When teeth start to discolored and become yellow, some people go for treatment that will improve whiteness. Laser tooth whitening is one of the several teeth whitening techniques that are effective. Your dentist can help you choose which whitening method is best for you. The American Dental Association highly suggests that you check with your dentist before planning which whitening product to use. Dentists generally do a tooth whitening treatment in their office.
Laser whitening is more effective than other treatments of bleaching teeth. At-home bleaching methods usually have bleaching agent with a much lower strength than professionally applied tooth whitening agents. The effects of the in-office whitening is up to five years while over-the-counter treatment while over-the-counter methods can only have a span of six months to one year, explained by the University of Maryland Medical Center. Whitening toothpastes can only eliminate surface stains, unlike the bleaching methods which includes laser whitening it changes the basic color of the teeth.
As stated by Cleveland Clinic, the result of the laser teeth whitening can be seen even after just one session, though a number of sessions lasting 30 to 60 minutes each may be needed to achieve the whole effect. The products that you can see at you home, either over-the-counter or prescribed by your dentist takes longer to effect than the laser teeth whitening. At-home bleaching products recommended by your dentist and over-the-counter bleaching products generally need to be used every day for one or two hours or short-term for two to four weeks.
Often bleaching of teeth can result to softening or weakening of the teeth and gum line. The American Dental Association warns about the wrong use of the over-the-counter bleaching products because they can be too harsh and can injure the teeth with prolonged use. During laser whitening, a neutralizing gel or a rubber shield is set on the gums to care for gum sensitivity. No over-the-counter bleaching products have the ADA Seal of Acceptance, labelled by the ADA as ensuring a product has met ADA standards of safety and effectiveness. Harvard Medical Center also cautions that very little evidence exists supporting the enduring safety and usefulness of the teeth whitening.
