Question
Is it due to a lack of certain nutrients or other reasons that a 15-month-old baby has only 4 teeth? Are there any treatments available?
Answer
The timing of tooth eruption is related to the baby’s physique and nutrition, and there are individual differences. The time for baby teeth to erupt usually ranges from 4 to 10 months. Most babies start teething between 6 and 7 months, but there is no need to worry if the first tooth appears only at 1 year old, as this usually does not cause health problems. By the age of 2, a child should have 20 primary teeth.
