| Base Type | Common Gauges | Typical Post Lengths | Fitting System |

| Belly bar base | 1.6mm (14g) | 8mm, 10mm, 12mm | Screw, internally threaded |
| Screw base | 1.2mm (16g), 1.6mm (14g) | Varies by product | Screw |

Exact specifications vary by individual product listing. Check product pages for confirmed gauge, length, and material details before purchasing.
- Suitable for professional piercers and studios sourcing jewellery bases for client use — no separate trade account required
- Implant-grade titanium bases (ASTM F136) are recommended by the Association of Professional Piercers (APP) for initial and healing piercings where applicable
- Internally threaded and push-fit systems are preferred for fresh piercing placements — no exposed threads pass through tissue on insertion
- Bioflex bases may be appropriate for oral piercings or high-movement placements where post rigidity causes client discomfort
- Downsizing post-healing: standard practice is to move from longer initial post (8–10mm) to shorter wearable length (6–7mm) once swelling resolves — base selection should reflect confirmed healed anatomy
- Material suitability for sensitive or reactive clients: confirm nickel content per product listing before recommending 316L surgical steel options
- Implant-grade titanium bases reference ASTM F136 grade where specified — confirm per individual product listing
- 316L surgical steel contains a small percentage of nickel as part of its alloy composition — not recommended for confirmed nickel-sensitive wearers
- Bioflex is a flexible polymer material — not an implant-grade metal; suitable for specific placement needs, not a general upgrade from steel or titanium
- Gold labret backs should be solid 14k or 18k gold — gold-plated options are not suitable for use inside a piercing channel; confirm per product listing
- Do not attempt to fit a labret back of incorrect gauge into an existing piercing — forced insertion of an incorrect size can cause tissue damage
- Not all threading systems are cross-compatible — confirm fitting type (threaded, push-fit, screw) matches your existing tops before purchasing
- This product is intended for use on healed or professionally assessed piercings. Consult a qualified professional piercer or licensed medical provider for guidance on healing piercings or known skin sensitivities.

Jewellery bases and labret backs sold on this page are intended for use on healed or professionally assessed piercings only. Material suitability, gauge, and post length must be confirmed before use — incorrect sizing or incompatible materials can cause discomfort, irritation, or tissue damage. Aftercare and healing times vary by individual. This product information does not constitute medical advice. Consult a qualified professional piercer or licensed medical provider before changing jewellery in an unhealed or reactive piercing. Monster Piercing is not responsible for outcomes resulting from incorrect self-fitting or use of products in unhealed piercings without professional guidance.

What is a labret back?
A labret back is the post and flat disc component of a labret stud — the part that sits inside the piercing channel and holds the decorative top in place. The flat disc sits flush against the inner surface of the skin or inside the mouth, while the post extends through the piercing. The decorative top attaches to the external end of the post via a threading system or push-fit connection.
-
What is the difference between a threaded and push-fit labret back?
An internally threaded labret back has threads cut into the inside of the post end. The decorative top has a small external pin with threads that screws into it. A push-fit (threadless) labret back has a hollow open end — the top's bent tension pin inserts into this opening and is held by spring pressure. The two systems are not interchangeable. Confirm your existing tops' fitting type before purchasing a replacement base.
-
What size labret back do I need?
Two measurements matter: gauge and post length. Standard gauge for most labret placements in UK practice is 1.2mm (16g). Some placements use 1.6mm (14g). Post length typically ranges from 6mm to 10mm — initial piercing jewellery is longer to accommodate swelling; downsized jewellery for healed piercings is usually 6mm or 7mm. If replacing an existing labret back, measure the current post directly or confirm the length with your piercer.
-
Is implant-grade titanium better than surgical steel for labret backs?
For healing piercings or wearers with metal sensitivities, implant-grade titanium (ASTM F136) is the preferred material. It contains no nickel in its alloy composition and is genuinely biocompatible. 316L surgical steel is appropriate for most healed piercings but does contain a small percentage of nickel, which can cause reactions in nickel-sensitive individuals. For long-term everyday wear in a healed piercing, both materials are used widely — the choice depends on individual sensitivity and budget.
-
Can I use a labret back as a replacement for a lost back on my existing jewellery?
Yes, provided the replacement back matches the gauge and threading system of your existing jewellery. Internally threaded backs only pair with internally threaded tops; push-fit backs only pair with push-fit tops. Gauge must also match — a 1.2mm post will not pair with a 1.6mm top. Check the specifications of your existing jewellery before purchasing a replacement labret back.
-
Are labret backs suitable for oral piercings?
Flat back labret posts are commonly used for lip, Monroe, Medusa, and cheek piercings where one end sits inside the mouth. For oral placements specifically, the material and length of the post matter — longer posts are used initially to account for swelling, and the internal disc must be smooth and flat to avoid tooth and gum contact. Bioflex labret backs are sometimes used in oral piercings to reduce pressure on dental enamel. Consult your piercer for material and sizing recommendations for oral placements.
-
Do you offer labret backs for professional piercers and studios?
Yes. Monster Piercing's catalogue is available to individual buyers and professional piercers sourcing jewellery for studio use — no separate trade account is required. Check individual product listings for available quantities and pricing.
