An abscessed tooth is an example of an oral emergency. It can cause severe pain and lead to serious complications. These infections can be very time-sensitive, and if they aren't treated promptly, could prove to be life-threatening. These can be life-threatening emergencies so don't take them lightly. You can check if there is an infection in your oral cavity or abscessed tooth by using a magnifying glass, a penlight, and a small or compact mirror. You should look for anything that looks like an infection or a red, swollen bump. Your oral health is at risk from serious infections. These infections travel from the root of the teeth to the soft tissues in your mouth and into your bloodstream. You should immediately contact us if you think you might have an infection.
