“Our study found that many people with oral piercings had deep pockets and gaps around their teeth, and receding and bleeding gums,” said study author Dr. Clemens Walter, a professor at University Medicine Greifswald in Germany. “These are all signs of periodontitis, also called gum disease, which can lead to tooth loss.”
Walter and his colleagues analyzed eight studies that included 408 people with a combined 236 lip piercings and 236 tongue piercings. In all, 1 in 5 had more than one oral piercing. The participants reported having their piercings ranging from one month to 19 years, and most folks wore metal jewelry in their piercings.
The studies compared teeth and gums next to the piercings with areas elsewhere in the mouth.
In addition, 3 of 4 studies looking at lip piercings revealed receding gums in the area.
The study review was presented Wednesday at a meeting of the European Federation of Periodontology, in Copenhagen. Research presented at meetings is typically considered preliminary until published in a peer-reviewed journal.
“The findings suggest that oral piercings, especially in the tongue, negatively affect the adjacent teeth and gums,” Walter said in a meeting news release. “In those with tongue piercings, damage was particularly notable around the bottom two front teeth, called the mandibular incisors, which are important for biting and chewing food.”
The likelihood of tooth and gum damage appeared to increase with time, he added.
His advice: “People with tongue and lip piercings should remove them to protect their teeth and gums from further damage,” Walter said.
Previous research has yielded similar findings. Researchers on the new study urged dentists to tell their patients about the risk of complications from wearing oral piercings.
