Tooth infection with cheek swelling urgency and treatment
A tooth infection with cheek swelling can mean bacteria have spread from the pulp or root into surrounding tissues and needs prompt dental assessment.
How urgent is a tooth infection with cheek swelling?
A tooth infection with cheek swelling can mean bacteria have spread from the pulp or root into surrounding tissues and needs prompt dental assessment.
How can an infected tooth cause cheek swelling?
Decay, a crack, or injury can allow bacteria into pulp tissue, then through the root tip into bone and soft tissue, forming an abscess.
What should you do about swelling from an infection?
Do not squeeze or puncture the swelling. Seek same-day dental assessment for examination, imaging, drainage when indicated, and treatment of the tooth.
When does cheek swelling require emergency help?
Get emergency medical help if swelling affects breathing or swallowing, spreads toward the eye or neck, or comes with marked illness.
Which treatment may be needed for the infection?
Ask whether the infection is in the pulp, around the root, or in the gum, and whether drainage, root canal treatment, or extraction is needed.
