Teeth whitening products are flooding the market today. Understanding what each product is and what is can do is confusing at times. But the fact remains, yellow teeth are not attractive. Teeth become yellow by smoking, eating and drinking certain foods.
Professional teeth whitening by a dentist is considered to be the most effective method. The dentist does raise fear in people; typically trepidation started during childhood and has stayed with people into adulthood. According to recent studies dentists will not recommend products but they all agree on one basic fact, using over the counter products will whiten teeth if used properly.
As technology advances and regulations are relaxed many of the over counter products contain the same ingredients as the professional whitening systems. The ingredients in professional systems are hydrogen peroxide and carbamide which are now used in home teeth whitening kits.
Each whitening system varies from person to person, it all depends on the condition of teeth and how
often the teeth whitening system is used.
Home whitening kit trays work by fitting over your teeth. These need to be fitted properly or the solution will not bond with your teeth, which will reduce the whitening effect. Most of these tray systems need to be worn for many hours. Some have reported sensitivity to their gums from the use of this product.
