Why are the pits and grooves of teeth black but there are no holes?

If the pits and fissures of the teeth turn black, even if there are no cavities, it means that the teeth are affected by bacteria, causing caries. In addition, the black pits and fissures of the teeth are also related to incomplete development of the enamel and poor diet, which leads to pigment deposition. The most common ones are caries, tetracycline teeth and fluorosis. Therefore, when this happens, you should go to the hospital for examination in time, receive good treatment, and develop good oral hygiene habits.

Why are the pits and grooves of teeth black but there are no holes?

1. Dental enamel hypoplasia

That is, during the development of teeth, the enamel lacks certain substances or is affected by harmful substances, resulting in tooth development disorders such as enamel defects. Therefore, during the development of teeth, it is necessary to have a balanced nutrition and be careful not to ingest harmful substances.

2. Pigmentation

For example, some patients do not pay attention to oral hygiene, which causes some colored food stains to deposit on the surface of the teeth, such as coffee stains, tea stains, smoke stains and colored food. If they are not removed in time, these pigments will slowly deposit and penetrate into the teeth, eventually causing the teeth to turn black, which requires timely treatment.

3. Dental fluorosis

It is mainly caused by excessive fluoride in drinking water, which causes tooth enamel to discolor and then plaque or defects to appear, eventually causing the teeth to turn black. People often use cold light whitening, porcelain teeth and dental veneers to treat fluorosis.

4. Tetracycline Teeth

The main reason for the darkening of teeth is due to excessive use of tetracycline drugs during the development of teeth. So how to whiten tetracycline teeth? Dental veneers, porcelain teeth and cosmetic crowns are often used clinically to whiten black teeth, allowing customers to smile confidently from then on.

5. Tooth decay

This is mainly due to inadequate oral hygiene, which causes tooth corrosion. Over time, the teeth become soft and eventually form black cavities. Clinically, fillings are often used to treat mild caries, and root canal treatment is required for caries that have damaged the pulp.
