Tongue piercing is a form of body modification where a small hole is made through the tongue to insert jewelry, typically a barbell. This procedure is usually performed by a professional piercer using sterile equipment to minimize the risk of infection. Healing time can vary, but it generally takes about 4 to 6 weeks for the tongue to heal completely. After the piercing, it is important to follow proper aftercare to avoid complications. This includes rinsing with an antibacterial mouthwash and avoiding certain foods that may irritate the piercing. Common jewelry materials include stainless steel, titanium, and bioplast, which are less likely to cause allergic reactions.
