Dental instruments are essential tools used by dentists to examine, manipulate, restore, and extract teeth and to surround oral structures. Dental instruments come in different shapes, sizes, and materials and are used for various dental procedures. In this article, we will discuss the types, uses, and maintenance of dental instruments.

Types of Dental Instruments

Dental instruments can be classified into various categories depending on their functions. Here are some of the most common types of dental instruments:

Examination Instruments

Mouth mirror
Periodontal probe

Restorative Instruments

Dental handpieces
Composite placement instruments

Surgical Instruments


Endodontic Instruments

Endodontic handpieces

Orthodontic Instruments


Periodontal Instruments

Periodontal knives
Gingival margin trimmers

Uses of Dental Instruments

Dental instruments are used for various purposes, depending on their types. Here are some of the most common uses of dental instruments:


Examination instruments are used to examine the oral cavity, teeth, and surrounding structures. The mouth mirror is used to reflect light and provide a clear view of the teeth and mouth. The explorer is used to detect cavities, calculus, and other irregularities in the tooth surface. The periodontal probe is used to measure the depth of the periodontal pockets and assess the periodontal status. Tweezers are used to hold and manipulate small objects and materials.


Restorative instruments are used to restore the form, function, and aesthetics of the teeth. The dental handpiece is used to remove the decayed tooth structure and prepare the cavity for the filling. Excavators are used to removing soft and hard tissues from the cavity. Condensers are used to pack and condense the filling material into the cavity. Burnishers are used to smooth and polish the filling material. Composite placement instruments are used to place and shape composite resin filling material.


Surgical instruments are used to perform surgical procedures in the oral cavity. Forceps are used to grasp and extract teeth. Elevators are used to elevate and loosen the tooth from the socket. Scissors are used to cut soft tissues. Retractors are used to retract soft tissues and provide better access and visibility. Hemostats are used to control bleeding.


Endodontic instruments are used to perform root canal treatment. Endodontic handpieces are used to prepare the root canal for filling. Files are used to remove the pulp tissue and shape the root canal. Reamers are used to enlarge and smooth the root canal. Broaches are used to remove debris and pulp tissue from the root canal. Spreaders are used to spread the filling material into the root canal.


Orthodontic instruments are used to diagnose, prevent, and treat malocclusion and other dental and skeletal abnormalities. Pliers are used to grip and manipulating wires and brackets. Cutters are used to cut and remove wires and brackets. Separators are used to create space between teeth.


Periodontal instruments are used to diagnose and treat periodontal disease. Curettes are used to remove plaque, calculus, and other debris from the teeth and gum line. Scalers are used to remove plaque, calculus, and stains from the tooth surface. Chisels are used to remove bone and reshape the tooth socket. Periodontal knives are used to incise and excise soft tissues. Gingival margin trimmers are used to trim and shape the gingival margin.

Maintenance of Dental Instruments

Dental instruments need proper maintenance to ensure their longevity, effectiveness, and safety. Here are some tips for maintaining dental instruments:
  • Clean the instruments immediately after use to prevent debris and stains from drying and hardening on the surface.
  • Use a cleaning solution that is safe and effective for the instrument material and type.
  • Rinse the instruments thoroughly with water to remove all traces of the cleaning solution.
  • Dry the instruments completely before storing them to prevent rust and corrosion.
  • Store the instruments in a dry and clean place to prevent contamination and damage.
  • Sharpen the instruments regularly to maintain their cutting ability and precision.
  • Inspect the instruments regularly for signs of wear, damage, or malfunction and repair or replace them as needed.


Dental instruments are vital tools used by dentists to provide quality dental care. They come in various types, sizes, and materials and are used for different dental procedures. Proper use and maintenance of dental instruments are essential to ensure their effectiveness, safety, and longevity. By following the tips for instrument maintenance, dental professionals can prolong the life of their instruments and provide quality dental care to their patients.

What is the difference between a scaler and a curette?

A scaler is used to remove plaque and calculus from the tooth surface, while a curette is used to remove plaque and calculus from the gum line and tooth root.

How often should dental instruments be sharpened?
Dental instruments should be sharpened regularly, depending on their frequency of use and the type of material they are made of.

How can I prevent my dental instruments from rusting?
To prevent dental instruments from rusting, make sure to dry them completely before storing them and store them in a dry and clean place.

Can dental instruments be autoclaved?
Yes, most dental instruments can be autoclaved, but it is important to follow the manufacturer's instructions and guidelines for proper sterilization.

What should I do if I notice signs of wear or damage on my dental instruments?
