Face Shields: Do We Need Them?


The last few months have brought many changes on how the world operates. Dental offices are no exception. In our office, we wear extra gear, such as wearing mask at all times, disposable jackets, hair bouffant cap, gloves and etc.

According to a recent article in the The Wall Street Journal: “With face shields a growing part of hospital protocol, some infectious disease doctors are calling for greater adoption outside the medical setting.”

You may wonder, how does a face shield offer protection from COVID-19? Let’s understand how one gets infected with COVID-19. This virus spreads through droplets that are released into the air from an infectious person when they cough, sneeze or talk. The mouth, nose and the eyes are potential areas of how the virus can get into your system. Masks protect your mouth and nose, but what about the eyes?



According to the vice president of the Infectious Diseases Society of America and an infectious disease physician Dr. Daniel McQuillen, “If someone coughs and it catches your eyes, you are going to get the infection.” This is where a face shield comes into play. Unlike masks, face shields protect not only the mouth and nose but your eyes as well.

Face shields cover the face more than a mask, so droplets are less likely to land near the eyes, nose or mouth. Though scientists haven’t ruled the face shield as being superior to masks, there are some benefits, for example:

1.       Easier to wear for prolonged periods of time.
2.       You’re least likely to touch your face
3.       There’s more coverage to the face
4.       Reusable
5.       Easy to clean

Another question arises: should one wear a mask under the face shield? Most scientist and doctors are split in deciding what the correct answer is for this question. Some believe that the face shield is enough to prevent infection. Others believe that the face shield has its cons, such as the potential of droplets going in from the sides. In certain settings, some believe that it’s always a good idea to take extra precaution. In our office, we’ve decided to be extra cautious and just wear the mask under the face shield.

Brush (and floss) your teeth!

In the recent Mayo Clinic Health Letter , (Volume 37, Number 4) there was an interesting article on how tooth brushing reduces cardiovascular risks. The article states: Brushing your teeth twice daily is important for maintaining good oral hygiene. This daily routine can also benefit your heart. A study presented at the 2018 American Heart Association Scientific Sessions provides new evidence of this link. The study's 682 participants self-reported their tooth-brushing habits compared with the recommendation of twice a day for at least two minutes each time. Over an average of 28 months of follow-up, those who reported brushing their teeth less frequently and for a shorter duration had three times the risk of a first major cardiovascular event than did those who met the tooth-brushing guidelines. These cardiovascular events included heart attack, stroke, hospitalization for heart failure or dying of a cardiovascular cause. A separate study, published in the December 2018 i...

CBCT Scan: Maxillary Resorption by Tooth #1

Despite years of training and practice, it has been difficult to correctly diagnose what can barely be seen on 2-D intra-oral images. The  Kodak 3D extra oral imaging (CBCT) shows the whole picture from the axial, coronal, and sagittal views. CBCT provides additional information that is essential when used in Endodontics for finding evidence of resorption .  This patient was diagnosed with pain in the maxillary right area. The patient was sent to this office for root canal therapy on tooth 2. Ordinary radiographs did not show a clear picture of the area. A CT was taken and the results show resorption of tooth #2 by tooth #1. Clearly the prognosis is poor. CT scans are recommended to diagnose the relationship of tooth #1 in relationship to tooth #2.   If you're in any doubts as to the prognosis of your patient's tooth, please let us help you save a tooth.

If Your Teeth Could Talk...More Information

If Your Teeth Could Talk... Following up with more information from a blog post on December 30, 2016 of an article by The Wall Street Journal published on December 27, 2011  written by Melinda Beck. An oral history: A dental exam can reveal some telltale signs of broader health problems. Teeth Front: Don't be fooled by very white teeth. Many oral health problems may be lurking unseen.  Tops of back molars: Worn, flattened surfaces indicate stress-related clenching and grinding.  Back of uppers: Area where stomach acid had worn away enamel could indicate bulimia. Gums Red, puffy and inflamed gums are common during pregnancy. Tiny red hemorrhages with spontaneous bleeding may indicate leukemia. Periodontal disease, in which gums pull away from the teeth, can signal diabetes, cardiovascular problems and respiratory diseases.
