An In-Depth Guide to Basic Dental Instruments: Understanding their Functions

Are you afraid to go to the dentist because of the unfamiliar tools they use? If so, you’re not alone. Many people avoid the dentist because they’re afraid of the dental instruments. However, dental tools play a crucial role in maintaining our oral health. In this article, we will provide an in-depth guide that will help you understand the functions of basic dental instruments used by dentists and hygienists.


Dental instruments come in all shapes and sizes, each with its own specific purpose. Here are some of the basic dental instruments and their functions:


Mirrors are one of the most basic dental instruments used during an oral examination. They allow dentists and hygienists to see and examine the teeth and gums at different angles that would otherwise be difficult to see with the naked eye. Mirrors also help identify cracks, decay, and other dental problems.


Probes are used to measure the depth of periodontal pockets around teeth. They are thin and pointed instruments that are gently inserted into the space between the teeth and gums to check the health of the gums.


Scalers are used to remove dental calculus or tartar buildup from the teeth. This buildup is caused by plaque that has hardened over time, and can only be removed with specialized tools like scalers. There are various types of scalers available for specific areas of the mouth.

Dental Tray

Dental trays are used to organize instruments during dental procedures. They ensure all required tools are readily available and at arm’s reach for the dentist or hygienist.

Cotton Faucet

Cotton faucets are used to transport materials in and out of the oral cavity. They are made of cotton and are used to absorb saliva and excess water during dental procedures.

Periodontal Probe

Periodontal probes are used to measure pocket depth around teeth. The probe is inserted into the space between the gums and tooth in order to identify gum disease or other dental problems.

Examination Set

An examination set is a basic dental instrument kit that includes a mirror, explorer, faucet, cotton wool, and tweezers. It is a comprehensive kit used during routine dental exams.

Saliva Evacuators

Saliva evacuators are used to remove saliva from the oral cavity. They come in both high-velocity and slow-speed versions and are commonly used during dental procedures.

Ultrasonic Scaler Units

Ultrasonic scaler units are used to remove dental calculus or tartar buildup from teeth. They use high-frequency vibrations and specialized tips to remove hardened plaque. They are a modern alternative to traditional hand scalers.

Accurate and Single Scalers

Accurate and single scalers are used for root planing and removing deposits. They are made of high-quality steel and are ergonomically designed for a comfortable grip during use.


Dental instruments are essential for oral health and help dentists and hygienists provide effective treatment. Understanding the function of basic dental instruments can help you overcome dental anxiety and make you feel more comfortable during dental procedures.
