Tooth Sensitivity FAQs: Cold, Sweet, and Lingering Pain Answered

Common questions we hear about tooth sensitivity — from why cold hurts to when a twinge means something more serious.
Sensitivity questions come up in almost every check-up. Here are the ones we hear most often in our South Surrey chair.
Why does cold water hurt one specific tooth?
A single tooth reacting more than the others usually points to something localised — a small crack, a leaky filling, deep decay, or early pulp irritation. It's worth getting checked rather than waiting.
Is it normal for a new filling or crown to be sensitive?
Mild cold sensitivity for a week or two after dental work is common and usually settles. If it lingers beyond that, gets worse, or wakes you at night, let us know — the bite may need a small adjustment.
What's the difference between sensitivity and a cavity?
Everyday sensitivity is a quick twinge that fades in seconds and often affects several teeth. A cavity or pulp problem tends to focus on one tooth and lingers after the trigger is gone.
Do sensitivity toothpastes actually work?
Yes, for dentin-related sensitivity — but they take two to four weeks of consistent use. They won't fix a crack, decay, or an inflamed pulp.
When should I book an appointment?
If pain lingers more than a few seconds, throbs on its own, or one tooth clearly stands out. Our tooth sensitivity guide covers more, and new patient booking is quick.
