Question

What is the full form of COO​

Answer 1

Answer:

Hii,

Explanation:

Having more than six permanent teeth missing is known as oligodontia, and a total absence of adult teeth is referred to as anodontia. Researchers estimate that as many as 20 percent of adults are born with at least one missing tooth, making hypodontia one of the most common developmental oral health conditions.

Answer 2
