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.
