You usually feel it before you see it. A hard little ridge on the lower gum during a feed. Or a spoon that clicks against something new. And then the thought that ruins the evening: was I supposed to have started brushing already?
Sort of, yes. Cleaning the mouth starts before the first tooth. The day that first white edge appears, you switch to a soft infant brush with a smear of toothpaste, twice a day, two minutes each time. None of it is hard. But the bedtime brush is the one that actually protects those teeth, and it is the first one families let go.
I have done this twice at home. At Janma I hear the same questions from hundreds of parents: how much toothpaste, what do I do about the teething pain, and does it really matter if it is only a milk tooth. So — the routine, properly.
At a glance
- Wipe the gums twice a day from the newborn weeks — it builds the habit long before there is a tooth to clean.
- The day the first tooth shows, move to a soft infant brush. Brush morning and last thing at night.
- A rice-grain smear of toothpaste under age 3; a pea-size blob from 3 to 6. Check your local water's fluoride before you choose.
- Nothing after the bedtime brush except water. No bottle in the cot, no feed-to-sleep once teeth are in.
- Book the first dental visit by the first birthday, or within six months of the first tooth.

Does oral care really start before the first tooth?
It does, though the reason surprises most people. Wiping a toothless gum removes almost no plaque. What it does is train. A baby who has had a clean finger or a soft cloth in their mouth since week three doesn't treat a toothbrush at seven months as an ambush. Months of wrestling, avoided.
How it goes. After the last feed of the day, wrap a clean, damp muslin square around your index finger and run it along the upper and lower gum pads, then gently over the tongue. Five seconds a side. Boiled-and-cooled water if your tap water is not drinking-safe. No toothpaste. No salt, no honey, no gauze soaked in anything. Our dentist's guide to cleaning baby gums before the first tooth has the technique in detail.
The routine, step by step
This is the version I would hand a tired parent. Print it. Stick it near the wash basin.
- Morning, after the first feed: sit your baby on your lap facing away, head resting back against your chest or forearm. Better than standing in front of them — you can see the whole mouth.
- Load the brush dry with a rice-grain smear of toothpaste. Don't wet the bristles first; wet bristles slide over a tooth instead of scrubbing it.
- Brush the outer surface of each tooth in small circles, gum line included. Ten seconds per tooth is plenty when there are only two.
- Brush the inner surface and the chewing tops — this is where we all get lazy, and where the first cavities turn up on lower molars.
- Wipe, do not rinse. Under age 3 a baby cannot spit on command. Wipe the excess foam off with a cloth and leave the thin film of paste on the teeth.
- Repeat as the very last thing before sleep — after the final feed, not before it.
- Water only afterwards. If your baby needs a bottle to settle, it holds water.
- Once two teeth touch, usually the upper front pair, add a gentle floss pass. A floss stick with a handle beats string with a squirming toddler.
Both sessions together: under three minutes. The hard part was never the technique. It is the 2am version of you, on the night the baby has already fallen asleep at the breast. Most families get this wrong for a few weeks and then find their rhythm. Brushing before the last feed beats not brushing at all, as long as that last feed is milk and not juice or sweetened water.
What to clean with, by age
| Age | Tool | Toothpaste |
|---|---|---|
| 0-6 months (no teeth) | Damp muslin or clean finger | None |
| First tooth to 18 months | Infant brush, small head, soft bristles (or finger brush) | Rice-grain smear |
| 18 months to 3 years | Toddler brush with a chunky handle | Rice-grain smear; teaching them to spit |
| 3 to 6 years | Child brush; child holds it, you finish the job | Pea-size, spit but do not rinse |
Fluoride is the one decision to check locally rather than copy from an American parenting site. Pockets of India carry naturally high fluoride in the groundwater — parts of Rajasthan, Telangana, Andhra, some Vidarbha districts near us in Nagpur — and a child there is already getting a dose from the drinking water. Elsewhere it runs the other way: low-fluoride water plus no fluoride toothpaste leaves teeth under-protected. Look up your area's water report, or just ask your paediatric dentist. We walk through the numbers in how much fluoride is actually safe for babies in India.
