Sensitive Teeth in Amstelveen: Causes, Triggers, and Treatments That Actually Help

That sharp, fleeting pain when cold water hits a tooth, or the dull ache after biting into something sweet — if this sounds familiar, you're not imagining it. Dental sensitivity affects around one in eight adults and is one of the most common complaints we hear at Dentinn in Amstelveen. The good news is that in most cases it's very treatable, once you understand what's actually causing it.

What Makes Teeth Sensitive?

Your teeth have a hard outer layer of enamel covering the dentine beneath. Dentine is full of microscopic channels — dentinal tubules — that run straight to the nerve at the tooth's centre. When enamel wears thin (through erosion or abrasion) or when the gum recedes and exposes the root surface, these channels open up to the outside. Cold, heat, sweet or acidic stimuli travel down the tubules and fire off a nerve response. That's the zing you feel.

It's worth noting this is different from a toothache, which tends to linger. Sensitivity is typically brief — seconds, not minutes.

Common Triggers (and a Few Surprising Ones)

• Cold food or drink: ice water, ice cream, cold air on an exposed tooth are the most classic triggers
• Sweet or acidic foods: citrus, vinegar dressings, fizzy drinks lower the mouth's pH and activate exposed tubules
• Hot drinks: less common, but severe enamel wear can make hot coffee painful too
• Whitening products: both over-the-counter strips and professional whitening can cause temporary sensitivity in some patients — it usually resolves within a few days
• Hard brushing: aggressive brushing wears down enamel at the gum line and causes gum recession over time
• A specific tooth that reacts under biting pressure: this often signals a crack or a leaking dental filling rather than general sensitivity

How We Figure Out What's Going On

Because sensitivity can mimic pain from other causes — a cavity, an abscess, a cracked tooth — a proper dental check-up matters before you start any treatment. At Dentinn, we check how many teeth are affected (generalised erosion looks different from a single cracked tooth), measure gum recession levels, and take X-rays when needed. If you're wondering what that appointment actually involves, our guide on what happens at a dental check-up walks you through it step by step.

It's also worth checking whether enamel erosion is a contributing factor — sensitivity and erosion often go hand in hand.

Treatments That Actually Help

• Desensitising toothpaste: products with potassium nitrate or stannous fluoride gradually block the dentinal tubules. Results build over two to four weeks. Use it last thing at night and don't rinse after — that thin film on your teeth is doing the work
• Fluoride varnish: applied in the chair by our dental hygiene team, this forms a more durable barrier over exposed dentine than toothpaste alone. It's quick, painless, and effective for months
• Bonding or glass ionomer: for sensitivity at a specific spot on the root surface, we apply a thin protective layer directly over the exposed area
• Addressing gum recession: when recession is the root cause, treating the gum problem gives a better long-term result than just managing symptoms
• Root canal: reserved for situations where the nerve itself is irreversibly inflamed — a root canal removes the nerve and ends the sensitivity permanently, but this is a last resort

What Doesn't Actually Help

Switching to a soft-bristle brush is sensible — but brushing less thoroughly because it hurts is the worst thing you can do. Plaque build-up accelerates enamel and gum problems, making sensitivity worse. And avoiding the dentist because you're worried about discomfort during the visit is a pattern we see a lot. In practice, a check-up at Dentinn is not painful, and identifying the cause early keeps treatment simple. Sensitivity that you ignore for a year tends to become a more complicated problem.
