Is it common to have painful teeth and gums from the flu?
If you are having sinus congestion your upper teeth may hurt because the roots of your teeth, especially your molar teeth, are close to the sinus area. Taking a decongestant may help and the teeth should feel better when the pressure is gone and the cold is over. Can’t explain why the gums would hurt as well. Just keep brushing and flossing to prevent gingivitis. Gingivitis, inflammation of the gums, doesn’t normally hurt, but gums can become swollen and bleed.
