How to Brush and Floss Properly: Dentist-Approved Techniques
December 18, 2025
By Williamstown Road Dental Surgery
Beyond only keeping your teeth clean, maintaining proper oral hygiene is essential for your general well-being. At Williamstown Road Dental Surgery, we often remind our patients that the key to healthy teeth and gums starts with mastering the basics: brushing and flossing.
In this blog, our dentists in Williamstown share expert-approved techniques for brushing and flossing properly, helping you prevent cavities, gum disease, and costly dental treatments down the road.
Why Proper Brushing and Flossing Matters
Poor oral hygiene can lead to more than just bad breath—it can cause gum inflammation, tooth decay, and even systemic health problems like heart disease and diabetes. Brushing and flossing effectively removes plaque, a sticky film of bacteria that forms on your teeth and gums. Plaque turns into tartar if it is not cleaned, and only a dentist can remove it.
Dentist-Approved Brushing Techniques

It’s crucial to brush your teeth for two minutes twice a day, but how you brush is just as important as how frequently you brush.
Choose the Right Toothbrush
- Use a toothbrush with soft bristles to prevent harm to your gums and enamel.
- Electric toothbrushes are highly recommended, especially for those with limited mobility or children.
- Every three months or when the bristles begin to fray, replace your toothbrush.
Use Fluoride Toothpaste
Fluoride helps strengthen tooth enamel and prevents cavities. Use a pea-sized amount of fluoride toothpaste for effective cleaning.
The Proper Brushing Technique
- Maintain a 45-degree angle between your toothbrush and your gums
- Use gentle, circular motions—not back-and-forth scrubbing.
- Brush all surfaces: outer, inner, and chewing surfaces of your teeth.
- Remember to brush the roof of your mouth and your tongue to get rid of bacteria and improve your breath.
- Spit out toothpaste but don’t rinse with water right away—let the fluoride work longer.
How Long Should You Brush?
Aim for 2 full minutes. You can spend 30 seconds on each of the four quadrants of your mouth: upper right, upper left, lower right, and lower left.
Dentist-Approved Flossing Techniques
Only roughly 60% of your tooth surfaces are cleaned by brushing alone. Flossing is necessary to get rid of food particles and plaque in the remaining 40%, which is in between the teeth.
Types of Dental Floss
- Waxed floss:Slips easily between tight teeth.
- Unwaxed floss:Thin and more fibrous
- Floss picks or holders:Great for people with limited dexterity.
- Water flossers:Helpful for braces or dental work.
How to Floss Properly
- Break off about 45 cm of floss. The majority of it should be wound around your middle fingers, leaving 5–7 cm free.
- Using a sawing motion, carefully glide the floss between your teeth.
- Curve the floss around each tooth in a “C†shape, sliding it up and down below the gumline.
- For every tooth, use a fresh piece of floss.
Common Flossing Mistakes to Avoid
- Snapping the floss into the gums (can cause trauma)
- Not flossing behind the back teeth
- Reusing the same section of floss repeatedly
Brushing vs. Flossing – Which Comes First?
You might be surprised to know that flossing before brushing is often more effective. It loosens plaque and debris, allowing the fluoride in toothpaste to reach between your teeth more efficiently.
How Often Should You Floss?
At least once a day, ideally right before bed, floss. Night-time flossing removes food particles that would otherwise remain in your mouth while you sleep, reducing the risk of bacteria build-up overnight.
Tips for Parents: Teaching Kids Good Habits

At Williamstown Road Dental Surgery, we see many young patients and always encourage starting early. Here’s how to get your child into the habit:
- As soon as the first tooth appears, begin brushing.
- Supervise brushing until your child is at least 8 years old.
- Apply a thin layer of fluoride toothpaste and a toothbrush the size of a child.
- Make brushing fun with timers, songs, or apps.
- Lead by example—brush and floss with them!
What About Mouthwash?
Mouthwash can be a great addition to your routine, especially those with antibacterial or fluoride properties. However, it should not replace brushing or flossing. Use mouthwash after brushing, or at a different time of the day for a fresh boost.
Signs You May Not Be Brushing or Flossing Correctly
Watch out for these signs:
- Bleeding gums
