Why Airotor Handpieces Make Noise: Understanding the Cause

 Why Airotor Handpieces Make Noise: Understanding the Cause

Airotor handpieces are known for their high-speed performance, but excessive or unusual noise is a warning sign that something may be wrong. Here's why your handpiece might be getting noisier than usual:

1. Worn or Damaged Bearings

The most common reason is worn-out bearings in the turbine. As they degrade, they cause friction and imbalance, leading to a louder, rougher sound.

2. Lack of Lubrication

Inadequate or irregular oiling can cause the moving parts to run dry, resulting in high-pitched or grinding noises. Regular maintenance is essential.

3. Damaged or Bent Bur

A bur that’s not straight or properly balanced can cause vibration and noise during rotation. Always use high-quality, straight burs.

4. Turbine Cartridge Issues

If the turbine is loosely fitted or misaligned, it can rattle during operation, making unusual sounds.

5. Debris or Contamination

Dust or particles inside the head can interfere with the turbine, increasing friction and noise.

Tip: If your handpiece becomes noisier over time, don't ignore it. Routine maintenance or a turbine replacement can bring back quiet, smooth performance.

A well-maintained airotor should have a consistent, humming sound—not a loud or erratic one. Pay attention to the noise—it’s your handpiece asking for care!
