Toothbrushing and flossing are part of a group of factors that help to combat tooth decay/caries and gum disease. It is something we should be doing often and consistently. Although it is something we may have been doing for years there is always ways we can improve. I find it crazy to believe that I was unaware that I had been brushing incorrectly for years. I did not realise that you should spit and not rinse with water throughout brushing until I started dental school. Hard to believe, I know. We can always learn and improve, so please enjoy these tips and tricks on how to improve your oral hygiene.

    Frequently Asked Questions about Toothbrushing

  • Which is better electric toothbrush or manual?
  • This has been a controversial topic for many years. I first want to start by saying that any brushing is better than no brushing. But if we were to compare electric and manual brushing the current studies are starting to show that power brushing is more superior than manual brushing. Often being able to remove about 5-20% more biofilm/plaque than the manual toothbrush. There are many different types of electric toothbrushes, but currently it appears the 3D rotating toothbrush is slightly better than the others. This is constantly being studied and therefore can change in the future. (click here to see the picture above)

  • Which is better to clean at night or in the morning?
  • It is better you clean both morning and night as you often do not clean all the bacteria the first time. However, I do like to say you brush in the morning to keep your friends and you brush at night to keep your teeth. The reason why it is very important to brush at night is because you do not have the saliva protective factors at night time while you sleep like you do during the day when your awake. There night brushing over morning, however both are important.

  • Which floss should I use?
  • I personally say what ever one will make you floss (The one you prefer). If you find it difficult to do the action then you may like the floss sticks. The main thing is as long as you are doing it, your oral heal practitioner will be happy.

  • What toothpaste should I use?
  • This has been discussed in further detail in another page called toothpaste and fluoride. Click this link to find out more.

  • How long should I brush for?
  • It is recommended that you brush for at least 2 minutes. This allows time for you to reach all the difficult spots in the mouth

  • How do I reach my upper wisdom teeth when I brush my teeth?
  • This can be difficult because of two reasons; how far your third molars are in the back of your mouth and that your jaw joint can block the brush head. The trick is you need to slide your jaw to the same side that you are brushing, this will move the jaw joint out of the way and allow you to reach that tooth. It also helps if you use a small brush head. Ask your oral health practitioner to show you how to do this.

    Common Mistakes

    (click here to see the Brushing Mistakes 2)


  • A common mistake is that people often do a back and forth motion instead of the correct method of small circles.
  • The problem with back and forth motions is that it tends to miss the gums. Your not just brushing your square shaped teeth, you are wanting to brush the semi-circular area where the gums and the teeth meet. Brushing in small circles helps to reach that area and ensure your cleaning properly.

  • A common mistake is that people brush too soon after eating
  • If you have an acidic drink like coca-cola, or food with lots of acid (example: lemon, vinegar) or recently vomited (morning sickness) you risk brushing that acid around your mouth and possibly eroding some tooth structure. Therefore it is best to wait 30 minutes or so to allow the saliva to buffer your mouths acidic environment. It might be a good idea to also rinse with some salt water solution, milk or plain water before brushing to help neutralise your mouths acidic environment

  • A common mistake is that people use a large toothbrush head
  • Often people get a large toothbrush head to be more efficient, however this no the case; as you often miss spots where this large toothbrush head can not reach. This is especially the case on lower teeth on the tongue side as well as the cheek side of upper wisdom teeth. Smaller head toothbrushes help you to reach these areas

  • A common mistake is that people use harsh toothpastes
  • Abrasive toothpastes (that contain ingredients like charcoal) or whitening toothpastes can result in sensitivity especially if you have exposed dentine (the second layer of teeth) this can make it painful to have cold drinks. Talk more with your oral health practitioner about the right toothpaste for you.

  • A common mistake is that people brush too hard or with hard bristle toothbrush head.
  • Often people use a hard bristle toothbrush because they want to scrub the bacteria away off the tooth structure. The intention is great but unfortunately, usually you have a hard brushing technique and in fact you end up removing tooth structure as well. As a result using a soft to medium bristle brush is often adequate. If you want to see if you brush hard grab an extra soft toothbrush and see how long it lasts. If it is less than a few weeks before you see worn down bristles you may need to adjust how hard you are brushing because it is too hard.

  • A common mistake is people using a worn down toothbrush
  • Bristles generally wear down after 2-3 months of use. Once they have worn down they are not as effective as the bristles have now spread out. It is like using a broom missing half the bristles the sweeping ability will be extremely hindered. Therefore it is advised that you replace your toothbrush everytime you notice that the bristles have worn down too much to ensure that you are brushing effectively.

  • A common mistake is that people apply water to the toothbrush and toothpaste throughout brushing
  • By rinsing throughout brushing you are essentially diluting the toothpaste just like how you would dilute cordial in water. This is not want we want as this decreases the amount of fluoride available for the tooth to absorb and form a structure that can help protect against decay. As result it is advised that you rinse only at the start and only spit throughout brushing. Spit not rinse. This will avoid washing away the toothpaste.

  • A common mistake is that people use mouth immediately after brushing
  • Just like rinsing your mouth with water while you brush washes away the toothpaste so to is using mouthwash immediately after brushing. You often wash away the toothpaste. Most mouthwash has less fluoride then the toothpaste, therefore it is better to have the toothpaste there. It takes time for the fluoride to be absorbed by the tooth structure. The longer you wait to rinse the better chance the tooth can take up the fluoride and form a stronger tooth structure.

    Techniques

    Brushing Technique
    (click here to see the picture above)


    When brushing remember the acronym G.P.S. Which stands for Gums, Planning, and Slowly. Starting with gums hold the bristle brush at 45 degrees between the tooth and gums. Then flick up away from the gums. If you have a manual toothbrush do gentle circle motions. However, if you have an electric 2D or 3D toothbrush these perform the circlular motion for you so just gently hold it there at 45 degrees. The next step is to make sure you have a plan to prevent you from missing spots. Do not forget to do the tongue to remove bacteria that is living on it and help against bad breath. Next step is to brush slowly for at least 2 minutes twice a day. It is important that you do not do any harsh horizontal back and forth scrubbing strokes.


    Flossing Technique (Floss like a Boss)
    (click here to see the picture above)


    1. Wrap approximately 40cm of floss around your middle fingers. This allows your index finger and thumb to be used as controllers
    2. Use a gentle sawing motion to get the floss through where the two teeth meet. Then slowly perform an up and down motion
    3. Do not forget your gums. Gradually move towards the gums wrapping the floss around the tooth in a "C" shape moving up and down. Repeat this on the neighbouring tooth. You should feel the motion along and under your gums, but it should not be painful. It is like pushing up under the cuticle on your finger nails
    4. Use a fresh segment of the same floss for the next section of teeth. Floss daily. Night is a good option as you have more time and removes bacterial debris before you go to sleep.


  • Tip: Never "snap" floss into place as this often causes you to hit and hurt your gums.
  • Tip: If you are getting shredding or breaking of the floss it may be due to you have closely spaced teeth. Try dental tape or dental ribbon this is a stronger type of floss.
  • Tip: If your gums are not as firm or there are larger spaces between the teeth. Your oral health practitioner may recommend the use of interdental brushes. (click here to discover more about interdental brushes)
