I understand everybody wants whiter teeth.
Howerver teeth are not as bright white as you may see on TV. IMO some are just too white, un-naturally white.
 
Teeth whitening is very unpredictable. It may or may not work.
 
There are some products that will make teeth whiter, some products do not...no matter what the advertisements claim.
 
What does not work..
1. whitening toothpaste
2. whitening floss
3. whitening mouth wash
4. many OTC whitening agents
 
What works
1. WhiteStrips work very well
2. In dental office whitening
 
Remember the old say...'If it sounds to good to be true it usually is'.  It's amazing how many 'old says' are still true today.
 
A "dental cleaning' will remove surface stains only, it will not removes the deeper staining in teeth that has occured over the years.  To remove those deeper stains a patient needs to use a peroxide whitening product.
