Question: What should I do if the dental handpiece bur easily falls off?

Answer: The bur is too loose and easy to fall off. You can start with the following 4 aspects.

1. When selecting a bur, you must confirm the allowable speed range specified by the bur manufacturer, otherwise the bur will easily fall off when the cutting load is greater than the clamping force of the chuck.

2. The mini handpiece should use a short bur, which is easy to fall off when attaching a long bur.

3. Do not use worn-out burs, curved burs, and burs with missing edges, otherwise it will affect the durability of the bearing.

4. After the bur is installed, the bur must be pulled out to confirm that it is firmly installed. If it is not inserted deep or inserted too shallow, it will cause the danger of the bur flying out.
