In general, infants erupt their mandibular milk incisors around six months of age and all milk teeth erupt around two and a half years of age. The order of eruption is incisor, first molar, cuspid, and second molar.
Infants usually erupt mandibular milk incisors around six months, maxillary milk incisors around seven months, mandibular milk lateral incisors around eight months, maxillary milk lateral incisors around nine months, first molar around one year, cuspids around one and a half years old, second molar around two and a half weeks old, and all the 20 milk molar teeth have erupted.
The process of tooth eruption is subject to individual differences, and there are variations in the order and timing of tooth eruption, with some starting to erupt their milk incisors at 3 to 4 months, and others at 8 to 9 months, which is generally normal.
If there is any abnormality during the process of tooth eruption, it is recommended to consult a doctor in time for examination and treatment under the doctor’s guidance to avoid delaying the condition.
