What Causes Yellowing Of Teeth?

There are multiple causes of yellowing of teeth, categorised under tooth discoloration.

Tooth discoloration is when the color of your teeth change from white to yellow to darker colors, either due to extrinsic or intrinsic causes or ageing. 

Extrinsic causes of tooth discoloration are those caused by objects or factors outside your body. These may include foods and drinks, tobacco use and poor dental hygiene.

Intrinsic causes of tooth discoloration include factors that originate within your oral cavity or body. These may be associated with your genetics, certain types of medications, excessive fluoride intake or any type of dental injury.

Intrinsic tooth discoloration is discoloration within the dentin, has a pulpal or systemic origin and is much more permanent when compared to extrinsic teeth discoloration. 

Some of the potential causes of tooth discolouration or yellowing of teeth are: 

Coffee, Tea And Wine

Coffee, Tea and Wine are known to cause teeth stains and yellowing of teeth.

Tannins, a type of organic substance found in coffee, tea and wine, build up on the tooth enamel and result in yellowing of teeth.

Poor Oral Hygiene

Not brushing your teeth daily after every meal or at least 2 times for two minutes each as recommended by ADA, may lead to plaque accumulation and tartar formation.

Plaque, calculus or tartar causes yellowing of teeth and also increases the risk of periodontal diseases.

Chromogenic bacteria have also been reported to cause stains on your teeth commonly at the gingival margin of the tooth. 

Bad Habits: Tobacco Use

Tobacco in any form causes discoloration of teeth. Discoloration caused by tobacco is not yellow but more dark brown or black. 

Medications 

Medications like Chlorhexidine, tetracycline and phenolic mouth rinses cause yellow discoloration of teeth.

According to a review published in the International Journal Of Dental Hygiene, Chlorhexidine mouthwash resulted in more significant tooth discoloration compared to chlorhexidine gel.

Tetracycline discoloration occurs below the gum line most commonly involving the anterior teeth, in children exposed to tetracycline during pregnancy or during the early years of tooth development.

Tetracycline also causes tooth discoloration in some adults but these stains are not permanent as in children.

Genetic And Metabolic Disorders

Metabolic disorders like hyperbilirubinemia cause yellowing of teeth.

Genetic disorders like amelogenesis imperfecta, dentin dysplasia and epidermolysis bullosa also result in yellowing of teeth.

Dental Injury

Injury in early childhood may disturb the tooth germ and can be one of the causes of tooth discoloration and yellowing of teeth.

Trauma in adulthood may also lead to discoloration of teeth.

Dental Materials

Dental materials such as composite and GIC lead to yellowish discoloration of the teeth.

Ageing

As you grow older, the outer layer of teeth called enamel wears and the inner dentin is exposed, revealing an off-white appearance.

Excessive Fluoride

Fluoride in adequate amounts is crucial for healthy and strong teeth.

However, excessive fluoride from environmental sources such as high fluoride content in the local water supply or from excessive use of fluoride containing toothpaste and mouthrinses can cause teeth discoloration.
