How do I keep my teeth healthy?
You’ve probably heard how important it is to keep your teeth and gums clean. After all, healthy teeth help you to eat, speak, and smile. Research has also found that the health of your mouth is linked to your overall health. So, how can you be sure you’re cleaning your teeth the right way? And is there anything else you could be doing to maintain healthy teeth for life?
Here I’ll share four ways to take care of your teeth.
1. Brush your teeth correctly
Cleaning your teeth every day is an essential part of keeping your mouth healthy. It helps to remove tiny pieces of food and bacteria that build up on your teeth and gums throughout the day.
If you don’t clean your teeth properly, this bacteria can feed off the sugars you eat and coat your teeth in a sticky substance called plaque. Over time, the bacteria in plaque combines with sugars to produce acid that attacks the outer layer of your teeth (enamel). Certain types of bacteria can also irritate your gums which may lead to gum disease.
Follow these teeth care tips at home to clean your teeth properly.
- Brush your teeth twice a day, for two minutes. Once before bedtime and at one other time during the day – ideally in the morning.
- Use a pea-sized amount of toothpaste that contains 1,350 to 1,500 parts per million (ppm) fluoride. Fluoride is a mineral that helps to prevent tooth decay. Check the packaging to find out how much fluoride is in the toothpaste.
- Gently brush your teeth using small circular motions. Make sure to clean all surfaces of your teeth, your gumline and your tongue too. Try not to brush too harshly, because it can damage your gums.
- Spit instead of rinsing after you brush to avoid washing away the protective fluoride from your toothpaste.
- Choose a toothbrush that has a small head, soft or medium bristles, and both long and short bristles with round edges. An electric toothbrush may remove more bacteria than a manual one, but it’s more important to pick a brush you feel comfortable using and holding.
- Replace your toothbrush every three months, or sooner if the bristles start to become frayed. Worn bristles won’t clean your teeth properly.
- Don’t forget to clean in between your teeth at least once a day, using dental floss or tape, an interdental brush or water flosser.
- Wait one hour after eating or drinking acidic food and drinks before brushing, because the acids soften the outer layer of your tooth (enamel).
- Chew sugar-free gum after eating. It helps to produce saliva which cancels out acid and reduces your risk of tooth decay.
2. Clean in between your teeth
Flossing should also be a key part of your daily teeth cleaning routine. It removes food and plaque from the places your toothbrush can’t reach – like between your teeth and below your gumline. It can help to prevent tooth decay and promote healthy gums.
There are lots of tools to help you clean between your teeth, including:
- dental floss
- dental tape
- interdental brushes
- electric water flossers
It’s up to you which one you choose. But if you have advanced gum disease (periodontitis) and large gaps between your teeth and gums, a bigger interdental brush might work better for you. If you’re not sure which to use, ask your dentist for advice.
To clean in between your teeth correctly:
- floss at least once a day before brushing
- clean in between every single tooth, top and bottom, including behind your back teeth, and around any dental crowns, bridges or implants
- if you’re using an interdental brush, hold the handle and gently slide the floss or bristles between your teeth. Gently massage your gums whilst moving the bristles between your teeth. If you have to force it, choose a smaller brush
- if you’re using traditional floss or tape, take about 45cm of floss and hold 5cm of it taut between your thumbs and forefingers. Curve it into a c-shape, and gently rock it up and down between each tooth, scraping along the sides. Remember to keep the floss close to the tooth on each side and make sure it goes between your gum and tooth too
3. Make healthy lifestyle choices
Brushing and flossing aren’t the only things you can do to protect your oral health. The lifestyle choices you make every day also play a big role in keeping your teeth and gums healthy. Here are some simple habits that can make a difference.
Watch how often you eat sugary and acidic foods.
The sugar found in foods like sweets, pastries and biscuits feed off the bacteria in your mouth and make acids. Over time, these acids can damage your teeth and cause painful holes to form.
Acidic foods such as citrus fruits and fizzy drinks also wear away the outer layer of your teeth (enamel), causing tooth erosion.
So, try to reduce how often you eat sugary and acidic food and drinks. Keep them to mealtimes only and choose tooth-friendly foods like fruit, vegetables, and calcium-rich dairy foods, milk and water when you can.
Drink plenty of water.
Water plays a key role in keeping your mouth clean and fresh by rinsing away food particles and bacteria and neutralising acids. It also helps prevent dry mouth – a condition that can increase your risk of tooth decay and gum disease. Some water supplies are also fortified with fluoride, which is a natural mineral that helps to strengthen your tooth enamel and protect against cavities.
Reduce your alcohol intake.
Some alcoholic drinks and mixers are also acidic and high in sugar, which can increase your risk of tooth decay. They can also dry out your mouth, and when your saliva is reduced, bacteria can multiply, damage your gums and make your breath smell bad. Drinking alcohol also increases your risk of mouth cancer, and certain drinks, like red wine, can stain your teeth too. So if you do drink, it’s a good idea to cut back as much as possible to protect your oral health.
Stop smoking if you need to.
Smoking can stain your teeth, cause bad breath and leave a bad taste in your mouth. But it can also increase your risk of gum disease, tooth loss and mouth cancer. So if you do smoke, quitting is one of the best things you can do for both your oral and overall health.
4. Visit your dentist and hygienist regularly
It’s important to schedule regular check-ups with your dentist. Don’t wait until there’s a problem with your teeth to book an appointment. Your dentist will:
- check the health of your mouth, neck, jaws, teeth and gums
- find and treat any problems early
- give you personalised toothcare advice
Your dentist can let you know how often they’d like to see you.
It’s also a good idea to see a dental hygienist once or twice a year. They can give your mouth a professional deep clean and polish, remove plaque from hard-to-reach places and help prevent future dental problems.
