An average tooth pierces gingiva with how much root formation?
1/2
2/3
3/4
Complete
The correct answer is: 3/4
An average tooth pierces the gingiva with about 3/4 or 75% of its root formation. This is because the root of a tooth grows and matures at different rates, with the front teeth typically having shorter roots than the back teeth. Options A, B, and D are incorrect because 1/2, 2/3, and a complete root formation do not accurately reflect the average amount of root formation for a tooth piercing the gingiva. It is important to note that this measurement may vary slightly depending on the individual's tooth development and anatomy.
