How to look after your teeth and gums

20 March, 2020

Brushing your teeth

For many of us, brushing our teeth is second nature and we often don’t spend much time analysing our technique. As your dentist has probably told you, the way you brush your teeth is very important.

When should you brush your teeth?

The Australian Dental Association (ADA) recommends brushing your teeth for two minutes morning and night.

What toothbrush should you use?

ADA recommend using a soft-bristled toothbrush with a small head and a flexible neck. You can also use an electric toothbrush if you find that easier. Some of the electric toothbrushes come with a two-minute timer which makes it easier to brush for the right amount of time. There’s a lot of electric toothbrushes on the market and if you need help choosing one, read the Choice guide on how to buy the best electric toothbrush.

What toothpaste should you use?

While the choice of toothpastes available in a supermarket can be overwhelming, the ADA recommends choosing a toothpaste that contains fluoride. You only need a pea-sized amount of toothpaste.

Your brushing technique

The ADA recommend not pressing too hard on your teeth as your brush. If you press hard, you increase your risk of wearing away the enamel on your teeth and damaging your gums. A good sign that you’re pressing too hard is if your bristles start to wear out well before the three-month mark.

It's a good idea to start brushing your teeth from the gumline at a 45-degree angle, and brush in a circulation motion. If you have an electric toothbrush, it’s a good idea to slowly move the brush along your teeth, following the curve of your gums.

Many of us are in the habit of rinsing our mouths after we finish brushing our teeth, but ADA recommend we finish with just a spit.

When should you replace your brush?

You’ll need to replace your toothbrush when the bristles start to spread and get wider than the width of the base of the brush or every three months, whichever comes first. You should also replace your brush after you’ve been sick.

Flossing your teeth

Flossing should also be a part of your dental hygiene routine. You should floss once each day, either morning or night, and you should floss for two minutes. The ADA recommends the following steps:

  1. 1. Wind about 45 cm of floss around your middle fingers and rest it across your thumbs and index fingers

  2. 2. Insert the floss gently between your teeth and clean between them using an up and down motion

  3. 3. Slide the floss under the little collar of each gum and then back up the other side

You can also ask your dentist to show you the best way to floss next time you go in for check-up.

Regular dental check-ups

It’s important to see your dentist regularly as they can often spot the early signs of tooth decay. They can also advise you if your brushing or flossing technique isn’t cleaning your teeth effectively. You should check with your dentist how often you should have a dental check-up. Even if you don’t have any symptoms or tooth pain, it’s still important to regularly see a dentist.

Lifestyle changes to protect your teeth

As well as brushing and flossing your teeth, there are also lifestyle measures you can take to improve your dental health.

Stop smoking

It probably doesn’t come as a surprise, but smoking can cause staining and discolouration of your teeth. It’s the nicotine and tar in the cigarettes that causes this to happen. As well as a range of other health problems, smoking can also reduce the blood flow to your teeth and gums and contribute to teeth loss. Smoking also increases your risk of developing oral cancer and decreases the production of saliva which helps to protect your teeth from decay.

Reduce your alcohol intake

Regularly drinking too much alcohol can also result in damage to your teeth. The sugar and acidity in alcohol can contribute to erosion of your teeth. If you need help with managing your alcohol intake, read our article on alcohol and your health.

Limit sugary foods and drinks

Consuming added sugar in foods and drinks is one of the main causes of tooth decay. It’s not only chocolate and sweets that contain high levels of sugar, there’s also a lot of sugar in highly processed carbohydrate foods such pastries and some pastas. You should also particularly avoid soft drinks, sports drinks and fruit juices as these are all high in sugar.

I joined as a CBHS member in 1978. Through many health events and challenges CBHS has always been there for me and my family. Their exceptional service over this time has always been appreciated.

I've not long joined CBHS from another fund, but so far I've been impressed by the super helpful and friendly staff, the higher claim limits and rebates at a very competitive premium, and how easy it is to lodge manual claims through the app. Thanks CBHS - you've won me over! 😃

I have been with CBHS since I began at CBA 15 years ago...Now I have three beautiful children, one who has a disability. Our top extras cover has been really essential for his early intervention. I do love the ease of claiming online.

What Our Members Think

I am relatively new to CBHS and am loving it already. I worked for a CBA subsidiary a long time ago but was still eligible to join. So much better that the for-profit funds - our premium is only a little more and we pay a lower co-contribution and get great benefits. I am loving the massage rebate for my partner and gym rebate for me!

I'm extremely happy with CBHS! I have been a customer for about six years. I think the price is reasonable. And i would refer you to my family and friends any day. Thank you CBHS!!!

What Our Members Think

Love CBHS as I never have to doubt that they've got my back when I need it. Been through other insurers who have limited options or limits, yet cost the same or more.
