Tiny teeth need looking after from the very first one — but it doesn’t have to be a battle. Here’s a calm, practical guide to when to start, how much toothpaste to use, how to make brushing actually happen, and when to see a dentist.
When should I start brushing my toddler’s teeth?
Start as soon as the first tooth appears — often around 6 months, though it can be earlier or much later, and that’s completely normal. You don’t need to wait for a mouthful of teeth.
- Brush twice a day: once in the morning and once last thing before bed.
- The bedtime brush matters most, because saliva (which protects teeth) slows down overnight.
- Before that first tooth, you can gently wipe your baby’s gums with a clean damp cloth if you like, though it isn’t essential.
Even though baby teeth eventually fall out, they still count. They help your child eat and talk, and they hold space for the adult teeth coming later. Looking after them now sets up good habits for life.
How much toothpaste should I use?
Less than most people expect — and the amount changes with age:
| Age | Toothpaste amount |
|---|---|
| First tooth to age 3 | A tiny smear (grain of rice) |
| Age 3 to 6 | A pea-sized amount |
A few simple rules go with it:
- Use a fluoride toothpaste — fluoride is the main thing that protects against decay. Check the label or ask your dentist about the right level for your child’s age.
- Use a small, soft-bristled brush made for babies or toddlers.
- After brushing, encourage your child to spit out the toothpaste rather than rinse with water. Leaving a little behind lets the fluoride keep working.
- Brush gently in small circles, covering the front, back and tops of every tooth.
Always supervise — and do the brushing yourself for younger toddlers, since their hands aren’t ready to do a thorough job until around age 6 or 7.
How do I make tooth brushing actually stick?
This is where most parents struggle, and a wriggling, clamped-shut toddler is completely normal. Consistency matters far more than a perfect brush every single time. A few things that help:
- Make it routine. Same time, same order, every day. Predictable is calming.
- Let them join in. Give them a brush to hold while you do the real brushing, or take turns (“your go, then my go”).
- Use a mirror. Many toddlers love watching their own mouth.
- Sing or use a timer. A two-minute song or a brushing app turns it into a game.
- Brush together. Toddlers copy you — let them see you brushing your own teeth.
- Try a different position. Some toddlers do better lying down with their head in your lap, so you can see clearly and reach every tooth.
On the hard days, a quick gentle brush is better than none. Stay calm, keep it light, and don’t turn it into a power struggle — the goal is a child who grows up thinking brushing is just a normal, no-drama part of the day.
What about teething pain and sore gums?
If your toddler is grumpy about having their mouth touched, teething might be part of it. Sore, swollen gums can make brushing feel uncomfortable. You can still brush gently — keeping the area clean actually helps — but be extra soft around any tender spots.

When should my toddler first see a dentist?
Sooner than many parents expect. General guidance is to book a first dental visit by your child’s first birthday, or within about six months of that first tooth coming through.
These early visits are short and gentle. The dentist usually:
- Checks that teeth and gums are developing well.
- Shows you the best brushing technique for your child’s age.
- Talks through diet, especially sugary drinks and snacks.
- Helps your toddler get used to the chair so future visits feel normal.
After that, regular check-ups (often every six to twelve months, or as your dentist advises) keep things on track. Going early and often means the dentist becomes a familiar, friendly face rather than something scary.
A few habits that protect little teeth
Brushing is the main event, but a few everyday choices help just as much:
- Watch the sugar, especially sticky snacks and sweet or fizzy drinks. Water and plain milk are the best everyday drinks.
- Avoid sugary drinks in a bottle at bedtime — milk or juice pooling around teeth overnight is a common cause of decay.
- Don’t share spoons or “clean” a dummy in your own mouth, which can pass on decay-causing bacteria.
- Move from bottle to cup around the first birthday where you can, which is gentler on teeth.
Start small, stay consistent, and keep it calm. A toddler who brushes twice a day with a little fluoride toothpaste — even imperfectly — is off to a great start.