Teething: what helps, and what to leave on the shelf
Teething is uncomfortable. It is not an illness. Expect drool, chewing on everything, a grumpy evening, a night or two of broken sleep around each tooth. It does not cause high fever, diarrhoea or a full-body rash. If those show up, something else is going on, and it needs a doctor rather than a teether.
What genuinely helps, in the order I would try it:
- Counter-pressure. A clean finger rubbed firmly along the sore gum for thirty seconds. Free, instant, and better than most things you can buy.
- Cold, not frozen. A solid silicone teether out of the fridge. Never the freezer — rock-hard plastic on a swollen gum hurts more.
- Something to chew that cannot break. One-piece silicone or food-grade rubber. Check it for loose parts every week.
- A chilled steel tumbler, the oldest trick in an Indian kitchen. Babies love the cold rim. Supervise, obviously.
If the pain is clearly wrecking feeds and sleep, ask your paediatrician about an appropriate dose of paracetamol for your baby's weight. That is a conversation with a doctor, not a guess from a blog.
Skip these. Amber or wooden teething necklaces and bracelets — strangulation and choking risk, no evidence of benefit. Numbing gels containing benzocaine or lidocaine, unless a doctor has specifically prescribed one. Honey or sugar rubbed on the gums (honey is unsafe under 12 months, and sugar on erupting teeth is exactly what you are trying to avoid). Hard rusks and biscuits used as teethers — they turn to sugar paste against new enamel.
Which tooth is coming, and when it is due, changes what you clean and how. The sequence is more predictable than you'd expect, and we mapped it out in our baby teething timeline.
The teething side-effect nobody warns you about: drool rash
Six weeks of drool on a chin, in the neck folds, down along the collarbone. The skin goes red, chapped, sometimes weepy. Worse through a humid monsoon week. Worse again under a bib that has sat damp since lunch. Usually this is moisture and friction at work — but only a doctor can tell you what is going on with your baby's skin, so skin that weeps, crusts, spreads or simply is not settling should be seen by your paediatrician rather than treated at home.
Blot, do not wipe — patting with a soft cotton cloth spares skin that is already sore, where rubbing only inflames it. Change the bib the moment it feels damp; two dry bibs a day beat one soggy one. And put a thicker barrier product on before naps and bedtime, so the saliva sits on the balm instead of the skin. Look for fragrance-free, thick, with recognised barrier ingredients, no essential oils, and a texture that stays where you put it instead of sinking in within minutes. Reapply after you clean the area, once the skin is dry.
Habits that matter more than which toothpaste you buy
Parents agonise over brands, then miss what actually decides whether a three-year-old has cavities.
What happens at night. Saliva flow drops during sleep, so milk or juice pooling around the upper front teeth for hours is the single biggest risk to milk teeth. Feed, clean, sleep — in that order. If your baby feeds several times overnight, wipe the front teeth with a damp cloth when you can, and be strict about the morning brush.
What is in the mouth between meals. Constant sipping and nibbling keeps the mouth acidic all day. Proper meals, proper snacks, water in between. Kinder to enamel than a biscuit every hour, even a healthy one.
Comfort habits count too. Sucking is normal and most children give it up on their own, though a strong habit carrying on past the pre-school years can start to shift the front teeth. We compared the two options honestly in thumb sucking vs pacifier and what they do to baby teeth.
And yes, milk teeth matter. They hold space for the permanent set. They are how your child chews, and how they learn to say words clearly. Decay in them is painful, and sometimes needs treatment under sedation. Twenty teeth arrive over about two and a half years, and most stay until age 10 or 11. That is a long working life for something people call temporary.
