Extraoral Suction Systems in Every Exam Room

Clean Air with Suction Systems

Anyone who’s been to the dentist is probably familiar with the suction devices that dentists and hygienists place inside your mouth to collect water, saliva, blood, and debris during a procedure. These systems greatly reduce the amount of spray and splatter formed while you’re in the chair, but they can’t entirely prevent small particles from entering the air.

That’s why Hellertown Dental Group has installed an extraoral (“outside the mouth”) suction system from ADS Dental in every one of our exam rooms.

Air Suction System


Our new weapon in the war on Coronavirus:
The Terminator

This video clearly shows why ADS calls its extraoral suction system (EOS) the Droplets & Aerosols Terminator. The system collects droplets, dust and pathogens produced during routine dental procedures–also known as aerosol–through a suction mouthpiece hood. And what happens to that aerosol next would make the “other” Terminator proud.

Capture and Kill

Inside the ADS system, viruses, bacteria, and other particles are trapped in a 3 layered HEPA filtration system. Next, the air is dried using a precision water vaporization filter. Finally, the air passes through a medical grade UV-C light disinfection system, which irradiates and kills any remaining pathogens.

The CDC recommends “high-efficiency particulate air (HEPA) filtration unit while the patient is undergoing, and immediately following, an aerosol generating procedure.” In addition to the air filtration systems already in use, the EOS systems at Hellertown Dental Group have been proven effective in reducing both the frequency and intensity of contamination in dental operatories.1,2

What Our Patients Are Saying

In our 25 years of practice, we’ve seen thousands of patients. How can we help you?

  • I came in and I ended up having 3 cavities. She then showed me how to prevent them in future and how to just maintain healthy teeth. She’s super outgoing, super easy to get along with, never awkward, always so talkative, interested about everyone’s life. The kids center is a big plus.

  • I sit in the big chair, and then they get the mirror thingy and they look at my teeth. When they use the Tinkerbell light, it didn't hurt at all. I like it when my teeth are bright and shiny when I leave. I really like coming to see Doctor Ann.

  • I’ve been coming here for about 16, 17 years, and all of my kids from elementary through high school, and even in college have come and we’ve all had the same experience. They are pleasant. They get to know you. They would always explain to me the proper way to floss, and the particular type of flosses to use.

  • There’s always a level of comfort. As you’re sitting in the waiting room, you don’t feel like you’re bored out of your mind. It’s a nice, comfortable environment. The same when you get back in the chair. The TV’s going, and it makes you feel a little bit more at home.
