First, your child gets her tongue pierced. Then, as if you needed something
else, she starts "playing" with the tiny barbell-shaped stud, pushing it against
her upper front teeth. And before you know it, she forces a gap between those
teeth -- a fraction-of-an-inch gap that may cost thousands of dollars in
orthodontic bills to straighten.
How and why this happens has been documented in a case study by University at
Buffalo researchers published in the July issue of the Journal of Clinical
Orthodontics.
"It is a basic tenet of orthodontic that force, over time, moves teeth,"
explains the study's primary investigator, Sawsan Tabbaa, DDS, MS, assistant
professor of orthodontics at the UB School of Dental Medicine.
Tabbaa notes that a previous UB dental school survey study of Buffalo high
school students revealed that the presence of a barbell implant/stud caused a
damaging habit whereby subjects pushed the metal stud up against and between
their upper front teeth, a habit commonly referred to among the students as
"playing."
"And it happened in very high percent of the cases," said Tabbaa.
That repeated "playing" with the stud may result in a gap as is demonstrated
in Tabbaa's current case study.
The study involved a 26- year-old female patient examined at UB's orthodontic
clinic who complained that a large space had developed between her upper central
incisors or upper front teeth. The patient also had a tongue piercing that held
a barbell-shaped tongue stud.
The tongue was pierced seven years earlier and every day for seven years she
had pushed the stud between her upper front teeth, creating the space between
them and, subsequently, habitually placing it in the space. The patient did not
have a space between her upper front teeth prior to the tongue piercing.
"The barbell is never removed because the tongue is so vascular that leaving
the stud out can result in healing of the opening in the tongue, said Tabbaa,
"so it makes perfect sense that constant pushing of the stud against the teeth
-- every day with no break -- will move them or drive them apart."
The patient provided the research team with photos that demonstrated she had
no diastema, or space, prior to having her tongue pierced. For the purposes of
treating this patient's space, it was assumed that positioning of the tongue
stud between the maxillary central incisors or "playing" caused the midline
space.
Her treatment involved a fixed braces appliance to push the front teeth back
together.
Tongue piercing can result in serious injury not just to teeth but has also
been associated with hemorrhage, infection, chipped and fractured teeth, trauma
to the gums and, in the worst cases, brain abscess, said Tabbaa.
"The best way to protect your health, your teeth and your money is to avoid
tongue piercing."