When to see a dentist
Book a first check-up by your baby's first birthday, or within six months of the first tooth — whichever comes first. It is short: a look, and a chat about diet and brushing. It also makes every later visit easier. Go sooner if you notice any of these:
- White, chalky, brown or black marks on any tooth, especially near the gum line of the upper front teeth
- Gums that bleed easily, look swollen, or a lump or swelling on the gum
- A tooth that looks chipped, loose or discoloured after a fall
- Your baby refusing to feed or chew on one side, or crying during feeds without another explanation
- No teeth at all by around 15-18 months, or teeth erupting in an unusual position
- A high fever, spreading rash or loose stools blamed on teething — that needs a paediatrician the same day
- Drool rash that weeps, crusts, spreads beyond the chin and neck, or is not improving with barrier care — your paediatrician should look at it
If you want to know how that first appointment actually goes, and how to prepare a wary toddler for it, we wrote about when a baby's first dental visit should be in the Janma Journal.
For a drool-soaked chin and neck, what matters most is a barrier that is fragrance-free, thick enough to stay put, and free of essential oils. If you would like ours, the Hydra Healing Moisturizing Balm is what we use before naps and bedtime — it helps comfort dry, chapped skin and supports the skin's natural barrier.
In summary
- Wipe your baby's gums twice a day from the newborn weeks, then switch to a soft infant brush the day the first tooth appears.
- Brush morning and last thing at night with a rice-grain smear of toothpaste under age 3, wiping the foam away instead of rinsing.
- Give nothing but water after the bedtime brush — no bottle in the cot and no feed-to-sleep once teeth are in.
- For teething, use gum counter-pressure and a fridge-cold silicone teether; skip amber necklaces, numbing gels, honey and hard rusks.
- Book the first dental visit by your baby's first birthday, and go sooner for white or brown marks, swollen gums or a knocked tooth.
Frequently asked questions
When should I start brushing my baby's teeth?
The day the first tooth appears. Before that, wipe the gums twice daily with a damp muslin cloth to build the habit. Once a tooth is through, use a soft infant brush with a rice-grain smear of toothpaste, morning and last thing at night. No tooth is too small or too new to brush — decay can start on a tooth that has been in the mouth only a few weeks.
How much toothpaste should a baby use?
A rice-grain smear until about age 3, then a pea-size amount from 3 to 6 years. Under 3, babies cannot reliably spit, so wipe the excess foam away with a cloth instead of rinsing. Whether that paste should contain fluoride depends on your local drinking water, since parts of India have naturally high fluoride in groundwater — check with your paediatric dentist.
Does teething cause fever and diarrhoea?
No. Teething typically causes drooling, gum soreness, chewing on everything, and a couple of unsettled nights around each tooth. It does not cause high fever, diarrhoea or a widespread rash. Those symptoms usually mean an infection that happens to coincide with teething, and they should be seen by a paediatrician rather than treated with a teether or gel.
Is it bad to breastfeed my baby to sleep once teeth are in?
It is very common and not a reason for guilt, but it does raise cavity risk because saliva flow drops during sleep and milk sits around the upper front teeth. The practical fix is order: feed, then clean the teeth, then sleep. If overnight feeds continue, wipe the front teeth with a damp cloth when you can and be strict about the morning brush.
Do cavities in milk teeth actually matter if they fall out anyway?
Yes. Milk teeth hold space for the permanent set, and most stay in the mouth until age 10 or 11. Decay in them is painful, can affect chewing and speech, and sometimes needs treatment under sedation in a small child. An infection in a milk tooth can also damage the permanent tooth developing underneath it.
What can I put on my baby's chin for drool rash from teething?
Blot the area dry with a soft cotton cloth rather than wiping, change damp bibs as soon as they feel wet, and apply a thick, fragrance-free barrier balm before naps and bedtime so saliva sits on the product instead of the skin. Avoid essential oils and heavily fragranced creams. If the rash weeps, crusts or spreads, have a doctor look at it.
