Children and teenagers: looking after their teeth

As children become older, they have to take responsibility for their own actions, and choosing what they want to eat and drink is part of that. They are given a huge choice in shops, at school and even at friends' houses.

Educating your child to understand the difference between a healthy drink or snack choice can make all the difference.

Drinks

Water and milk are the best drinks for children. Water will hydrate them giving them enough energy to function normally. If your child does not like water, then try a small amount of no added or sugar free squash. 

Children often think that they need sports drinks to either do sport or to look cool!

Sports drinks may seem like a healthy choice, but most are still high in sugar. Some sports drinks contain between 56 and 76 grams of sugar. This is equal to about 14 to 19 teaspoons. 

There is also a large amount of caffeine in energy drinks. A 250ml energy drink can contain almost the same amount of caffeine as a double espresso.  

Be aware of flavoured milk or milkshakes as these will contain high levels of sugar. Some milkshakes contain between 30-80 grams of sugar. This is equal to 7-20 teaspoons of sugar.

Toothbrushing

From the age of 7 children should have the manual dexterity to be able to brush their teeth effectively themselves, but they may still need a bit of encouragement and guidance from an adult. 

These simple steps will ensure your child’s teeth stay healthy:

  • Avoid sugary foods and drinks between meals and within one hour of bedtime
  • Brush for about two minutes with fluoride toothpaste.
  • Brush before bed and at one other time during the day. 
  • Wait at least 30 minutes after eating before brushing teeth
  • Use a fluoride toothpaste containing 1450ppm of fluoride (look for this on the ingredients of the packaging)
  • Use a pea size amount
  • Brush for 2 minutes
  • Use a small, medium textured brush or an electric toothbrush. It can be difficult sometimes in shops to find a toothbrush which has a small head but it is worth searching around as larger toothbrushes really do not clean effectively.
  • Spit the toothpaste out but don’t rinse after brushing
  • Visit the dentist regularly

Electric toothbrushes/battery toothbrushes 

Many young people prefer them and they often do a better job than using a large manual brush. However it is a good idea to know how to use them as the technique is slightly different from using a manual brush. 

Challenges around teeth brushing 

Some young people may experience challenges around brushing their teeth. At this age, they are developing their independence. This could mean that they feel like don't want to brush their teeth only because their parent told them to. They may forget to brush their teeth if they are doing something they find more entertaining.  

To encourage teeth-brushing in teens, you can: 

  • establish a consistent routine. 

  • encourage them to set themselves reminders to brush their teeth, such as notifications on their phone. This could give them a sense of independence by taking control of their oral health, without being told what to do.  

  • remind your teen that good oral health can boost their confidence and help make good first impressions with their peers.  

Some young people may experience sensory or motor issues which can make it uncomfortable to brush their teeth. Read about some tips and tricks that may help your young person.  

Braces and retainers 

Some young people have braces or retainers. It’s important to include them in the daily oral hygiene routine.  

Mouthwash

Mouthwash contains a lot less fluoride than toothpaste – usually about 225ppm.  

  • If you use mouthwash, use it during the day between meals. 
  • Try to avoid using it straight after brushing as you do not want to wash away the protective fluoride from the higher concentration of fluoride on your teeth from your toothpaste. 
  • Mouthwash can be used from age 8.

Free sugar

Eating too much sugar is bad for your teeth and can make you gain weight too, but we need to be especially careful of consuming too much free sugar. Free sugar is any sugar that’s not inside the cells of the food we eat, and this includes any that’s added to a food or drink.

Examples of foods that contain free sugars:

  • Soft drinks (a 330ml can of cola contains 35g of free sugar)
  • Fruit juices (150ml of fruit juice contains 12g of free sugar)
  • Smoothies 
  • Milk Shakes 
  • Dried Fruits e.g. raisins 
  • Honey
  • Syrup
  • Jam
  • Chocolate spread
  • Chocolate (a standard chocolate bar contains 25g of free sugar)
  • Biscuits
  • Pastries 
  • Cakes

Foods that contain natural sugars but no free sugars: 

  • Fruit –whole fruit which is fresh, canned or frozen ( but not dried or processed such as found in juice or smoothies. See below)
  • Vegetables  
  • Milk 

When fruit is made into juice, the sugar is released from the cells and becomes free sugar, while the fibre in the fruit is lost. This makes it easier to consume a lot of sugar without meaning to. 

The government recommends free sugars make up no more than 5% of your daily calories. This means:
 

Age Maximum amount of free sugar per day Number of teaspoons
Children under the age of 4 None 0
Children aged 4 to 6 19g 5
Children aged 7 to 10 24g 6
Children aged over 11 and adults 30g 7

Try to keep sugary food and drinks to mealtimes, as it is not how much sugar, but how often sugar is consumed that damages teeth.

Healthy snacks, such as fresh fruit, fresh vegetables, rice cakes, hummus, cheese and plain popcorn are a perfect option.
