has anybody had their teeth whiten by dentist?

How much does this procedure usually cost?

What method did your dentist use? I heard that laser can be use to whiten teeth.

I am thinking of getting my teeth whiten to look like George Clooney.

Is that all it takes to look like Clooney?

The ancient Romans used urine. I think that's mostly free

Whiteout might be cheaper!

My dentists take on tooth whitening was something along the lines of:

Whiter teeth don't indicate healthier teeth. Genetics and exposure to certain antibiotics can permanently stain teeth and these sorts of stains don't usually respond to bleaching. They generally require veneers.

Whitening usually weakens the enamel of teeth to some extent. If you have very strong teeth enamel it may not make a significant difference. If your enamel isn't the strongest due to wear, genetics of antibiotics exposure bleaching can dangerously weaken them.

Most OTC bleaching systems are too weak to show much benefit if not overused. Overuse can damage enamel and gums. Sometimes doing enough damage to cause the destruction or loss of teeth.

Many people who use OTC bleaching agents would be better off having their teeth professionally cleaned and then evaluated before they tried to bleach them with OTC products.

Mcleans whitening toothpaste will get them pearly and it's a lot cheaper than a dentists. Brush twice a day; don't rinse after and go as long as you can before eating or drinking. You'll see the difference after only a few days.
I've no affiliation with them; but am open to bribes! :-)
