One of the most inexpensive and easily obtainable tooth whitening systems is the whitening strip. These strips were introduced into the market in 2001.
These whitening strips have the whitener 16% carbamide peroxide pre applied by on them. Some dentists feel that the strips are good as the dose delivered is consistent and it limits the user's exposure to gel, whereas when gel trays are used the amount of gel used can vary between each use.

There's something about a big smile. Especially a big smile that shows beautiful white teeth. A bright white smile says "healthy", and admit it, people with beautiful white teeth somehow even look happier. A whiter smile can make a person more confident and outgoing in social situations. Unfortunately most of us don't have the whitest smile that we could.

Like many other industries including fashion, beauty, hair and now teeth whitening the trends are mainly driven by the latest look and with glossy magazines and TV makeover programmes making a lucrative industry out of it has driven people to desire the latest look to improve their image and make them feel better about themselves and increase their self confidence.
