SARS-CoV-2—the virus that causes the novel pneumonia named coronavirus disease 19 (COVID-19)—resulted in the closing of most dental offices throughout the world to all treatment other than emergent care.1 As dental practitioners begin to resume normal elective care, one challenge has been trying to convince dental staff and patients that treatment is safe and professional oral care is necessary.2

A recent survey showed that 71% of dental patients had concerns about going to the dental office during the COVID-19 pandemic due to fear of transmission.3 Many of these COVID-19 fears continue to prevent patients from seeking medical and dental care, even though offices have now reopened for elective care.4

The increase in periodontal tissue destruction arising from delayed professional care has been well documented in the literature.5 This article will briefly examine three aspects of periodontal disease as it relates to COVID-19 so clinicians can have a better understanding when explaining the importance of periodontal therapy to patients.

Stress-related factors

The COVID-19 pandemic has caused a tremendous amount of stress for the average individual, both financially and psychologically. In one survey, 70% of respondents stated that the months during this pandemic have been the most stressful time in their entire lives.6 Many studies have demonstrated a correlation between stress and an increased risk of developing periodontal disease and clinical attachment loss.7 Both financial stresses and psychological stresses have been shown to double and even quadruple the risk of developing periodontal attachment loss.8

In addition, those under chronic stress have been found to possess increased levels of cortisol in their salivary fluids. The release of chronic cortisol leads to a decreased immunity and upregulation of various inflammatory markers. The result of chronic inflammation and decreased immune function can lead to gingival inflammation and the destruction of periodontal tissue.9 Further, periodontal abscess and bleeding can often occur under these circumstances (figure 1). Periodontal therapy can play a major role in treating and avoiding tissue breakdown.

Behavioral effects

Coping mechanisms to deal with anxiety, stress, and depression can often involve poor diet, bodily neglect, and deleterious habits such as alcohol, smoking, and drug consumption.10 In addition, lack of hygiene and professional cleanings from neglect/forced neglect can lead to gingival tissue destruction. One study showed that bacteria recolonized teeth six to eight weeks after professional
scaling and root planing.11

Many offices have been closed for months and continue to avoid hygiene procedures because of concerns about viral transmission. Periodontal destruction has been shown to increase in a dose-dependent function with smoking use.12 Poor dietary trends have also been shown to increase inflammation and oral disease.13 Many patients whose oral health was controlled under strict periodontal care prior to the pandemic can experience relapse when changes in social history occur (figures 2 and 3). It is imperative that oral hygiene and periodontal care be reinstituted to prevent continued breakdown.

Financial concerns

As we emerge from the post–COVID-19 fallout, many financial reports have drawn possible similarities to the financial crisis of 2008. When analyzing the repercussions of the 2008 financial crisis
in dentistry, spending trends suggest that it took more than a year before the economic downturn affected the dental care industry. This slowdown resulted in lower case acceptance rates, fewer office visits, and reduced availability of third-party financing. Dental gross production decreased considerably, especially large case treatment plans. Restorative procedures dropped 5%, while periodontal and hygiene procedures actually increased 8%.14 Patients spent more money on valued conservative treatment and less on cosmetic procedures.

Regeneration of periodontally compromised teeth is a valued treatment that is both conservative and may increase case acceptance compared to dental implant therapy. With the ability to “save” compromised teeth, more costly procedures such as extraction, grafting, and implant therapy can be avoided. If the 2008 economy is any indication of what the 2020 economy may entail, periodontal therapy is going to play an extremely important role in dental treatment.
