Your child’s teeth begin to form before birth. The tooth eruption times and order can vary, however the first deciduous (or baby) teeth erupt around 6 months of age. Normally all 20 deciduous teeth have erupted by 3 years of age. The permanent teeth begin to erupt at approximately age 6 and can also vary in times and order. Adults normally have 32 teeth, which includes the third molars (or wisdom teeth). Please refer to the charts below for normal eruption times.
