Gracey curettes are area-specific by design — each numbered pair is angled for a particular tooth surface, which is exactly what makes them more effective than a universal curette for fine subgingival work, provided you're reaching for the right number.
Reading the numbering system
- Gracey 1/2 & 3/4 — anterior teeth, facial and lingual surfaces
- Gracey 5/6 — anterior teeth and premolars
- Gracey 7/8 & 9/10 — posterior teeth, facial and lingual surfaces
- Gracey 11/12 — posterior teeth, mesial surfaces
- Gracey 13/14 — posterior teeth, distal surfaces
Why the offset blade matters
Unlike a universal curette, a Gracey blade is angled roughly 70 degrees to the lower shank, so only one cutting edge engages the tooth when the instrument is correctly adapted — this is what allows subgingival access without unnecessary tissue trauma.
What to look for in a set
- Precision-ground edges that hold a fine cutting angle through repeated sharpening
- Balanced handle weight for extended scaling sessions
- Surgical-grade stainless steel that resists corrosion from sterilisation and stays sharp longer between resharpenings
A properly numbered Gracey set, matched to the surfaces you treat most, makes subgingival instrumentation faster and more comfortable for both hygienist and patient. Browse our full Periodontal range for Gracey, universal and surgical curettes built for UK practices.
