Dentist offices going green

(NBC) - A dentist's office can generate a lot of waste. In one year a single office can generate 40,000 pieces of plastic. One Chicago office is trying to change that.

The Ora Dental Studio is located in a Leed certified "green building" and workers use tools from Hu-Friedy. The company launched it's Environ-Dent line 15 years ago.

Used dental instruments are sent back to the company, which then recycles them for use in other metal products.
