Another very common question we are asked by parents! Children start to get their permanent teeth on average around age 6. While those new front incisors are coming in the front of the mouth, the rest of the mouth is filled with milky-white baby teeth. It is generally the contrast of normal appearing permanent incisors (which are typically more yellow than the baby teeth) up against the very white baby teeth that makes the new permanent teeth appear slightly more yellow. The contrast becomes less and less as the baby teeth continue to fall out. Eventually, a natural-appearing, beautiful smile will take place and you will wonder how your child grew up so fast!
