Comment brosser et prendre soin des dents de votre enfant

Why looking after your child’s teeth is important

We need our teeth to be able to chew food and eat, but there are many other reasons why looking after your children’s teeth is important.

Our mouths are full of bacteria, which when not kept under control, can lead to la carie dentaire, gum disease and oral infections. Your mouth is also the entry point to your digestive and respiratory tracts - so bacteria has the potential to cause other problems too. Very rarely it can go to your heart and cause endocardite infectieuse.

Brushing your child’s teeth and encouraging them to look after their teeth as they get older can keep bacteria under control. Getting your child in the habit of good oral care can also help to prevent health problems in adulthood too, including heart disease¹.

Karen Coates, a registered dental nurse and content specialist for the Oral Health Foundation: “Tooth brushing should be part of a child's personal hygiene routine, just like washing their hands, face, and hair and having a bath.”

Your baby or toddler might not like brushing their teeth to begin with, but there are ways to encourage them. Getting them used to it will help it become part of their routine as they get older.

“There are lots of toothbrushes available for children, bright colours, colour-change ones, favourite character brushes too,” says Coates. “Letting your child choose their own toothbrush will often help to encourage them to brush. Remember, praise and encouragement will often get results.”

Children under 3

You should start brushing your baby's teeth as soon as they get their first tooth. This is usually around six months, but can be earlier or later. You should brush your child’s teeth for two minutes with a smear of fluoride toothpaste twice a day - last thing at night and once during the day.

Although you should brush their teeth for them, you can give them a toothbrush to chew on to get them used to the texture of it. The toothpaste should contain at least 1,000 ppm of fluoride - the label should tell you how much it contains - unless a dentist advises otherwise.

“When your child is a baby or toddler, the best way to clean their teeth is to sit them on your knee, facing away from you,” advises Coates. “Cradle their chin in your hand so that you can reach the upper and lower teeth easily.”

Coates says to use small, circular motions to clean all the surfaces of the teeth whether they are a baby or a small child.

“Don’t forget to clean the gums and behind the teeth,” she says. “You should not let your child swallow the toothpaste. Instead, they should spit out the excess. Do not let them rinse out their mouth, as this will wash all the fluoride off the teeth.”

Children aged 3 to 6 years

You should continue brushing your child’s teeth between the ages of 3 and 6, but they can have a go themselves if you’re watching them. Brushing should happen twice daily for two minutes, at the start of the day and before bed.

“As they grow older, you can let them have a go at brushing their own teeth, after you have finished. You should supervise brushing until the age of 7 years old,” says Coates. “Once they are over 3 years old, they should use a pea-sized smear of toothpaste that contains between 1350 to 1500 ppm of fluoride.”

Make sure they spit out the toothpaste - and avoid swallowing it - but don’t rinse it. Rinsing the mouth means the fluoride won’t work as well.

Children aged 7 and over

“Children aged 7 and over should be able to brush their own teeth, but it's still a good idea to watch them to make sure they brush properly and for about 2 minutes,” says Coates.

You should make sure they brush twice daily with fluoride toothpaste and avoid rinsing after spitting out the excess.

How to find a dentist

Taking your child to the dentist regularly will help keep their mouth, teeth and gums healthy. Currently, it is recommended that children go for a check-up once a year. When your child is born, it’s a good idea to find a local dental practice that offers NHS services - there will likely be a waiting list. You'll need to register your child before making any appointments.

Many people are having trouble finding a dentist. More than two-thirds of children (70%) in England did not see an NHS dentist in the 12 months to December 2020². You can either join a waiting list, look for a different dentist who is taking on NHS patients, or be seen privately. You have to pay more for private dentistry but how much depends on the practice. It's important to visit the dentist as often as you can to prevent your child from getting tooth decay.
