See a dentist: For professional teeth whitening without laser, followed by home whitening system with custom trays for the long term effect.

Note: there is no evidence based dentistry or scientific research to support that any "laser" have an effect on teeth whitening.

Two options: Providing that you maintain good oral hygiene , floss, brush, etc. There are many otc teeth whitening systems today, or you can have them professionally whitened at your dentist office
