Every day our teeth are stained by a variety of foods and drinks that may not be removable by scaling or polishing treatments alone (depending on the type of stain).  As a result, professional teeth whitening/bleaching is an excellent solution to remove outer stains, bleach the tooth from the inside, or enhance the tooth's initial structure.  Professional teeth whitening solutions use stronger materials than anything available to the public and can improve your digestive health as well.  While professional teeth whitening can improve your oral health and strengthen your enamel, DIY whitening methods can do the exact opposite.
