Bioplast & Acrylic Tongue Rings

The tooth-friendly end of the tongue wall. Two kinds, both plastic where it counts: acrylic-ball barbells that put a soft end between the bar and your teeth, in glow-in-the-dark, marble, glitter and clear, and fully flexible bioplast bars with no metal at all for X-rays, sports and mouths that argue with steel. All 14G, nearly all 5/8 inch, priced to swap on a whim. Since 1999.

Plastic Tongue Ring Fit & Material Guide

Which plastic is which: an acrylic-ball barbell is a 316L steel bar with hard plastic ends; the metal passes through the piercing, the soft ball meets your teeth. A bioplast or bioflex bar is a flexible medical-grade polymer with no metal anywhere, the piece you want for dental X-rays, an MRI, contact sports or a workplace that bans metal. UV acrylic lights up under blacklight; glow-in-the-dark charges in daylight. The product title tells you which you are getting.

Teeth, honestly: an acrylic end softens the blow when a bar meets a tooth, which is why piercers suggest it for veneers, caps and chronic clickers. It makes the habit cheaper, not safe. A properly downsized bar and a tongue that leaves the jewelry alone still do most of the protecting.

Fit: 14G, with 5/8 inch (16mm) the everyday length and 5mm to 6mm balls. Care: warm water and mild soap only; acrylic scratches and clouds over months, so replace a tired ball rather than nurse it, and never boil or autoclave it. Bioplast is inert and sits on the piercing standard's list of materials suited to fresh and sensitive piercings; let your piercer make the call on a new piercing's first change.

FAQ

Both kinds live here, and the title tells you which. Acrylic-ball barbells are a 316L steel bar with plastic ends: metal through the piercing, soft ball against your teeth. Bioplast and Bioflex bars are plastic all the way through, flexible, with no metal anywhere. If you searched for a plastic tongue ring because you need no metal in your mouth, look for Bioplast, Bioflex or Flexible in the name.

For the ball, yes. An acrylic or soft-plastic end softens the impact when the bar meets a tooth, which is why piercers suggest it for anyone with veneers, caps or a clicking habit. It does not make clicking safe; it makes it less expensive. A correctly downsized bar and a tongue that leaves the jewelry alone still do most of the work.

Any time metal is the problem: dental X-rays and MRIs, contact sports, a workplace that bans metal, or a mouth that reacts to steel. Bioplast is an inert medical-grade polymer that bends with your tongue, and the piercing standard lists it among the materials suited to fresh and sensitive piercings. For a new piercing, still let your piercer make the call on the first change.

Bioplast and Bioflex are brand names for the same idea: a flexible, body-safe polymer bar. Acrylic is the hard clear plastic used for balls, glitter, marble and glow designs. UV acrylic is acrylic that lights up under blacklight; glow-in-the-dark charges in daylight and glows on its own. None of them are metal; only the bioplast and bioflex bars are soft.

Months of daily wear, not years. Acrylic scratches, clouds and can eventually crack, and a rough ball is hard on the piercing, so replace it the moment it looks tired. At these prices that is the whole plan: treat acrylic as the fun, swappable layer and keep a spare in the drawer. Never put acrylic in boiling water or an autoclave; warm water and mild soap only.

The same as any tongue ring: 14G, with 5/8 inch (16mm) the everyday length once the swelling is gone, and balls of 5mm to 6mm. A flexible bar forgives a little extra length better than steel does, but it still should not flop. Match the bar you wear now; every product page lists gauge, length and ball size.
