Flatbacks
Pros:
✓ Fewer crevices = fewer bacterial traps — especially with push-fit or internally threaded styles
✓ Flat base doesn’t dig into skin, lowering the risk of irritation
✓ Less friction during healing, meaning lower chance of fluid buildup or “crusties”
✓ Easier to clean with saline solution
Cons:
✗ Threadless styles can pop out if not pushed in properly — which may expose the healing piercing
✗ Flatback discs can trap moisture if not dried after cleaning (especially in humid environments)
Barbells
Pros:
✓ Threaded balls are secure and easy to remove for cleaning
✓ Widely available, easy to sterilize
✓ Comes in medical-grade materials like titanium or implant-grade surgical steel
Cons:
✗ More gaps and threads = higher chance of buildup
✗ Ball ends can trap bacteria or get gunky over time
✗ More prone to movement, which slows healing and increases exposure to germs
