Teeth whitening or teeth bleaching is the procedure of whitening the shade of your teeth. Teeth whitening is desired when teeth get yellowed over time due to several reasons and is effectively done by changing the color of the surface or intrinsic layer of the tooth enameling. The intrinsic layer of the tooth is the one that is responsible for the visible layer on the teeth, which is called the dentin. It is in this layer that the stains are formed, and these stains tend to fade away over a period of time if you maintain a good oral hygiene regime. However, if you have been using tobacco products for a long time, or if you are an alcoholic, or if you consume a lot of sugary and acidic foods, chances are bright yellow teeth will continue to haunt you for a long time to come.
Some of the common tooth staining include strep throat, gum disease, caries, and even kidney stones. These stains do not occur due to the presence of any harmful substance on the teeth but due to the reaction of the natural chemicals produced by the body, mostly peroxide, after the food is consumed. Some of the more common ingredients that cause teeth whitening reactions include hydrogen peroxide, carbamide peroxide, chlorine bleach, hydrogen peroxide, sodium hydroxide, calcium bicarbonate, sodium fluoride, magnesium fluoride, sodium azide, aluminum chloride, and zinc.
Some of the best teeth whitening options include Professional Peroxide, Bleaching Kits, and DIY Kits, and these provide safe and convenient ways of whitening the shade of your teeth within a few short weeks. However, you need to consult your dentist before choosing any of these options, as they may cause severe damage to your gums, teeth and even the nerves of your mouth. There are a lot of teeth whitening products available in the market today, and they include Whitening strips, gels, brush on applicators, brush on gels and combo packs. Most of these products deliver similar results; however there are some products that may be better than the rest.
Whiteners may take a while for visible results, but this should not worry you too much as the results will last a long time. Whitener strips can be used twice daily, with each strip being applied for a specific period of time, say for two weeks. Whitening gels can also be used twice a day, but it is important for your dentist to note that these gels are only best if you visit him regularly. DIY kits contain hydrogen peroxide, calcium bicarbonate, sodium hydroxide and carbamide peroxide, which are all known to have bleaching properties. If you are using a combo pack, you should keep in mind that your teeth may react to the combination of ingredients, so talk to your dentist first.
Whitening toothpastes are used to brighten your smile and bring back the whitish tone that was lost due to smoking, coffee, tea and even the fluorescent lights in your office. Teeth Whitening kits are usually used to treat mild to moderate staining, but they too contain bleach agents. While some products claim to be bleaching agents, it is important to note that whiteners do not contain bleach; bleaches contain ammonia and are known to cause damage to your enamel, while whiteners do not contain any chemicals. Thus, teeth whitening can be safely used by everyone, but you should still get professional advice before starting a bleaching regime.
Teeth Whitening does have its advantages and disadvantages and you need to consider them carefully. First of all, there is the cost involved in getting these procedures done, with the more sophisticated home kits costing more than a hundred dollars. You cannot afford to invest that much money on a procedure that may not achieve the dramatic results you want. Also, because some tooth staining is temporary (for example, coffee stain), the procedure may not be effective after several months of use. Finally, while these home kits work well, you will not get the same dramatic results with bleaching, but the brighter smile you want will only last as long as it takes for the stain to fade away.
