What is the peak eruption speed of a tooth when its cusps emerge through the surface epithelium, measured in micrometers per day?

Explanation

The highest eruption rate of a tooth, occurring as the cusps break through the surface epithelium, is approximately 75 micrometers per day. Rates such as 100, 50, or 25 micrometers per day are either too high or too low compared to this peak value.
