The stain of smoking, the pigment of drinks, coffee and tea, etc. are yellow-gray on the teeth.
03, endogenous yellow teeth are affected by a certain element, pigment is not on the tooth surface but in the tooth tissue, there are two main types: dental fluorosis and tetracycline teeth.
Dental fluorosis is pigment in the enamel of the tooth surface, which is yellowish-brown plaque. In severe cases, there are uneven defects on the tooth surface. Generally, the incisors of the upper jaw are the most obvious, so it seriously affects the appearance.
Tetracycline teeth are caused by taking tetracycline drugs. Tetracycline molecules can combine with calcium in tooth tissues to form a very stable complex, which is deposited in tooth tissues and makes teeth colored. The whole teeth can be brown gray or brown yellow.
