MIT researchers say these are the unsafe businesses to avoid during COVID-19 and Dentists are okay

Want to know which businesses are safe to frequent during the coronavirus pandemic? Data crunchers at MIT analyzed 26 categories of businesses by a dozen metrics for necessity and crowdedness and determined which are most essential and safest, and vice versa. The insightful research aims to guide policymakers in choosing which commerce to reopen, and, as cases rise, which to close first or regulate.

The study, in the Proceedings of the National Academy of Science, identifies the businesses that have the best overall risk-benefit profiles when weighing important factors such as essential value to shoppers and the economy, as well as relative risk of contracting COVID-19—or as one researcher put it, which businesses give us the most bang for our buck. At the top of the pile are banks, which are economically important yet uncrowded and visited infrequently and for short periods of time.


(Probably worth the risk)

  • Banks
  • Dentists
  • Colleges and universities


(Definitely not worth the risk)

  • Gyms
  • Cafes, juice bars, and dessert parlors (3rd highest risk of 26 categories)
  • Sporting goods stores
  • Liquor and tobacco stores


(Higher risk but also sometimes perceived as essential)

  • Grocery, general merchandise, electronics, clothes, and shoe stores
  • Fast food and sit-down restaurants (highest risk of 26 categories)
  • Auto dealers and repair
  • Places of worship


(Mid-level risk vs. benefits)

  • Salons and barbers
  • Hardware, furniture, office supply, and department stores


(Low risk, but also nonessential or available online)

  • Bookstores (order local online!)
  • Amusement parks
  • Movie theaters (which, the researchers note, are often mostly empty off-peak times)
  • Office supply stores
  • Casinos
  • Museums

Current business restrictions do not follow these guidelines. For example, the researchers note that tobacco and liquor stores have experienced only 5% declines in attendance, yet are more risky (small, busy stores). Meanwhile, colleges are a good trade-off.

“They tend to be places with big campuses. When people are worried about colleges and universities, they’re mostly worried about dormitories and parties, people getting infected that way, and that’s fair enough. But [for] research and teaching, these are big spaces, with pretty modest groups of people that produce a lot of economic and social value,” said coauthor and economics postdoctoral student Seth Benzell, who is a career academic.

Coronavirus Update

As the COVID-19/Coronovirus impacts our community, we are limiting our office hours.

The AMERICAN DENTAL ASSOCIATION, along with recommendations from our Gov. Ducey, has announced that dentists across America and here in Arizona, should not render any elective procedures. This includes dental  cleanings, fillings/restorations, crowns.

Keeping with these recommendations, we have cancelled all patients’ appointments for elective procedures until April 30.  We are well aware that some of you may experience an urgent dental need and for that reason, we are available to you on a pre-arranged basis.  Even if you are not a patient of record, we will see you.  In an effort to limit community exposure, we would rather see you in our office, than for you to go to the Emergency Room at one of the local hospitals when you have a dental emergency.   We have at our disposal a community of dental specialists that can handle all types of dental emergencies.  We are the first responders for triaging our patients.  Therefore, if you are experiencing DENTAL PAIN, FACIAL TRAUMA, BROKEN TOOTH/TEETH, TOOTH PAIN, GUM PAIN, and whereby delaying treatment would result in additional harm, please do not go to the hospital emergency room, CONTACT US!
