Dr Mervyn Druian is one of the founding members and current secretary of the British Dental Bleaching Society (BDBS).
This is a group of dentists who are lobbying for stricter guidelines, so only dental professionals can perform a tooth whitening treatment.
Find out about teeth whitening.
Our advice to you is always go to a dental professional if you are going to have your teeth whitened.
To our knowledge, no evidence has ever been documented where a tooth whitening (from a dental professional) has damaged teeth.
Recent research of the Nu Radiance Duet whitening system has shown that there are no changes to the tooth surface from this treatment.
We have come across no literature showing any structural changes or irreversible damage to the tooth structure.
Dental bleaching has been undertaken safely for the past 60 years.
