What Is Teething?
The tooth crown forms in the jaw during pregnancy; root development then pushes the crown upward through the gum tissue over weeks. The inflammation and pressure on surrounding tissue is what causes pain — not the tooth "cutting" through as a blade would.
Teething is a process that unfolds over 2–3 years (first tooth to final molar), not a single event. The 20 primary teeth erupt in a predictable sequence, though the timing varies by several months between children [1][2].
Signs and Symptoms of Teething
Excessive Drooling
The most consistent sign. Saliva production surges as the tooth approaches the gum surface, increasing from around 3 months and peaking at eruption. A drool rash on cheeks and chin is common.
Swollen, Red Gums
The gum tissue directly over the erupting tooth becomes visibly puffy and darker pink. You may see the white tip of the tooth before it breaks through.
Fussiness & Irritability
Gum pressure increases overnight (more blood flow when horizontal) and during quiet periods. Most acute in the 3–5 days surrounding the tooth breaking through.
Chewing on Hands & Objects
Counter-pressure on the gums provides temporary relief. A baby chewing on everything with swollen gums is almost certainly teething.
Ear Pulling
The ear canal and gums share nerve pathways, so discomfort can radiate toward the ear. Ear pulling with fever, however, may indicate an ear infection.
Rosy Cheeks
Local inflammation can cause a flush on one or both cheeks, on the side of the erupting tooth.
Disrupted Sleep
Night discomfort peaks 1–3 days before a tooth breaks through. See the sleep section below for guidance.
Baby Teething Age Timeline and Eruption Chart
Lower central incisors are usually first. Sequence is not always symmetric between children.
| Tooth | Upper Jaw | Lower Jaw |
|---|---|---|
| Central incisor | 8–12 months | 6–10 months |
| Lateral incisor | 9–13 months | 10–16 months |
| First molar | 13–19 months | 14–18 months |
| Canine (cuspid) | 16–22 months | 17–23 months |
| Second molar | 25–33 months | 23–31 months |
The first tooth to appear in most babies is the lower central incisor at 6–10 months, with upper central incisors following at 8–12 months. The upper lateral incisors typically erupt before the lower laterals — the sequence is not always symmetric or predictable.
A first tooth at 3 months or at 12 months are both normal variants. Absence of any teeth by 18 months warrants a mention to your paediatrician.
If your baby was born prematurely, use corrected age for teething timing in the first 2 years, exactly as with developmental milestones [1][2].
Teething Fever vs. Real Fever: What's Actually Teething?
Teething does not cause fever above 38°C (100.4°F). A temperature at or above this threshold is a sign of illness — not teething — and warrants a call to your paediatrician. Similarly, teething does not cause diarrhoea, vomiting, or a significant runny nose. These symptoms during the teething window are coincidental, not causal.
Macknin et al. (2000) followed 125 children through 475 tooth eruptions and found the only symptoms with statistically significant elevation during teething were drooling, gum rubbing, sucking, irritability, wakefulness, and ear rubbing. Fever above 38°C did not reach statistical significance [6].
| Symptom | Teething? | If present, consider |
|---|---|---|
| Gum swelling and redness | ✅ Yes | Normal — tooth approaching surface |
| Excessive drooling | ✅ Yes | Normal — peak around eruption |
| Fussiness / irritability | ✅ Yes | Peaks 3 days before/after tooth breaks |
| Rosy cheeks | ✅ Yes | Local inflammation |
| Low-grade temp (< 38°C) | ⚠️ Possible | Some elevation possible; above 38°C is illness |
| Fever ≥ 38°C (100.4°F) | ❌ No | Call paediatrician — viral or bacterial illness |
| Diarrhoea | ❌ No | GI illness — call paediatrician if persistent |
| Vomiting | ❌ No | GI illness — call paediatrician |
| Runny nose / congestion | ❌ No | Respiratory illness — monitor |
| Ear pulling with fever | ❌ No | Ear infection — call paediatrician |
| Loss of appetite with fever | ❌ No | Illness — call paediatrician |
Safe Baby Teething Relief: What Works and What to Avoid
✓ Safe Teething Relief Options
Chilled Teethers (Not Frozen)
The most effective physical relief. Chilling (not freezing — frozen teethers can damage gums) provides counter-pressure and numbing. Silicone preferred over rubber; avoid liquid-filled teethers. Always supervise.
Chilled Damp Cloth
A clean facecloth dampened with water and chilled 15–20 minutes. Give to baby to chew directly — texture and cold both provide relief. Machine wash after each use.
Gum Massage
Use a clean finger (or silicone fingertip brush) for gentle counter-pressure. 1–2 minutes is usually enough — one of the most effective techniques for the 3 AM moment.
Teething Toys & Rings
Choose BPA-free silicone. Avoid amber beads, painted or varnished wood, and teethers with small detachable parts. Should be easy to grip and not fit entirely in the mouth.
