Although the mandibular first molars are the first permanent teeth to erupt,they are NOT succedaneous because they do NOT replace primary teeth.It is important to remember that primary molars are replaced by permanent premolars.Therefore,the first succedaneous teeth to erupt are the permanent mandibular central incisors,which replace the primary mandibular central incisors.The cusp of Carabelli is a cusp like elevation located on the maxillary first molar and occasionally on the maxillary second molar.
