A study says that stainless steel tongue studs might encourage more bacteria to grow than studs made of plastic.
this study, done at Innsbruck Medical University, involved 85 people who already had a tongue piercing. Each was given a new tongue stud. The stud was made from one of four materials: steel, titanium or two types of plastic. After 2 weeks, researchers looked at the bacteria around the piercings.
