Gracey Curettes: Numbers and their Uses
Gracey curettes play an important role in dental hygiene. Manufacturers specially design them to clean teeth thoroughly, particularly in deep gum areas where bacteria often hide. This guide explains what Gracey curettes are, how their numbering system works, and how dental professionals use them. Whether you are a dental student, hygienist, or simply curious about dental tools, you will find this article useful for gaining a better understanding of these instruments.
A Tool for Scaling and Root Planing
Dentists and hygienists use Gracey curettes as hand instruments specifically for scaling and root planing. These tools effectively remove plaque and tartar from the surfaces of teeth and roots. Unlike universal curettes, which dental professionals can apply to any area of the mouth, Gracey curettes target specific tooth surfaces. Moreover, their unique unique shape and angulation allow professionals to access hard-to-reach spots with ease. Dr. Clayton Gracey developed the Gracey curettes, and practitioners now widely use them in periodontal therapy. They are particularly effective for treating gum disease by cleaning deep pockets around the teeth.
How Are Gracey Curettes Different From Universal Curettes?
Gracey curettes have a distinctive design that sets them apart from universal curettes.
- Blade Angle: The blade of a Gracey curette is offset at 70 degrees to the shank. This design allows the blade to adapt perfectly to the tooth surface.
- One Cutting Edge: Each Gracey curette has only one cutting edge that is used for scaling. This feature ensures precise cleaning with minimal tissue trauma.
- Area-Specific: Unlike universal curettes, which can clean all areas, Gracey curettes are designed for specific parts of the mouth.
Gracey Curette Numbering and Their Specific Uses
Gracey curettes are numbered to indicate their intended use. Let’s break down the numbers and their specific applications:
1. Gracey 1/2 and 3/4
- Use: These curettes are used on the front teeth, also known as anterior teeth.
- Purpose: They are designed to clean the mesial (toward the midline) and distal (away from the midline) surfaces of these teeth.
- Why They Are Useful: The small size and simple design make them ideal for cleaning narrow areas around the front teeth.
2. Gracey 5/6
- Use: Primarily for anterior teeth but can also be used on premolars.
- Purpose: It is effective for cleaning the entire surface of these teeth, especially in cases of mild gum disease.
- Why They Are Useful: Its versatile design allows it to work on both front and premolar teeth.
3. Gracey 7/8 and 9/10
- Use: These curettes are designed for the back teeth, known as posterior teeth, and are mainly used on the buccal (cheek-facing) and lingual (tongue-facing) surfaces.
- Purpose: They excel at cleaning wide, flat surfaces.
- Why They Are Useful: Their angulation makes it easy to clean the outer and inner sides of the molars and premolars.
4. Gracey 11/12
- Use: This curette is used for the mesial surfaces of posterior teeth.
- Purpose: It reaches into deep gum pockets on the side of the molars and premolars.
- Why They Are Useful: Its unique design ensures efficient cleaning of areas that are hard to access with other instruments.
5. Gracey 13/14
- Use: Ideal for cleaning the distal surfaces of posterior teeth.
- Purpose: It removes tartar and plaque from the back corners of molars.
- Why They Are Useful: This curette’s shape allows for precision cleaning in tricky areas.
6. Gracey 15/16 and 17/18
- Use: These are newer additions to the Gracey family, designed for advanced scaling.
- 15/16: Used for mesial surfaces of posterior teeth but with improved access and angulation.
- 17/18: Designed for distal surfaces of posterior teeth with better reach for extreme angles.
- Why They Are Useful: They enhance the range and efficiency of scaling in complex cases.

How to Use Gracey Curettes Correctly
Using Gracey curettes requires proper technique. Here are the key steps:
- Identify the Correct Curette
Choose the appropriate Gracey curette based on the tooth surface you are cleaning. - Position the Curette
Hold the instrument with a modified pen grip and ensure the cutting edge is properly adapted to the tooth surface. - Apply the Right Pressure
Use gentle but firm strokes to remove plaque and tartar. Avoid excessive force to prevent gum damage. - Follow a Systematic Approach
Work in sections, starting with the front teeth and moving to the back.
