Baby Teething and Oral Health: Signs, Care Tips & When to See a Dentist

By Dr. Neha Singh · Medically reviewed by Dr. Reji Moideen · 25/02/2026 · Children's Dentistry in Dubai

Baby teething usually starts around 6 months, and the classic signs are drooling, sore gums, chewing on everything, fussiness, and mild sleep disruption. It is a normal developmental phase, not an illness, so real fever, diarrhoea, or a genuinely unwell baby point to something other than teething. The bigger message for parents is that oral health begins before the first tooth appears, so gentle gum cleaning, safe soothing, and a first dental visit by age one all belong in this stage. This guide walks through the signs, safe care, and the exact moments to call a dentist or a doctor.

Teething is one of the biggest milestones in a baby’s first year, and also one of the most confusing. A baby who slept beautifully last week suddenly turns drooly, cranky, and desperate to gnaw on a fist. Parents almost always ask the same three things: Is this normal? Is it really teething? And when should I actually worry? At Mint Dental Care we tell families the same thing every time. Baby oral health should start early, not after all the teeth have arrived.

The first baby teeth usually erupt at around 6 months, though some babies begin earlier and others later, and most children have all 20 primary teeth by about age 3. Knowing what is normal, what genuinely helps, and when a dental visit makes sense can make this whole stage calmer for baby and parent alike.

When do babies start teething?

Most babies start teething around 6 months, but there is a wide window of normal. Some get their first tooth before 4 months, others not until after their first birthday. The lower front teeth (the central incisors) usually come through first, followed by the upper front teeth, and the rest arrive gradually over the next two years or so.

This variation matters because parents often worry when teeth do not appear “on schedule.” In most cases a few months either way is completely normal. What counts far more than the calendar is your baby’s comfort, keeping the gums and new teeth clean, and starting dental care the moment teeth begin to show.

6 to 10 months: lower central incisors (bottom front two)
8 to 12 months: upper central incisors (top front two)
9 to 16 months: the lateral incisors either side of the front teeth
13 to 19 months: first molars
16 to 23 months: canines
23 to 33 months: second molars, completing the 20 primary teeth

What are the common signs of teething?

The most common teething signs are increased drooling, sore or tender gums, chewing on fingers and objects, irritability, and disturbed sleep. Symptoms vary a lot from baby to baby. Some children barely notice a new tooth, while others get noticeably uncomfortable for a few days before it breaks through.

Alongside the classics, some babies develop a mild rash on the chin or cheeks from constant dribbling, a single flushed cheek, or a very slight rise in temperature that is not a true fever. You may also see extra biting, gum rubbing, and a stronger urge to chew than usual.

Here is the point that saves a lot of worry. Teething does not usually cause a true fever, significant diarrhoea, or a genuinely sick child. Mayo Clinic and Cleveland Clinic both note that while teething can nudge body temperature up slightly, a reading of 38°C (100.4°F) or higher should never be brushed off as “just teething.” Marked diarrhoea, lethargy, dehydration, or a baby who seems unwell needs medical attention, not reassurance.

What teething discomfort actually feels like

Most teething discomfort comes from pressure as the tooth pushes up through the gum. The gum often looks a little swollen, red, or irritated right where the tooth is erupting, and you can sometimes feel a hard bump under the surface. Babies respond by rubbing their gums, biting toys, and wanting extra cuddles. This tends to come and go in waves over a day or two rather than staying intense, which is why it helps to think of teething as a normal phase and not an ongoing illness.

How can I safely soothe a teething baby?

The safest teething remedies are also the simplest. Gently rub your baby’s gums with a clean finger, a cool spoon, or a moist gauze pad to ease soreness. A clean, firm rubber teether helps too, especially chilled in the fridge rather than frozen solid.

Rub the gums with a clean finger or damp gauze for 1 to 2 minutes
Offer a fridge-cold (never frozen) firm rubber teether
Wipe drool often with a soft cloth to protect the skin on the chin
Give extra comfort and contact, which genuinely reduces fussiness
For babies already on solids, cool soft foods can feel soothing under supervision

Heavy drooling can irritate the skin around the mouth, so frequent gentle wiping and a barrier cream if needed keeps that rash at bay. The main focus stays on comfort, supervision, and gentle gum care. If your baby is truly miserable, your pharmacist or paediatrician can advise on infant paracetamol, but medication is a backup, not a first move.

What should I avoid during teething?

Avoid numbing gels, homeopathic teething tablets, and teething jewellery, because these carry real safety risks for infants. Not every product sold as a “teething remedy” is safe, and some have caused serious harm.

Benzocaine and lidocaine gels: the FDA warns against these for infants and young children
Homeopathic teething tablets: linked to safety concerns and best avoided
Amber teething necklaces and any teething jewellery: the FDA reports choking and strangulation injuries, including deaths
Rock-hard frozen teethers: chill them, do not freeze them solid, as they are too harsh on sore gums

The AAPD also advises against topical anaesthetic gels for teething because of potential toxicity in babies. When in doubt, stick to the simple, physical soothing methods and skip anything you swallow or wear.

Does oral health really start before the first tooth?

Yes, cleaning your baby’s mouth should begin before any teeth are visible. One of the most overlooked parts of infant oral health is that care starts in the first days and weeks of life, not once teeth appear.

Wipe your baby’s gums with a clean, moist gauze pad or soft washcloth after feeds. This removes plaque and, just as usefully, gets your baby comfortable with having their mouth cleaned, which makes toothbrushing far easier later. The habit of early cleaning is exactly why we stress that baby teeth care matters more than parents expect, long before the smile is full of teeth.

