Toddler with toothebrush

They’ve got a tooth and it looks super cute. But hang on, now you need to look after it. Here’s our guide…

There’s no need to wait for your baby to have a full set of gnashers. Start looking after them as soon as the first one appears by brushing twice a day, just like you do your own. It is important to keep their teeth healthy from day one. Hopefully, your baby will think it is all a new, fun game you are playing.

Did you know?

Milk teeth play an important role in the alignment and spacing of your little one’s permanent teeth (Community Practitioner, 2011). Think of them as important placeholders.

Baby and toddler toothbrushes

At first it might be easier to clean their teeth with a piece of clean cloth on your finger (Family Lives, 2018). Or a handy finger toothbrush, usually made of silicone, might be easier to control to begin with.

When you do buy a proper toothbrush, get one specifically for young children, with a small head and soft bristles (Family Lives, 2018). Change it every three months or sooner – when the bristles begin to splay or fall out (Family Lives, 2018). Babies have a tendency to chew, chew, and chew the head of a toothbrush, so you might end up replacing it far more often than that.

Manufacturers of electric toothbrushes advise parents that these are only suitable once your child is three years old. So stick to a manual one before then.

Baby and toddler toothpaste

When it comes to brushing your child’s teeth, pick a specific kids’ toothpaste, as adult toothpastes might contain too much fluoride. It should still contain at least 1,000ppm (parts per million) of fluoride though as this helps prevent and control decay (NHS Choices, 2018).

"Use a tiny smear of toothpaste for babies and toddlers up to three years old."

Increase this once they are between three and six years old to a pea-sized amount (NHS Choices, 2016).

How to brush their teeth, and how often

  • A helping hand: For babies, sit them on your knee and rest their head against your chest while you brush their teeth. When they’re older, stand behind them and tilt their head backwards.
  • Brush their teeth at least twice a day: Just before bed and at any other time. Gradually build up how thoroughly you do it, so eventually you’re getting all of the surfaces of their little teeth, for two minutes ideally.
  • Brush the teeth in small circles, covering all the surfaces: And encourage them to spit the toothpaste out afterwards, just like they see their mum and dad doing. There's no need to rinse with water though, as this will just wash away the fluoride.
  • Watch for them licking or eating toothpaste from the tube: It’s best to always supervise brushing when they’re little, probably even until they’re around seven years old. (NHS Choices, 2016, 2018).

My baby won’t have their teeth brushed – help…

Lots of children aren’t that keen on teeth brushing. Here are some handy tips:

  • Don’t stress: If tooth brushing might not go quite to plan – some babies aren’t that receptive to having their teeth brushed at first – don’t worry too much. The important thing is that you start to make it part of their routine.
  • Let them hold the toothbrush: If they feel more in control of things, they might be more into it.
  • Make it into a game, or brush your own teeth at the same time: Then they can copy you – this can work from a really young age.
  • Watch out for their wriggling: Supervision is key, a baby and a stick of plastic in their mouth could all end in tears if they fall forwards, so keep a close eye (NHS Choices, 2018).

When do I need to take my baby to the dentist?

You get free NHS dental treatment for children so that’s a bonus. Take them with you when you go for your own dental appointments. That way they get used to the idea and then sign them up for their own appointments, as soon as they have some teeth. The sooner they get used to it, the more comfortable they’ll be at the dentist (NHS Choices, 2018).
