Before you take teeth whitening into account in discolored teeth that dentures cannot be brightened and teeth and gums must be healthy as well as a "professional teeth cleaning" must be completed before.
With age, the teeth have an ever darker color. This is a physiological process, which is mainly due to the abrasion. But this can also be the case at a young age through bruxism or abrasion. The tooth colors are innate in humans, so the teeth have a different white color.
Tints of the teeth are innate and can vary significantly from person to person, but the teeth become darker with age.
By nature, dark teeth can be completely healthy and white teeth can have hidden tooth damage, but for white teeth, there are several teeth whitening methods on the market. With the "bleaching" more and more people make their teeth bright white teeth. Whitening means whitening teeth in relation to the color in the beginning. When whitening the teeth colors are brightened so that the teeth can regain a natural white, but for each teeth whitening is a professional tooth cleaning first necessary first. The prerequisite for whitening is oral health, which is mainly understood the dental health which makes a dental check or a check at the required dentist. Dental restorations must always be renewed before teeth whitening because dentures cannot be brightened, which is why carious teeth and leaking dental fillings must be remediated before each bleaching session. It should also be clarified before the teeth whitening,
whether it is an internal tooth discoloration or tooth interior as visible tooth discoloration because internal tooth discoloration can only be treated by the dentist. Internal tooth discolorations cannot be removed by a cosmetic tooth cleaning or a tooth whitening at home. Interior stain, such as a dead tooth that has a greyish to black discoloration, requires the dentist to open the affected tooth or pulp cavity from the former tooth nerve tissue and introduce the bleach into the pulp cavity. In whitening, stubborn discolorations, which can not be removed by professional teeth cleaning, and teeth that are naturally darker, lighten the skin. For this, the dentist uses hydrogen peroxide, which bleaches the teeth, as is usually the case with home bleaching with the bleaching bar.
Different reasons for tooth discoloration due to pigmentation (color retention): Food and stimulants such as tobacco, tea, coffee, red wine, etc. Congenital damage to the enamel Taking certain antibiotics (tetracyclines) during tooth development Dead tooth pulp or root canal treatment tooth fluorosis due to overdosage of fluorides (fluoridation of the teeth)
Methods of tooth whitening The bleaching of teeth is one of the most popular methods of teeth whitening for beautiful teeth.
For teeth whitening, preparations containing hydrogen peroxide (H2O2) are generally used because they can penetrate the tooth and release oxygen radicals there. They are able to change dyes in the tooth chemically so that they no longer appear in color on the teeth. Teeth whitening agents should be of neutral pH so that the teeth are not roughened, or that tooth erosions can occur and thus promote a renewed tooth discoloration. With every tooth whitening, it can lead to a hypersensitivity of the tooth necks and thus to aching tooth necks, which disappears however after a few days if the tooth nerve is no longer irritated. By whitening the teeth, which does not harm the teeth when the whitening is done correctly, one can regain a bright tooth white.
For tooth whitening different methods are used: Brightening with custom-made splints (Home Bleaching) In the case of home bleaching, a precisely fitting plastic splint, which covers the teeth of the entire row of teeth in the form of a dental arch, is deep-drawn and cut out by the dental technician or prosthodontist after the impression of the teeth and model production in dental technology. To brighten up the teeth, the bleaching tray is filled with peroxide-containing whitening gel so that brown teeth turn white again. Depending on the concentration, the patient usually wears this dental splint at between one and eight hours during the night. For age discoloration or age-related tooth discoloration often suffice about seven bleaching treatments, with the stubborn stain of the teeth by tetracyclines usually 15 or more bleaching treatments with the bleaching tray are necessary.
Brightening by direct application (power bleaching) By whitening the power whitening which can also be called "in-office whitening," a direct application of higher concentrated preparation is used. The bleaching treatment is therefore usually on the patient chair at the dentist. The gingiva is covered with a rubber latex-like coating as a "rubber dam" during preparation, and the Gingiva protector is coated on a composite basis with highly concentrated office bleaching gels to protect the gums. The higher the concentration of active ingredient in the lightening gel, the quicker and more effective the lightening result, but also the higher the risk that bleaching will damage the gums due to the caustic effect of the gel. The gum is therefore covered with a special light-curing plastic so that it does not come into contact with the whitening gel when whitening the teeth. The brightener is brought by the dentist directly on the whitened teeth and can act there. With plasma lamps, the whitening gel can be heated to increase the effect. Because by light irradiation with "whitening lamps" the effect is intensified. This is only possible with bleaching gels, the chemical by the action of short-wave UV light is activated, and after 15-30 minutes, the gel can be removed, or the gel is sucked off with the suction cannula and the teeth rinsed with water. If the teeth whitening is not sufficient, the power bleaching can be repeated. Normally, for a first whitening, one to two bleaching treatments are needed to achieve a lasting result. When the "in-office bleaching" is finished, the gum is removed from the cover, and usually, a fluoride gel applied to the teeth as fluoride prophylaxis. Teeth whitening through deposits in the tooth (walking bleach technique) Teeth whitening through dentition is called the walking bleach technique where a single, devitalized tooth brightens, and we know it is dead, and we call it a root canal treated tooth or dead tooth. In the walking bleach technique, the tooth is not lightened from the outside but bleached from the inside. When there is an intrinsic tooth discoloration, and the tooth appears gray. The tooth crown is opened, and a suitable bleaching agent is introduced into the tooth cavity, which used to fill out the pulp. If a root canal treatment has been necessary, the tooth is already drilled out so that teeth can be whitened. The tooth is closed again provisionally and left the brightener for one or more days in the tooth. Teeth whitening by the walking bleach technique is visible immediately after the end of the bleaching treatment, and the effect lasts for a very long time.
