#5 Swollen gums

If a tooth is aching, there is a chance the gums are swollen as well. The swelling might not be there all the time. Also, it might not be painful when you touch it, or you might feel a sharp pain even with a slight touch.

Furthermore, most of the time, swelling happens when there are acidic products of dead tissues. This sometimes leads to edema (swelling) outside your root.

Moreover, you might get small pimples on the gums. These are called an abscess, parulis, or gum boil. Also, the pimple might discharge fluid from the infections inside your teeth.
