – is tooth sensitivity. You might notice a sharp pain when your teeth are exposed to hot or cold foods or drinks, when you breathe in cold air, or when your teeth are touched.
Over-the-counter whitening strips contain low concentrations of bleaching agents, so any sensitivity you experience should be minor and will resolve in a few days. You might find it helpful to use a toothpaste for sensitive teeth in the meantime.
Another potential side effect is gum irritation from the bleach in the whitening strips. You can reduce this risk by applying the strips very carefully so that they only sit over your teeth, avoiding contact with your gum tissue. If your gums start to feel sore, remove the strips immediately and rinse your mouth with water.
The internet is awash with home remedies and viral whitening products, but these can range from ineffective to dangerous. It’s always best to buy whitening strips that have been tested and verified for effectiveness and safety. For best results, always follow the directions on the packaging.
