Restoration of a natural tooth colouration can be achieved by removing surface staining caused by substances such as tobacco, tea, coffee, and red wine. This process is commonly referred to as laser bleaching and involves the use of light energy in order to speed up the bleaching process. Different types of light energy can be used in this procedure, the most common being halogen, LED, or plasma arc.

It is possible to trace the practice of teeth whitening as far back as 3000 B.C. People at this time would use chew sticks to remove debris from their teeth. Meanwhile, the Egyptians concocted a paste from pumice stone and wine vinegar to create a teeth whitening solution.

Since ancient times, white teeth were seen as a sign of beauty and wealth. The Romans used ammonia in urine to lighten their teeth, and in the 17th century, acids were used to whiten them.

Unfortunately, this led to tooth decay. However, in the early 1800s, fluoride was discovered and incorporated into food and water, leading to fewer cavities.

But the use of too much fluoride caused the staining of teeth. In the 1980s, bleaching with peroxide became popular to whiten teeth. It happened quite an by accident as peroxide was originally used as an oral antiseptic gel to treat the gums.

A dental clinic realized that the side effect was that it whitened teeth. Today, one of the best methods of whitening teeth is a high concentration of hydrogen peroxide combined with laser LED light. Were you looking for the best teeth whitening in Toronto GTA?
