Teething and Baby Sleep

Why teething disrupts sleep — and how to help your baby through it

One night your baby is sleeping through. The next night they are up every hour, crying, chewing on everything, and drooling like a faucet. Teething is one of the most common sleep disruptors in the first two years — and one of the hardest to manage because you cannot explain to a baby why their mouth hurts.

When Do Babies Start Teething?

Teething timelines vary widely, but here is the general pattern:

4–7 months: Lower central incisors (bottom front teeth) usually appear first. This is often the most uncomfortable wave because it is the first one.
8–12 months: Upper central incisors (top front teeth) come in. Many babies also get the lateral incisors (the teeth next to the front ones) during this period.
13–19 months: First molars arrive — these have broader surfaces pushing through the gums and can be surprisingly painful.
16–22 months: Canines (eye teeth) emerge.
25–33 months: Second molars — often the last and most uncomfortable wave before the full toddler set is complete.

That is 20 baby teeth in total, and every single one can disrupt sleep for a few days (or sometimes weeks) as it breaks through the gum.

How to Tell If Teething Is the Culprit

Teething symptoms can look like other issues (colds, sleep regressions, separation anxiety). Here is how to tell the difference:

Likely teething:

Excessive drooling (may cause a rash on chin or neck)
Chewing on hands, toys, crib rails — anything they can reach
Swollen, red, or bulging gums
Rubbing cheeks or pulling ears (referred pain from gums)
Fussiness that comes and goes (not constant)
Waking more at night but settling with comfort
Mild temperature (under 101°F / 38.3°C) — true fever is NOT a teething symptom

Probably not teething:

High fever (over 102°F) — this is an illness, call your doctor
Diarrhea or vomiting — not caused by teething
Green or foul-smelling mucus — likely an infection
Refusing all food or drink for more than one feeding
Rash on the body (not just the chin/neck from drool)

Why Teething Wrecks Sleep

Teething hurts more at night for the same reason any pain feels worse at night: there are fewer distractions, the body is still, and the brain focuses on the discomfort. Additionally, lying down increases blood flow to the head and gums, which can intensify the pressure sensation. For babies who cannot yet self-soothe, teething pain can mean waking every sleep cycle (every 45–60 minutes) and needing help to resettle.

How Music Helps a Teething Baby Sleep

While music cannot replace pain relief, it plays a powerful supporting role during teething disruptions:

Distraction during settling — the structured rhythm and melody give your baby's brain something to focus on besides the discomfort. A 2023 study showed that classical music significantly reduced pain response in newborns during medical procedures, and the same mechanism applies to teething pain.
Emotional comfort — familiar music triggers dopamine and serotonin release, which counteracts the stress response caused by pain.
Sleep bridging — when your baby wakes between sleep cycles because of gum discomfort, the same music they fell asleep to helps them recognize "it is still sleep time" and resettle more quickly.
Your voice on loop — the voice recording feature lets your baby hear you saying "it is okay, go back to sleep" on repeat, providing comfort without you having to go into the room every time.

The sleep timer with fade-out is especially useful during teething: set it for 30–60 minutes so the music plays through the initial settling and into deep sleep.

Safe Teething Relief

What helps

Cold teething rings — chill (do not freeze) a silicone teether. The cold numbs the gums. Never freeze teethers — frozen rubber can damage delicate gum tissue.
Clean, cold washcloth — wet a washcloth, wring it out, chill it in the fridge for 20 minutes, then let your baby chew on it.
Gentle gum massage — wash your hands and rub your baby's gums with a clean finger for 1–2 minutes before naps and bedtime.
Nursing or bottle — the sucking motion can be soothing. If nursing, be aware your baby may clamp down with new teeth — have a finger ready to break the latch.
Calming music + night light — the combination of familiar melody and gentle pulsating stars gives your baby a multi-sensory calming environment that reduces the perception of pain.

What to avoid

Teething gels with benzocaine — the FDA warns against benzocaine for children under 2 due to risk of methemoglobinemia (a dangerous blood condition).
Homeopathic teething tablets — the FDA has found inconsistent levels of belladonna in some products, making dosing unreliable.
Teething necklaces (amber or silicone) — these are a choking and strangulation hazard. The AAP strongly advises against them.
Frozen food in mesh feeders — can damage gums and pose a choking risk if pieces break off.
Alcohol or whiskey on gums — dangerous for babies, never do this.

Teething + Sleep Regression = Double Trouble

Teething often coincides with sleep regressions (4 months, 8–10 months, 12 months) because the timing of tooth eruption overlaps with major developmental milestones. When both hit at once, your baby may wake more frequently and be harder to settle. The solution: do not change everything. Keep your bedtime routine rock-solid — same music, same night light, same sequence. Familiarity is your most powerful tool when everything else (including your baby's mouth) feels uncomfortable.
