Is it Normal to Have Sore Teeth after Using Teeth Whitening Products?
As many people who have used teeth whitening products can attest, they can lead to some soreness and sensitivity in exchange for whiter teeth. It is completely normal to have sore teeth after using teeth whitening products. The soreness is temporary and should not last longer than a few days after the whitening process is completed. It is not entirely clear what causes this sensitivity in over two-thirds of people who use either at-home whitening methods or get professional whitening at the dentist. However, it is believed to occur when the peroxide used for bleaching comes into contact with the nerve tissue inside the tooth. Nearly all tooth whitening systems use peroxide as the active bleaching ingredient, which leads to temporarily sore teeth or sore gums.
