Nasal rinses and mouthwashes, which directly impact the major sites of reception and transmission of human coronaviruses (HCoV), may provide an additional level of protection against the virus. In the experiment, performed by Craig Meyers and his colleagues and published in the Journal of Medical Virology (2020, Sep 17), the researchers created cells grown from human tissue and then infected them with HCoV. HCoV is a human coronavirus 229e played the role of a surrogate for SARS-CoV-2. They subjected the virus to several common, over-the-counter mouthwashes and rinses for 30 seconds, 1 minute, and 2 minutes, and measured how much of the virus was inactivated. The reported results were the following:

• Peroxide Sore Mouth (CVS), Orajel Antiseptic Rinse (Church & Dwight Co.), and 1.5% H2O2 (Cumberland-Swan) — all of which listed hydrogen peroxide as their active ingredient — inactivated less than 90% to as much as 99% of the HCoV, depending on contact time.

• Crest Pro‐Health (Proctor & Gamble) mouthwash inactivated 99.9% to more than 99.99% of the HCoV during all three contact times.

• Listerine Ultra (Johnson & Johnson Consumer), Equate (Wal-Mart Co.) and Antiseptic Mouthwash (CVS) inactivated less than 99.9% of the HCoV at 30 seconds.

• Listerine Antiseptic (Johnson & Johnson Consumer) mouthwash which, according to researchers, had the same or similar inactive ingredients as Listerine Ultra, Equate and Antiseptic Mouthwash inactivated more than 99.9% of the virus at 30 seconds.

However, per Hana Akselrod, MD, MPH, before we start telling our patients to use mouthwash to prevent the spread of the coronavirus, we still need to learn how mouthwashes, nasal rinses and sinus rinses would work in the nose, mouth and throat of individuals infected with COVID-19, not in a simulated environment. We also need to answer questions, like how long would you have to gargle with mouthwash, as well as how often would you have to gargle? Is it safe for people to use mouthwashes and nasal rinses for the purposes of preventing the spread of the coronavirus?



It is well known that dental visit expectation can be very stressful for many patients. While in the dental waiting room the mindfulness-based cognitive therapy (MBCT) can be practiced to reduce the visit apprehension.

One of the MBCT practices is a "breathing break". Our breath is a window into knowing and regulating our mind-body. When we breathe in, our heart rate goes up. When we exhale, our heart rate goes down. By having a longer exhalation than inhalation, we can slow our heart rate more, and we can also stimulate the vagus nerve. Breathing into our lower belly ( abdominal breathing) stimulates the sensory pathways of the vagus nerve that go directly to our brain, which has an even more calming effect.

Focus narrowly on the breath, and then expand awareness out to your full surrounding. 

Here is one of the versions of the breathing break:


1) Becoming aware: Sit upright and close your eyes. Connect with your breathing for long inhalation and exhalation. With this awareness, ask yourself, " What is my experience right now? What are my thoughts? Feelings? Bodily sensations?" Wait for responses. Acknowledge your experience and label your feelings, even if they are unwanted. Notice any pushing space for all that comes up in your awareness.


2) Gathering your attention: Gently direct your full attention to your breathing. Notice each inhalation and each long exhalation. Follow each breath, one after another. Tune in to a state of stillness, it will allow you to come from a place of being.


3) Expanding your awareness: Sense your field of awareness expanding around you. Notice your posture, your hands, your toes, your facial muscles. Soften any tension. Befriend all of your sensations, greet them with kindness. With this expanded awareness connect with your whole being, encompassing all that is you in the present moment.

X-rays help dentist to detect problems that would be missed by just looking in your mouth, such as:

 Xray Chin

1) cavities between teeth or under fillings

2) trouble with teeth and jaw development in children and teens

3) bone loss from gum disease

4) jaw bone tumors


Sometimes x-rays are needed as part of your dental treatment for diagnosis if you have tooth ache or in case of tooth fracture. 


Types of Dental X-rays


Common x-rays used in the dental office include bite-wing, periapical, and panoramic x-rays. Bite-wing x-rays help dentist check for tooth decay between the back teeth or under dental fillings. Periapical x-rays help dentist observe conditions below the gum line, showing the roots of the teeth and surrounding bone. Panoramic x-rays use a machine that rotates around the head. It produces a long film that shows the entire jaw and all of the teeth in one image.

Cone-beam computed technology is used to create a 3-dimensional image from a series of images. Because it relies on multiple images, the radiation exposure is higher than that of commonly used x-rays and is used for surgical treatments. 


Are Dental X-rays Safe?


Because dental x-rays expose us to radiation, patients sometimes wonder if they are safe. Routinely we are exposed to radiation from a number of sources, even sunshine, air and soil around us. 

To help limit the amount of radiation exposure to your thyroid gland when taking x-rays, your dentist may cover your throat with a special collar.
