Why do teeth become black due to tooth decay? It turns out they are the ones causing trouble

There are many such examples in life, where originally white teeth suddenly turn black and develop cavities. In fact, it is normal to have such symptoms. Tooth decay is the key to blackening of teeth. In addition, drinking tea, coffee and smoking can also make teeth darker.

1. Tooth decay makes teeth turn black: If large holes appear on the surface of the teeth, or if caries occur between teeth, then the teeth are destined to turn black.

Treatment for tooth decay that turns teeth black: If you find tooth decay, the first thing you should do is brush your teeth well to control the degree of tooth decay, and then go to the hospital immediately to fill the tooth. The doctor will grind away and clean the decayed areas of the teeth, and then use a resin material that is very close to the color of the teeth to fill the missing areas.

After the filling, the black spots on the teeth disappeared, but we should not forget the lesson. In the future, we should insist on brushing our teeth. We should also brush our teeth or rinse our mouths in time after eating sweets or drinking beverages.

2. Drinking tea, coffee and smoking make teeth black: Normally speaking, drinking tea is good for teeth, so why does it make teeth black? This is because after eating, a layer of transparent mucous membrane called dental plaque will be formed on our teeth. If you drink strong tea or colored beverages such as coffee and black tea at this time, the pigments will be absorbed onto the dental plaque, resulting in pigment precipitation. In addition, smoking will also form a kind of "smoke stains" on the teeth. For people who like to drink carbonated drinks, the saccharin and acidic substances added to the drinks will also cause certain corrosion to the teeth.

Treatment for darkening of teeth caused by exogenous pigments: If your teeth turn dark, you can try brushing your teeth carefully. Brushing your teeth with salt and baking soda is one solution. You can also use teeth cleaning or cold light whitening to get rid of dark teeth.
