It is very common for people require a fresh bright smile and are willing to paying for their, whiter teeth. However the question is does teeth whitening work and safe is it? Here are the answers to common questions about teeth whitening.
What is teeth whitening?
Teeth whitening are a process of bleaching your teeth to make them lighter. Teeth whitening cannot make your teeth brilliant white, but it can lighten the existing colour by several shades.
Who can perform teeth whitening?
Teeth whitening is a form of dentistry and should only be performed by a dentist or another regulated dental professional, such as a dental hygienist or dental therapist, on the prescription of a dentist.
Some beauty salons offer teeth whitening, but this is illegal if there's no dental professional present, and it may put your oral health at risk.
You can also buy DIY home teeth whitening kits but these may also carry risks if not purchased from your dentist as home teeth whitening kits should not have more then 6% bleaching agent (Hydrogen Peroxide) but some of the fake kits are being sold with levels at 11% to 15% which can cause serious harm.
What happens during teeth whitening at the dentist?
If you have teeth whitening you will need to make several visits to the dental surgery over a couple of months.
The dentist will take an impression of your teeth to make a mouthguard and will instruct you how to use it with a bleaching gel. Then, using your mouthguard at home, you regularly apply the gel for a specified period of time over two to four weeks. Some whitening gels can be left on for up to eight hours at a time, which shortens the treatment period to one week.
Another type of teeth whitening system that a dentist can provide is called laser whitening, which is also known as power whitening. This is where a bleaching product is painted onto your teeth and then a light or laser is shone on them to activate the whitening. Laser whitening takes about an hour.
