Understanding Teething: What to Expect Teething is the natural process where a baby's first teeth erupt through the gums. While the timing varies, most babies begin teething around 6 months of age, with the two bottom front teeth typically appearing first, followed by the two top front teeth [1]. Common signs and symptoms of teething include [1]: Increased drooling Chewing on objects (toys, fingers, clothes) Irritability or crankiness Sore or tender gums A slight rise in temperature (not a fever) A facial rash due to excessive drooling It's important to note that while these symptoms are often attributed to teething, some common beliefs, such as teething causing fever or diarrhea, are generally not supported by medical evidence. If your baby experiences a high fever, severe diarrhea, or excessive crying, it's crucial to consult your pediatrician, as these symptoms may indicate an underlying illness unrelated to teething [1]. The Science of Teething and Sleep Disruption For generations, parents have anecdotally linked teething with significant sleep disturbances. However, recent research has begun to challenge this widely held belief. A longitudinal auto-videosomnography study by Kahn et al. (2025) investigated the relationship between teething and infant sleep using objective measurements [2]. "Both analytic approaches showed no significant differences in sleep metrics between teething and non-teething nights. Although over one-half of the parents reported sleep disturbances during teething, these subjective reports were not corroborated by the objective data. Conclusions: These findings challenge the widely held belief that teething disrupts sleep and highlight the need for pediatric health care professionals to consider alternative explanations for infant sleep problems." [2] This groundbreaking study, which monitored 849 infants aged 3-18 months, found no significant changes in objective sleep metrics - such as total sleep time, night-time awakenings, and parental crib visits - during teething periods compared to non-teething periods. While over half of the parents reported sleep disturbances, these subjective observation