Age-Appropriate Pain Relief
For moderate-to-severe discomfort, infant paracetamol or ibuprofen (from 6 months) at the weight-appropriate dose, used short-term. Follow packaging dosing or your paediatrician's guidance. Never use aspirin.
Distraction & Comfort
At the acute moment, distraction (rocking, singing, a walk outside) is as effective as physical relief for many babies. Discomfort is intermittent — peaks of 20–30 minutes, not hours.
✗ Avoid — With Reasons
| Product | Risk | AAP Position |
|---|---|---|
| Benzocaine gels (Bonjela, Anbesol) | Methaemoglobinaemia risk — reduces blood's oxygen-carrying capacity | Not recommended under 2 years (FDA 2018) |
| Amber teething necklaces/bracelets | Strangulation and choking hazard; no clinical evidence of efficacy | Explicitly advised against |
| Choline salicylate gels (Teejel) | Reye's syndrome risk in children | Not recommended under 16 years |
| Frozen teethers or ice cubes | Gum damage from extreme cold | Use chilled, not frozen |
| Herbal/homeopathic teething tablets | FDA warnings for belladonna-containing tablets — variable dosing, seizure risk | Avoid |
| Teething biscuits under 6 months | Not appropriate before solids introduction | Not before 6 months |

Track Symptoms Free →Feeding During Teething
Teething changes the oral environment in ways that directly affect feeding behaviour. Understanding what is happening makes it easier to respond.
🍼 Bottle Feeding
- The nipple's seal applies gum pressure — some babies refuse feeds or take shorter, more frequent ones
- Offer a chilled teether 5–10 minutes before the feed
- Try a different nipple shape (wider base vs. standard)
- Smaller, more frequent feeds beat pushing a full feed
- 6+ wet nappies per 24 hours is the hydration reassurance signal
🤱 Breastfeeding
- Most biting happens at the end of a feed, once active swallowing slows
- Watch for the swallowing pause and unlatch before the bite
- If a bite occurs: unlatch calmly (pull baby toward the breast, not away), say "no" neutrally, end the feed for 1–2 minutes
- Avoid a strong reaction — it can reinforce biting
- Teeth do not make breastfeeding impossible — keep going
🥄 Solids
- Textured or crunchy foods may be refused — more chewing pressure on inflamed gums
- Offer softer foods at room temperature or slightly chilled
- Cold purées, yoghurt, chilled cucumber spears are often accepted
- Temporary — resolves within 3–5 days of the tooth erupting
| Feeding Type | Teething Impact | Response |
|---|---|---|
| Bottle feeding | Gum pressure → shorter feeds or refusal | Pre-feed teether; different nipple; smaller feeds |
| Breastfeeding | Biting risk post-feed | Unlatch at swallowing pause; neutral bite response |
| Solids | Refusal of textured foods | Soft, cool alternatives; temporary phase |
Teething and Sleep: Why Nights Get Harder
Teething is one of several overlapping causes of disrupted infant sleep — not the only one. Understanding which part is teething and which part is a sleep habit or developmental regression helps target the response correctly.
Gum inflammation increases when lying horizontal (greater blood flow to the area). The teething baby who seemed fine all day and is screaming at midnight is not performing — the discomfort is genuinely worse when horizontal.
🦷 Teething Waking
Baby is distressed, gums are visibly swollen, waking is acute (30–60 minutes), an age-appropriate remedy partially relieves it, resolves within 3–5 days of the tooth erupting.
🧠 Sleep Regression Waking
Baby is alert and wakeful rather than distressed, no visible gum changes, waking is frequent and persistent across weeks, a settling association is the more likely driver.
A baby in the 6–8 month window may be simultaneously experiencing the 8-month sleep regression, teething (first or second incisors), and separation anxiety. Distinguishing them is hard but important: treat the teething symptoms (gum massage, chilled teether before bed), address the sleep schedule (wake windows), and don't introduce new settling associations during the teething peak that you will need to undo after the tooth erupts.

Oral Hygiene After the First Tooth
The first tooth is the start of the oral hygiene routine — not a future milestone. Tooth decay can affect primary teeth; early childhood caries is the most common chronic disease of childhood, and primary teeth hold space for permanent teeth.
- Use a soft infant toothbrush (finger brush or dedicated infant brush)
- Brush twice daily — after the morning feed and last thing before bed
- Use fluoride toothpaste from the first tooth — a grain-of-rice amount, not a smear (AAP 2023)
- Do not rinse after brushing — spit only, or let baby swallow the trace amount
Bottle and nursing hygiene: do not put baby to sleep with a milk bottle — pooling milk around the teeth causes rapid decay (bottle caries). If baby falls asleep at the breast after a night feed, gently wipe gums with a damp cloth before returning to the crib if possible.
