What is tooth discoloration and types of tooth discoloration?
Tooth discoloration is a change in the color of the teeth that might involve the entire surface of the tooth or look like dark lines or spots on the surface of the teeth. There are two type of tooth discolorations:
1. Intrinsic discoloration: Intrinsic stains develop due to changes that develop inside the tooth and affect the dentine (second layer of the tooth-beneath the enamel). They can be caused by factors such as tooth injuries, aging, health conditions and due to certain medications such as tetracycline.
2. Extrinsic discoloration: Extrinsic stains affect the outer layer of the tooth or the enamel. They can be caused by certain factors such as stained food items such as tea, coffee, red wine, cola, tobacco products and excessive use of anti-bacterial plaque inhibiting mouthwashes.
