Symptom Guide
Sensitive Teeth
If ice water makes you wince or you have started chewing on one side only, your teeth are asking for a smaller favor than you might fear.

What sensitivity might mean
- Exposed root surfaces. When gums recede even a millimeter or two, the root underneath has no enamel, and cold hits it directly. This is the most common culprit.
- Worn enamel. Years of hard brushing, acidic drinks, or nighttime grinding thin the armor, and the layer underneath is far chattier about temperature.
- A crack or leaking filling. Sensitivity concentrated in one tooth, especially with biting pressure, suggests a structural problem rather than a surface one.
- Early decay. A cavity that has passed through enamel often announces itself first with sweetness sensitivity before cold ever bothers it.
Self-care today
Start desensitizing toothpaste twice a day and stick with it; it needs a couple of weeks to build up. Swap to a soft brush and lighten your grip, holding it like a pencil rather than a scrub brush. Go easy on citrus, soda, and sipping acidic drinks over long stretches, and wait thirty minutes after acidic food before brushing so you are not scrubbing softened enamel.
When to call promptly
Book an exam if the sensitivity is limited to one identifiable tooth, if it lingers more than a few seconds after the trigger is gone, if heat has joined the party, or if a month of good home care has not moved the needle. Lingering or heat-triggered pain can mean the nerve is involved, and that is worth catching while options are still simple.
How we evaluate and treat it
At either Roanoke office we map exactly which teeth react and to what, check for recession, cracks, and decay, and X-ray anything suspicious. Fixes are matched to causes: fluoride varnish to strengthen thin enamel, bonding to cover an exposed root, a filling where decay has started, or a night guard when grinding is the engine behind it all. If you want whiter teeth without the zing, ask us about professional whitening paced for sensitive enamel.

Frequently Asked Questions
Does sensitivity always mean a cavity?+
No. Plenty of sensitivity comes from exposed root surfaces or worn enamel with no decay at all. The pattern matters: a brief zing from cold that fades instantly is usually exposed dentin, while pain that lingers or shows up with heat points toward the nerve and needs an exam sooner.
How long should I try desensitizing toothpaste before calling?+
Give it two to four weeks of twice-daily use on the sensitive area without rinsing it away afterward. It works by plugging the microscopic tubes in exposed dentin, and that takes repetition. If four weeks changes nothing, or the sensitivity is getting worse, book an exam.
Why did my teeth get sensitive after whitening?+
Whitening temporarily opens the pores of the enamel, and for a day or two teeth can feel zingy. That version fades on its own. If you are whitening at home and sensitivity keeps climbing, pause and talk to us about a gentler schedule or a professional option built around your enamel.
Can grinding my teeth cause sensitivity?+
Absolutely. Clenching and grinding flex the teeth at the gumline, which chips away tiny notches of enamel and exposes the softer layer underneath. If your sensitivity comes with morning jaw tightness or flattened-looking edges, grinding is a prime suspect and a night guard may fix the cause rather than the symptom.
What can the dentist do that toothpaste cannot?+
We can find the reason. Depending on what the exam shows, options include professional fluoride varnish, bonding over exposed root surfaces, a filling if decay is present, a night guard for grinders, or simply coaching on brushing pressure. Matching the fix to the cause is the whole game.
