Pulp hyperemia- when tooth sensitivity lingers.

That twinge from cold or sweets that lingers long after the trigger is gone? That's not everyday sensitivity. It's often pulp hyperemia — early irritation inside your tooth's living core, and it's worth a gentle look.

Everyday sensitivity vs. pulp hyperemia

A quick, sharp twinge that fades in seconds usually points to exposed dentin from receding gums or worn enamel. Pulp hyperemia is different — the ache lingers, one tooth may stand out, and it often follows deep decay, a recent filling or crown, a cracked tooth, grinding, or a knock. Our tooth sensitivity guide goes deeper on the difference.

Signs to watch for

• Cold or sweet pain that lingers after the trigger is gone
• One specific tooth standing out
• Sensitivity after recent dental work
• Throbbing, spontaneous pain, or pain that keeps you up at night (call promptly)

How we help

We listen to your symptoms, examine the tooth, and use gentle cold testing plus a low-dose digital X-ray to find the cause. Then we treat it — sealing decay, protecting the tooth, or adjusting the bite — and follow up to make sure it settles. Caught early, an irritated pulp often calms down and the tooth stays healthy. If the pulp can't recover, a gentle root canal can still save your natural tooth.

Waiting can let irritation progress into pulpitis, with more constant pain. Acting early keeps treatment smaller. Nervous about a visit? You're not alone — new patients are welcome and booking takes just a moment.
