Sensitive Teeth in Epsom:
Causes, Relief & Treatment
A sharp twinge with cold drinks, ice cream, or even a deep breath of cold air? Tooth sensitivity isn't something you have to live with — and once we know the cause, it's almost always treatable.
Sharp pain on biting, or pain that lingers after the trigger goes away? That's not normal sensitivity — it can signal a crack or nerve issue. Call us for a same-day appointment: 01372 679192.
Sensitivity Is a Symptom — Not a Diagnosis
Tooth sensitivity (sometimes called dentine hypersensitivity) affects around one in three UK adults. It happens when the protective enamel on your teeth is worn down, or the gums recede and expose the softer root surface — leaving microscopic channels that lead straight to the nerve inside your tooth.
The important thing to understand: sensitivity is a signal, not a condition in itself. It can come from worn enamel, receding gums, decay, a cracked tooth, a failing filling, or aggressive brushing. Until we identify why your teeth are sensitive, no toothpaste is going to fix it long-term.

Where Tooth Sensitivity Comes From
There are four common sources of sensitivity. The right treatment depends entirely on which one you have — which is why a proper diagnosis matters.
Worn or Eroded Enamel
Acidic food and drink, aggressive brushing, or grinding can wear away the enamel, exposing the dentine layer underneath. Dentine contains tiny tubules that lead directly to the nerve — so cold, hot, and sweet stimuli travel straight in. Often improvable with fluoride, sensitive toothpaste, and habit changes.
Receding Gums
When gums recede, they expose the root surface — which has no enamel covering. Roots are far more sensitive than the crown of a tooth. Recession is often caused by gum disease or hard brushing. Treatment can include desensitising agents, bonding to cover the root, or treating the underlying gum issue.
A Cracked Tooth or Failing Filling
If sensitivity is isolated to one tooth — especially a sharp pain on biting — the cause is often a hairline crack or a filling that's leaking. This can't be fixed by toothpaste. We'll find the affected tooth and repair it before the crack reaches the nerve.
Decay or Nerve Involvement
Hidden tooth decay can cause sensitivity long before you can see a hole. If the pain lingers for more than a few seconds after the trigger, or wakes you at night, the nerve may already be involved — and the tooth needs treatment soon to avoid root canal or extraction.
Pain that lingers, throbs, or wakes you at night? This is a warning sign that decay or infection has reached the nerve. Read our guide to toothache in Epsom or call us directly — the sooner we see you, the more options you have.
What Sensitive Teeth Actually Feel Like
If any of these sound familiar, it's worth getting checked — what feels like normal sensitivity often has a treatable cause underneath:
- A sharp twinge with cold drinks or ice cream — the most classic sign of exposed dentine or worn enamel
- Pain when eating something sweet — sugar can travel through the dentine tubules and trigger the nerve
- Discomfort with hot drinks — often a more concerning sign than cold sensitivity, may suggest nerve involvement
- Pain when breathing in cold air — common in winter or after exercise outdoors
- Sensitivity in one specific tooth when brushing — often points to recession, a crack, or decay in that area
- A sharp jolt when biting down — different from temperature sensitivity, this often signals a cracked tooth
- Pain that lingers for 30+ seconds after the trigger — a warning sign that the nerve may be inflamed and needs urgent assessment
- Sensitivity around the gum line — usually points to gum recession or aggressive brushing
- Sensitivity that started after whitening or a recent filling — often temporary, but worth checking if it doesn't settle in 2–3 weeks
Stop reaching for sensitive toothpaste alone. It can mask the symptom but won't fix the cause. A proper exam tells you exactly what's going on. New patients: 50% off this spring.
What's Actually Causing It
Sensitivity rarely has a single cause — usually two or three of these are working together. Identifying yours is the first step to lasting relief.
Brushing Too Hard
One of the most common causes we see. Aggressive brushing — especially with a hard-bristled brush — wears down enamel and pushes gums to recede. Switch to a soft brush and let it do the work, particularly with electric toothbrushes.
Acidic Diet
Fizzy drinks, fruit juice, sparkling water, wine, kombucha and citrus all soften enamel. Sipping these throughout the day keeps your teeth in an acidic state — far worse than drinking them in one go with a meal.
Gum Recession
Caused by gum disease, hard brushing, age, or genetics. Once gums pull back, the unprotected root surface is exposed — and it's much more sensitive than the crown. Often gradual, so people don't notice until sensitivity sets in.
Teeth Grinding (Bruxism)
Grinding or clenching — usually at night — wears the enamel flat and creates microscopic cracks. Often the first thing patients notice is sensitivity. A custom night guard prevents the damage from progressing.
