While there are no specific regulations from official governing bodies such as the CQC that explicitly prohibit dental nurses from wearing false eyelashes, it does state in the National Infection Prevention and Control Manual for England that eye or face protection should not be impeded by false eyelashes1, so it ultimately comes down to the individual practice's policies and professional judgment.
Dental professionals are expected to maintain a high standard of hygiene and infection control to ensure patient safety. Some dental clinics may have policies that restrict or discourage the use of false eyelashes or other cosmetic enhancements that could potentially interfere with strict infection control protocols. This is because false eyelashes may harbor bacteria or interfere with the proper fit and seal of personal protective equipment (PPE), such as masks or safety goggles.
It is advisable for dental nurses to check with their employer or follow the guidelines and policies set by their dental practice regarding the use of false eyelashes or any other cosmetic items. Adhering to the established protocols ensures that patient safety and infection control standards are upheld.
