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
- 44% of dental patients report being concerned about environmental impact related to healthcare services (including dental)
- 1,430,000 metric tons of CO2e were estimated from dental care waste in the U.S. in 2019
- 3% of total U.S. greenhouse gas emissions were estimated to come from the healthcare sector in 2018 (including dentistry within healthcare)
- 10.4% of all healthcare waste generated in the U.S. was identified as infectious waste in a 2012 study (relevant because dentistry generates regulated waste)
- 32% of healthcare organizations reported using renewable energy in their operations in 2023
- In 2023, ISO 14001 accounted for 402,000 certifications globally (environmental management systems capacity relevant to healthcare)
- The EU Medical Devices Regulation (MDR) includes requirements affecting lifecycle management; MDR entered into application in May 2021
- The global dentistry market was about $40.1B in 2023 for dental care services (context for sustainability investment base)
- The global dental instruments market was $7.9B in 2023
- The global dental implants market reached $5.7B in 2023
- $1.1M average annual savings potential per large multi-site provider from optimized waste and procurement in 2021 modelling (healthcare benchmark includes dental sites)
- The cost of treating improperly managed healthcare waste can increase by 2–3x compared with correctly segregated waste (WHO guidance)
- 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.
