Black stains on teeth are primarily composed of dental plaque, tartar, and pigment deposits. Long-term accumulation not only affects aesthetics but may also lead to oral diseases. Under normal circumstances, black stains on teeth can be removed through the use of mouthwash, proper tooth brushing, dental floss and interdental brushes, dietary adjustments, and regular dental cleanings.

1. Mouthwash: Using an antimicrobial mouthwash can reduce oral bacteria and assist in maintaining oral hygiene.

2. Proper Tooth Brushing: Brush your teeth at least twice daily for a minimum of two minutes each time, using fluoride toothpaste and the correct brushing technique to ensure all tooth surfaces are cleaned.

3. Use of Dental Floss and Interdental Brushes: Use dental floss and interdental brushes daily to remove food debris and bacteria from between the teeth, preventing the formation of dental plaque.

4. Dietary Adjustments: Reduce consumption of highly pigmented foods and beverages such as coffee, tea, red wine, and tobacco, which are major causes of tooth discoloration.

5. Regular Dental Cleanings: Have a professional dental cleaning once every six months to a year. A dentist or dental hygienist will use an ultrasonic scaler to remove tartar and deep stains, which is the most effective method.

In daily life, it is recommended to maintain good oral hygiene habits and schedule regular dental checkups, which also help prevent black stains on teeth.
