Don't use the first glass of water in the tap.
The first glass of water in the faucet has been left all night, and it is not ruled out that there will be heavy metals exceeding the standard. It is not recommended to gargle or brush your teeth.
The whiter the teeth, the better. The healthiest tooth color is not pure white. The higher the degree of calcification, the more transparent the enamel, and the color of the tooth itself will come out, showing a light yellow color.
Changing the toothbrush regularly also has a long life. Use at least twice a day, and change the toothbrush regularly for three months.
Choose soft hair for toothbrush.
Choosing a soft toothbrush is not easy to stimulate gums and damage enamel. Soft-bristle toothbrushes can also go deep into cleaning blind spots such as teeth.
Don't get wet when brushing your teeth
Toothpaste is not cleaned by foam, but by the friction between the ingredients in the toothpaste and the tooth toothbrush. Some toothpastes have anti-allergic function, and the effective ingredients will be released quickly after contact with water. Toothpaste with high fluoride content is not suitable for children under 6 years old. Because the child's hands-on ability is poor, the gargling technique has not been fully mastered. If you brush your teeth with adult toothpaste, you will inevitably swallow toothpaste with high fluorine content by mistake.
Don't brush your teeth immediately after meals.
There will be a lot of food residue on the tooth surface after meals, which will soften the enamel on the tooth surface. After a long time, teeth will become soft and brittle. If your teeth are gone, you should brush your teeth, not just the surface of your teeth, but the whole mouth. Although the teeth have fallen out, the mucosa, gums, alveoli and other tissues in the mouth are still there.
If you don't brush your teeth, bacteria in your mouth can easily cause oral problems.
