Teeth Whitening Procedures
The first thing that people notice about you is your smile and sometimes you may want to make your teeth whiter or brighter with various teeth whitening. It is teeth whitening procedures that restores the natural color of teeth as well as bleaching them. There are many reasons that teeth may become discolored, and there are professional procedures as well as home procedures that may help to whiten your teeth.
Adult teeth are darker that the deciduous teeth that children have. Teeth become darker when their mineral structure changes, and as enamel becomes less porous. Bacterial pigments, various dark-colored foods and beverages, tobacco, acidic foods, and some antibiotic medications contribute to the staining of teeth, as well as microscopic cracks in the enamel from age, and use.
Intristic stains are found within the structure of the teeth that may be caused by aging or trauma while extrinsic stains are on the surface of the teeth only. It is the microscopic cracks on the enamel that fills the teeth with debris and stains.
In-Office Bleaching – Cosmetic dentists specialize in teeth whitening, and may use washes, gels, laser light, or a combination of procedures. Teeth will generally be examined and cleaned initially, and tooth color will be discussed, using a shade chart. The doctor paint the teeth with hardening resin in order to protect it from bleaching as well as inseting a cheek retractor.The hardening gel is rinsed off after 30 minutes and another gel applied. Intense laser light may also be used to activate or enhance bleaching gels. The cost on an average is $650 per treatment.
Looking On The Bright Side of Products
Over-The-Counter Or Dentist Supplied Whiteners – These whiteners are used at home, and can be toothpaste, whitening strips, whitening trays or bleaching pens, and usually contain baking soda, carbamide peroxide, or hydrogen peroxide. Most over-the-counter whitening toothpaste include minor abrasives, which scrub stains from the enamel. The products described above are not as effective as in office procedures unless they are used repeatedly for longer periods.
Why People Think Wellness Are A Good Idea
Certain vegetables and fruits act as natural bleaching agents that help in removing stains. Baking soda may also be used in brushing, as a mild abrasive to scrub stains from the outer enamel.
The primary risk to your teeth from whitening is damage to the enamel. A damaged tooth enamel will expose the teeth and then cause increased sensitivity.
You should not have your teeth whitened if you are pregnant or nursing, due to the risk of ingesting peroxide. While undertaking the teeth whitening procedure, it is good to have realistic expectations.
