This article explains why a home teeth whitening process is safe and affordable

Fact: Home teeth whitening whether a tray / syringe, Crest Whitening Strips or whitening pen method use exactly the same ingredients that your dentist would use.

These ingredients, either carbamide peroxide or hydrogen peroxide are enamel safe and they do not alter the structure of the tooth surface.

The main differenctial is the whitening tray that your dentist would make for you = time & the use of a "laser" light = time. Both of these equal COST. 

However recent studies have proven that the "light" process adds no value to the teeth whitening process - indeed it could lead to tooth dehydration (more tests are being undertaken).

What is more important is that the cost of producing a teeth whitening tray has not only come down but the quality of a DIY version at home is so good that. Whilst admittedly it is not quite as good as a dental version, it does a very good job a ensuring that the teeth whitenig gel fits nicely around all your teeth.

The introduction of the very first Crest Whitestrips back in 2001 revolutionised the American dental market. Controlled amounts of hydrogen peroxide were now delivered onto the teeth is a simple and easy method

The cost of an average teeth whitening gel syringe kit is not expensive with most kits depending on strength range between £25 - £50, with a good thermo shrink teeth whitening tray for around £15.

Crest Whitening Strips range from £34 - £55 depending on the kit and strength

So for a grand total of under £100 you can complete a great oral care program for a fraction of the cost it used to be.

Again teeth whitening is now no longer just for the rich and famous. It really just depends on what method you prefer and suits your lifestyle, gel / syringe & tray or crest white strips or a whitening pen.
