Food embedment brings great pain and inconvenience to patients, researchers have devoted to its prevention and treatment research for many years, but no special method has been achieved yet. Clinically, there are some simple and effective methods, mainly include: 1.For patients with dental caries and bad filling causing embedment, silver amalgam or light-curing resin can be used for restoration. 2.For the two teeth contact relationship is normal but the jaw surface is uneven or mildly misaligned, the jaw can be adjusted to restore and adjust the marginal ridge, reconstruct the food overflow groove and restore the normal adjacent contact relationship. 3.Posterior teeth with poor contact, underbite, unsatisfactory jaw adjustment and poor filling of large caries should be restored by metal full crown, metal porcelain full crown, joint crown or wearing ring. The movable denture restoration should pay attention to increase the anti-embedding parts. 4.For adolescents with uneven teeth, misaligned individual teeth or poor jaw relationship, orthodontic treatment should be preferred if conditions allow. 5.If the third molar has caries, misalignment, loosening, elongation and no opposing teeth, the embedded third molar can be extracted.