Once the first tooth erupts, the routine shifts from gum wiping to actual brushing. Teeth can start to decay as soon as they appear, so waiting “until there are more teeth” is the wrong approach. Early habits set the tone for everything that follows.

How do I brush baby teeth properly?

As soon as the first tooth comes through, brush twice a day with a small, soft-bristled baby toothbrush. For children under 3, use only a smear of fluoride toothpaste about the size of a grain of rice.

Brush every morning and again before bed, so the last thing on the teeth is fluoride, not milk
Use a rice-grain smear of fluoride toothpaste until age 3, then a pea-sized amount
Parents should do the brushing or closely supervise it, since young children cannot brush thoroughly alone
When two baby teeth touch, start gently cleaning between them

Guidance from the ADA, AAPD, and CDC supports this small fluoride amount, which balances cavity protection with safe use in babies. These steps look tiny, but they are among the most effective ways to prevent early childhood cavities. If brushing is turning into a nightly battle, our team can show you positioning tricks at your child’s first dental visit that make it far less of a struggle.

Why do baby teeth matter if they fall out anyway?

Baby teeth matter a great deal, even though they are temporary. Primary teeth help children chew, speak clearly, smile with confidence, and hold space so the adult teeth erupt in the right position.

Early decay is not harmless. It can affect feeding, sleep, comfort, and long-term oral development, and a badly decayed baby tooth can damage the permanent tooth forming beneath it. In the CDC’s 2024 surveillance findings, more than 1 in 10 children aged 2 to 5 had at least one untreated cavity in their primary teeth. When decay does take hold, prompt treatment for cavities in baby teeth protects both the tooth and the child’s comfort.

Parents lower the risk by cleaning early, using fluoride toothpaste in the right amount, limiting sugary drinks, and never putting a baby to bed with a bottle of milk, formula, or juice. Frequent, prolonged contact with sugary liquids around sleep is one of the biggest drivers of early childhood decay.

When should a baby first see a dentist?

A baby’s first dental visit should happen when the first tooth appears, and no later than the first birthday. This is the standard recommendation from the ADA and AAPD. It feels early, but that is the point. Early visits prevent problems and build a positive relationship with dental care before there is any pain or fear.

At that first appointment, the dentist checks how the teeth and gums are developing, looks for early signs of decay, and discusses fluoride, bottle use, pacifiers, and thumb-sucking. It works like a “well-baby checkup” for the mouth. If you are weighing up where to go, our guide to choosing the best pediatric dentist in Dubai covers what to look for, and you can read more about when your child should first see the dentist so the timing is clear.

When to see a dentist sooner than age one

Do not wait for the first birthday if something looks wrong. Book a visit sooner if you notice white chalky spots, brown spots, visible holes, a chipped tooth, mouth swelling, unusual sores, or if your child has had a fall involving the mouth or teeth. Early cavities often begin as white, chalky patches, and any trauma or swelling deserves a professional look. It is also worth calling if the daily oral care routine has become impossible or you are unsure the teeth are erupting normally.

How do I tell teething apart from real illness?

The simplest rule is that teething makes a baby uncomfortable, but it should not make a baby look genuinely ill. If your child seems truly unwell rather than just grumpy, treat it as illness first and teething second.

Call your doctor if your baby has a true fever, diarrhoea, marked lethargy, dehydration, trouble waking, or breathing difficulty. Guidance is especially firm that any baby under 3 months with a temperature over 38°C (100.4°F) needs urgent assessment. Parents hear “it’s just teething” far too often, and that phrase has masked real infections before. When in doubt, trust your instincts and get advice.

Frequently Asked Questions

What is the difference between teething symptoms and actual illness in infants?

Teething symptoms are localised and mild: drooling, sore gums, chewing, extra fussiness, and slightly disturbed sleep, sometimes with a very small rise in temperature. Actual illness usually brings a true fever of 38°C (100.4°F) or higher, significant diarrhoea, vomiting, poor feeding, lethargy, or a baby who simply seems unwell. If your child looks genuinely sick rather than just uncomfortable, assume it is not teething and speak to a doctor.

Can teething cause a fever?

Teething can cause a very slight rise in temperature, but it does not cause a true fever. A reading of 38°C (100.4°F) or higher should be treated as a possible infection, not dismissed as teething, especially in babies under 3 months who need urgent assessment.

How long does teething pain last for each tooth?

Discomfort for a single tooth usually lasts a few days, often flaring in the day or two before the tooth breaks through the gum and easing once it appears. It tends to come and go in waves rather than staying constant, so long stretches of intense distress point to something other than teething.

Is it normal for teething to disrupt sleep?

Yes, mild sleep disruption around a new tooth is common and normal. Extra soothing during the day, a fridge-cold teether before bed, and keeping the usual routine steady all help. If your baby is waking in real distress night after night, or has other symptoms, it is worth ruling out illness.

Does teething cause diarrhoea?

No, teething does not cause true diarrhoea. Extra saliva can loosen stools slightly, but frequent watery diarrhoea, especially with fever or signs of dehydration, is a sign of illness and should be checked by a doctor rather than blamed on teething.

When should I take my baby to the dentist?

Bring your baby in when the first tooth appears and no later than the first birthday, then sooner if you spot white or brown spots, holes, a chipped tooth, swelling, or after any mouth injury. Early visits are preventive and set up a lifetime of healthier smiles.
