Regular use of pan masala can cause deep stains on the teeth because it contains tobacco and strong colouring agents that stick to the outer enamel layer. These stains often do not go away with simple brushing or basic cleaning, and they may return if the habit continues. The most effective treatment is professional dental scaling and polishing done by a dentist. In more stubborn cases, a procedure called deep cleaning or ultrasonic scaling may be needed to remove deposits below the gum line. If the stains have penetrated deeper into the enamel, cosmetic treatments such as teeth whitening or dental bleaching can help improve the appearance. In severe cases, dental veneers (thin porcelain shells placed on the front of teeth to improve appearance) may be suggested. However, the most important step is to stop or reduce pan masala use, as continued use will cause new stains even after treatment. Maintaining good oral hygiene by brushing twice daily, using fluoride toothpaste, and regular dental check-ups every six months will help keep teeth cleaner and healthier in the long term.
