The professionals at Xpert Dental focus on cosmetic dentistry, helping clients put their best face forward with blazingly bright smiles. Before faces are fitted for a mouth-enhancing shine, a comprehensive oral exam is given to make sure morsel manglers are in top condition, while giving gums and other oral tissues a thorough checkup ($150). After the thorough glancing, the dentist will take plastic molds of your teeth, which are then filled with Nite White whitening agent before insertion ($525). Like the superstitious socks of hockey players, the molds need to be worn for an hour a day for three or more days, depending on the dentist's recommendation and the desired level of whitening. In a few moons, patients are likely to notice a lightening of staining resultant from medicines; smoking; drinking wine, tea, and coffee; and normal darkening through wear and tear. As an added bonus, Groupon purchasers will receive 25% off any additional cosmetic dental work.
