Dental Excavator: Everything You Need to Know About This Essential Tool for Effective Teeth Cleaning

Dental excavators are essential tools used by dentists and dental hygienists to remove decay, caries, and tartar from teeth. They are precision instruments that require skill and training to use effectively. Without these tools, dental procedures such as fillings and restorations would not be possible. In this blog post, we will explore the different types of dental excavators, their uses, and how to properly maintain them. Whether you are a dental professional or a curious patient, this post will provide you with valuable information about this important dental tool.

Composition of Dental Excavator

Dental excavators are typically made of high-quality stainless steel, which is a durable and corrosion-resistant material that can withstand repeated use and sterilization. The handle of the excavator is usually made of a non-slip material, such as silicone or rubber, to provide a secure grip and prevent slipping during use.

The excavator blade is the working part of the tool and comes in different shapes and sizes depending on the type of excavator. The blade is typically thin and sharp, allowing the dental professional to remove decay, caries, or other debris from the tooth surface. The blade is attached to the handle using a shank, which is also made of stainless steel and is designed to fit securely into the handle.

Overall, the composition of dental excavators is designed to provide maximum durability, ease of use, and precision during dental procedures. The quality of the materials used ensures that dental excavators can withstand repeated sterilization and use without becoming damaged or losing their sharpness.
