Looking after your child’s teeth doesn’t need to be complicated. By building a consistent routine and using the right technique, you can effectively remove plaque — the sticky film of bacteria that forms on teeth and can lead to decay and gum issues if left behind.

1. Brush Morning and Night
Children should brush their teeth twice each day for a full two minutes.
Once in the morning
Once before going to sleep
Using a timer, app, or electric toothbrush with a built-in timer can help ensure they brush for long enough.
2. Choose Fluoride Toothpaste
Fluoride plays an essential role in protecting teeth against cavities.
Under age 3: apply a thin smear
Age 3 and over: use a pea-sized amount
Always supervise to ensure the correct quantity is used.
3. Spit, Don’t Rinse
After brushing, children should spit out excess toothpaste without rinsing.
Avoiding rinsing helps keep fluoride on the teeth for longer, giving it more time to strengthen enamel.
4. Cover Every Surface
Effective brushing means cleaning all areas of every tooth:
Outer (front-facing) surfaces
Inner (back-facing) surfaces
Chewing (biting) surfaces
Encourage a consistent brushing pattern to avoid missing any spots.
5. Focus on the Gum Edge
Angle the toothbrush slightly towards the gums.
This technique helps clean along the gum line — an area where plaque commonly builds up.
6. Selecting the Right Toothbrush
Both manual and electric toothbrushes can clean teeth well when used properly.
Look for:
Soft bristles
A comfortable grip
A head size suitable for a child’s mouth
Replace brushes or heads every 2–3 months, or sooner if the bristles become worn.
7. Mouthwash – Is It Needed?
Mouthwash is not a necessity for children.
If used:
Choose one containing fluoride
Use it at a separate time from brushing (e.g. after lunch)
This prevents washing away the protective fluoride from toothpaste.
8. Adult Supervision
Young children need help with brushing until they develop good coordination — typically around 7–8 years old.
Until then, an adult should assist or closely supervise to ensure teeth are cleaned properly.
Building Lifelong Habits
Establishing good brushing habits early on lays the foundation for strong, healthy teeth into adulthood.
