dude, the cheapest and BEST stuff is Ultra bright!!! Its the best, but it requires consistency...if you use something else for like a week, yellowness starts coming back. I love that tooth-paste!

If you drink many of soft drink that could cause it, i used to drink WAY too much diet coke but i halted and my teeth aren't so bad now. It stains them so i don't think brushing gets stains off or you can try whitening items like gel or tape but make certainly it doesn't undermine your teeth or you'll be off even worse (in the long run).

stop drinking staining beverages or food like coffee, soda, tea and etc..... if you cant stop then drink you coffee or staining drink using a straw. then beginning bleaching your teeth.

OTC toothpaste will not whiten heavy coffee, tea or intrinsic stains (stains from within your teeth). Toothpaste are made with very mild whitening ingredients since we use it daily. You may want to consider Crest whitestripes. They seem to an effective OTC whitener out on the market. Otherwise, confer with your dentist or dental hygienist for sturdier RX strength whiteners like Zoom, Opalescence...

Maybe your teeth only appear to be more 'yellow' because of the artificially too white teeth that we are getting used to seeing now.



Ultra Brite is good. Their slogan used to be "Whiter looking teeth are just a tube away".



I bear in mind the teeth whitening agent that was on the market in the '70's and '80's.

It was determined that too much usage deteriorates your teeth in the long run.

Maybe it's the same now.

I've seen people with too white teeth and the edges of their teeth are transparent.
