Can Infected Sinuses Cause Toothache?

Sinus infections can cause toothache-like pain, especially in the upper back teeth, and a calm, formal tone works very well for a dental clinic audience. Here is your content, reframed to sound professional, reassuring, and clinic-appropriate while still feeling natural.​

Picture this: blocked nose. Face pressure. Aching upper back teeth. You’re thinking, “Is it my teeth or something else?” Turns out, yes—sinus infections can mimic tooth pain, especially those upper molars. Feels just like a dental issue. That’s the overlap that trips people up. Helps to know, so you head to the right place—dentist, GP, or both.

Here at Bridge Dental and Cosmetic Studio in Isleworth, folks walk in worried about toothache. Turns out, it’s sinusitis, not decay or a crack. Like patient Sarah last month—came in tense, cheeks heavy, teeth throbbing on one side. We checked, no dental damage. Sinus cleared up, pain gone. She slept like a baby that night. Spotting it early cuts anxiety. Skips unnecessary drills. Best part, really.

Why do Infected Sinuses Cause a Toothache?

Sinuses—those air pockets in your face bones, right by upper tooth roots. Inflame with mucus. Boom, pressure builds. Irritates nerves shared with teeth. Dull ache spreads across a few molars. Not one sharp spot.

Bends forward? Worse. Head tilts quick? Ouch. Lying flat? Pressure shifts. Add nasal stuffiness, runny nose—points straight to sinuses, not teeth. Several teeth hurting at once. That’s your clue.

A classic sinus toothache day

Wake up. Cheeks heavy. Eyes fuzzy. Nose clogged. Upper back teeth ache in a line, one side. Deeper than sensitivity. Bend to grab your shoes—pain spikes quick. Straighten, eases a bit.

Pop a painkiller. Notice it ties to congestion, not chewing one tooth. No zap on bite. Gums look fine in the mirror. High chance it’s sinuses referring pain. Not a cavity. Not a crack. Relief, right?

Signs it’s probably sinuses

• Ache hits several upper back teeth. Not one lone soldier.
• Worse bending, head moves, lying down. Shifts with position.
• Blocked or runny nose. Yellow-green goop sometimes. Face pressure.
• Heavy cheeks, eyes, forehead. Smell dulled.
• No sharp bite pain on one tooth. Gums calm.

Dental red flags instead? Swollen gums. One-tooth fire. Hot/cold zing. Chew agony. Night wakings. Clear difference.

Take patient Raj. Tense jaw, multi-tooth throb, sinus drip. Thought teeth failing. X-rays clean. GP meds for sinuses—two days, smiling easy. “Why didn’t I know?” he said. Stories like his? Common.

How to handle it—and when to call

Sinus driving it? Treat the source. Pain fades too. Rest. Hydrate. Saline rinses. GP picks meds. You’ll notice relief.

Most times, teeth are fine. No damage. Just resolves. But don’t ignore bad pain.

See dentist if:

• Lasts days.
• Intense, pinned to one spot.
• Swelling, breaks, bite/temp sensitivity.

FAQs on whether Infected Sinuses Cause Headaches
