Every time I see the TV toothpaste ads are very envious, the model's teeth are in vain, and their teeth are black and yellow, usually do not dare to laugh, afraid of exposing black and yellow teeth are ridiculed.
Why do the teeth turn yellow?
1. Eat too much acidic diet
For dentists, they can easily remove stains from the coffee on their teeth, but the enamel damaged by the acid is not so well restored. Enamel is a thin layer that protects the teeth and is very susceptible to corrosion by acidic foods.
An acidic diet lowers the ph value of the saliva, so even if you swallow the acid, the acid will continue to damage your teeth!
2. Let the sugar stay in the mouth for too long Sugar for the mouth, is equal to two words: "tooth decay." If you drink or drink, it will be contained in your mouth and then swallowed, and the sugar branch remains on your teeth to make damage.
If you can, drink the drink can rinse the mouth, the sugar slightly rinse off, reduce the sugar to the teeth caused by damage.
3. Brush too many teeth
If you brush too many teeth, or brush too hard, may make your teeth exposed, this soft area can not withstand your extreme scrub, if you also use the wrong way of transverse brushing, the enamel is a physical wear, but also to weaken to the gums.
The correct way to brush your teeth should follow the gap between the vertical brush, power moderate, not excessive force.
4. Use of overly stimulating toothpaste On the market many advertised super effective whitening and so on the strong effect of toothpaste, but in fact some ingredients too stimulating, astringent mouth, but will cause adverse effects, corrosion of teeth.
Some Bai Qiang effect toothpaste will not only take away the stains of coffee, but also wear your teeth and gums.
5. Careless use of whitening patches A mouthful of white teeth is really very attractive, but the whitening patches in addition to the effect of different people, there may be some risk Oh! Experts say that if only the whitening patches are used in places with stains, there is no problem, but people often accidentally touch the patch to the gums.
Anything that can bring stains from
The tooth surface removes the thing, all has the ability to injure the gum!
Careless use of whitening patches may lead to gum tui, too often use will also excessive stimulation of the gums to make him damaged.
6. Nail Biting Biting the nails causes the gums to crack, causing the root to be exposed to pain, like a vampire's teeth.
The habit of biting your nails may also lead to a gap in the teeth and a scratching of the mouth.
7. Molar
If you get up and find symptoms of headaches or jaw aches, and the symptoms last all day, you might be a person who can grind your teeth in bed! Experts say molars can cause teeth to relax and ultimately endanger the bones around the teeth and gums.
Hard occlusion can lead to periodontal disease.
