  2. 2. What Is Teeth Whitening?There are two main methods of bleaching. The first involves applying a high concentration ofoxidising agent for a short period of time, which is the so-called office bleach. This produces quickresults but risks chemical burns to the soft tissues. Therefore, most in-office bleaching procedures use a light-cured protective layer that is carefully painted on the gums and papilla (the tips of the gums between theteeth). The bleaching agent is either carbamide peroxide, which breaks down in the mouth to form hydrogenperoxide, or hydrogen peroxide itself. The bleaching gel typically contains up to 35% hydrogen peroxideequivalent.The alternative method involves using a thin mouthguard or strip to hold a low concentration ofoxidising agent next to the teeth for as long as several hours a day for a period of 5 to 14 days. This isknown as take-home or over-the-counter bleaching. This is a slower process but has fewer risks to thesoft tissues. The bleaching agent is typically less than 10% hydrogen peroxide equivalent.A typical course of bleaching can produce dramatic improvements in the cosmetic appearance of moststained teeth; however, some stains do not respond to bleaching. Tetracycline staining may requireprolonged bleaching, as it takes longer for the bleach to reach the dentine layer. White-spotdecalcifications may also be highlighted and become more noticeable.Recently, efforts have been made to accelerate the bleaching process by the use of light. Studies haveshown varying results as to the efficacy of light-activated bleaching.Side effects of tooth bleaching include chemical burns (if a high-concentration oxidizing agentcontacts unprotected tissues, which may bleach or discolor mucous membranes), sensitive teeth, andover bleaching (known in the profession as "fridge-door teeth"). Rebound, or teeth losing the bleachedeffect and darkening, is also an issue, with some studies showing the rebound effect over 30 days. Arecent study by Kugel et al has shown that as much as 4 shades of lightness can be lost over 30 dayswith light-activated/office bleaching.
