The main cause of yellow teeth is the wear and tear or staining of the enamel, the outer layer of the teeth. Here are 5 situations that lead to this:
Diet and drinks: Excessive consumption of coffee, tea, and soda stains teeth. The ‘tannin’ component in these causes the teeth to lose their white color.
Tobacco use: Nicotine and tar cause severe yellow or brown stains on the teeth in smokers and those who use tobacco products.
Poor hygiene: Due to not brushing your teeth properly, ‘plaque’ accumulates on the teeth. This can cause the natural color of the teeth to fade over time.
Age: As you age, the outer white enamel layer of the teeth becomes thinner. The yellow ‘dentin’ underneath is exposed, giving the teeth a yellow color.
Genetic factors and medications: Some people are born with thin tooth enamel. Also, some antibiotics taken during childhood can cause tooth discoloration.
