Many parents notice that teething seems worse at night. The baby who managed reasonably well during the day becomes inconsolable after bedtime, waking repeatedly, unable to be settled by the usual means. This is not imagination: teething pain does tend to intensify at night, for physiological reasons that are worth understanding.
Healthbooq covers infant health and sleep across the first years.
Why Teething Pain Is Worse at Night
During the day, a baby's attention can be redirected. Novelty, interaction, motion, feeding – all of these engage the nervous system and reduce the brain's focus on gum discomfort. Pain perception is partly a function of attention: when there are more interesting things to process, painful stimuli are less prominent. At night, with reduced stimulation and nothing to distract, the same level of gum inflammation is perceived more intensely.
There is also a postural component. When a baby lies flat, blood pressure in the head and gums may increase marginally, which can intensify the throbbing quality of inflammation-related pain. This is the same mechanism that makes toothache in adults typically worse when lying down.
Cortisol – the body's natural anti-inflammatory hormone – follows a circadian rhythm, peaking in the morning and declining through the day and overnight. The lower cortisol levels of the nighttime hours provide slightly less buffering against inflammatory pain.
Distinguishing Teething Waking from Other Night Waking
Teething-related night waking tends to cluster around the period when a tooth is visibly close to or just breaking through the gum. The gum will appear swollen, red, and possibly have a small bruised-looking area where the tooth is about to emerge. If a baby is waking frequently every night without visible gum changes and without recent teething, other causes (developmental sleep regressions, illness, hunger, sleep association changes) are more likely explanations.
Genuine teething night waking typically improves when pain relief is given and worsens when it is withheld. If comfort measures and appropriate analgesia make no difference to waking pattern, it may not be teething.
Management at Night
Paracetamol or ibuprofen given before bedtime is the most effective intervention when a baby has been clearly teething during the day. A dose of age-appropriate liquid paracetamol or ibuprofen (ibuprofen from 3 months and 5kg) given 30-60 minutes before the expected sleep period allows the medication to become effective as the baby settles. This approach is appropriate on nights when daytime teething discomfort has been clear; it should not be used routinely without evidence of teething.
Chilled teething ring given at the feed before bed provides gum counter-pressure and mild cold before sleep. A teething ring cooled in the refrigerator (not the freezer) can be offered at the bedtime feed.
Gum massage with a clean adult finger can be helpful in the settling process.
Teething gels at night are not recommended for young infants. The concern is not a single application but repeated applications through the night: parents giving gel at each waking may inadvertently deliver excessive doses of local anaesthetic over several hours. The MHRA advises against lidocaine-containing gels in under-2s specifically, and benzocaine-containing gels carry a risk of methaemoglobinaemia. Gels containing choline salicylate are not recommended in children under 16.
When Teething Night Waking Becomes a Habit
If a baby requires frequent night contact to resettle during a teething period and this is responded to consistently, the night waking may persist after the tooth has erupted via habit. This is common and does not represent a problem with the child. Most families find that sleep patterns improve within a week or two of the tooth emerging, particularly if some element of independent settling was present before the teething episode.
Key Takeaways
Teething discomfort is genuinely worse at night for two reasons: distractions that occupy a baby during the day are absent, and lying down can increase blood pressure in the gums, intensifying the throbbing sensation. Night waking during teething is common and predictable. The most effective interventions are paracetamol or ibuprofen given at an appropriate dose shortly before bedtime when a baby has been clearly uncomfortable during the day. Teething gels are not recommended for overnight use in young infants due to the risk of repeated application and absorption of local anaesthetic agents.
