Should I Brush My Teeth Before A Pcr Test
PCR (Polymerase Chain Reaction) test is a commonly used test to detect the presence of COVID-19 virus in the body. It is a highly sensitive test and requires a small sample of saliva or mucus from the nose. However, many people are confused about whether they should brush their teeth before a PCR test or not. In this article, we will discuss the importance of brushing teeth before a PCR test and whether it affects the test results or not.
Why Do People Brush Their Teeth Before A PCR Test?
Many people believe that brushing teeth before a PCR test is important to avoid false positive results. They think that if there are any virus particles in their mouth, brushing teeth can eliminate them, and the test will not detect them. Moreover, some people also think that brushing teeth can help to reduce the risk of getting infected with COVID-19.
Does Brushing Teeth Affect PCR Test Results?
According to medical experts, brushing teeth before a PCR test does not affect the test results. It is because the PCR test detects the virus particles in the respiratory tract, not in the mouth. Therefore, even if there are virus particles in the mouth, brushing teeth will not affect the test results. Moreover, brushing teeth does not reduce the risk of getting infected with COVID-19 as the virus spreads through respiratory droplets, not through saliva or mucus.
What Should You Do Before A PCR Test?
Before a PCR test, you should follow the guidelines provided by your healthcare provider. Generally, you should avoid eating, drinking, smoking, or chewing gum for at least 30 minutes before the test. Moreover, you should not use mouthwash or any other oral hygiene product before the test as it may interfere with the test results. If you have any doubts or concerns, you should consult your healthcare provider.
Conclusion
In conclusion, brushing teeth before a PCR test does not affect the test results. It is a myth that brushing teeth can help to avoid false positive results or reduce the risk of getting infected with COVID-19. Therefore, you should follow the guidelines provided by your healthcare provider before a PCR test and avoid using any oral hygiene products that may interfere with the test results.
