Tại sao tôi nên vệ sinh răng miệng 6 tháng một lần?

You may brush twice a day, floss religiously, and avoid sugary drinks—but if you’re skipping regular dental cleanings, you’re missing a key part of your oral health routine. Dentists around the world recommend professional teeth cleaning every six months. But is it really necessary? And what happens if you don’t go?

Let’s explore the science, the benefits, and the long-term importance of getting your teeth professionally cleaned twice a year.

What Is Professional Teeth Cleaning?

Teeth cleaning, also called dental prophylaxis, is a procedure performed by a dentist or hygienist to remove plaque, tartar, and stains that cannot be eliminated through regular brushing and flossing.

What’s Included in a Typical Cleaning Appointment?

  • Plaque and tartar removal using ultrasonic or manual scalers
  • Polishing to remove surface stains and make teeth smooth
  • Fluoride application (optional, but recommended for added protection)
  • Flossing and rinsing
  • Oral examination to check for early signs of problems like gum disease, decay, or oral cancer

Unlike home care, which is limited to soft plaque removal, a professional cleaning uses specialized tools to clean above and below the gumline, where bacteria thrive.


Why Every 6 Months?

You might wonder, “Why not once a year or whenever something feels wrong?”

The answer lies in prevention and early detection.
