Enamel is primarily formed before which of the following events?

Enamel is primarily formed before tooth eruption, which is the process where the tooth emerges through the gum tissue and enters into the oral cavity. Enamel, being the hardest substance in the body, is formed during the development of the tooth while it is still below the gums. This formation occurs during a specific time frame when the enamel matrix is laid down, then mineralized to reach its final hardness.

Once the tooth erupts, the enamel is already fully formed and will not undergo further development or growth. Understanding this process is crucial in dentistry as it helps in recognizing the importance of dental care during childhood and gestation when the teeth are forming, and also informs preventative measures against tooth decay and damage.

Tooth extraction, tooth decay, and tooth brushing happen after the tooth has erupted and while it is already present in the oral cavity, which indicates that enamel formation is completed prior to these events.
