I recently had a virus, probably close to walking pneumonia, and am still not quite myself. The last few days my teeth have been kind of sensitive and i feel like I have slight nasal drainage in my throat, could that be caused by the virus, or do I need to see a dentist? I don't feel sick really, my mouth just feels uncomfortable. And normally i drink hot tea at night with milk and sugar, but it hasn't tasted good to me.
