When choosing a clinic in which to undergo cosmetic dentistry, it can be hard to know where to go, so speaking to people you know who have had treatment can be helpful, industry commentator has suggested.
Sebastian Guthery, writing on Article Maniac, pointed out that it is essential to find a reliable surgery and one way of doing this is to research the clinics.
He advised speaking to local dentists who will be able to refer patients and to check the background of potential surgeons.
But an essential resource can be those who have actually had operations done.
Mr Guthery explained: "If you have relatives, close friends and colleagues who have undergone teeth whitening, they can be your best sources."
However, if a dental professional does not have the right qualifications, he stated that it is never a good idea to allow them to perform any surgery, as it can be dangerous if they use the wrong materials.
Recently, the Poughkeepsie Journal advised that before people go through with cosmetic dentistry the surgeon should make sure the patient understands the operation.
