Many people are worried about 'yellow teeth' despite brushing three times a day without fail. Incorrect brushing may have caused the yellow teeth. Dr. Perak Hamid, a dentist in the UK, shared 'common brushing mistakes' in the Daily Mail.

 

The first is not wetting the toothbrush with water when brushing. It is commonly misunderstood that a stiff toothbrush helps remove stains or foreign substances on the teeth. However, according to Dr. Hamid, brushing with a stiff toothbrush can wear down the teeth and cause them to turn yellow.

 

The surface of the tooth is made of hard enamel, with the inner part consisting of soft dentin and internal nerve tissue. The enamel protects the dentin and nerve tissue from external stimuli. However, if exposed to vigorous brushing repeatedly, the enamel wears away, revealing yellowish dentin, which allows external stimuli to easily reach the nerve tissue.

The second is to brush your teeth immediately after eating foods high in acid content. Consuming foods with high acidity, such as fruit juice, carbonated drinks, alcohol, and coffee, leaves acid residues on the surface of the teeth. Brushing right after intake can cause the acids on the tooth surface to react with the components in the toothpaste, leading to tooth erosion. Dr. Hamid said that this habit ultimately results in yellowing teeth. In such cases, it is better to rinse your mouth with mouthwash or water to remove the acidity and wait 30 minutes before brushing.

 

Meanwhile, teeth can appear yellowish due to genetic causes. Tooth color varies depending on the thickness of enamel and dentin, with thicker white enamel appearing whiter, and thicker yellowish dentin appearing more yellow. Genetically, if the dentin is thick, the teeth appear yellow from a young age.

 

The best way to prevent tooth discoloration is to avoid consuming foods with high pigment content. Especially if quitting coffee is difficult, it is better to drink a latte with milk. The protein 'casein' found in milk helps prevent tooth discoloration.

I think I've heard a lot about coffee stories.

If you drink coffee and do a little gargling

 

They say it helps a little.

 

Don't pick up the toothbrush with your palm.

Gently pinch with your fingers
