There is a difference between Fast and Cheap vs Professional treatment.
Why do Dentists & Professional Teeth Whitening Practitioners insist on a 1-hour appointment, whilst some feature ‘fast and cheap’ 10-15-minute treatments?
The reason is straightforward…
“It’s got to Reach it to Bleach it”
With all whitening systems it takes time for any bleaching agent to migrate it’s way safely through long resident staining trapped within the microscopic pores of your tooth Enamel before it can reach the Dentine below; (longer for badly stained teeth)
Dentine is the actual tooth ‘bone’ that gives your teeth their natural white colour.
This difference means
If the DENTINE is not reached, your teeth are not whitened as much as they could have been.
The difference is, any results can be short lived because you have only removed superficial staining from the enamel coating; hence, your money spent – wasted.
Another difference
Some ‘fast’ operators mix sodium chloride (salt) into their whitening gel.
As we all know, salt absorbs water, which means water is absorbed from the enamel immediately making them look much whiter than they actually are.
Unfortunately, within several hours your saliva rehydrates the enamel, and your money spent – wasted
