Teeth whitening is the procedure that gives the teeth more color than the current color, without removing any part of the tooth enamel layer.
Causes of tooth color change:
- As with skin color, the colors of teeth vary among humans depending on their genes. It is normal to darken the teeth color with age.
- Teeth can be dyed due to certain foods and beverages such as tea and coffee. Smoking also causes pigmentation of the teeth. Acidic food and drinks, such as carbonated water and fruit juices, cause yellowing of the teeth, because they erode the outer layer of the tooth (the port), resulting in the appearance of the deeper layer (yellow ivory).
- Pigmentation may also arise from the treatment of certain antibiotics during the period of the formation of teeth such as Tetracycline Tetracycline. Minocycline can also cause pigmentation in adult teeth.
Teeth whitening decision:
The doctor determines the person’s need for teeth whitening, after he has examined his teeth thoroughly, and the doctor determines the type of bleach that can be done.
