Dentists, by nature, are at high risk of exposure to infectious diseases. The emergence of COVID-19 has brought new challenges and responsibilities to dental professionals. A better understanding of aerosol transmission and its implication in dentistry can help us identify and rectify negligence in daily dental practice. In addition to the standard precautions, implementation of special precautions could prevent disease transmission from asymptomatic carriers. These special precautions would not only help control the spread of COVID-19 but also serve as a guide for managing other respiratory diseases. Understanding the role of dental environments in COVID-19 transmission may have a positive impact in the prevention of infection. Workplaces as well as home environments must be considered at risk. In order to decrease the possibility of contagion, it will be necessary to keep sanitized the work environments and sterile the instruments, taking the right precautions in the management of patients and operators.Even paying attention to home devices for daily oral hygiene might have a positive impact on maintaining individual health and lower the chances of spreading the infection.
