There is no doubt about the fact that a flawless set of teeth not only makes you look better, but gives you immense self-confidence and creates a great visual impact on the people you interact with. Teeth whitening is a treatment which whitens the stained or discoloured teeth. This treatment is one of the most popular cosmetic dental procedures, as it totally transforms one’s look. But the patient requires a step-wise process for the same. The treatment is available at affordable cost. When it comes to getting a quick and great result, it is worth giving a try.
The most common reasons for tooth decolouration are chewing tobacco, smoking cigarettes, drinking too much of dark coloured liquids like tea, coffee, red wine, etc. Moreover, lack of good care of teeth also leads to discolouration of teeth as the enamel gets thinner and dentine becomes darker. The outer layer of a tooth is called the enamel. A thin coating called ‘pellicle’ is formed on the enamel gradually, and picks up stains. The pores contained by the enamel also helps in holding stains. The stains can be of two types; Extrinsic and Intrinsic. The stains which are inside the tooth are intrinsic which can be caused either by excessive exposure to fluoride during childhood or consumption of tetracycline antibiotics by mothers during the second half of their pregnancy or by a child of 8 or more years of age. The other type of stains is called extrinsic which affects the outer surface of the tooth.
Before the treatment gets started, it is required to get the cavities treated as the process of whitening may affect the inner parts of the tooth while treating decayed part. The patients need to understand that the tooth whitening treatment will make the teeth sensitive in the cases of tooth decay or receding gums. Afterwards, the real treatment gets started. Mainly there are two types of procedures to whiten the teeth – In-office and DIY (Do it Yourself) home bleach. Further, the in-office treatment can be of two types. The most common out of them is Vital Whitening which is performed on teeth having live nerves. A gel containing hydrogen peroxide or carbamide peroxide, is applied directly over the surface. Later, a concentrated whitening agent is applied which triggers the gel and instantly leaches the coloured substance. And the other procedure is Non-vital Whitening which is performed on teeth that have had root-canal treatment and no longer have a live nerve.
The myths that teeth whitening treatment causes harm to the enamel, makes teeth sensitive for a long-period of time, is a painful process, and could lead to mouth cancer, are all completely wrong. This treatment is not recommended for lactating/pregnant women and children under 13 years of age.
