LET'S MAKE THE TEETH WHITER!


Why do our teeth have stains and discolorations?I can give you many reasons and here are some of them:
First we have the so called extrinsic staining  factors like: age, tobacco,red wine, coffee, cola, tea or deeply-colored beverages and food.Superficial extrinsic stains are minor and can be removed with brushing and prophylactic dental cleaning. Stubborn extrinsic stains can be removed with more involved efforts, like teeth bleaching.
 Other types of stains can be caused by antibiotics ,trauma and even too much fluoride.These are the intrinsic stains  those that form on the interior of teeth.Today, thanks to cosmetic dentistry even deep-set intrinsic stains can be removed .
 As a good start it is advised that before using any whitening procedure you should first be evaluated by your dentist to determine which application and program are best for you.
A supervised bleaching procedure that is performed in office and at home have become among the most popular treatment options.
When the procedure is performed entirely in the office, significant color change in a short period of time is the major benefit .In the dental office, before-and-after tooth color is typically measured with shade guides.
While whitening can occasionally lighten tooth color by nine or more shades, most of those who bleach their teeth are likely to see a change of two to seven shades.
 This protocol involves the carefully controlled use of a relatively high-concentration peroxide gel, applied to the teeth by the  trained dentist after the gums have been protected with a paint-on rubber dam and a special light may be used to enhance the action of the agent.. Generally, the peroxide remains on the teeth for several 15 to 20 minute intervals that add up to an hour (at most). Those with particularly stubborn staining may be advised to return for one or more additional bleaching sessions, or may be asked to continue with a home-use whitening system.
 But in other cases, the dentist gets the procedure started during an office visit and then gives you what you need to complete it at home.
Many dentists are of the opinion that professionally dispensed take-home whitening kits can produce the best results over the long haul. Take-home kits incorporate an easy-to-use slower acting carbamide peroxide, which breaks down into hydrogen peroxide. Carbamide peroxide has about a third of the strength of hydrogen peroxide. This means that a 15 percent solution of carbamide peroxide is the rough equivalent of a five percent solution of hydrogen peroxide.

The procedures at home consists of placing the  bleaching solution, in a tray or “night guard” that has been custom fitted for your mouth by your dentist. The bleaching solution is then worn throughout the night. Your dentist should advise you on the appropriate type of application. and on the length of time needed to whiten your teeth, based on the severity of tooth discoloration and your specific needs.

Teeth whitening results are subjective, varying considerably from person to person. Many are immediately delighted with their outcome, while others may be disappointed. Before you embark on any whitening treatment, ask your dentist for a realistic idea of the results you are likely to achieve and how long it should take to achieve them. Expectations play a major role in teeth whitening Also notice that if you have a tooth color filling, the filling will stay yellow and will not be affected when tooth whitener is applied.

Side effects to tooth bleaching? Well, patients have experienced uncomfortable short-term side effects when having teeth bleached like increased temperature sensitivity in the teeth. Another side effect when night guards are used is that it often cause gum irritation.
The general health risks of bleaching systems are minimal as far as your body is concerned.

Pregnant or nursing women are advised to avoid teeth whitening. The potential impact of swallowed bleach on the fetus or baby is not yet known

P.S A smile costs nothing but buys everything !
