Why do my teeth discolour?
Teeth discolour for a number of reasons. Very few people have bright white teeth, and our teeth can get more and more discoloured as we get older.
Teeth can also be stained by food and drinks such as tea, coffee and red wine. Smoking can also stain teeth.
‘Calculus’ or tartar can also affect the colour of your teeth. Some people may have staining under the surface, which can be caused by certain antibiotics or by tiny cracks in the teeth which can become stained as well.
