How to make your teeth white
The ancient Romans used urine as bleach to whiten their teeth. It was the ammonia in the urine that contributed to a bright smile.
The Greeks of old times applied strange mixtures and chemicals to their teeth which they extracted from leaves.
During the 17th century people used to go to their barber to whiten their teeth. The barber filed the teeth and rubbed nitric acid to them. Unfortunately this practice, left people with a few or no teeth at all because they decayed.
The Europeans of the Renaissance applied bleach to their teeth. They had whiter teeth for a limited period but as time passed their enamel started to wear away resulting in tooth decay.
In the early 19th century, fluoride was discovered in order to maintain healthy teeth. On the other hand an excessive use of fluoride caused teeth staining.
Bleachorexia: A Serious Disorder Which Destroys Your Teeth
Bleachorexia may sound harmless, but it's a very serious disorder. People who feel like their teeth are never white enough and bleach their teeth over and over are said to have bleachorexia. A dentist coined the term a few years ago when he started noticing patients coming in over and over for bleaching treatments whose teeth were in really bad shape as a result of the over bleaching. When a person has bleachorexia they usually use home bleaching kits several times a week and see the dentist for more in-depth bleaching on a regular basis. But the overexposure to harsh bleaching gels and additives in home bleaching kits can destroy teeth.
Whether you use a DIY kit or have teeth whitening done at the dentist if you use a product or have a treatment done that doesn't use natural elements to whiten teeth you could get hurt. Many products that aren't naturally based use harsh chemicals that can destroy the surface of your teeth, ruin the enamel of the tooth, or even cause nasty chemical burns on the gums. Chemical burns on the gums can take weeks to heal and they are very painful.
