You're changing a nappy at 2am, your finger brushes the lower gum, and there it is — a sharp little ridge that wasn't there last week. Your baby's first tooth. Most babies get their first tooth between 6 and 10 months, almost always a bottom front one, and it needs gentle cleaning from the very day it appears. No lathered-up toothpaste. No fancy gadget. No dental appointment that same afternoon. Thirty seconds, twice a day, and a bit of a plan. That's the whole job.
Plenty of anxious parents have sat across from me holding a wide-awake, drooling, faintly miserable baby, certain they've got something wrong. Almost always, they haven't. So here's what's normal, what to do about it, and the couple of things actually worth watching.
At a glance
- First tooth typically arrives at 6-10 months — but anywhere from 4 to 12 months is normal.
- The two bottom front teeth (central incisors) come first, then the top front pair.
- Start cleaning the day the tooth appears: a soft cloth or tiny brush, twice a day.
- Use a rice-grain smear of fluoride toothpaste from the first tooth — not a pea-sized blob.
- Book the first dental visit by your baby's first birthday, or within 6 months of the first tooth.
When does the first tooth actually come in?
It varies — a lot — and the window that counts as normal is genuinely wide. Six to ten months is the middle of the pack. But I've seen healthy babies cut a tooth at four months, and others still all gums at their first birthday. A late first tooth, on its own, is rarely a worry. Teething timing runs in families, so if you or your partner were late, chances are your baby will be too.
The order, though, is fairly predictable, and it helps to know what's coming:
- Bottom front two (central incisors) — usually first, around 6-10 months.
- Top front two — next, often 8-12 months. These are the ones parents notice in photos.
- The teeth on either side (lateral incisors) — roughly 9-16 months.
- First molars, canines, then second molars — rolling in through the second and third year.
Most children have their full set of 20 milk teeth by around age 3. You don't need to log it like a spreadsheet — just knowing the front-bottom-first pattern means nothing catches you off guard.
What teething actually looks like
Teething gets blamed for a lot it isn't guilty of. The real, common signs: more drool than usual, chewing on anything within reach, sore or slightly puffy gums, some fussiness, and a few broken nights around each tooth. A mild rise in temperature can come with it. But a proper fever (over 38°C), diarrhoea, vomiting, or a cough is not teething. That's an illness that happened to land at the same time, and it needs looking at on its own.
One thing that catches a lot of Indian parents off guard: teething and nappy rash often turn up together, and there's a real, if roundabout, link worth understanding. If you're seeing both at once, I've written about it in Diaper Rash and Teething: Are They Actually Linked?
How should you actually clean that first tooth?
The moment a tooth breaks through, it can pick up plaque and decay — yes, even in a baby living mostly on milk. Milk, breastmilk included, carries sugars, and a tooth left bathed in it overnight is exactly how early childhood caries gets going. So cleaning isn't optional. How you clean, though, is a real choice, and the best answer shifts as your baby grows.
| Method | Best for | Honest pros & cons |
|---|---|---|
| Clean damp cloth or gauze | The very first tooth or two; also cleaning gums before teeth arrive | Gentle, cheap, always to hand. Wraps around your finger for control. But it can't clean between teeth and does little once molars arrive. |
| Silicone finger brush | Nervous first-timers who want more grip than a cloth | Soft bumps massage sore gums and clean better than cloth. Easy for you to feel what you're doing. Bristles are short, so it's a stepping stone, not a long-term brush. |
| Tiny soft-bristle baby toothbrush | Once a few teeth are through (roughly 9-12 months onward) | Cleans best, reaches gum line and grooves, and builds the lifelong habit early. Needs a steady hand and a calm-ish baby. Replace it every 2-3 months or when bristles splay. |
Fluoride toothpaste: how much, and from when?
This is where most of the confusion sits, so let me put it plainly. Use a smear of fluoride toothpaste — about the size of a grain of rice — from the very first tooth, twice a day. Fluoride is what actually protects a new tooth from decay; a non-fluoride "training" paste tastes nice and does little else. That rice-grain amount is small enough to be safe even though your baby will swallow most of it. You only move up to a pea-sized amount around age 3, once they can spit.
Soothing sore gums on the fussy days
On the chewy, miserable days, the safest things are also the plainest. A clean teether chilled in the fridge — the fridge, not the freezer, because rock-hard is too much — gives firm counter-pressure that genuinely helps. So does a clean finger rubbed along the gum, or a cool spoon. Extra cuddles and patience beat anything on a shelf. Through our Nagpur summers, I'd keep two or three teethers rotating in the fridge so there's always a cool one within reach.
