The insertion of metal objects into intraoral and perioral sites is growing in popularity. However, there are numerous oral and dental complications associated with tongue piercing. Fifteen patients with tongue piercings (pierced in the body of the tongue, anterior to the lingual frenum) attending the dental office of the authors, with and without complaints, were clinically and radiographically examined. The most common dental problem registered was chipping of teeth. Furthermore, two cracked teeth and four teeth with cusp fractures were also seen. One case of selective dental abrasion was registered. Trauma to the lingual anterior gingiva was the most common gingival problem. A salivary flow stimulating effect was only reported by 2 of the 15 individuals. None of the patients complained of interference with speech, mastication and swallowing. One case of galvanic currents produced by the appliance was registered. On the basis of the registered data, we concluded that patients need to be better informed of the potential complications associated with tongue and oral piercings, and that the dental profession can serve this role.

Piercing of the tongue and perioral regions is an increasingly popular expression of body art, with more patients coming in for a routine check-up with tongue and/or lip piercings. Several complications of oral piercing have been reported, some of which are life-threatening. In the present clinical survey the prevalence of both tongue and lip piercing complications in oral health was assessed in a group of 50 patients. The most common dental problem registered was chipping of the teeth, especially in association with tongue piercing. Gingival recession was seen as a result of lip piercing with studs. Postprocedural complications included oedema, haemorrhage and infection. Therefore, dentists and oral and maxillofacial surgeons should be given more authority to advise patients with oral and facial piercings or those who plan to acquire this type of body art

Extensive extrusion of calcium hydroxide into the periapical tissues does not appear to comprise periapical healing. Despite this finding, the deliberate extrusion of dental materials into the apical tissues is not advocated.
