The procedure in which teeth that are in the process of developing rise from the jawbone, pierce the gum tissue, and become visible within the mouth.
Typically, deciduous teeth, also known as milk teeth, start to emerge around the age of six months. By the time a child reaches three years old, all 20 of these milk teeth have usually made their appearance.
Permanent teeth, also referred to as secondary teeth, typically start to emerge around the age of six. The initial permanent molars surface towards the rear of the mouth, alongside the existing deciduous teeth. The appearance of permanent teeth closer to the front of the mouth is usually preceded by the dissolution of the roots of the deciduous teeth, which leads these teeth to loosen and eventually fall out. In time, permanent teeth take the place of all the deciduous teeth.
Wisdom teeth, also known as the third molars, typically emerge between the ages of 17 and 21. However, in some individuals, these teeth never surface. In other cases, wisdom teeth can become impacted, meaning they are obstructed from fully erupting due to a lack of adequate space in the jawbone.
