Tooth Sensitivity: Common Causes and When to Seek Advice
It might start with a small twinge.
You take a sip of iced water, enjoy your morning coffee, or bite into something sweet—and suddenly there's a quick, sharp pain in one of your teeth.
Many people ignore it, hoping it will disappear on its own. Sometimes it does. But when tooth sensitivity keeps coming back, it's worth paying attention.
At Aura Dentists Cranbourne, we often see patients who thought sensitivity was just something they had to live with. In reality, it's usually a sign that your teeth need a little extra care.
Why Do Teeth Become Sensitive?
Healthy teeth are protected by a strong outer layer called enamel. Beneath that sits dentine, which contains tiny pathways leading to the tooth's nerve.
When enamel wears down or the gums recede, those pathways become exposed. That's when everyday things like hot drinks, cold foods, or even brushing can trigger discomfort.
Sensitivity isn't a condition by itself—it's a symptom that tells us something may be affecting your oral health.
Common Reasons You May Have Sensitive Teeth
Every patient is different, but some of the most common causes include:
Enamel Wear
Over time, acidic foods, soft drinks, or brushing too firmly can gradually wear away enamel.
Gum Recession
As gums recede, the tooth roots become exposed, making them much more sensitive.
Tooth Decay
A cavity doesn't always cause severe pain at first. Sometimes sensitivity is the earliest sign.
Teeth Grinding
Grinding or clenching your teeth while sleeping can slowly wear down enamel without you even noticing.
Small Cracks in a Tooth
Even tiny cracks can allow temperature changes to reach the sensitive inner part of the tooth.
When Is It Time to See a Dentist?
Occasional sensitivity may not always require treatment, but it's worth booking a dental appointment if:
One tooth becomes noticeably sensitive
The discomfort lasts for several days
Eating and drinking become uncomfortable
Sensitivity continues to get worse
You notice swelling or pain while biting
Finding the cause early often helps prevent more complex dental problems later.
What Can Help Reduce Tooth Sensitivity?
Treatment depends on the reason behind your symptoms.
Your dentist may recommend:
A professional dental examination
Fluoride treatments
Desensitising toothpaste
Restoring worn or damaged teeth
Treating cavities
A custom mouthguard if grinding is contributing to enamel wear
The goal is to protect your teeth while making everyday activities comfortable again.
Everyday Habits That Can Protect Your Teeth
Looking after sensitive teeth doesn't always require major changes.
Simple habits often make a big difference:
✔ Brush gently using a soft toothbrush.
✔ Limit acidic foods and sugary drinks.
✔ Avoid brushing immediately after acidic meals.
✔ Wear a mouthguard if you grind your teeth.
✔ Keep up with regular dental check-ups.

Frequently Asked Questions
1. Why do my teeth suddenly feel sensitive?
Sensitivity can develop when enamel becomes thinner, gums recede, or a tooth becomes damaged or decayed.
2. Can tooth sensitivity go away by itself?
Mild sensitivity may improve, but ongoing or worsening discomfort should be professionally assessed.
3. Is tooth sensitivity always caused by cavities?
No. Sensitivity may also be linked to enamel wear, gum recession, teeth grinding, or small cracks.
4. Can using a different toothpaste help?
Desensitising toothpaste may reduce discomfort for some people, although it's still important to identify the underlying cause.
5. When should I book a dental appointment?
If sensitivity lasts more than a few days, becomes more frequent, or affects only one tooth, it's a good idea to arrange a dental examination.
