Teeth whitening methods are used to improve their colour and tone of teeth using a variety of methods. It is necessary to counteract the gradual staining and darkening of teeth due to a variety of reasons including smoking, ageing and drinking coffee.
Teeth whitening can be performed in many ways. Some of the most common methods are:
All toothpastes aim to make the teeth whiter and cleaner but there are certain toothpastes which specialise in the whitening area.
These toothpastes contain special substances that whiten the tooth by polishing its surface.
These toothpastes do not contain bleaching agents in high quantities and aim to gradually improve the shade of your teeth.
Whitening rinses are mouthwashes which contain chemicals that help whiten the teeth and improve their colour.
They don't just freshen the breath and reduce the risk of gum diseases but also contain bleaching agents which whiten the surface of the teeth.
In general, the results from using whitening rinses take longer to take effect, usually in around three months or so.
Laser or LED teeth whitening is a highly effective method which can only be done at a cosmetic salon which contains the necessary equipment.
A peroxide gel is applied to the teeth and is then exposed to UV or LED light to facilitate faster action of the compound on the tooth surface.
There can be some side effects associated with tooth whitening procedures. For instance, many people complain that they experience increased tooth sensitivity after going through a tooth whitening procedure. This happens because the peroxide in the substance used for whitening is able to pass through the enamel and reaches the nerves of the tooth. This causes irritation and leads to increased sensitivity.
Teeth whitening, sadly, is not permanent and will start to fade after a span of few months. One can delay the process to a time period of little over a year by minimising their teeth's exposure to foods and beverages which cause staining.
