Discolouration of the teeth is part and parcel of the ageing process. Just like every other body part, enamel of the tooth also wears down, giving the teeth a dull appearance. Discolouration is also a side effect of long term use of smoking, incessant consumption of coffee or tea. Other reasons for discolouration include the use of medication, especially antibiotics, genetic makeup etc. Teeth whitening and dental veneers/crowns are an ideal solution to this problem of discoloured or dull looking teeth.
