Teeth can be made whiter with strips and gels, whitening toothpastes, whitening rinses and tray-based whiteners, according to WebMD. Tray-based whitening systems entail using a tray that resembles a mouth guard to apply a bleaching agent to the teeth. The tray is typically worn several hours each day for several weeks or longer. The time taken to whiten teeth is contingent on the amount of tooth discoloration and the patent's preferred level of whitening.

WebMD adds that in-office bleaching offers the quickest method to whiten the teeth. The whitening solution is applied using a laser or special light. Significant results are seen in one treatment session. Typically appointments last 30 to 60 minutes, and two to three sessions are scheduled for optimum results.

Hydrated silica, which is a mild abrasive, and polyvinylpyrrolidone, or PVP, a substance that prevents new stains from forming, are both used in whitening toothpastes, according to DDSSmiles.com. Baking soda is also used in toothpastes or alone to whiten a lackluster smile.
