Shark teeth can happen at any time, but they are most common during two periods in a child's development. The first time is around age 6, when the lower front teeth usually grow in. The second is around age 11, when the upper back molars appear.
In rare cases, a couple of new teeth come in before the old ones are gone, creating two rows of pearly whites. This is a temporary stage, sometimes called shark's teeth. If your 6- or 7-year-old complains of soreness in the back of his mouth, it's probably the first permanent molars coming in. (He has no baby teeth there to fall out first).
