Our babies' teeth begin to break through the gums at about 6 months of age. Usually, the first two teeth to erupt are the bottom front teeth. Next, the top four front teeth emerge. After that, other teeth slowly begin to fill in, usually in pairs -- one each side of the upper or lower jaw -- until all 20 teeth have come in by the time the child is 2 ½ to 3 years old. The complete set of primary teeth is in the mouth from the age of 2 ½ to 3 years of age to 6 to 7 years of age. The best time to bring your child to the dentist is around 3 years of age. Begin teaching them to brush when the first teeth erupt. Even if the baby only plays with the toothbrush in their mouth, it gets them used to a routine of brushing two to three times a day. And remember…do not use toothpaste until the child is older because you don’t want them to "eat" the toothpaste.