Decay or a Cracked Tooth
Hidden decay or a hairline crack creates a direct route to the nerve. If sensitivity is sudden, sharp, and isolated to one tooth — especially when biting — this is often the cause and needs prompt repair.
Recent Whitening or Treatment
Sensitivity after professional or at-home whitening is common but should settle within days to a couple of weeks. Sensitivity after a filling usually settles too — if it doesn't, the bite may need adjusting or the filling rechecked.
How We Treat Sensitive Teeth at Epsom Smiles
Treatment depends entirely on what's causing your sensitivity. We start by finding the root cause, then choose the least invasive option that gives you lasting relief — and we'll always explain why.
- Desensitising toothpaste — used correctly. Brands like Sensodyne or Colgate Pro-Relief work by blocking the dentine tubules, but only if used consistently and correctly: rub a small amount directly onto the sensitive area at night, and don't rinse. Most people use it like normal toothpaste and wonder why it doesn't work.
- Professional fluoride varnish. A high-strength fluoride coating applied in the practice strengthens enamel and reduces sensitivity quickly. Quick, painless, and often gives noticeable relief within days. May be repeated every few months for ongoing cases.
- Bonding or composite to cover exposed dentine. Where enamel is heavily worn or roots are exposed, we can bond a thin layer of tooth-coloured composite over the sensitive area to seal it off. Long-lasting and tooth-coloured.
- Treating the underlying cause. If gum disease has caused recession, we treat the gums. If grinding is the cause, we make a custom night guard. If a cracked tooth or decay is the source, we restore the tooth directly. Toothpaste alone won't solve any of these.
- Filling or crown for cracked teeth and decay. When sensitivity is caused by decay or a fractured tooth, we remove the damaged area and restore the tooth with a tooth-coloured filling, inlay, onlay or crown depending on the size.
- Root canal — only when the nerve is involved. If sensitivity has progressed to constant pain, the nerve may be irreversibly damaged. Modern root canal treatment saves the tooth and is no more uncomfortable than a filling.

Sensitive Teeth FAQs
Sudden sensitivity usually means something has changed — worn enamel, gum recession, a new cavity, a cracked tooth, a recently fractured filling, or recent whitening. If it's just a couple of days after whitening or a filling, give it 1–2 weeks to settle. If it appears out of nowhere and doesn't go away, book a check-up so we can find the cause.
Yes, but only if used correctly and only for the right cause. Sensitive toothpaste works by blocking the tubules in the dentine, so it has to sit on the sensitive area to work. Most people brush with it briefly and rinse it away. Try rubbing a pea-sized amount directly onto the sensitive area at night and don't rinse. If there's no improvement in 2–4 weeks, the cause likely isn't simple enamel wear and you need a proper diagnosis.
In most cases, yes — but the treatment depends on the cause. Worn enamel and exposed dentine can be sealed with bonding or fluoride. Recession-related sensitivity can be improved by treating the gums and using desensitising agents. A cracked tooth or decay needs the tooth itself repaired. The key is identifying which one applies to you.
Whitening (professional or at-home) can temporarily increase sensitivity because the bleaching agent passes through the enamel. It's common and usually settles within days to two weeks. Use a sensitive toothpaste during and after the whitening course, take breaks if it's intense, and avoid very cold or hot drinks for a few days. If sensitivity hasn't settled after two weeks, get it checked.
Yes — especially if it's persistent, isolated to one tooth, painful on biting, or lingering for more than 30 seconds after the trigger. These signs can mean decay, a cracked tooth, or nerve damage that won't get better on its own. Even mild sensitivity is worth investigating because it usually means the enamel or gums need attention.
Sometimes. Most sensitivity is from worn enamel or gum recession and isn't dangerous, but it can also signal hidden tooth decay, a cracked tooth, gum disease, or in some cases nerve damage. The warning signs are pain that lingers, pain that wakes you at night, throbbing, or sensitivity isolated to one tooth — these need a same-day or urgent appointment.
No — gum recession doesn't reverse on its own. The good news is it can usually be stopped, and the sensitivity it causes can be treated with bonding, desensitising agents or, in some cases, gum surgery to cover exposed roots. Most importantly, addressing the cause (gum disease, hard brushing, grinding) prevents it from getting worse.
A soft-bristled brush — manual or electric. Electric brushes with a pressure sensor are particularly good because they stop you brushing too hard, which is one of the biggest causes of sensitivity. Avoid medium or hard brushes, and avoid scrubbing back-and-forth. We'll show you exactly how to brush at your check-up.
