What is the best guide for an erupting permanent tooth?
A
No guide is needed
B
Primary tooth
C
Space maintainer
D
None of the above
Explanation: 

Detailed explanation-1: -For one thing, primary teeth serve as guides for the eruption of permanent (adult) teeth, holding the space into which these new teeth will erupt. The crowns (tops) of the permanent teeth actually push against the roots of the baby teeth, causing them to resorb, or melt away.

Detailed explanation-2: -Primary teeth are the valuable assets of a child. In children, milk teeth/primary teeth play a vital role for eating, phonetics, esthetics and also as a space maintainer for permanent teeth.

Detailed explanation-3: -Between 6 to 7 years of age, the permanent mandibular incisors erupt, followed by the permanent maxillary incisors between 7 to 9 years of age.

Detailed explanation-4: -Lower teeth usually erupt before upper teeth. Teeth in both jaws usually erupt in pairs–one on the right and one on the left. Primary teeth are smaller in size and whiter in color than the permanent teeth that will follow. By the time a child is 2 to 3 years of age, all primary teeth should have erupted.
