How to remove the black spots inside teeth

Black or yellow teeth give people a feeling of being sloppy and dirty. It greatly reduces one's personal image. However, this situation may occur if you do not pay attention to oral care on a daily basis. Furthermore, people who like to drink tea, coffee and smoke are also more likely to have darker teeth. For those people whose teeth become darker, they should pay more attention to developing scientific conditioning methods in their daily lives. So how should they treat darker teeth?

Baking soda is effective for black teeth caused by exogenous factors, such as tea stains, cigarette stains, etc. Baking soda is ammonium bicarbonate, a weak acid. Soda is sodium carbonate, a weak base. Tartar breaks down when it comes into contact with acid, so baking soda has a certain effect.

Method 1: Use baking soda and salt together

Add an appropriate amount of baking soda, some salt and some water, mix well, not too thin, enough to be able to be applied on the teeth, then use a clean cloth or toothbrush to apply a small amount and gently brush your teeth, that's it! It's more convenient to buy it in the supermarket, as the pharmacy may not have it. A pack of 500G is estimated to cost around 4.5 yuan.

Method 2: Baking soda can be used together with toothpaste

Just sprinkle a little on your toothpaste when brushing your teeth. However, you can only use a mixture of baking soda and toothpaste to brush your teeth once a day, because baking soda is alkaline and using too much will damage your teeth. It is best not to use it alone. Baking soda can be purchased at general pharmacies. If you don’t buy much, 3 or 4 cups are enough. However, soda tablets are more commonly sold in pharmacies, while baking soda can be bought in supermarkets.

Method 3: When brushing your teeth, using some yeast powder on the toothbrush can help whiten your teeth.

Method 4: Chew the raw peanuts, don’t swallow them, and use the peanut crumbs as toothpaste to brush your teeth, which can make your teeth whiter.

Method 5: Hold the vinegar at home (either aged vinegar or white vinegar, but not vinegar essence) in your mouth for 1 to 3 minutes, then spit it out and brush your teeth. (This method is not recommended. It is okay to use it occasionally. Frequent use will make your teeth sour.)

Method 6: Teeth cleaning: I have tried it, but it is only a temporary solution and not a permanent cure. Teeth cleaning does not make your teeth whiter, it just makes them cleaner. I heard from a doctor friend that long-term teeth cleaning is very bad for teeth.

Method 7: Cold light whitening: It can make teeth whiter, and the effect is quite obvious. The principle is to use a special bleaching agent, which is catalyzed by cold light, and then releases redox reaction with the pigments on the surface and deep layers of the teeth to whiten the teeth.

Method 8: Of course, you need to brush your teeth frequently, and don’t just do it hastily. Be sure to brush your teeth once in the morning and evening, and for at least three minutes, so that you can thoroughly clean your teeth.

Method nine: tooth powder. This is the most effective method with no side effects. Since you have to brush your teeth every day anyway, you might as well use tooth powder as toothpaste. The effect is obvious. Especially it works better on those with tea stains, cigarette stains and coffee stains.
