Teeth whitening has become the most popular cosmetic procedure in the world. However, people should understand that it has its own limitations and drawbacks and is not for everyone. There are some people for whom teeth whitening is not advisable like pregnant women, women who are nursing children and people who are suffering from gum diseases. It is also not suitable for people who have cracked teeth or cavities in the area that they want to be whitened. One should also keep in mind that teeth whitening is only for natural teeth. Teeth whitening cannot be done on veneers, crowns, bondings and tooth-fillings.
How white your teeth appear after bleaching is subject to the existing tone of your teeth. According to the American Dental Association, people who have yellowish teeth have a better chance of getting their teeth bleached well compared to people with brownish teeth. For people with grayish teeth, there's some bad news. Their teeth are the least responsive when it comes to bleaching. However, there are exceptions to this observation. Some people with grayish teeth have had their teeth bleached beautifully.
If your teeth are discolored or stained due to the consumption of tea, coffee, wine or cola, then bleaching should work for you. A simple maintenance routine will help you retain those results for a long time. You can use the home-bleaching kits as per the instructions and keep your teeth shining white. A better way to drink colas is by making use of a straw. In case of intrinsic staining, caused by either genes or antibiotics, things are not so easy. Dentists say that they can lighten such stains to a considerable extent, but not as much as many patients would like.
Whitening Toothpastes
Whitening toothpastes are the most popular teeth whitening products available over the counter. The truth about whitening toothpastes is that they are as effective as they cost. Simply speaking, you get what you pay for.
What's available in the market?
There are many brands that have come out with lots of whitening toothpastes. Major brands are selling products like Aquafresh Whitening Toothpaste, Mentadent Advanced Whitening Formula and Colgate Total Plus Whitening Toothpaste. The companies do not make tall claims. Contrary to what other teeth whitening products claim, toothpaste companies are modest.
How do they work?
Almost all the whitening toothpastes work on the same principle. They use hydrogen peroxide in very small quantities to gently remove the stains developed due to consumption of things like tea, coffee, wine, etc. Aquafresh states that its product helps in weakening and removing the stains that build up on the teeth over a period of time. It is gentle enough to be used everyday and doesn't contain harsh bleaches, abrasives and peroxides.
Results
Many dentists believe that teeth whitening toothpastes are a complete waste of time and money. The general opinion is that they are as effective as any ordinary toothpaste in teeth whitening. All the good toothpastes clean the surface of the teeth and it is more than enough for keeping teeth stain free. Dentists believe that whitening toothpastes can help improve the color of your teeth to a very small extent. The change is very minute and in many cases not very noticeable. However, in some cases, people have experienced considerable improvement in their teeth color. Their teeth are so responsive that anything would work on them.
The whitening results obtained from teeth whitening toothpastes are almost negligible. The label of Mentadent states that it has a safe level of hydrogen peroxide along with fluoride and other cleansers. The level is good only for foaming and not whitening.
