Answer:
B. Regular professional teeth cleaning has no effect on dental health.
Step-by-step explanation:
Research consistently supports the idea that regular professional teeth cleaning, also known as dental cleanings or dental hygiene appointments, has a positive effect on dental health. These cleanings help remove plaque and tartar buildup, which can contribute to dental issues like cavities and gum disease. Therefore, maintaining good dental hygiene practices, including regular dental cleanings, is generally recommended for overall oral health. Handwashing is also a well-established and essential hygiene practice for preventing the spread of infectious diseases.
