Teeth whitening is known to cause teeth sensitivity. This is because whitening treatments use carbamide peroxide, which breaks down organic compounds staining your teeth but has the side-effect of burning your gum tissue and causing teeth sensitivity. To counter this, you can use Teeth Whitening Pre-Treatment and our Whitening Oral Care System. Both have been developed using natural ingredients known for their antioxidant properties that work to protect your teeth and mitigate feelings of sensitivity induced by whitening treatments.
