Hello, it is a primary first molar tooth. The normal age for shedding primary first molar tooth is 9-11years. Children typically begin shedding their primary teeth at the age of 6 years, starting with the central incisors and followed about a year later by the lateral incisors. The first molars are shed next, closely followed by the lower canines. The upper canines and both upper and lower second molars are shed last.
