Most of the baby milk teeth eruption time is about 6 to 10 months, but due to individual differences, so the time of the eruption of milk teeth there are differences, some babies in about 5 months, may have already erupted milk teeth, but some babies around 11 months, only began to appear the eruption of milk teeth. If your baby’s physical development is within the normal range, it is normal to have no teeth at 11 months, so pay more attention to observation. If your baby still has no eruption of milk teeth after 13 months, we suggest that you consult a doctor in time for treatment. Usually, most of the time, the non-eruption of milk teeth is due to a lack of calcium, which is accompanied by symptoms such as X-shape legs, chicken chest, and difficulty in falling asleep. If your baby is over 11 months old and still has no erupted teeth, it is recommended to go to the hospital in time to complete the relevant examinations to avoid accidents.
