If your child has a permanent tooth behind a baby tooth, you may be seeing a common eruption pattern often called “shark teeth.” Get clear, parent-friendly guidance on what to watch for, when a baby tooth may still fall out on its own, and when dental care may help.
Tell us whether the adult tooth is clearly behind the baby tooth, whether the baby tooth is loose, and what you’re noticing so you can get personalized guidance for this exact situation.
When an adult tooth is erupting behind a baby tooth, it often means the permanent tooth is following its own path while the baby tooth has not fallen out yet. This can happen with lower front teeth and other areas of the mouth. In many cases, the baby tooth loosens and comes out as the adult tooth continues to move forward. The key questions are how loose the baby tooth is, how far the permanent tooth has come in, and whether your child has pain, swelling, or trouble biting.
