Besides paying attention to hygiene habits and brushing your teeth correctly, you should also go to the hospital for tooth bleaching. At present, there are several kinds of tooth bleach, and the effect is not bad, but most of them are expensive. Photocuring treatment is to cover the surface of teeth with a layer of resin similar to the color of teeth, and then use special light. This method is beautiful, convenient, fast, low cost and not very firm. Suggestion: It is an ideal method to make porcelain teeth, preferably porcelain veneer, if conditions permit. However, grinding some teeth is very expensive. If the teeth are unsanitary, you can go to the hospital to clean (wash your teeth), and the effect will be very good. Of course, it cannot replace brushing your teeth.
