The inside of the teeth is yellow, and the outside of the teeth is a little yellow. Stubborn, so brushing your teeth is not good. What should I do?

Brushing your teeth won't solve it. If there are dark spots on your teeth, you can solve them by washing your teeth frequently. As can be seen from the following figure, one-time tooth washing (generally 40 minutes) can completely remove the pigment from the cigarette stains, and the cost is about 100.

If the congenital teeth are evenly yellow, or even part of the edges are yellow, you can choose to do cold light whitening.

If it is dental fluorosis or tetracycline, it has a wide range of yellow staining and many stripes. Only porcelain crowns or resin veneers cover the color. Among them, after nearly 20 years of clinical experience, resin can be said to be an immediate and minimally invasive choice for whitening anterior teeth, with a wide range of applications.
