What color is a healthy tooth?

The surface of the tooth is covered with a layer of enamel, which is transparent or translucent, and the deep part is dentin, which is pale yellow. The color of healthy teeth is deep dentin, which is pale yellow through tooth enamel and is a sign of strong teeth.

The teeth of a few people are bright, white, porcelain, smooth, and reflective like porcelain, but less than this standard.

Two, the reason that the tooth turns yellow

(1) the causes of the teeth themselves

Some teeth are endogenous yellow teeth formed by the influence of certain primary colors. The pigmentation of this yellow tooth is not on the surface, but in the tooth tissue, so even after whitening, it becomes yellow again after a period of time.

(two) external factors influence

3. lemon + apple vinegar

Lemon in the nicotinic acid can effectively remove tartar, and Apple Cider Vinegar in vinegar gum can also make teeth white. I suggest you adjust the lemon juice and apple vinegar at 1:1, dip it on the cotton pad and gently wipe the surface of the tooth. It takes place every morning and evening, and it takes effect in a week!

4. mouthfuls of celery

The tooth care food recommended by French health expert Jean Gaag is celery. He thinks that when you chew your celery, it's a clean sweep of your teeth. The rich crude fiber in celery can effectively remove the food residue attached to the teeth and reduce pigmentation. In addition, the phosphorus in the celery, iron can also make teeth harder! But be sure to chew raw celery!

Chewing gum without sugar can increase saliva secretion, neutralize the acidity in the mouth, and prevent the teeth from tarnishing. Study on the University of Minnesota dental experts found that sugar free gum in xylitol can effectively inhibit the bacteria that cause cavities, so that you won't be long "scolecodont"! But in general, chewing gum for 7 minutes every day is enough, and more chewing will make the masseter muscle bigger!
