If your baby was born early, count from their adjusted age rather than their birth date to figure out what's normal for them.\n\nGenetics are the main driver of timing, so there's genuine variation from baby to baby — and that's completely normal. A few other factors influence the timeline too: babies with higher birth weights tend to get teeth a bit later, while those who were smaller at birth may get them sooner. Growth overall matters more than feeding method, so don't worry if you're formula feeding or breastfeeding.\n\nThe most important thing is that your baby is growing well. If teeth come in earlier or later than you expected, that's usually nothing to stress about as long as development is on track overall.","sources":"[{\"title\":\"Timing of emergence of the first primary tooth in preterm and full-term infants.\",\"journal\":\"Annals of anatomy = Anatomischer Anzeiger : official organ of the Anatomische Gesellschaft\",\"year\":\"2016\",\"url\":\"https://pubmed.ncbi.nlm.nih.gov/26123712/\",\"score\":0.83},{\"title\":\"Timing of Primary Tooth Eruption in Infants Observed by Their Parents.\",\"journal\":\"Children (Basel, Switzerland)\",\"year\":\"2023\",\"url\":\"https://pubmed.ncbi.nlm.nih.gov/38002821/\",\"score\":0.83},{\"title\":\"Trends in Primary Tooth Emergence Pattern and Associated Factors in Japanese Infants.\",\"journal\":\"International dental journal\",\"year\":\"2023\",\"url\":\"https://pubmed.ncbi.nlm.nih.gov/36641344/\",\"score\":0.82},{\"title\":\"Relationship between pre-natal factors, the perinatal environment, motor development in the first year of life and the timing of first deciduous tooth emergence.\",\"journal\":\"Annals of human biology\",\"year\":\"2016\",\"url\":\"https://pubmed.ncbi.nlm.nih.gov/26065694/\",\"score\":0.78},{\"title\":\"Knowledge of Teething and Prevalence of Teething Myths in Mothers of Saudi Arabia.\",\"journal\":\"The Journal of clinical pediatric dentistry\",\"year\":\"2016\",\"url\":\"https://pubmed.ncbi.nlm.nih.gov/26696106/\",\"score\":0.75}]","view_count":0,"created_at":"2026-06-28T15:42:17.684Z"}
