Baby actually grew his or her baby teeth before birth. At about four months of age, they begin to move to the surface. During teething, the baby may drool more, and show a desire to bite and chew on things. The baby may also show signs of mild pain. By the age of 3, all 20 teeth should be out.
Many remedies are available.
Some popular folk remedies really do work, Domoto says. UW dentists recommend rubbing and cleaning the area where the teeth are erupting. Give the baby something clean and safe to bite on. You might chill the teething ring, or even rub a clean finger on the sore gum. Teething might be nature's way of reminding you that your baby's teeth are the foundation of a healthy mouth.
