A dental hygienist has applied for a job with piercings in her eyebrow, nose, and lip that she refuses to remove. As a dentist, you would likely not hire her because visible piercings could be unsanitary and distracting for patients. Healthcare providers with visible tattoos may also not be hired because tattoos could be unsanitary or unprofessional. Hair should be tied back, minimal jewelry worn, and good hygiene maintained to prevent contamination and prioritize patient comfort during medical procedures.
