Some people are born with yellow teeth, or wear out the enamel on the teeth as they age, and acidic foods can corrode the teeth, leaving the enamel lost to turn them yellow. Smoking, tea or coffee will also accelerate the yellowing of your teeth.
The following introduces several methods of whitening teeth, each has its advantages and disadvantages.
1. Whitening toothpaste
General whitening toothpaste contains calcium carbonate, hydrogen peroxide, which helps remove tea, coffee, curry and other coloring ingredients. In addition, if a thin layer of whitening toothpaste is applied on the teeth before brushing, so that the whitening substance stays on the surface of the teeth for 5 minutes, it can also effectively prevent pigmentation. However, the effect of whitening toothpaste is only temporary, to be used forever to help.
2. White tooth paste
The whitening tooth paste contains urea peroxide or hydrogen peroxide (hydrogen peroxide), which oxidizes the surface of the teeth, and then breaks down the pigment substances to make the teeth look white and bright. However, the whitening teeth paste can take one to two weeks to work, and it is not easy to fully cover the tooth range, making the whitening effect uneven.
3. Home teeth whitening gel
Peramine peroxide in whitening gel is the most commonly used ingredient in bleaching technology. You only need to sleep with a customized dental braces full of whitening gel, remove them and clean them when you get up. But whitening effects usually take a week to work, and bleaching substances can make teeth sensitive and soft.
4. Soda power
Mix 3 tablespoons of Soda power and several drops of lemon juice for daily brushing, or directly use a small amount of soda powder and toothpaste. Because the soda powder contains sodium bicarbonate, it has a slight corrosive effect and helps to remove the dirt from the surface of the teeth. However, when using, pay attention to the weight of combing powder and lemon juice, excessive and too dense use will wear teeth.
5. Wash your mouth with coconut oil
Tooth oil gargle method has been popular in European and American countries for a long time, as long as you get up with coconut oil gargle for 10-15 minutes, and then the daily brushing action can be done.
6.Blu-ray floating teeth
Dentists coat the surface of the teeth with hydrogen peroxide, which use blue light or laser to redo it. REDOX is done by using hydrogen peroxide to break the pigment molecules on the surface of the teeth until they are invisible to the naked eye. In only 20-30 minutes, the teeth can whiten by 8-10 color scales and last for more than half a year.
