Tongue Piercing Material Affects Bacterial Growth

Due to a recent study we got to know that stainless steel tongue studs may lead to more bacteria growth than studs made of plastic.

The study was held by the researchers from Innsbruck Medical University, involving 85 people who already had a tongue piercing. Each of those who were undergoing the experiment was given a new tongue stud, which was made from one of 4 different materials: steel, titanium and 2 various types of plastic. In 2 weeks time, the researchers looked at the bacteria around the piercings.
