Keller, Pediatric Tooth Eruption, TX
The first baby teeth that usually come into the mouth are the two bottom front teeth. On average you will notice this when your baby is about six to eight months old. Next to follow will be the four upper front teeth and the remainder of your baby's teeth will appear periodically. They will usually appear in pairs along the sides of the mouth until the child is about 2-1/2 years old.
At around 2-1/2 to 3 years of age, your child should have all 20 teeth. Between the ages of five and seven, the first permanent teeth will usually begin to erupt (average age is around six). Some of the permanent teeth replace baby teeth and some don't. Don't worry if some teeth are a few months early or late as all children are different.
Baby teeth are important as they not only hold space for permanent teeth, but they are important to chewing, biting, speech, and appearance. For this reason it is important to maintain a healthy diet and daily hygiene.
