Tooth Growing Behind Baby Tooth

When a Tooth Grows Behind a Baby Tooth It can be surprising for parents to notice a new tooth growing in behind their child’s baby tooth. This is often called “shark teeth,” because two rows of teeth may be visible at once. While it may look concerning, it’s actually a common stage in dental development. This usually happens when the permanent tooth begins to erupt before the baby tooth has fallen out. Most often, it occurs in the lower front teeth around ages 6–7, but it can also happen with upper teeth. In many cases, the baby tooth will loosen and fall out on its own within a few weeks, allowing the permanent tooth to move into place. If the baby tooth remains firmly in place or your child experiences discomfort, it’s a good idea to visit the dentist. Sometimes, the baby tooth needs to be extracted to give the adult tooth enough room to shift forward properly. Encouraging your child to gently wiggle the loose tooth with their tongue or clean fingers may help speed things along. In the meantime, keep up with regular brushing and flossing to prevent plaque buildup around the crowded area. Although “shark teeth” may look unusual, they’re usually temporary and rarely cause long-term issues if managed early. A quick dental checkup can ensure the permanent tooth has the space it needs, helping your child’s smile grow in healthy and straight.
