• Quick Summary:

•  Facial swelling from a tooth almost always means an infection has spread past the tooth itself. It's not something that settles down on its own. Waiting can let it move toward your airway or bloodstream. Same-day treatment of oral infections stops that spread.

• When your face swells, it's not the tooth causing issues. It's your body fighting something bigger. We see this weekly. A patient calls saying their cheek looks puffy, or their jawline feels tight under the skin. It's a tooth infection that's pushed past the root and into the surrounding tissue. 

• A tooth abscess starts small. If left alone, the infection follows the path of least resistance. Sometimes that's up toward the eye, sometimes it's down toward the neck. The second path is the one that worries us most.

• Swelling that's spreading, not staying in one spot

• A fever with the puffiness

• Trouble opening your mouth all the way

• Any tightness in your throat or trouble swallowing

• Swelling near your eye or under your jaw

• If you notice any of those, get it checked. If the swelling showed up fast, over a few hours instead of a few days, that means the infection is active now. We treat oral infections directly, but an exam happens first. This helps us see exactly where the infection sits and how far it's traveled.
