Early Extraction and Immediate Spacer
When Edward was 6 year old, his bottom 1st baby molar (Fig.1 D) has severe root tip infection (*), which may affect the underlying developing adult tooth (4). The infected baby tooth was taken out and a spacer was immediately placed and fixed in the 2nd baby molar (E). The spacer keeps the space and helps the underlying permanent tooth coming out (Fig.2 (3 years later) arrow). Now Edward is 13 years old; his bottom teeth look normal (Fig.3,4).
