A new teeth whitening treatment from the US has shown good results.
A new teeth whitening treatment has been developed in the US which has been found to be highly effective. 
Dr Jan Linhart of New York has achieved an almost 100 per cent success rate when using a new laser teeth whitening treatment called PearlinBrite and boasts patients can achieve a nine to ten shades improvement in teeth colour after just one session.
The system uses a laser to activate peroxides in a gel which is applied to the teeth.
Dr Linhart noted: “Because PearlinBrite is so precise, we are able to minimize exposure of the gums and avoid issues of gum tissue sensitivity while getting great results.”
Elsewhere, Hollywood socialite Kim Kardashian recently announced on Twitter that she had undergone a teeth whitening treatment.
The reality TV star posted pictures of herself having the procedure carried out, with the caption: “At the dentist for a good teeth cleaning! This is serious!”
