thumb | right | Dental concrescence between a 2M (erupted) and a higher 3M (retained) Concrescence is an uncommon developmental condition of teeth where the cementum overlying the roots of at least two teeth fuse together without the involvement of dentin. Usually, two teeth are involved with the upper second and third molars being most commonly fused together. The prevalence ranges 0.04–0.8% in permanent teeth, with the incidence being highest in the posterior maxilla.

== Signs and symptoms == Problems with tooth positioning causing cheek biting and traumatic ulcers. Involved teeth may have difficulty erupting or may not erupt completely. Possible gum disease (localized periodontal destruction due to aetiological factors, e.g. funnel development leading to plaque accumulation) Cavities (caries) due to predisposition from crowded teeth and misalignment. May cause fracture of the tuberosity or floor of the maxillary sinus.
