What is the reason for black inside teeth

Because people often drink tea and coffee, and some people like to eat sweets, they will have some oral problems with their teeth. In fact, oral problems are not important. The key is to clean the teeth. This is a very important step. Some people will find that the inside of their teeth are black when they smile. This is like rust, and they need to pay attention to whitening their teeth.

Steps/Methods:

1. Rinse your mouth with vinegar. Get some aged vinegar or white vinegar. Hold it in your mouth for 1 to 3 minutes, then spit it out and brush your teeth. Your teeth will feel very sour and numb at first. After a period of time, the effect is more obvious, and it can be used as an emergency method. For example, if you feel your teeth are yellow and you are not confident before a date, you can consider doing it.

2. Add baking soda to your teeth. This method is well known to everyone. Similarly, yeast powder can also be used to help whiten teeth. After brushing three times, your teeth will be as white as jade, and the annoying tooth rust will automatically disappear. This method is simple and easy to operate, and the materials are easy to prepare, making it an excellent choice. The effect is also very good.

3. Another method is to try using strawberries. The specific method is to dry the strawberries first, and then grind them into powder after the water is dried up. Then prepare the baking powder, mix the baking powder with strawberry powder, and stir well. Then dip a toothbrush in the mixed powder, brush it on your teeth, and rinse your teeth after five minutes.

Note:

In fact, we should pay attention to the daily care of our teeth, drink less tea and coffee, smoke less, and pay attention to the method of brushing our teeth, brushing the inside and outside. This is the best way to keep your teeth clean for a long time. Instead of waiting until the problem of yellow teeth or black teeth actually appears before solving it. I hope everyone has a healthy set of teeth and can live confidently every day.
