Baby teeth, technically “primary teeth” start coming in about 6 months old and keep coming in until age 2 or 3. Eventually, those baby teeth are all replaced by permanent teeth – starting around age five and continuing through adulthood when wisdom teeth come in. We are born with a set of 20 primary teeth, which are eventually replaced with 32 adult teeth.
Those baby teeth have a big job – not only do they help our kiddos chew their food, they also hold space in the jaw for the larger permanent teeth to come in. With primary teeth, we have 10 teeth on top and 10 on the bottom. When our adult or permanent teeth come in, they are larger and slightly darker, and we end up with 16 teeth on the top and 16 on the bottom.
