How does tooth blacken do? Small coup
'teeth like a bottle rhinoceros' means that the teeth are white and neat, such as bottle seeds. However, many people have blackened teeth, which greatly affects their overall temperament. So, why are the teeth black? If you also want to have such white teeth, you can try these 5 tooth whitening tips.
Causes of tooth blackening:
1. Exogenous blackening: habitually drinking coffee, coke, strong tea and other foods with high dark pigment for a long time. Over time, the dark pigment stays on the surface of the teeth and even penetrates into the inside of the teeth, resulting in signs of blackening inside the teeth.
2. Endogenous blackening: mostly occurs in some oral diseases. Because the bacteria contained in these diseases produce some acidic substances through chemical reaction with food residues, which not only corrode the enamel, but also make the teeth blacken and damaged with the attachment of some pigments, and gradually erode into the dentin and other tissues. Therefore, the teeth are blackened.
5 Teeth Whitening Tips:
Tooth powder whitening
Get up early and brush once before going to bed. It will take about 5-10 days. However, if the color of your teeth is yellow, you may have to go to various dental clinics for help.
Floss descaling method
Removing tartar is the premise of whitening teeth. Removing tartar advocates the use of floss. Dental floss is composed of several fibers, which is flat and banded. It can easily pass through the contact point between teeth. Long term use will not widen the gap between teeth.
Brown sugar brushing
Take an appropriate amount of brown sugar and put it into the inlet for about 15 minutes, so that the whole mouth of teeth are soaked in sugar solution, brush with a toothbrush for 23 minutes repeatedly, and then brush with light salt water for 12 minutes, once in the morning and evening every day for 1 week.
Alum brushing

A cup of Tieguanyin after dinner
