Many parents believe children should start brushing when they get “many teeth” or when they start school.
That is actually too late.
Tooth decay in children is now one of the most common childhood diseases—even more common than malaria and cough in some communities. The surprising part? It often begins before the child turns two years old.
So let’s clear the confusion.
👶 When Should Brushing Really Begin?
A child should start oral cleaning as soon as the first tooth appears.
Yes—even just one tiny tooth!
Usually, the first tooth erupts at 6 months of age (sometimes earlier, sometimes later). From that moment, bacteria can attach to the tooth and start causing decay.
You should still clean the baby's mouth before teeth erupt.
What to do before teeth come out:
After breastfeeding or formula feeding:
-
Wrap a clean soft cloth or gauze around your finger
-
Dip it in clean, lukewarm water
-
Gently wipe the baby’s gums, tongue, and cheeks
This removes milk residue and prevents bacteria from building up.
🪥 What To Use When the First Tooth Appears
Do NOT use a normal adult toothbrush.
Use:
-
A soft baby toothbrush (very small head)
-
Or a silicone finger brush
Toothpaste?
Yes—but only a very tiny amount.
For children under 3 years: Use fluoride toothpaste the size of a grain of rice.
(Too much toothpaste is actually harmful because children swallow it.)
How Many Times Should a Child Brush?
Twice daily:
1. Morning—after breakfast
2. Night—before sleeping (MOST IMPORTANT)
The night brushing is critical because saliva reduces during sleep. That means bacteria attack teeth faster at night.
If you must choose one brushing, choose the night brushing.
Common Mistakes Parents Make
1. Letting children sleep with milk or juice
This is the biggest cause of early tooth decay.
When a child sleeps with:
-
milk bottle
-
breastfeeding throughout the night
-
sweetened drinks
Sugar remains on the teeth for hours, allowing bacteria to produce acid, which leads to the formation of holes.
This is called decay from using a baby bottle.
2. Allowing children to brush alone too early
Children cannot brush properly until about 7–8 years old.
Parents must assist with brushing—especially night brushing.
A beneficial rule:
If a child cannot tie shoelaces properly, they cannot brush teeth correctly.
3. Giving sweets frequently
It is not the quantity of sugar that damages teeth.
It is the frequency.
Eating sweets 6 times a day is worse than eating many sweets once and brushing afterward.
When Should a Child First Visit the Dentist?
The first dental visit should be: The first dental visit should occur by the age of 1 or within 6 months after the appearance of the first tooth.
Avoid visiting the dentist when experiencing pain.
Early visits:
-
prevent fear of dentists
-
detect problems early
-
save money (treatment is cheaper early)
