Dental issues are some of the most common health problems in New Zealand^ . They can significantly impact your overall wellbeing, which is why it's important to look after your oral health. Part of this means finding a dentist who's right for you, but there are still steps you can take at home to keep your teeth and gums healthy.

How to care for your smile isn't always obvious, though. As a provider of dental services in New Zealand, Bupa knows that there are many dental related questions that may not be so straightforward. With over 20 Bupa owned dental clinics around New Zealand, they've gathered the most frequently asked questions to help 'straighten things out' for our community.

What kind of toothbrush is best?

Whether you choose a manual toothbrush or an electric one, it's important to use one with a small head. This will help you reach your back teeth, especially the areas between the tongue and lower molars. Stiff, hard bristles can damage your teeth and gums, so use one with soft bristles. One study found that electric toothbrushes are better at removing plaque and bacteria due to the rotating action of the head.

How often should you change your toothbrush?

When your toothbrush starts to look a little frayed (often around three months after purchasing), it's time to get a new one. This helps make sure that your teeth are properly cleaned. Plus, bacteria can build up in and on the bristles.

How often should you brush your teeth?

The New Zealand Dental Association recommends brushing your teeth twice daily with fluoride toothpaste. Brush after breakfast and dinner (or before you go to bed). Remember to wait about 20 minutes after eating since your enamel is a little weaker after consuming certain foods (especially acidic ones).

How long do I need to brush my teeth for?

Spend at least two to three minutes brushing your teeth to help remove food particles and plaque build-up. To ensure you're brushing your teeth correctly, follow these five steps:

1. Place your toothbrush at a 45 degree angle to your gums.

2. Move the brush back and forth in short strokes.

3. Cover all areas of the teeth and gums by dividing the upper and lower teeth into front, left and right areas. Brush each area with gentle, tooth-wide strokes.

4. Brush all the surfaces of all your teeth, including the inner areas. Use the tip of the brush for the inner front tooth surfaces.

5. Don't forget to brush the top surface of your tongue.

How should I floss?

Flossing removes plaque from between your teeth and around the gumline. You should aim to floss at least once a day. Follow these five flossing tips for healthy teeth and gums:

1. Use enough floss so you can hold the ends comfortably in your hands (about 45 cm). Wind the floss around both middle fingers and support it across your thumbs and index fingers.

2. Insert the floss gently with a side-to-side motion. Hold your thumbs and index fingers closely together to guide the floss between each tooth.

3. Curve the floss into a C-shape around the tooth at the gum line. This will help clean the 'neck' of the tooth.

4. Scrape the floss up and down moving the floss away from the gum line. Use a clean part of the floss with each new tooth.

5. Remember to floss the back side of the last tooth.
