Laser teeth whitening has been praised by one healthcare practitioner, who said it is a great alternative to traditional methods.

Dr Timothy Kosinski, who practices dentistry in Michigan in the US, told ExpertClicks.com laser tools can lighten the teeth in a matter of minutes.

“This amazing technology is a very safe product with less sensitivity, a greatly reduced time for the procedure and highly effective whitening. And you can do individual teeth,” he explained.

Dr Kosinksi said laser teeth whitening can be performed in one appointment and the effects will be visible immediately, as well as lasting much longer than old methods.

The expert also called the procedure “far, far superior” to DIY teeth bleaching methods.

Last month, cosmetic dentistry expert Jennifer Jablow told Elle magazine teeth whitening can lighten teeth significantly, often in less than an hour.

She said patients may be able to achieve eight to ten shades lighter than their natural colour, depending on their teeth to start with.
