Why Is My Handpiece Not Working

A dental handpiece is a pivotal tool used by dentists and dental hygienists in the delivery of dental care services. It is an instrument that is designed to rotate dental burs, allowing the removal of dental tissues such as enamel, dentin, and other soft tissues. Brands like Kavo, NSK, W&H, Sirona, Brasseler USA, Star Scican, Lares, and MK Dent are examples of well known dental handpiece manufacturers.

However, it is not uncommon for dental handpieces to stop working, and this can be frustrating for both the dentist and the patient. In this article, we will explore some of the reasons why my dental handpiece may not be working.

Lack of Maintenance

Lack of maintenance is one of the most frequent causes of a dental handpiece not functioning. Dental handpieces need regular cleaning and lubrication to keep them functioning correctly. Failure to do this can result in debris, dirt, and other contaminants building up in the handpiece, which can affect its performance. Lack of maintenance can also cause the bearings and other components to wear out faster, leading to premature failure of the handpiece.

Poor Quality Components

The usage of subpar components is another factor that could be causing a dental handpiece to malfunction. Dental handpieces are made up of various components, including bearings, turbines, and rotors. The use of low-quality components can lead to premature failure of the handpiece. It is essential to use high-quality components when repairing or replacing parts of the handpiece.

Air Pressure Issues

Compressed air is necessary for dental handpieces to operate properly. The performance of the handpiece may be impacted by excessively low or excessively high air pressure. Low air pressure may cause the handpiece to operate more slowly or not at all. Excessive air pressure might harm the handpiece and cause an early failure.

Blockages

Blockages in the water lines or airlines can also cause a dental handpiece to stop working. Blockages can be caused by debris or other contaminants in the water or air supply. These blockages can affect the flow of water or air to the handpiece, leading to reduced performance or complete failure.

Worn Bearings

The bearings in a dental handpiece are designed to allow the handpiece to rotate smoothly. Over time, these bearings can wear out, leading to reduced performance or complete failure. Worn bearings can cause the handpiece to vibrate or make a loud noise when in use. If the bearings are not replaced, it can lead to further damage to the handpiece.

Damaged Turbines

The turbine is one of the critical components of a dental handpiece. It is responsible for the rotation of the dental bur. Damage to the turbine can cause the handpiece to stop working or reduce its performance. Turbines can be damaged by a lack of maintenance, poor quality components, or general wear and tear.

Electrical Issues

Some dental handpieces are powered by electricity. If there is an issue with the electrical supply to the handpiece, it can cause it to stop working. Wiring or the power supply itself may be at fault for electrical problems. It is crucial to make sure that the handpiece's electrical components are routinely inspected and maintained.

Conclusion

A dental handpiece is an essential tool in the provision of dental care services, to sum up. Nonetheless, it is fairly common for dental handpieces to quit working. A dental handpiece may not be functioning for a variety of reasons, such as improper maintenance, subpar parts, problems with air pressure, obstructions, worn bearings, damaged turbines, and electrical problems. Proper maintenance and the use of high-quality components can help prevent many of these concerns. Also, it is crucial to guarantee that the handpiece is routinely inspected and maintained by a trained technician.
