The international notation has a different numbering system than the previous two, and the right permanent mandibular first molar is known as "46", and the left one is known as "36". Mandibular permanent first molars usually have four pulp horns. The first molar is usually the first permanent tooth to erupt at 6–7 years and has adult undertones.
There are 20 primary teeth and they typically erupt in the following order: (1) central incisor, (2) lateral incisor, (3) first molar, (4) canine, and (5) second molar. [13] As a general rule, four teeth erupt for every six months of life, mandibular teeth erupt before maxillary teeth, and teeth erupt sooner in females than males. [14]
The mandibular first molar is the tooth located distally from both the mandibular second premolars of the mouth but mesially from both mandibular second molars. It is located on the mandibular arch of the mouth, and generally opposes the maxillary first molars and the maxillary 2nd premolar. This arrangement is known as Class I occlusion.

However, this procedure is invasive and usually requires local anesthetic and tooth preparation (drilling).
Procedures for root canal. The space inside the root canals is filled with a highly vascularized, loose connective tissue, called dental pulp.
