The increased in the number of cases obviously indicate that the popularity of teeth whitening is now soaring too, which means that people should really be very careful when undergoing such procedure.
In a recent study by a UK research firm, it has found out that one out of three adults is considering undergoing teeth whitening.
Teeth whitening is actually a simple process of bleaching a person’s teeth. The whitening products contain either of the two kinds of bleaches, hydrogen peroxide and carbamide peroxide, which break strains on the teeth into smaller pieces thereby making the color less concentrated and the teeth looking brighter, details Dental O So Gentle.
Teeth whitening products can be categorized into two major groups – one is the peroxide-containing bleaching agents and the other one are those called dentifrices or whitening toothpaste.
When a product bleaches the tooth, it works on removing the deep and surface stains on it. But there are also non-bleaching products which work by physical or chemical action to help remove surface stains on the teeth only.
While many would find it surprising, but it is actually possible to have stains inside the tooth called intrinsic stains. These can be caused by exposure to too much fluoride as a child while the teeth are developing as well as medications and possibly injury.
