Laura first noticed that her lower
left* right central incisor was loose over Labor Day weekend. A month and a half later, the baby tooth has gotten much looser, but still holds tight. Behind the baby tooth, the permanent tooth has pushed out of the gum. Laura is proud to have 21 teeth, if only for a short time. She tells me that the baby tooth is a princess and the permanent tooth is a prince. The prince uses his sword to fight off the hard foods that cause the princess pain.
The permanent tooth coming behind the baby tooth has me concerned. This semi-reassuring article calls them “lingually erupting mandibular incisors” and “shark teeth.” About 10% of kids have this condition, which is thought to be caused by tooth crowding, extremely stubborn baby teeth roots, permanent teeth developing further back in the gum than normal, or some combination of the three. Most of the time, the condition corrects itself when the baby tooth falls out. Laura has a dentist appointment in early December. I will place my worry on hold for now. Laura teethed early and fiercely (kicked out from a daycare at 18 months for biting), so her shark tooth fits her dental drama M.O.
* Looking at picture, I realized that I used my left, not Laura’s left to determine tooth placement.
