Stains Mild Tetracycline stains
Discoloration Caused by tobacco, coffee, tea or highly colored food
Yellowing Natural aging
Factors & Causes
Tooth color is in most cases an inherited trait, however, tooth color mainly depends upon the condition of the teeth, dental health and lifestyle.
Various factors could lead to tooth darkening or discoloration. The most common factor are : the intake of staining fluids, such as cola, tea, coffee or wine; tobacco; cigarette smoking and time.
Change in temperature of foods and drinks allow the teeth to expand and contract, thus enabling the penetration of stains onto the teeth.
Foods that are slightly acidic open up the pores of the enamel and allow stains to move in. Teeth darken as we age because the staining factors act upon the teeth for a longer period of time.
There are also internal causes such as tetracycline stains, fluorosis, injury, dental work and, of course, the aging process. Depending upon the severity of staining, bleaching will lighten the darkest areas but may not totally remedy the condition. |
