We know that good health habits are very important to our health, and can also improve our own image, especially our teeth.

What causes tooth yellow

The first reason is that the toothbrush is too hard. In fact, if you want to thoroughly clean the teeth, the hard bristle toothbrush is definitely better than the soft bristle. However, the hard bristle toothbrush is more harmful to the teeth, often damaging the substances on the surface of the teeth, leading to pigmentation.

The second reason: with the growth of age and long-term use, teeth will gradually have a slight color change. Just like your own skin, it's white and smooth when you are young, and it will gradually darken when you are old. These are unavoidable, so if you are older friends, you don't need to care.

The third reason: there are also health habits. Some people don't pay attention to oral hygiene, and they don't brush their teeth in the morning and evening. There is a layer of food residue, soft dirt or dental calculus on the surface of the teeth. These yellow teeth are not caused by yellowing of the teeth themselves, but by not paying attention to oral hygiene. We should pay attention to brushing teeth at ordinary times.
