Bleaching Teeth Is A Simple Way To Restore Your Smile
Over a century ago, dentists found that hydrogen peroxide could be used for teeth bleaching. In 1917 a heat lamp and hydrogen peroxide were used as an effective teeth whitening method for dead teeth. So the thought of home teeth whitening isn’t a new idea afterall.
A few years later, dentists discovered that even teeth with live nerves could be lightened by soaking the tooth in a solution made of 30% hydrogen peroxide, which is ten times more powerful than the solution you use to clean cuts and scrapes. Because it was so potent, the dentist had to protect the patient’s mouth and other teeth by isolating the dark tooth with a special rubber dam.
