In modern dental clinics, dental handpieces are among the most frequently used instruments. Their cleanliness directly affects treatment quality, patient safety, and equipment lifespan. Learning how to clean a dental handpiece correctly is essential for every dental professional.
In this guide, we share practical and professional methods to help clinics maintain handpieces in excellent condition.
Why Proper Handpiece Cleaning Matters
During daily dental procedures, handpieces are exposed to blood, saliva, plaque, and bacteria. Without proper cleaning and sterilization, these contaminants can lead to cross-infection and equipment damage.
Regular cleaning helps to:
-
Prevent bacterial and viral transmission
-
Maintain stable rotation and cutting efficiency
-
Extend equipment lifespan
-
Reduce maintenance costs
-
Comply with international hygiene standards
When Should Dental Handpieces Be Cleaned?
To ensure safety and performance, dental handpieces should be cleaned:
-
After every patient treatment
-
Before sterilization
-
At the end of each working day
Immediate cleaning after use is strongly recommended.
Step-by-Step Guide: How to Clean a Dental Handpiece
Step 1: Disconnect the Handpiece
After treatment, turn off the air and water supply and carefully remove the handpiece from the dental unit.
Step 2: Clean the External Surface
Wipe the handpiece with a medical-grade disinfectant wipe or soft cloth to remove visible contamination.
Avoid abrasive materials or corrosive chemicals.
Step 3: Remove the Bur and Clean the Head
Always remove the bur before cleaning.
Use a soft brush to clean the chuck and head area, where debris often accumulates.
Step 4: Internal Cleaning and Lubrication
Internal parts are sensitive to moisture and debris.
Use a professional handpiece maintenance spray:
-
Insert the nozzle into the drive air hole
-
Spray for 2–3 seconds
-
Allow residue and contaminants to flow out
This process cleans and lubricates internal components.
Step 5: Run the Handpiece
Reconnect the handpiece and run it for 20–30 seconds to remove excess lubricant and stabilize rotation.
Step 6: Autoclave Sterilization
After cleaning and lubrication, sterilize the handpiece using a Class B autoclave.
Recommended settings:
-
Temperature: 134°C
-
Time: 3–5 minutes
Follow the manufacturer’s instructions carefully.

Avoid these frequent errors:
❌ Skipping lubrication
❌ Using ultrasonic cleaners without approval
❌ Soaking in disinfectant liquid
❌ Sterilizing without cleaning
❌ Using compressed air for internal drying
These practices can seriously damage handpieces.
