Teeth or tooth whitening is one of the most common dental procedures today. Generally speaking, the positive effects of teeth whitening from a dentist can last for up to five years depending on the overall dental hygiene and exposure to tooth discoloration agents of the particular patient. Characteristic candidates for tooth whitening are those patients that are experiencing teeth that: have been darkened from normal wear and tear, stained from coffee, tea or dark soda, or discolored from cigarette smoking. Teeth that have become discolored yellow, brown, or orange can, in most cases, be remedied with teeth whitening procedures. We have also provided exceptional results for patients with stained teeth cause by fluorosis or tetracycline, although the results are not nearly as dramatic.
Generally, bleaching is successful in at least 90 percent of patients, though it may not be an option for everyone. Consider tooth bleaching if your teeth are darkened from age, coffee, tea or smoking. Teeth darkened with the color of yellow, brown or orange respond better to lightening. Other types of gray stains caused by fluorosis, smoking or tetracycline are lightened, but results are not as dramatic. If you have very sensitive teeth, periodontal disease, or teeth with worn enamel, your dentist may discourage bleaching.
First, the dentist will determine whether you are a candidate for tooth bleaching and what type of bleaching system would provide the best results. At Dental Esthetic Solutions we use in-office bleaching system, at home bleaching system or both systems depending how white you want your teeth. The fist appointment, the dentist or dental assistant will make impressions of your teeth to fabricate a mouthguard appliance for you. The mouthguard is custom made for your. The mouthguard is so thin that you should even be able to talk and work while wearing it. Along with the mouthguard, you'll receive the bleaching materials. The mouthguard is lightweight so that it can be worn comfortably while you are awake or sleeping. We will demonstrate how to apply the whitening agent to the reservoir and how to position the tray in the mouth.
Lightness will last depending on your personal habits such as smoking and drinking coffee and tea. At this point you may choose to get a touch up. This procedure may not be as costly because you can probably still use the same mouthguard. The retreatment time also is much shorter than the The 'active ingredient' in the product is usually hydrogen peroxide or carbamide
Several studies during the past five years have proven bleaching to be safe and effective. The American Dental Association has granted its seal of approval to some tooth bleaching products. Some patients may experience slight gum irritation or tooth sensitivity, which will resolve when the treatment ends.
No one can really predict how much lighter your teeth will become. Every case is different. Typically, there is a two-shade improvement as seen on a dentist's shade guide. The success rate depends upon the type of stain involved and your compliance. Bleaching can only provide a shift in color from gray to a lighter shade of gray, for example. Bleaching does not lighten artificial materials such as resins, silicants, or porcelains.
