How a Microbiologist Turned Dentist Is Keeping Patients Safe

Before Dr. John Siu of The Dental People went to dental school, he completed his undergraduate degree in microbiology. During his studies, he gained a rich knowledge of viruses, bacteria, and other organisms that are too small to be seen with the naked eye. Today, he is still putting that knowledge to work! The safety measures he has implemented in our practice aim to minimize the risk that COVID-19 — or any other dangerous microbes — will harm our patients or our team members. Thanks to the precautions we have in place, we can answer the question, “Is the dentist safe?” with a resounding yes! This blog post explains a few key parts of our practice’s safety protocol.

Negative Pressure Rooms

Have you ever seen a medical drama where a sick patient gets put in an isolation room? Isolation rooms are also known as negative pressure rooms. They are called that because the pressure inside the room is lower than the pressure outside of it. That means when the door is opened, non-contaminated air can flow in, but the contaminated air doesn’t flow out. The negative pressure rooms in our practice ensure that any bio-aerosols released during procedures do not endanger anyone outside the room. Not many practices have negative pressure rooms, but we are proud that we have invested in them!

Two HEPA Filters in Every Room

HEPA stands for High Efficiency Particulate Air. HEPA filters remove 99.97% of particles from the air that are 0.3 microns in size — that’s the size of particle that tends to evade other types of filters. While many practices have a HEPA filter in each room, we do not want to take any chances. That is why we have two HEPA filters in each room: one in our central HVAC system and one as a standalone air filter.

Strict PPE Protocols

Personal protective equipment, PPE, is essential for medical and dental professionals because we interact so closely with the public. Some of the PPE that we use include:

  • N95 and ASTM Level 3 masks
  • Face shields
  • Disposable coats and hats

We also strongly encourage our patients to make wise PPE decisions. For example, we do not allow patients to wear gloves in our practice because we wish to reduce the risk of cross contamination.

Diligent Sanitization, Sterilization, and Hygiene

Dental practices have always been some of the cleanest places in the country, and that is truer now than ever. We thoroughly sterilize our instruments, clean the operatories after every appointment, perform a deep cleaning every evening, and expect our team members to adhere to high standards of hygiene.

There is no need to be worried about visiting the dentist during COVID-19. Strict safety measures are in place to protect you.

More About Dr. Siu

Dr. Siu earned his Bachelor of Science in Microbiology and Immunology from the University of British Columbia before he attended dental school at the prestigious Boston University School of Dental Medicine. Since he graduated Summa Cum Laude, he has continued to further his education by taking courses in dental implants, sedation dentistry, periodontics, and more. He enjoys forming trusting, long-lasting relationships with patients. To learn more about Dr. Siu, the other doctors in our practice, or our safety protocol, contact our team at 281-769-7648.
