5 Reasons of Yellow Teeth

A very best friend of mine went on a date last weekend but when asked about how it went she only said His teeth were like little kernels of corn peeking out from behind his lips – a sunny shade of yellow. Yellow teeth can often cause people to be conscious of their smile.  Luckily, there are many options to help change the colour of your teeth to a whiter shade. It is essential to look after the yellow stains on the teeth. We’re here with certain reasons responsible for yellow teeth.

5 Reasons of Yellow Teeth

  • Poor Dental Hygiene: Regular flossing and brushing are important for maintaining oral health. Inadequate brushing and flossing can lead to the buildup of plaque. Over time, if not removed through proper oral hygiene, plaque hardens into tartar, which can cause teeth to appear yellowish. Additionally, plaque and tartar can harbour bacteria that produce acids, leading to enamel erosion and further discolouration.

  • Dietary habits: Many foods and beverages contain chromogens, which are highly pigmented molecules that easily adhere to tooth enamel. Coffee, tea, red wine, and certain fruits like berries are particularly notorious for staining teeth. Acids found in these foods and beverages can also weaken enamel, making it more susceptible to staining. While staining from food and drink is often superficial, over time it can penetrate the enamel and cause discolouration.

  • Wear and tear of enamel: As teeth age, they naturally undergo wear and tear from chewing and exposure to acidic substances in food and drink. Over time, this wear can lead to thinning of the enamel—the outer protective layer of the teeth. As enamel thins, the underlying dentin, which is naturally yellowish, becomes more visible. This can cause teeth to appear yellow as individuals age. Additionally, certain foods and beverages can contribute to staining, further exacerbating discolouration. While most teeth tend to be yellow with age due to enamel thinning, some may take on a greyish tint when exposed to long-lasting food stains.

  • Tobacco use: Smoking or chewing tobacco introduces tar and nicotine into the mouth, both of which can stain teeth. Tar is a dark, sticky substance that easily adheres to tooth enamel, leading to yellow or brown discolouration. Nicotine, on the other hand, constricts blood vessels in the gums, reducing blood flow and oxygen delivery to oral tissues. This can cause gums to recede, exposing more of the tooth surface and making it easier for stains to accumulate.

  • Grinding: Tooth grinding, also known as bruxism, is an unconscious habit that some individuals develop, particularly when stressed, and often occurs during sleep. This habit can be quite detrimental to tooth enamel, as the repeated grinding can weaken it to the extent of causing cracks and yellowing.

CONCLUSION

After consuming foods that are known to cause staining or contain high acidity, it’s best to avoid brushing immediately as the enamel may be temporarily softened. Instead, rinsing your mouth thoroughly with water can help wash away acids and staining compounds. Another helpful tip is to stimulate saliva production by chewing sugar-free gum or eating crunchy fruits and vegetables, which can aid in neutralizing acids and promoting remineralization of the enamel. Developing these habits can contribute to maintaining healthy, clean, and white teeth over time. If teeth discolouration persists or if you’re seeking a brighter smile, consulting with a dentist about professional teeth whitening options is recommended.
