Why are my teeth sensitive?

If you’ve ever winced when you sip a hot coffee, take a bite of ice cream or brush your teeth too briskly – you’re not alone. Tooth sensitivity is a common issue but understanding it can help you manage or eliminate the discomfort. Here’s what we at Diamond Dental Care want you to know.

What is tooth sensitivity?

Tooth sensitivity (sometimes called dentine hypersensitivity) typically presents as a short, sharp pain in response to stimuli like hot, cold, sweet or acidic foods and drinks, cold air, or even brushing. It happens when the protective layers of the tooth (enamel) are compromised and the underlying dentine becomes exposed, allowing the nerve endings to be stimulated.

What causes sensitivity?

There are several common causes:

• Enamel erosion: Acidic foods/drinks, reflux, frequent vomiting or highly acidic diets can wear away your enamel.
• Gum recession: When gums pull back, the root surface (which isn’t covered by enamel) becomes exposed and can be more sensitive.
• Toothbrush abrasion: Using a hard-bristled brush, brushing too aggressively or horizontally can wear tooth surfaces and cause sensitivity.
• Cracked or chipped teeth: These can allow external stimuli to reach the inner tooth nerves more easily.
• Gum disease or exposed roots: Disease-related damage can expose dentine.
• Recent dental treatment: Sometimes after a deep filling or professional cleaning you might experience temporary sensitivity.

What you can do at home

• Use a soft-bristled toothbrush and brush gently, ideally with a circular motion rather than side-to-side scrubbing.
• Choose a desensitising toothpaste (look for fluoride plus active ingredients like potassium nitrate) and give it time (several weeks) to take effect.
• Avoid or reduce highly acidic or sugary foods and drinks. If you do consume them, rinse with water afterwards and wait 30 minutes before brushing.
• Use a fluoride mouthwash if recommended by your dentist.
• Be mindful of grinding or clenching your teeth. This can wear down enamel and trigger sensitivity.

Treatment options at the dental practice

If home care doesn’t relieve your sensitivity, we can help with:

• Application of fluoride varnish or gels in-practice to strengthen enamel and reduce nerve response.
• Bonding or filling exposed root surfaces or defects
• In cases of underlying gum disease or recession, we can offer periodontal treatment and gum-recession management.
• Advice and treatment for grinding/clenching (for example, a night guard) if this is contributing.
• If the cause is deeper (e.g., tooth fracture, internal damage) we may need to do further investigation to find and then treat the root cause rather than just the symptom of sensitivity.

When to get tooth sensitivity checked

If you experience:

• Persistent or worsening sensitivity over weeks despite trying our home care tips
• Sensitivity following an accident or trauma to your mouth or a cracked/chipped tooth
• Sensitivity accompanied by other symptoms (swelling, pain even at rest, darkening of a tooth)

… then you should book an appointment. We’ll assess your mouth carefully to determine the root cause of your sensitivity and devise an appropriate treatment plan.
