What is the reason for yellow tooth roots

Everyone wants to have a set of white teeth, which not only makes them look healthier, but also makes them look clean and beautiful. However, some people are very distressed because the roots of their teeth are very yellow. They are even afraid to open their mouths to speak. What is the reason for the yellow roots of their teeth? There are several reasons for yellow tooth roots, both exogenous and endogenous. For example, some people like to smoke, which can cause yellow teeth roots, and some people like to drink coffee, which can also cause yellow teeth roots.

1. Exogenous yellow teeth

Because food pigments stick to the tooth surface, they appear yellow or gray; the soot from smoking, pigments from beverages, coffee, tea, etc. stick to the teeth and appear yellow-gray.

2. Endogenous yellow teeth

When teeth are affected by certain elements, the pigment is not on the surface of the teeth but inside the tooth tissue. There are two main types: fluorosis and tetracycline.

3. Physiological tooth color changes

As people age and use their teeth over a long period of time, their teeth will gradually change slightly in color. Just like your own skin, it is white and smooth when you are young, but gradually becomes dull as you get older. These are all unavoidable. Don’t worry too much about such color changes. If you are very concerned about your appearance, you can use teeth whitening methods to improve your appearance, just like skin care.

4. Lack of nutrition

Some teeth may have discoloration of the crown due to pulp necrosis and lack of nutrition.

5. Hygiene habits

Some people do not pay attention to oral hygiene and do not have the habit of brushing their teeth in the morning and evening, resulting in a layer of food residues, soft plaque, tartar, smoke stains, tea stains, etc. accumulated on the surface of their teeth. These "yellow teeth" are not caused by the teeth themselves turning yellow, but by not paying attention to oral hygiene.