Habits that quietly protect that new tooth
A first tooth is a clean slate — the small routines you set now decide how easy the next few years feel.
- No bottle in the cot. A baby falling asleep with a bottle of milk (or worse, juice or sweetened water) pools sugar around the new teeth all night. If a bottle is part of settling, follow it with a quick wipe or brush.
- Nothing sweet on a dummy. Honey, sugar, jaggery water on a soother — all of it feeds decay. Honey also isn't safe before age 1 for other reasons.
- Start a sippy cup around 6 months. Moving off bottles as they approach one year is gentler on teeth and bite.
- Your mouth to theirs. The bacteria that cause decay are passed on — sharing spoons or "cleaning" a dropped dummy in your own mouth transfers them. Use clean water instead.
When to see a dentist
Book that first dental visit by your baby's first birthday, or within six months of the first tooth — whichever comes first. Mostly it's a friendly look and a chat about brushing, but it catches problems early and gets your child comfortable with the chair. Outside the routine visit, see a dentist or paediatrician sooner if you notice:
- White, brown or pitted patches on a new tooth — these can be early decay or enamel defects.
- No teeth at all by around 15-18 months (worth a check, usually just late).
- Bleeding, very swollen or pus-filled gums, or a tooth that looks knocked out of place after a fall.
- A true fever, poor feeding, or lethargy you're blaming on teething — have a doctor rule out infection.
The part worth holding onto: looking after a first tooth is genuinely simple. A soft cloth or small brush, a rice-grain smear of fluoride, twice a day, and a chilled teether for the rough nights. Do that, keep all-night milk off the teeth, and you've handed your child a real head start — long before they can say the word "dentist."
In summary
- Expect the first tooth at 6-10 months, usually a bottom front one — 4 to 12 months is all normal.
- Clean it twice a day from day one, ending with the bedtime brush after the last feed.
- Use a rice-grain smear of fluoride toothpaste, and don't rinse it away with water.
- Soothe sore gums with a fridge-chilled teether — skip amber necklaces and unprescribed teething gels.
- Book the first dental check-up by your baby's first birthday, and keep milk bottles out of the cot.
Frequently asked questions
At what age does a baby's first tooth come in?
Most babies get their first tooth between 6 and 10 months, though anywhere from 4 to 12 months is normal. It's almost always one of the two bottom front teeth. A late first tooth on its own is rarely a concern — timing runs in families. If there are still no teeth by around 15-18 months, mention it to your dentist or paediatrician for a simple check.
Do I need to clean my baby's first tooth?
Yes, from the very day it appears. Even a baby mainly on milk can get decay, because milk and breastmilk contain sugars that sit on the tooth. Clean it twice a day with a soft damp cloth or a small baby toothbrush and a rice-grain smear of fluoride toothpaste. The most important clean is the last one before bed, after the final feed.
How much toothpaste should I use for a baby?
Use a smear about the size of a grain of rice, and choose a fluoride toothpaste — fluoride is what actually protects a new tooth from decay. This tiny amount is safe even though your baby will swallow most of it. Don't rinse with water afterwards; letting the little bit of fluoride linger is the point. Move up to a pea-sized amount around age 3, when your child can spit.
Is teething causing my baby's fever?
Probably not. Teething can cause drooling, gum soreness, chewing, fussiness and a slight rise in temperature. But a true fever above 38°C, diarrhoea, vomiting or a cough is not teething — it's a separate illness that happened to arrive at the same time. Don't dismiss a genuinely unwell baby as "just teething"; have a doctor check them.
Are amber teething necklaces safe?
No. Amber teething necklaces carry a real strangulation and choking risk and have no proven benefit, which is why dentists and paediatricians advise against them. Never tie anything around a baby's neck for teething. Safer options that genuinely help are a clean teether chilled in the fridge, a clean finger or cool spoon to rub the gums, and extra cuddles.
When should my baby first see a dentist?
Book the first dental visit by your baby's first birthday, or within six months of the first tooth appearing — whichever comes first. It's mostly a gentle look and a chat about brushing, but it catches problems early and helps your child feel at ease with the dentist. Go sooner if you spot white or brown patches on a tooth, or swollen, bleeding gums.
