What Causes Teeth to Discolour?


Teeth discolouration occurs when the teeth are devoid of proper care and exposed to staining. Teeth discolouration are caused by numerous factors:

Food materials
Certain food items and drinks such as apples, potatoes, cold drinks, tea, coffee and alcohol can cause your teeth to discolour. They change the pH of the mouth leading to staining of the teeth.

Disease and treatment
Diseases can also cause teeth discolouration. Diseases related to mouth and teeth lead to staining. If a pregnant woman develops any kind of infection, this can result in tooth discolouration in the newborn. Even some treatments such as radiation therapy and chemotherapy can also cause teeth discolouration.
Improper oral hygiene
A proper dental care is essential to prevent teeth discolouration. If you are not regular in brushing and flossing properly, this results in plaque deposition, thereby resulting in teeth discolouration. Accumulation of food particles on the teeth surface causes yellowing of the teeth and tooth decay.

Excessive use of fluoride
Excessive use of toothpaste rich in fluoride or use of water high in fluoride content for rinsing causes fluorosis. Fluorosis results in the appearance of thick white stains, followed by browning of the teeth and tooth decay.

Medications also cause teeth discolouration. Certain antihistamines such as Benadryl, antibiotics and drugs for high blood pressure are also responsible for staining of teeth. Chlorhexidine and cetylpyridinium chloride present in iron syrups and mouthwashes respectively also cause teeth discolouration. Tetracycline and doxycycline are also known to cause teeth staining in children.
Ageing is another important factor responsible for teeth discolouration. Ageing leads to wearing of the enamel which exposes the yellow dentine. Old people who smoke and drink are more prone to develop teeth discolouration.

Less production of saliva
Saliva protects your mouth from all kinds of microbial infection. It also maintains the pH of the mouth. Less production of saliva due to any infection or disease results in plaque formation and teeth discolouration. Teeth discolouration is very easy to prevent. By making few changes in the lifestyle accompanied by a proper oral hygiene, you can always keep your teeth healthy, white and shiny.
