Time for teething.
Generally, the primary teeth (first to show up) arrive between 6 and 8 months of age. But, if your child is a few months early or delayed until they are over 1 you shouldn't be concerned. Some children get one
at a time, while others seem to get all of their teeth at once. Most children express some sort of discomfort during this process and we recommend palliative treatment such as cool teething toys and tylenol) as recommended by your pediatrician).
Your child should have all twenty baby teeth by the time they are 3 years old. Most permanent teeth begin showing up at age 6 around the time that the first baby teeth begin to fall out.
