Children's teeth: what actually matters
Reviewed by a registered dentist · Last reviewed 13 August 2026
Most childhood dental problems in India come down to three things: brushing that starts too late, fluoride toothpaste used in too small a quantity or not at all, and sugar taken too frequently rather than in too great an amount. Get those right and the rest is largely routine.
Why milk teeth matter
“They'll fall out anyway” is the most expensive sentence in paediatric dentistry. Decayed milk teeth cause pain, infection and missed school. Infection at the root of a milk tooth can damage the permanent tooth developing directly beneath it. And milk molars hold space: lose one early and the neighbouring teeth drift into the gap, so the permanent tooth has nowhere to come through — which is how a ₹1,000 filling at six turns into ₹40,000 of orthodontics at fourteen.
Brushing, by age
| Age | What to do |
|---|---|
| Before teeth | Wipe the gums with a clean damp cloth after feeds. |
| First tooth – 3 years | Brush twice daily with a soft baby brush and a rice-grain smear of fluoride toothpaste (1000 ppm or more). |
| 3 – 6 years | Pea-sized amount, twice daily. Teach spitting; no rinsing afterwards. |
| 6 – 8 years | Child brushes, but an adult brushes again or closely supervises. Manual control isn't there yet. |
| 8+ years | Independent, with periodic checking. Add flossing where teeth touch. |
Two rules that make a disproportionate difference: brush last thing at night after which nothing but water is given, and spit, don't rinse — rinsing washes away the fluoride you have just applied.
Bottle decay — the one to prevent
Putting a child to bed with a bottle of milk, juice or sweetened water bathes the upper front teeth in sugar all night, when saliva flow is at its lowest. The result is early childhood caries: brown or black upper front teeth in a two- or three-year-old, frequently requiring treatment under general anaesthesia. Prolonged on-demand night breastfeeding after teeth erupt carries a similar risk if the teeth are not cleaned.
Prevention is simple: no bottle in bed, water only after the last brush, move to a cup from around twelve months, and never dip a soother in honey or sugar.
Sugar: frequency over quantity
A child who eats a whole chocolate bar at once has one acid attack. A child given two biscuits every hour has eight. In practice that means: sweets with meals rather than between them, juice and sweet drinks limited and finished quickly rather than sipped, and plain water between meals. Watch the ones that don't look like sweets — flavoured milk, sweetened curd, biscuits, dried fruit, ketchup and many “health” drinks.
Habits
- Thumb sucking and soothers. Normal in infancy. It is worth stopping by around age three to four, and certainly before the permanent front teeth arrive at six or seven, after which it can push teeth forward and create an open bite. Encouragement and reward charts work far better than scolding or bitter paints.
- Mouth breathing and snoring. Worth mentioning to a doctor — enlarged adenoids or tonsils affect facial growth and dryness increases decay.
- Grinding at night. Very common in children and usually harmless; it typically resolves on its own.
- Nail biting and chewing pencils. Chips enamel and strains the jaw joint.
The first dental visit
By the first birthday, or within six months of the first tooth. The purpose is not treatment — it is prevention advice and, crucially, familiarity. A child whose first experience of a dental chair is a friendly count of their teeth is vastly easier to help at eight than one whose first visit is an emergency extraction. Take them along to your own appointments too.
Please never use the dentist as a threat (“behave or I'll take you to the dentist”), and don't promise “it won't hurt” — if it does, you have lost their trust. Say the dentist will count and clean the teeth, and leave it at that.
Treatments you may be offered

|---|---|---|
| Fissure sealant | Thin coating in the deep grooves of new molars. Cheap, painless, highly effective. | ₹400 – ₹1,200 per tooth |
| Fluoride varnish | Applied two to four times a year for children at higher risk. | ₹500 – ₹1,500 per visit |
| Filling in a milk tooth | Yes, worth doing — see above. | ₹500 – ₹2,000 |
| Pulpectomy and crown | Root treatment for a badly decayed milk molar, capped to keep it functional. | ₹2,000 – ₹6,000 |
| Space maintainer | Holds the gap when a milk molar is lost early. | ₹2,000 – ₹6,000 |

When to see someone promptly
- Any facial swelling, or fever with dental pain — same day
- Brown or black marks on the front teeth of a toddler
- A tooth knocked out, loosened or pushed in
- A permanent tooth erupting behind a milk tooth that hasn't fallen out
- Pain that keeps a child awake
- An ulcer or lump lasting more than two weeks
Where an online consultation fits
Well, for parents. Most of what determines a child's dental future is technique and habits, both of which can be assessed and corrected over video — the right toothpaste amount, brushing position, feeding and snacking patterns, thumb-sucking strategy. It is also a low-stress way to have marks on your child's teeth looked at before deciding whether a clinic visit is urgent.
Under Indian law and our own policy, a consultation for a child must be booked and attended by a parent or lawful guardian — see our teleconsultation policy.

Book a consultationFrequently asked questions
Is fluoride toothpaste safe for a toddler?
Yes, in the right quantity. A rice-grain smear under three and a pea-sized amount from three to six gives the protective benefit while keeping swallowed fluoride low. Toothpaste with no fluoride offers very little protection against decay.
My child's permanent tooth came in behind the milk tooth.
Common with lower front teeth, sometimes called shark teeth. If the milk tooth is loose, encourage wiggling and it usually falls out. If it is firm after a few weeks, a dentist should remove it so the permanent tooth can move forward.
Are the new front teeth meant to be yellower?
Yes. Permanent teeth are naturally more yellow than milk teeth, and next to remaining white milk teeth the contrast looks stark. It is normal and needs nothing.
White or brown patches on new adult teeth?
Often dental fluorosis from too much fluoride during tooth formation, which is common in parts of India with high fluoride in groundwater. Usually cosmetic only. Worth having assessed, as it can also be an early decay lesion or a developmental defect.
