How dangerous are Dental Aerosols?

Watch how dental aerosols contaminate the air and surfaces in this exclusive video.

Dental aerosols are some of the most dangerous contamination carriers in the dental working environment. Blood, nose and throat secretions, saliva, bacteria, and viruses can all become aerosolized during standard dental procedures or surgeries.

Not only is someone at risk of inhaling infectious particles, but these particles remain suspended in the air, settle on surfaces and are often re-aspirated.


In one study, bacteria levels in the air increased 6 to 20 times during treatments in both a multi-chair clinic and a closed operatory. Aerosols even spread over 30ft, into areas where there was no dental activity.

Bacteria was found in the air in an amount exceeding the proposed safe value, which created a potential risk both for doctor and patient.1

Streptococcus and Staphylococcus bacteria is prevalent in the air during dental surgery. Other studies indicate that 85-90% of these bacteria are Streptococcus bacteria typical for the oral cavity.2

Using an air purification system like VidaShield can significantly reduce potentially hazardous bioaerosols created during dental procedures.

Dental Installations

“I’m really proud of my facility and the protocols we have in place to maintain a safe and healthy environment, but I am always eager to do more to ensure the well-being of my patients and staff.”

“It was so incredibly easy to spec in. Everyone from the architects to the installers were very supportive of it. They said let’s try it and let’s see how it works.”
Matthew Garman, Project Manager, Community Health Outreach, Jacksonville, FL
“I’m very excited to hear about the lights. I do feel like it is a little more protection for my children.”
