Normal teeth brushing activity no doubt reduces the density of yellowish coloring of teeth but not completely.
To get a pearly white smile there are many products and techniques available in the market.
Smile adds beauty to the personality but when you smile your teeth are displayed to all.
Some people take very good care of their teeth and they bear any cost to get white teeth.
But everyone cannot afford to visit dentist to have teeth whitening techniques, because they are very expensive.
To provide solution to this problem, over the counter teeth whitening products are available in the market, although some are more effective than others.
First is a tooth paste.
Most brands of toothpaste publicize whitening ingredients.
These toothpaste contain light abrasive material such as calcium carbonate or aluminum oxide that removes the debris from the teeth when applied and brings them to closer to their original look.
A next teeth whitening product is a thin plastic strips made with polyurethane and is coated on one side with hydrogen peroxide.
Next is a tray.
A plastic tray that fits over the teeth contains carbonate peroxide, but most of the time it doesn't get properly fitted to teeth.
Next is paint on, Colgate introduced first teeth whitening paint in 2002.
It requires applying peroxide individually applied to each tooth for 30 minutes and twice a day.
The product having more hydrogen peroxide amount is more effective but also more injurious to teeth having more side effects.
Teeth Whitening products can cause serious damage to gums, saliva and tooth enamel and also weaken the texture of teeth.
Teeth sensitivity to cold and hot is another side effect.
Every teeth whitening product is not suitable for everyone.
So go and ask your dentist before using any such type of products.
