Best Dental Retraction Liquids & Pastes AI pick
Chosen by an AI model from its trained knowledge, with its reasoning.
AI pick (line): 3M Astringent Retraction Paste
An aluminum chloride paste in single-use capsules that is syringed straight into the sulcus, giving retraction and hemostasis without packing cord.
Not for: Deep subgingival margins or thick, fibrous tissue, where a paste alone rarely retracts enough and cord is still needed.
AI picks by need
For paste with compression cap
Premier Traxodent (line)
An aluminum chloride retraction paste designed to be used with a compression cap or cotton roll for added displacement.
Not for: Clinicians who don't want an extra compression step.
For stiffer kaolin-based paste
Acteon Expasyl (line)
A firm kaolin and aluminum chloride paste injected with a dedicated dispenser for mechanical displacement as well as hemostasis.
Not for: Practices that don't want to buy a dedicated dispensing gun.
What the AI looks for in Dental Retraction Liquids & Pastes
- Margin depth
- Pastes suit equigingival or shallow subgingival margins. Use cord for deeper margins. A paste displaces tissue less than packed cord.
- Delivery system
- Check that the capsule or compule fits a dispenser you already own, or that one is included. Many pastes come in capsules that need a specific dispenser or gun.
- Rinse-off
- The paste must rinse out completely before impressing or scanning. Leftover astringent can interfere with how the impression material sets and with detail at the margin.
- Astringent type
- Aluminum chloride based pastes don't stain tissue. Ferric sulfate products can discolor tissue and dentin. Staining matters on anterior and esthetic cases.
Brands that matter
- 3M: Astringent Retraction Paste in single-use capsules.
- Premier: Traxodent paste. Also makes Hemodent liquid for soaking cord.
- Acteon: Expasyl kaolin-based paste with its own dispenser.
- Centrix: Retraction paste products delivered with its own syringe systems.
What to avoid
- Relying on a paste for deep subgingival crown margins.
- Leaving paste residue in the sulcus before impressing.
- Buying capsules without a compatible dispenser.
Questions
Do pastes replace cord?
For shallow margins they often can, and they are faster and gentler. For deep margins most clinicians still pack cord or combine cord with paste.
