COVID-19 manifests a wide range of symptoms, from fever and dry cough to severe pneumonia progressing to adult respiratory distress syndrome. Creactive protein (CRP) is known as a marker of hyperinflation. Patients with high levels of CRP have worse prognoses with COVID-19. Recent studies have shown the association between oral health status and systemic diseases and the impact of good oral care on risk reduction of viral respiratory diseases.  Objectives of the Study To find the impact of oral hygiene condition on the severity, duration of hospitalization, and CRP values of post-Covid-19 recovered patients of Raichur.  Methodology The study design was a cross-sectional, questionnaire survey. Convenient sampling was used.105 patients were included from Navodaya Medical College and Hospital (NMCH) from April 2021 to August 2021. An open-ended, pretested questionnaire was used which was divided into two sections. First section for oral health evaluation and second section for COVID-19 severity. This was done via telephonic interviews. The HRCT chest report and C-Reactive protein reports were collected from medical records department of NMCH Included patients above 18 years old, both genders with positive RT- PCR report. Excluded patients with medical complications and who failed to complete the questionnaire or refuses to provide consent.  Result Inverse co-relation between the oral health status and the Covid-19 severity, duration of hospital stays and the CRP values were found using the ANOVA and Pearson correlation coefficient and was found statistically significant.  Conclusion This study found patients with poor oral health status had longer duration of hospital stay, increased Covid-19 severity and the CRP values.
