Know these 6 things about primary teeth

• shorter, whiter and lighter

• enamel and dentin thinner about 1/2

• enamel rod direction cervical area occlusal instead of apical

• primary molars have significant buccal cervical bulge

Since the primary molars are being replaced with permanent pre-molars. the . . .

The primary tooth has nothing to do with the permanent tooth.
