The aim of this study was to report the presentation of oral lesions found in a post-COVID-19 patient. A 78-year-old female patient fifteen days post-COVID-19, confirmed through the PCR test, had pain in the mouth with a Visual Analogue Scale (VAS) 8, dysgeusia and odynophagia. Erosive lesions were observed with circumscribed halos, of different sizes along the entire length of the dorsum, bilateral margins of the tongue and labial mucosa. Topical use of vitamin E 40 mg, nystatin oral suspension 100000UI and artificial saliva spray was prescribed. After 14 days, complete repair was observed. However, the patient worsened her respiratory failure and died after 2 days. There is still insufficient evidence to confirm whether this patient’s oral lesion is the result of a direct viral infection with SARS-CoV-2. The relevance of inserting the dentist in the care team for infected patients stands out and we encourage the performance of intraoral evaluation, even after medical discharge. In this way, it will be possible to understand its long-term oral manifestations of COVID-19.

KEY WORDS: COVID-19, SARS-CoV-2, oral lesions, immunosuppression, intensive care unit.
