Tooth Sensitivity: Why It Happens and How to Fix It

That Zing When You Sip Something Cold

If a cold drink, a hot coffee, or a spoonful of ice cream sends a sharp jolt through a tooth, you've got tooth sensitivity - one of the most common dental complaints there is. It's usually manageable once you know what's causing it, and sometimes it's a sign of something worth checking. Here's how to think about it, with help from your Ottawa dentist.

What's Actually Happening

Under your enamel is a softer layer called dentin, threaded with tiny tubes that lead to the nerve. When enamel wears thin or the gumline pulls back, those tubes get exposed - and hot, cold, sweet, or acidic things can reach the nerve and trigger that familiar zing. Sensitivity, in other words, is usually about something exposing the dentin.

Common Causes

A few things tend to be behind it: enamel worn down by acidic foods or aggressive brushing; receding gums exposing the root; a cracked or worn tooth; grinding; brushing too hard with a stiff brush; recent whitening (temporary); or a cavity or worn filling. Some causes are harmless and fade; others need attention - which is why persistent sensitivity is worth a look.

What You Can Do at Home

For mild, general sensitivity, a few steps help: switch to a desensitizing toothpaste and give it a couple of weeks to work, use a soft brush with gentle pressure, ease up on acidic foods and drinks, and don't brush right after acidic things (wait 30 minutes). These simple changes resolve a lot of everyday sensitivity.

When to See Your Dentist

Some sensitivity is a red flag. If it's sharp and focused on one tooth, lingers after the trigger is gone, or hurts when you bite down, it can point to a cavity, a crack, or an exposed root that needs treatment. A dental exam is the fastest way to tell everyday sensitivity from something that needs fixing.

In-Office Solutions

When home care isn't enough, we treat the cause. Fluoride treatments strengthen enamel and calm sensitivity, bonding can cover exposed roots, a night guard protects teeth if grinding is to blame, and gum grafting restores the gumline when recession is significant. And of course, a cavity or cracked tooth gets repaired directly.

Preventing Sensitivity

The best defence is gentle, consistent care: a soft brush, light pressure, moderation with acidic foods, and regular checkups so small problems are caught before they start to sting.
