Toothache and tooth sensitivity are two of the most common complaints we hear at Hermitage Dental Practice — and for good reason. That sudden twinge when you sip a cold drink or a dull ache that lingers in your jaw can be more than just uncomfortable — it could be a sign that something deeper is going on with your oral health.

What Causes Tooth Sensitivity?

Tooth sensitivity usually occurs when the protective layer of enamel wears down or when gum recession exposes the sensitive dentine underneath. This can make your teeth more reactive to:

Hot or cold food and drinks
Sweet or acidic items
Even cold air or brushing

Common causes include:

Enamel erosion from acidic foods or brushing too hard
Gum disease that causes gum recession and exposes tooth roots
Tooth grinding (bruxism)
Cracked or chipped teeth
Worn fillings or cavities

What About Toothache?

A toothache can range from a mild irritation to severe pain — and it’s always a sign that something needs attention. It might be caused by:

Tooth decay or cavities
Infection or abscess
Gum disease
A damaged or fractured tooth
Impacted wisdom teeth

Unlike sensitivity, which may be triggered by temperature or pressure, a toothache often signals an issue that may require prompt treatment.

When to See a Dentist

If you experience persistent tooth pain or ongoing sensitivity that doesn’t improve with over-the-counter products, don’t ignore it. These symptoms may be early warning signs of bigger issues — and early treatment is always the best approach.

At Hermitage Dental Practice, we’ll get to the root of the problem and recommend the best course of action, whether that’s a simple filling, desensitising treatment, or a more comprehensive approach.
