Impact of SARS-CoV-2 on Dental Practice: A Comprehensive Narrative Review

Aim This narrative review examines the impact of SARS-CoV-2 on dental practice, integrating evidence on transmission pathways, infection control, oral manifestations, vaccination, and long-term clinical and operational implications. Materials and Methods A comprehensive literature search was conducted across PubMed, Scopus, Web of Science, and Cochrane Library, covering studies published between 2020 and 2025. Eligible studies addressed viral transmission within dental settings, infection-prevention strategies, clinical presentations, vaccination attitudes, and professional guidelines. Data were synthesized qualitatively and organized thematically to reflect the multidimensional impact of the pandemic. Results SARS-CoV-2 RNA was detected in the saliva of over 90% of infected individuals, while 40–45% of cases remained asymptomatic. The use of extraoral suction systems reduced aerosol contamination by up to 90%, and rubber dam application lowered aerosol generation by 80–99%. Oral manifestations occurred in 45–68% of patients, with dysgeusia being the most prevalent (45%). Vaccination acceptance among dental professionals reached 81%. However, healthcare workers still exhibited a high prevalence of long COVID (78%). Economic data indicated that 97% of dental practices closed except for emergencies during peak pandemic periods, while Croatian studies documented a 30.27% reduction in patient visits. The crisis also accelerated the global adoption of teledentistry for consultation and triage. Conclusions SARS-CoV-2 profoundly affected dental practice. Sustained implementation of infection-control protocols and adequate personal protective equipment remains essential, while persistent oral sequelae, such as taste disorders, require ongoing clinical monitoring.
