A smile is a universal form of communication. Ever since mankind began, men and women have been obsessed with efforts to keep their teeth clean and bright to enhance their smiles. Some of the methods used were pretty crude by today’s standards but they laid the foundation for the modern approach to oral hygiene. Let’s take a brief look at the history of teeth whitening.
The first ever toothbrushes were used in 3000 BC. These comprised of small branches that were scuffed at one end. People rubbed them on their teeth to get rid of food particles and other debris. In the 1400s the first toothbrush was invented by the Chinese. These had bamboo handles and hog hair bristles. They caught the attention of European traders who introduced them to many cultures.
Louis Pasteur, a French bacteriologist, caused some alarm when he discovered germs. People learned that hog bristles could be responsible for oral infections. Scientists continued to search for a more sanitized substitute, but they were only successful in 1935 when nylon was discovered by Wallace Corothers.
A company called du Pont began marketing Dr West’s Miracle Tuft Toothbrush right across America. People were educated about the disadvantages of hog hair and informed about the advantages of nylon bristles. Unfortunately Dr West’s ‘miracle’ toothbrush was so hard that it damaged gums, so much so that dentists would not endorse them. It took du Pont almost another 20 years before producing the Park Avenue toothbrush with soft nylon.
The Squibb Company caused a dental revolution when it introduced the first electric toothbrush in 1961. The product received the stamp of approval from the American Dental Association and, over the coming years, the electric toothbrush became much improved. Today they are battery operated, cordless, and even sonic.
In 2000 BC the Egyptians were the first to start teeth whitening. They used a mixture of crushed pumice stone and wine vinegar which was rubbed onto the teeth using a chew stick. This might sound gross, but wait until you hear what the Romans did - they whitened their teeth with urine! Roman physicians were adamant that urine contained bleaching properties.
History shows that it wasn’t dentists who offered teeth whitening to the public. It was in fact barbers who were often asked to extract rotting teeth. After filing the teeth, they would apply a caustic acid as a whitener. It proved to be effective but, in the process, the enamel was destroyed.
Italian dentists were the first to realize that dental discolorations could be eliminated with fluoride. In the 1840s they recommended that children be allowed to suck sweetened lozenges containing fluoride. The benefits appeared to be so positive that fluoride was added to tap water, mouthwashes and toothpaste. This was discontinued years later when it was found that fluoride was the cause of discoloration of teeth in later life.
So here we are in the 21st Century and we are still trying to get the perfect smile with pearly white teeth. The American Academy of Cosmetic Dentistry reports a 300 percent increase in the number of whitening and bleaching procedures done over the past 5 years. These are much safer and more effective than the unsophisticated methods of yesteryear!
