When done properly, hand disinfection can significantly decrease the risk of infection. However, it is important to note that hand disinfection is most effective when done correctly and consistently, including using the right amount of hand sanitizer or soap and thoroughly covering all surfaces of the hands.

Some factors that can contribute to tartar buildup include genetics, diet high in sugar and carbohydrates, smoking, and certain medical conditions. Regular dental cleanings and check-ups are important to prevent tartar buildup and maintain good oral health. **
