Even with modern dentistry growing fast, the environmental footprint is still hitting real nerves. In 2023, 44% of dental patients said they are concerned about the environmental impact of healthcare services, while dentistry in the US was linked to an estimated 1,430,000 metric tons of CO2e from waste in 2019. The tricky part is what most people assume is “small scale” adds up across regulated infectious waste, procurement and energy use, and the materials that make up restorations.
Key Takeaways

- In the U.S., medical waste disposal costs averaged $0.06–$0.10 per pound depending on treatment method (benchmarked in industry guidance)
- EU dental professionals generated an estimated 3.4–4.9 kg of waste per patient contact on average in a 2018 life-cycle and waste assessment
- Thermal disinfection of instruments produces less waste than chemical methods when optimized, reducing effluent volume by up to 50% in lab-scale evaluations (instrument processing evidence)
Dental care can cut emissions with better waste segregation, renewable energy, and efficient electrification.
