10 Common reasons behind your yellow teeth


Everybody loves to have pearly white teeth. But if you are among those who have not-so-white teeth, it's time you should pay attention to it and find out what is causing the yellowing of your teeth. Treating your yellow teeth like other dental conditions is not urgent, but if left untreated can impact your confidence level and beautiful smile. 

Interestingly, enhancing your teeth' color is as simple as changing what you are eating and drinking while also refining your oral care routine. You might even benefit from teeth whitening treatment by your dentist.


Here are 10 solid reasons behind your yellow teeth:


1. Genes: Sometimes, the color of the teeth runs in your family. If your parent's teeth are yellow, you will likely have a similar hue. The color shades of teeth are reddish-brown, reddish grey, grey, and reddish-yellow, and the color depth varies from light to dark.


2. Dentin: Your teeth will be yellow when you have thin enamel, and the dentin is seen through it. The color of the dentin varies from yellow to brownish, and it is often the leading cause of the yellow color when you look at them in the mirror. 


3. Enamel is worn out: With increasing age, your enamel also wears away because of exposure to food, drink, and chewing. Most teeth turn yellow when the enamel becomes thin while processing these foods throughout our lifetime, and some also adopt a gray shade when they are missed with long-lasting food stains.


4. Smoking: Nicotine you smoke has many impurities that stick onto your teeth and stain them. Over time it may develop into tartar and can ruin your oral health. Smoking is not only bad for your health but also for your teeth. 


5. Food: There are a wide variety of foods that stains your teeth. Some examples are tomatoes in the pasta sauce, beverages like Pepsi and cola, spices in your curry, and berries. These consist of pigments cling to your tooth enamel and stain its surface. Also, a healthy salad with balsamic vinegar dressing can leave behind a color stain on your teeth.


6. Drinks: Two significant causes of yellow teeth are coffee and tea. In addition, red and white wine also stains your teeth yellow. Other things include light and dark sodas and sports drinks with artificial flavor.


7. Antibiotics: Antibiotics having tetracycline can stain your teeth while affecting your gums. Tetracycline is an antibiotic that is used for the treatment of some common infectious diseases in children below as well as adults. While tetracycline and oxytetracycline cause yellow coloring of your teeth, chlortetracycline makes your teeth grey-brown.


8. Fluorosis: Fluoride is good for your teeth, but when it is in excess, it causes yellow or brown spots known as fluorosis. Fluoridated water, toothpaste with fluoride, and some of the prescribed fluoride tablets are significant sources of fluoride. Consult your dentist if you think you or your child are taking too much of it through all the above means.


9. Accidents: Impacts of accidents or any physical trauma can damage your tooth enamel and affect the interior of your tooth, thereby causing discoloration. If there is bleeding, then it needs medical attention.


10. Grinding of teeth: Tooth grinding is an insensible incident that some people have when they are under stress, especially while sleeping. It is also called bruxism. It is very harmful to your tooth enamel that weakens your teeth to the point of cracking and yellowing.
