Hi, I’m getting married next year and would like to have a whiter smile. My teeth aren’t too badly stained, but I’d like to be a few shades lighter. Local salons in my area have various deals – i.e.£75 for laser treatment, whereas my dentist is closer to £400 for a tray that sits in your mouth and takes longer. Obviously, I want the treatment to be safe and not damage my teeth, but £75 is far more appealing when I have a wedding to save up for. Is there any way I can research a salon and any questions I should ask, especially regarding the chemicals used for the belaching agents and the qualifications of the staff? Also on a slightly different note, my fiance has calcium deposits in his front teeth and wants to know if whitening would remedy that or make it more obvious? Many Thanks.
