Do you try to hide your smile due to your discoloured, yellowing teeth? If so, you should figure out why this is happening rather than keeping your mouth shut! All of us desire teeth that shine bright and white, but we also tend to neglect our nighttime oral hygiene routine, eat sugary and acidic foods whenever we can, and smoke cigarettes without hesitation. Well, sorry to tell you, these are just the causes of yellow teeth you should be careful avout.

Not only yellow teeth, but also gum diseases, bad breath, tooth decay, inflammation, and teeth discolouration are all risks increased by these habits and other oral health blunders.

Health Shots got in touch with Dr Amit Kapoor, who is also a Cosmetic Laser Surgeon and Dentofacial Orthopaedics Surgeon, to find out all the causes of yellow teeth because finding the cause can help you remove the problem from its root.

Here are 7 major causes yellow teeth:

1. Plaque buildup

Plaque buildup is likely if you practise poor dental hygiene and don’t frequently brush, floss, or rinse your mouth. Bacteria in plaque can erode tooth enamel and cause cavities. However, bigger issues develop if plaque is allowed to remain on your teeth and turns into tartar. Tartar is a hard yellowish crust, often known as calculus, that develops both below and above the gum line. It may be avoided by following proper oral hygiene.

2. Tea and coffee

Daily consumption of highly coloured beverages such as tea, coffee, carbonated sodas, wines, and even green tea can stain your teeth. These substances might even cause long term teeth discoloration if they penetrate the enamel. Try to restrict the amount of these drinks you consume, and if you do, make sure to rinse your mouth out thoroughly with water. Brush your teeth twice daily as well.

3. Sugary and starchy foods

Along with beverages, some foods, such as apples, potatoes, pasta, berries, tomatoes, etc., can stick to the teeth and leave behind stains that can turn the teeth yellow, brown, green, or orange. Even salads with vinegar dressing have the potential to leave stains. Reduce your intake of these foods or other extremely acidic foods and beverages to prevent it and protect your enamel.

4. Ageing

The next cause of yellow teeth is ageing because as people age, their teeth’s enamel thins out from normal wear and tear, exposing the dentin’s natural yellow colour. This can happen more quickly if the teeth suffer trauma (caused by fall, blow or shock).

5. Smoking

While the majority of people are aware that smoking is detrimental to their health, it is equally harmful to your dental health too. Dr Kapoor says, “Smoking, pan masala, tobacco, etc. include nicotine and tar that leave teeth with stains that are difficult to remove and can cause yellow teeth.” In fact, they can also lead to gum diseases and mouth cancers in some cases. Quit consuming all these harmful substances for the sake of your dental health.

6. Diseases

Diseases that damage the enamel and dentin, including jaundice, are a less known cause of yellow teeth. Certain illnesses or infection during pregnancy might impair the development of the baby’s enamel and result in discoloration. Yellow or discoloured teeth might also appear in head and neck cancer patients who are undergoing chemotherapy. In this case, discoloration is more of a brownish colour.

7. Medication

Teeth discoloration is a known side effect of several antibiotics, antidepressants, and blood pressure medications. In fact, using tetracycline antibiotics during pregnancy can also cause yellow teeth. If a medicine has caused an unpleasant reaction in you, talk to your doctor.
