Teething usually starts between four to seven months. The two front teeth (central incisors), either upper or lower, usually appear first, followed by the opposite front teeth. The first molars come in next, followed by the canines or eyeteeth.
By age two and a half, your child should have all his primary (or baby) teeth, including the second molars. It is important to care for your child's teeth to prevent decay, as well as other problems.
