Core Responsibilities

Primary Functions

Perform comprehensive patient assessments by reviewing medical/dental history, taking vital signs, assessing risk factors for oral disease, and documenting findings clearly and concisely in the electronic health record (EHR).
Complete full-mouth periodontal charting including probing depths, bleeding on probing, recession, mobility and furcation involvement, and use periodontal data to guide individualized treatment planning.
Deliver professional prophylaxis and periodontal therapy (scaling and root planing) for adults and adolescents, adapting techniques for patient comfort and clinical need while following current clinical guidelines and best practices.
Take, develop and interpret intraoral and extraoral dental radiographs (bitewings, periapicals, panoramic as applicable) in accordance with state laws and safety protocols; annotate and store images in the patient record.
Administer local anesthesia and nitrous oxide sedation monitoring, if licensed and certified in the state, and monitor patients’ responses throughout treatment.
Apply topical fluorides, dental sealants, desensitizing agents and adjunctive preventive materials to reduce caries risk and hypersensitivity, while documenting materials used and patient instructions.
Conduct oral cancer screenings and soft tissue exams, identify suspicious lesions, communicate concerns to the supervising dentist, and coordinate timely referrals.
Provide customized patient education and oral hygiene instruction — demonstrating brushing and interdental cleaning techniques, reviewing home care regimens, and using motivational interviewing to support behavior change.
Collaborate with the dentist to develop comprehensive treatment plans, communicate clinical findings and recommended interventions, and assist with case acceptance and sequencing of care.
Monitor and manage periodontal maintenance schedules and personalized recall systems to optimize long-term outcomes and patient retention.
Maintain accurate clinical and billing documentation using ADA procedure codes (CDT) and ensure compliance for insurance claims, government programs, and office policies.
Implement, follow and audit infection control protocols (sterilization, instrument processing, barrier techniques) according to CDC, OSHA, and state board guidelines to protect patients and staff.
Participate in chairside duties as required — including provisional chairside assistance, intraoral photography, taking impressions for study models, and fabricating/placing preventive restorations within scope.
Triage dental emergencies and acute conditions, provide immediate palliative care, coordinate dentist evaluation, and document emergency treatments and follow-up plans.
Use digital charting and practice management software to schedule appointments, confirm patient recalls, and maintain accurate treatment and financial records.
Maintain clinical supplies and equipment readiness — perform routine checks, report malfunctioning equipment, and assist with ordering and inventory control to ensure uninterrupted practice operations.
Mentor and supervise dental assistants and front-office staff on clinical protocols, infection control, radiography techniques, and patient communication to ensure consistent quality of care.
Participate in quality improvement initiatives including chart audits, patient satisfaction tracking, and implementation of evidence-based clinical protocols to improve outcomes and safety.
Stay current with continuing education requirements, new clinical modalities, state regulations and best practices; actively apply new knowledge to improve clinical services.
Educate patients about preventive health beyond dental care including nutritional counseling related to oral health, tobacco cessation interventions, and systemic health connections (diabetes, cardiovascular risk).
Ensure compliance with legal and regulatory requirements, maintain professional licensure (RDH) and certifications (CPR, radiography, local anesthesia where applicable), and document continuing education credits.

Secondary Functions

Assist with front-desk duties during busy periods: patient pre-screening, medical history updates, and insurance verification to support efficient patient flow.
Support community outreach programs, school sealant clinics and public health initiatives to increase access to preventive oral care and promote clinic services.
Contribute to marketing and patient retention efforts by participating in patient education content creation, social media initiatives and in-office events.
Help develop and maintain office clinical policies and emergency protocols, and participate in periodic staff training and mock drills.
Coordinate with supply vendors and the office manager on procurement of clinical materials, tracking usage patterns and suggesting cost-saving alternatives without compromising quality.
Assist dental team with implementing new digital tools (EHR modules, digital radiography, patient education software) and provide end-user feedback to improve workflows.
Participate in peer review and case-study discussions to support continuous clinical learning and to foster evidence-based practice adoption.
