Children’s Oral Hygiene Instructions

  • Brush twice a day (after breakfast & before bed)
  • Adult supervision and/or assistance is required up to 9 years of age
  • Evening brushing is the most important time to brush
  • Use an adult toothpaste as soon as the child is able to spit out, from 6 years, or younger if your child is at high risk of getting decay
  • A smear of toothpaste across the width of the brush is sufficient
  • Mild mint adult toothpaste such as Sensodyne Pro Enamel are well tolerated by children
  • Encourage your child to look in the mirror when brushing & flossing
  • 2 minutes of brushing is advised, 3 seconds per tooth surface (each tooth has 3 brushing surfaces)
  • Floss once per day where the teeth are close together
  • Do not rinse out with water after brushing, just spit
  • If using a manual toothbrush, circular movements should be used over the front surfaces of the teeth
  • .05% Fluoride mouthwash (eg. Fluoriguard) is recommended for patients with braces or previous dental decay, over the age of 6 years. 10ml (2 teaspoons) for 1minute, at different time of the day to brushing (e.g. after the afternoon snack)
  • Your dentist will advise you of fluoride supplements if they are required
  • In the UK there is no fluoride added to the water hence instead of rinsing, spitting out toothpaste after brushing is recommended for extra protection

Preventing acid erosion

  • Keep acidic drinks to meal time (e.g. fruit juices, smoothies & carbonated drinks)
  • Use a straw where possible
  • Dilute Juices where possible
  • Do not brush teeth for 30min after consuming acidic drinks

Brushing advice

Diagram showing how to brush teeth

Brushing is the most effective way to remove harmful food and bacteria from your child’s teeth and gums. Brushing in a timely manner after eating prevents the food and bacteria from causing harmful acids which eventually break down the teeth.

As parents, you should clean your child’s teeth starting at birth. You can wipe your baby’s gum tissue following feedings with a wet washcloth. Once teeth have erupted, a soft baby toothbrush can be used with fluoridated toothpaste to brush your child’s teeth after mealtime. Children will need their parents help brushing their teeth until they develop the manual dexterity to brush their own teeth effectively.

Once your child can effectively spit out their toothpaste, you may begin using a fluoridated toothpaste to brush. You only need to place a pea-size amount of toothpaste on the brush and attempt to brush for 1-2 minutes. Singing songs or using a timer may help your child brush for the necessary length of time.

It is best to brush really well in the morning and again at night right before bedtime.

Remove plaque and bacteria by flossing

Flossing diagram

Flossing is the only method to remove plaque and bacteria from in-between the teeth that can not be reached by the toothbrush.  Floss is made of a synthetic cord which is inserted and moved in-between the sides of two adjoining teeth.  Flossing will remove the plaque and bacteria which cause harmful cavity-causing acids between the teeth.  It’s never too early to begin flossing your child’s teeth.  Flossing on a regular basis will increase blood supply to the gum tissue reducing the chances of developing cavities and gum-disease (gingivitis ie. bleeding gums, periodontal disease which can result in tooth loss).

Protect your child’s teeth with sealants

Sealants are a tough, plastic material that protect the grooved and pitted surfaces of the teeth, especially the chewing surfaces of the back teeth where most cavities in children are found.  Sealant application is quick, easy, and can be completed at your child’s initial or recall visit.  The tooth is first cleaned, then a sealant material is brushed onto the grooves of the tooth and hardened with a special curing light.  Sealants do not last forever and will need to be replaced as they wear away from the tooth surface.

Diet Advice

A balanced diet is important for your child’s overall health and dental health.  It is important to eat a variety of foods from each of the five major food groups: breads/grain products, fruits, vegetables, meat/poultry/fish, and milk/cheese/yoghurt.

Foods and drinks that are eaten as part of a meal cause less harm to the teeth.  More saliva is produced when eating a meal which helps wash foods from the mouth and helps lessen the harmful effects of acids on the teeth.

Children should eat healthy snacks in between meals such as cheese, raw vegetables, plain yogurt or a piece of fruit.  If less healthy snacks/drinks with a lot of sugar are introduced in between meals, there is a higher chance of the sugar causing tooth decay.  Each time you eat food or drinks with sugar, the teeth are attacked by acids for 20 minutes or more.  The Academy of Paediatrics recommends only 6-8 ounces (1 cup) of juice for children per day.  Juice should be given at mealtime only, and in between meals, if your child is thirsty, they should drink only water.

  • 3 main meals per day, and up to 2 snacks
  • Only Cow’s milk & still water should be drank between meals
  • Only drink water after the evening brushing
  • Sugary food is best given at the end of a meal
  • Ice cream and chocolate are better treats than hard/ sticky sweets

Sugary snacks to avoid…

  • Cakes
  • Dried fruits, fruit flakes and Yoyo Bears
  • Cereal bars i.e. nature valley
  • Biscuits
  • Sweets & chocolate
  • Flavoured crisps

And some healthy alternatives

  • Vegetable sticks/ dips/pita bread
  • Pretzels & bread sticks
  • Fresh fruit
  • Plain/ savoury rice cakes
  • Cheese with crackers
  • Yoghurts
  • Nuts (not recommended for patients with nut allergies)
  • Popcorn (unflavoured)
