What Is a Curette? A Complete Guide to Its Uses and Types in Dentistry

A dental curette is a hand instrument used primarily for subgingival scaling, calculus removal, and root surface debridement. It features a rounded toe and back with a sharp cutting edge, which allows clinicians to work effectively below the gumline without traumatizing soft tissues.

It is an essential instrument in every dentist’s arsenal because it enables very precise periodontal therapy, removing plaque and calculus while preserving gingival health. Curettes are foundational to both preventive care and active periodontal treatment.

This blog will give you a complete guide to dental curettes, including their types, design features, usage, and handling tips.

A Brief History of Dental Curettes

The origins of dental curettes trace back to early periodontal instruments developed in the late 19th and early 20th centuries, as dentistry began shifting toward preventive and periodontal care.

Dr. Clayton H. Gracey, a dentist and educator at the University of Michigan, played a pivotal role in modern curette design by introducing area-specific curettes that improved access and efficiency in periodontal pockets. These innovations from the 1940s are what we today call Gracey curettes.

Over time, curettes evolved from simple hand-forged tools to highly engineered instruments with advanced metallurgy, ergonomic handles, and precision blade angulations.

Today, the global dental hand instruments market, including curettes, continues to grow steadily, driven by increased awareness of periodontal health, rising dental visits, and continuous innovation in instrument design and materials.

Difference Between a Curette and a Scaler

Although curettes and scalers may appear similar, they serve different clinical purposes. Scalers typically have pointed tips and triangular cross-sections, making them ideal for removing supragingival calculus above the gumline.

Curettes, by contrast, feature a rounded toe and back, which allows safe and effective subgingival instrumentation. Their design minimizes tissue trauma, making them the preferred choice for root planing and periodontal maintenance.

Types of Curettes

Universal curettes and Gracey curettes are the two most common types used in clinical practice. Universal curettes are designed for use throughout the mouth, while Gracey curettes are area-specific instruments tailored to particular tooth surfaces.

Below is a detailed breakdown of the major curette types, their features, and their clinical applications.

1. Universal Curettes

Universal curettes are versatile instruments designed to be used on all tooth surfaces, both anterior and posterior. They have a semicircular cross-section with two cutting edges per blade and a blade face that is perpendicular (90°) to the terminal shank. This design allows clinicians to adapt the instrument to multiple areas without switching tools frequently.

They are commonly used for supragingival and subgingival scaling, particularly during routine prophylaxis and initial periodontal therapy. Proper technique involves maintaining correct angulation (approximately 70°) and using controlled, overlapping strokes.

Universal curettes are relatively easy to learn, making them ideal for general dentists and hygienists. Cleaning and maintenance include thorough ultrasonic cleaning, sterilization, and regular sharpening to preserve cutting efficiency.

Sub-types of Universal Curettes

Universal curettes are a broad & diverse category, so the following classification will help clarify the differences among the various sub-types:

·       Columbia Universal Curettes – Broad-bladed universal curettes designed for efficient removal of heavy calculus on both anterior and posterior teeth.

·       Barnhart Universal Curettes – Feature a slightly thinner blade and longer shank, allowing improved access to posterior regions and moderate subgingival deposits.

·       McCall Universal Curettes – Heavier, more rigid instruments commonly used for removing tenacious supragingival and shallow subgingival calculus.

·       Younger-Good Universal Curettes – Slimmer and more delicate than traditional designs, offering enhanced tactile sensitivity for fine scaling.

·       Langer Universal Curettes – Combine a universal blade with a Gracey-style shank, improving posterior access while retaining dual cutting edges.

·       Jacquette-Style Universal Curettes – Straight-shank instruments primarily used for anterior teeth and easily accessible surfaces during routine scaling.

The Safco universal curettes come in multiple types, including the ones discussed above, making it easy to select the ideal curettes for your procedures.

2. Gracey Curettes

Gracey curettes are area-specific instruments designed for precise subgingival scaling and root planing. Unlike universal curettes, they have only one cutting edge per blade, and the blade face is offset at approximately 70° to the terminal shank. This unique angulation allows optimal adaptation to specific tooth surfaces without excessive wrist manipulation.

Different Gracey numbers correspond to specific areas of the mouth (e.g., Gracey 1/2 for anterior teeth, 11/12 for mesial posterior surfaces, and 13/14 for distal posterior surfaces). They are especially effective in deep periodontal pockets and complex root anatomy.

Because of their precision design, Gracey curettes require careful handling and regular sharpening using manufacturer-recommended techniques. Proper storage and inspection help extend instrument lifespan.

3. After Five Curettes

After Five curettes are modified Gracey curettes designed for deeper periodontal pockets, typically greater than 5 mm. They feature a longer terminal shank — approximately 3 mm longer than standard Gracey curettes — and a thinner blade, allowing improved access into deep pockets without tissue distension.

Clinically, they are used for advanced periodontal therapy and maintenance in patients with moderate to severe periodontal disease. Their extended reach reduces the need for excessive lateral pressure, improving clinician comfort and patient outcomes.

Cleaning and maintenance follow the same protocols as Gracey curettes, with added care to protect the thinner blade during sharpening.

4. Mini and Micro Mini Curettes

Mini and Micro Mini curettes are further refinements of Gracey designs, featuring shorter blade lengths and, in the case of Micro Minis, significantly thinner blades. These instruments are specifically intended for narrow periodontal pockets, furcations, and areas with tight tissue adaptation.

Their reduced blade size enhances tactile sensitivity and precision, making them ideal for periodontal maintenance and implant debridement (when indicated). Because of their delicate structure, clinicians must use light, controlled strokes and avoid excessive force.

Proper cleaning, gentle handling, and careful sharpening are critical to prevent blade distortion or breakage.

5. Implant Curettes

Implant curettes are designed for cleaning and maintaining dental implants without damaging the implant surface. They are commonly made from plastic, titanium, or resin materials rather than stainless steel.

These curettes are used to remove biofilm and soft deposits around implants while preserving the integrity of the implant coating. Structural features include non-abrasive edges and softer materials to prevent scratching.

Cleaning protocols depend on the material but typically involve gentle ultrasonic or manual cleaning and low-temperature sterilization methods when required.
