Tooth Sensitivity Treatment in Leicester
That sharp, sudden twinge when you sip a hot coffee, bite into ice cream or breathe in cold air — tooth sensitivity is one of the most common complaints we see, and one of the most misunderstood. Many people simply put up with it, assuming it's just "one of those things." But sensitivity is your teeth sending a signal, and that signal usually has a treatable cause. This page explains what's really happening when your teeth feel sensitive, what's behind it, and the practical steps — at home and in the chair — that can bring you lasting relief.
What Is Tooth Sensitivity?
β
To understand sensitivity, it helps to picture the layers of a tooth. The hard outer enamel protects the crown, and the roots are covered by a softer layer called cementum. Beneath both sits dentine, which is riddled with thousands of microscopic tubes leading straight to the nerve at the centre of the tooth. When enamel wears thin or the gum recedes and exposes the root, those tiny tubes are left open — so hot, cold, sweet or acidic stimuli travel down them and reach the nerve directly. It's a bit like the difference between touching a wire that's insulated and one that's bare: the same signal suddenly feels much sharper. That brief, shooting sensation is the hallmark of sensitive teeth.
Common Symptoms of Sensitive Teeth
β
Sensitivity tends to show up as a short, sharp pain in response to a trigger, rather than a constant ache. You might feel it with cold drinks or ice, hot tea or coffee, sweet or sour foods, or even a rush of cold air on a winter's day. Brushing or flossing can set it off too. For some people it's an occasional nuisance; for others it's enough to change how they eat and drink. One important distinction: sensitivity is usually fleeting and tied to a trigger, whereas a lingering, throbbing or spontaneous ache can point to something more serious like decay or infection — and that's worth having checked promptly.
What Causes Tooth Sensitivity?
β
Sensitivity almost always comes down to enamel being worn away or roots being exposed. Understanding which applies to you is the key to treating it, rather than just masking it.
β
Enamel Wear from Brushing Too Hardβ
β
It sounds counterintuitive, but scrubbing hard with a stiff brush is one of the most common causes. Aggressive brushing gradually wears away enamel and pushes gums back, exposing sensitive surfaces. Gentle, thorough brushing with a soft-bristled brush protects far more than it misses.
β
Acid Erosion from Food and Drink
β
Fizzy drinks, fruit juices, wine and citrus are all acidic, and frequent exposure softens and dissolves enamel over time. Acid reflux and some medical conditions can have the same effect from the inside. Once enamel is lost this way, the dentine beneath is left exposed.
β
Gum Recession
β
When gums shrink back — through age, gum disease , or over-vigorous brushing — the root surfaces they once covered become exposed. Roots have no enamel to protect them, so they're far more prone to sensitivity than the crown of the tooth.
β
Teeth Grinding and Clenching
β
Grinding (bruxism) , often during sleep, puts enormous force on your teeth and slowly wears down enamel. Many people don't realise they do it until a partner mentions the noise or we spot the tell-tale wear patterns during a check-up.
β
Dental Causes: Decay, Cracks and Worn Fillings
β
Sometimes sensitivity is a symptom of a specific problem — a cavity, a hairline crack , a leaking or worn filling, or gum disease. These won't settle with a special toothpaste; they need diagnosing and treating at the source, which is exactly why a persistent or worsening sensitivity is worth a professional look.
β
How to Manage and Treat Sensitive Teeth
β
The good news is that sensitivity is highly treatable once we know the cause. At home, a desensitising toothpaste used consistently can help block those microscopic tubes over a few weeks, and switching to a soft brush with a gentle technique protects your enamel and gums. Cutting back on acidic food and drink — and waiting a while before brushing after them — gives enamel a chance to recover. In the practice, we can offer stronger solutions: fluoride varnishes that strengthen enamel, bonding or sealants to cover exposed root surfaces, treatment for any underlying gum disease or decay, and a custom night guard if grinding is the culprit. Because the right treatment depends entirely on the cause, the most useful first step is nearly always a proper assessment.
β
Why It's Worth Getting Checked
β
Reaching for sensitivity toothpaste is sensible, but if it isn't helping, that's a clue the cause needs addressing directly rather than masking. Sensitivity can also be an early warning of decay, a crack or gum disease — problems that are far easier and cheaper to treat when caught early. A quick assessment turns guesswork into a clear plan.
