Sensitive Teeth in Greenbank – Causes, Relief, and When to See a Dentist

Tooth sensitivity can turn everyday moments — like sipping a cold drink — into painful experiences. Learn what causes sensitive teeth and how our Greenbank dentists can help bring lasting relief.

Do you feel a sharp sting when sipping cold water, enjoying ice cream, or even brushing your teeth? You’re not alone. Tooth sensitivity is one of the most common dental concerns, and while it can be frustrating, it’s also a signal worth paying attention to. At Greenbank Family Dental, we see many local patients experiencing sensitive teeth — and the good news is, there are effective solutions.

What Are Sensitive Teeth?

Tooth sensitivity happens when the protective layer of your teeth (enamel) wears down or when gums recede, exposing the softer dentine underneath. This dentine has tiny channels that connect to the nerve inside the tooth, which is why hot, cold, sweet, or acidic foods can trigger a sudden jolt of pain.

For some, the sensitivity is mild and temporary. For others, it lingers and can make everyday eating or drinking uncomfortable.

Common Causes of Tooth Sensitivity

There isn’t just one reason your teeth might feel sensitive — often, it’s a combination of lifestyle factors and oral health conditions. Some of the most common causes include:

• Brushing too hard – using a hard-bristled brush or scrubbing can wear away enamel.

• Gum recession – often linked with gum disease, exposing the root surface.

• Dental decay or cavities – weakened or damaged tooth surfaces make nerves more vulnerable.

• Worn or cracked fillings – old restorations can break down, leaving teeth exposed.

• Grinding or clenching – this habit slowly wears enamel away.

• Recent dental work or whitening – some treatments temporarily increase sensitivity.

• Cracked or chipped teeth – tiny fractures can open pathways to the nerve.

At-Home Tips for Sensitive Teeth

If you’ve just noticed mild sensitivity, there are steps you can take at home to ease discomfort:

💬 Hygienist’s Tip from Anne

“Hard bristled toothbrushes should be banned for the damage they can do to your teeth.” – Anne, Greenbank Family Dental

🪥 For the gentlest clean, always choose a soft-bristled brush. It protects enamel and gums while still removing plaque effectively.

Other helpful home care measures include:

• Use desensitising toothpaste – these block pain signals from reaching the nerve.

• Avoid acidic drinks such as soft drinks, fruit juices, and sports drinks.

• Rinse with fluoride mouthwash to help strengthen enamel.

• Avoid extreme hot or cold foods until the sensitivity improves.

While these measures can help, they won’t fix the underlying cause if there’s decay, gum disease, or a cracked tooth.

When to See a Dentist for Sensitive Teeth in Greenbank

Mild, short-lived sensitivity isn’t always a sign of a serious problem. But if your discomfort:

• Lasts more than a few days,

• Is severe or linked to a single tooth,

• Comes with swelling, bleeding gums, or sharp pain,

• Interferes with daily eating and drinking,

…it’s time to book an appointment.

At Greenbank Family Dental, we can assess what’s really behind the sensitivity and recommend the right solution. Because sensitivity is often a symptom, not the problem itself, early attention is the best way to prevent bigger issues down the track.

Treatments for Sensitive Teeth at the Dentist

Depending on the cause, treatment for sensitivity may include:

• Professional fluoride varnish or gel to strengthen enamel and reduce sensitivity.

• Tooth-coloured fillings or bonding to cover exposed dentine or repair small cavities.

• Replacement of worn fillings that may be causing exposure.

• Gum treatment or grafting if gum recession is severe.

• Custom-made nightguards to protect against enamel wear from grinding.

• Whitening options for sensitive patients – gentle formulas that reduce risk of discomfort.

Each solution is tailored to the individual — our goal is always to protect your teeth, ease your pain, and keep you smiling confidently.

Preventing Tooth Sensitivity

The best way to avoid sensitive teeth is through prevention and good oral care habits:

• Brush twice daily with a fluoride toothpaste, using a soft-bristled brush.

• Floss once a day to keep gums healthy and prevent recession.

• Avoid overbrushing – gentle cleaning is more effective than scrubbing.

• See your dentist regularly for professional cleans and check-ups.

• Limit acidic and sugary foods/drinks that erode enamel.

Small changes in your daily routine can make a big difference to long-term comfort.

FAQs About Sensitive Teeth

Why are my teeth suddenly sensitive?

Sudden sensitivity may be due to enamel wear, a cavity, or even a cracked tooth. It’s best to book a check-up to find the cause.

Is tooth sensitivity a sign of a cavity?

It can be. Cavities expose dentine and nerves, often causing localised sensitivity or pain.

Can sensitive teeth be cured permanently?

It depends on the cause. Treatments like fillings, fluoride varnishes, or gum therapy can resolve sensitivity, but prevention is key.

Does whitening make teeth more sensitive?

Yes, temporarily. But we offer whitening systems designed to minimise or avoid sensitivity altogether.
