Tres White! These are usually given to you by the dentist, but you can purchase them on Amazon or other places on line.. They are strong and you don't have to leave them in for long and the results are incredible. Some people have good luck with over the counter strips such as crest, listerine and all those other strips, but I did not. I needed somthing that had a tray that could mold to my mouth. The Tres White whitened my teeth more than any of those other over the counter ones worked. Once i got the white i wanted (which was using less than one package) i maintained my white teeth by using crest whitening toothpaste. and if i felt my teeth were starting to stain (after over a year) then i put in another tray and it got me back to my whitest color again.
