With nearly nine years of brightening experience, the professionals at XTreme Teeth Whitening understand the physical and psychological allure of brilliantly white teeth. Their light-accelerated whitening services brighten teeth in a scant 20 minutes, removing deep-set stains incurred from smoking or imbibing cups of coffee, wine, or soy sauce. The specially formulated whitening gel incurs neither sensitivity nor downtime, and a variety of products available for purchase can boost or extend results. Sessions can whiten smiles by up to eight shades, with results lasting for as long as two years with proper maintenance.
