Continued use of abrasive toothpaste can remove tooth enamel and cause gum recession, exposing the tooth’s root surface and leading to painful tooth wear.Instead, Berg recommends using a multi-purpose fluoride toothpaste daily. “People who have tooth-colored fillings or restorations (including crowns and veneers) in their ‘smile zone’ should limit the whitening they do.” That’s because crowns, veneers, and fillings are made of porcelain or composite materials which, unlike enamel, does not whiten and may look darker in comparison to natural teeth after whitening. Better to be safe and talk to your dentist first. Unfortunately, the whitening trays sold in stores and online are usually one-size-fits-all, which can make teeth whitening unsafe and unpredictable. So, to avoid unpleasant repercussions of using ill-fitting whitening trays, best to see a professional.
