Can you use short barbells to pierce tongue?

It is possible to do so, but I advise against it. The mouth is a place that has a lot of germs in it, which is why many people suffer from tooth decay. If you pierce your tongue, germs may enter your bloodstream through that piercing, and this can cause serious illness. If you want body piercing, the tongue is pretty much the last place that you should choose. There are lots of other places to pierce yourself.

Listen closely, you don't want to try tongue piercing yourself, if you screw up and make a mistake you will do serious damage to yourself. Secondly you do not have the knowledge or the equipment to sterilize the materials and jewellery correctly.

Methicillin-resistant Staphylococcus aureus (MRSA) is a bacteria responsible for several difficult-to-treat infections in humans. This is antibiotic resistant and can be life threatening if contracted. As of just recently there have been quite a few cases of this occurring due to self piercing and poor judgement.

Short barbells if they are too short can result in the tongue piercing swelling to the point where the barbell is drawn into the tongue piercing and emergency surgery has been required to remove the barbell from the tongue.
