Tooth whitening has been used in dentistry for over 100 years and in all that time there haven’t been any significant safety issues. Tooth whitening by a dental professional is safe and effective. Legally only dental professionals are able to provide tooth whitening and you can be sure that at our surgery only safe whitening gels are applied to your teeth. There have been cases where people who have no formal dental training such as beauticians, hair salons etc have been using unsafe gels which strip the enamel from your teeth.