First dental visit: the AAP and ADA both recommend the first dental visit at the eruption of the first tooth, or by 12 months — whichever comes first. Primary care paediatricians can apply fluoride varnish from the first tooth at well-child visits [1][2].
When to Call Your Paediatrician
- Temperature ≥ 38°C (100.4°F) — this is illness, not teething
- Diarrhoea, vomiting, or significant nasal congestion alongside teething symptoms
- Ear pulling accompanied by fever (possible ear infection)
- No teeth by 18 months
- Extreme swelling, bruising, or a bluish fluid-filled lump over the gum (eruption cyst)
- Baby not eating or drinking for more than 24 hours due to mouth pain
- Signs of mouth infection: pus, extreme redness, persistent high fever
This checklist is a reference guide, not a diagnostic tool. If you are concerned at any point, contact your paediatrician — there is no such thing as an unnecessary call about a sick baby.
Frequently Asked Questions
Most babies cut their first tooth between 4 and 7 months, with the lower central incisors typically appearing first. However, some babies begin teething as early as 3 months and as late as 12 months — both are within the normal range. A first tooth before 3 months or an absence of any teeth by 18 months warrants a mention to your paediatrician.
The most consistent teething signs are excessive drooling, swollen or red gums, fussiness, chewing on hands and objects, ear pulling, and rosy cheeks on the side of the erupting tooth. Disrupted sleep is also common in the 1 to 3 days before a tooth breaks through the gum. Teething does not cause fever above 38°C, diarrhoea, or vomiting.
No. Teething does not cause a fever above 38°C (100.4°F). A low-grade temperature elevation (below 38°C) may occur during the teething window, but a true fever indicates illness — not teething. If your baby has a temperature at or above 38°C alongside teething symptoms, call your paediatrician. The two can occur at the same time coincidentally, as the teething window overlaps with the period when maternal antibody protection declines.
Yes. While the most common age for the first tooth is 4 to 7 months, teething can genuinely begin at 3 months. A 3-month-old with excessive drooling, chewing on fists, and swollen gums may be in the early teething window. The first tooth may not appear for several more weeks — the symptoms often precede eruption by 4 to 8 weeks.
The acute discomfort associated with each tooth typically peaks in the 3 to 5 days surrounding the tooth breaking through the gum surface — roughly 1 to 2 days before and 2 to 3 days after. Discomfort before that window is usually mild. Molar teething tends to cause more prolonged discomfort (5 to 7 days per molar) due to the larger surface area pushing through gum tissue.
The second molars (erupting at 23 to 33 months) are generally the most uncomfortable, followed by the first molars (13 to 19 months). Molars have a significantly larger surface area pushing through the gum compared to incisors, and they erupt during a developmental stage when toddlers can express distress more intensely but cannot always communicate the source.
The first molars typically erupt between 13 and 19 months (upper) and 14 to 18 months (lower). The second molars erupt between 25 and 33 months (upper) and 23 to 31 months (lower). Molar teething is often more intense than incisor teething — the symptoms and management approach are the same, but the duration and severity are typically greater.
No. Research does not support a causal link between teething and diarrhoea or significant nasal discharge. These symptoms during the teething window are coincidental — either a separate viral illness or, in the case of mild nasal discharge, a result of increased saliva production. If your baby has diarrhoea, vomiting, or significant nasal congestion, treat it as a possible illness and call your paediatrician if symptoms persist.
Teething symptoms are: swollen red gums, excessive drooling, gum-chewing, rosy cheeks, irritability, and mild sleep disruption. Illness symptoms are: fever ≥ 38°C, diarrhoea, vomiting, significant nasal congestion, loss of appetite beyond 24 hours, or extreme lethargy. If you are unsure, always call your paediatrician — teething should not make a baby truly unwell.
The safest teething relief options are: chilled (not frozen) silicone teethers, gum massage with a clean finger, a chilled damp cloth, and age-appropriate infant paracetamol or ibuprofen (from 6 months) at the weight-appropriate dose when discomfort is moderate to severe. Benzocaine gels, amber teething necklaces, homeopathic teething tablets, and frozen teethers are not safe for infants.
Gum inflammation increases in the lying-flat position, so discomfort typically peaks at night. Expect 1 to 3 nights of disrupted sleep around each tooth eruption — particularly the molars. Treat gum discomfort with a chilled teether or gum massage before the bedtime routine. Avoid introducing new settling associations during the teething peak (feeding or rocking to sleep) that will need to be addressed after the tooth erupts.
Begin brushing at the eruption of the first tooth. Use a soft infant toothbrush and a grain-of-rice amount of fluoride toothpaste — twice daily, after morning feed and last thing before bed. Do not rinse after brushing. This is the current AAP recommendation (updated 2023) — the previous guideline of fluoride-free until 2 years has been revised. The first dental visit should be at the first tooth or by 12 months.
