The Zoom! light activated whitening gel's active ingredient is Hydrogen Peroxide. As the Hydrogen Peroxide is broken down, oxygen enters the enamel and dentin, bleaching colored substances while the structure of the tooth is unchanged. The Zoom! light aids in activating the hydrogen peroxide and helps it penetrate the surface of the tooth. A study has shown that use of the Zoom! lamp increases the effectiveness of the Zoom! gel by 33% or more, giving an average improvement of eight shades. The patented BriteSmile whitening treatment consists of a lamp filtered to emit light in the blue-green region of the spectrum (approximately 400-500 nanometers) and a patented delivery device, which illuminates all smile teeth at once. The BriteSmile light is used in combination with a patented peroxide gel, which has been optimized to obtain a maximal whitening effect and to ensure patient safety. The patented chemistry consists of a 15% hydrogen peroxide gel buffered at an approximately neutral pH that is compatible with tooth enamel. The gel also contains other ingredients such as glycerin and highly purified water to prevent tooth dehydration and to further ensure safety. The gel also contains a patented photo-initiator, which assists in chromophore destruction at the tooth's surface.

What is an Impacted Tooth?A tooth becomes impacted when there is a lack of space in the dental arch and its growth and eruption are prevented by overlying gum, bone or another tooth. How Serious is an Impacted Tooth?Impacted teeth can be painful and lead to infection.They may also crowd or damage adjacent teeth or roots.More serious problems may occur if the sac surrounding the impacted tooth becomes filled with fluid and enlarges to form a cyst. As the cyst grows it may hollow out the jaw and permanently damage adjacent teeth, the surrounding bone and nerves. Rarely, if a cyst is not treated, a tumor may develop from its walls and a more serious surgical procedure may be required to remove it.Despite the considerable concern regarding impacted third molars, a recent study sponsored by the American Association of  Oral and Maxillofacial Surgery Foundation finds that third molars which have broken through the tissue and erupted into the mouth in a normal, upright position may be as prone to disease as those third molars that remain impacted.
