If you’ve recently noticed a sharp pain when drinking cold water, eating ice cream, or enjoying a hot coffee, you may be experiencing tooth sensitivity. Sudden tooth sensitivity is common and can be caused by several dental issues.
At Dural Dental Practice, we help patients understand why sensitivity occurs and provide solutions to relieve discomfort.
Here are some of the most common reasons teeth can suddenly become sensitive.
1. Worn Tooth Enamel
Tooth enamel protects the inner layers of your teeth. When enamel wears away, the underlying dentine becomes exposed, causing sensitivity.
This can occur due to:
- Aggressive brushing (using excessive force)
- Using a hard-bristle toothbrush
- Acidic foods and drinks
- Teeth grinding or clenching
Exposed dentine reacts to hot, cold, or sweet foods, triggering sharp sensations.
2. Gum Recession
When gums recede, the sensitive roots of your teeth become exposed. This can happen due to:
- Gum disease
- Aggressive brushing
- Age-related changes
Exposed roots are more vulnerable to temperature changes, causing sudden sensitivity.
3. Tooth Decay
Cavities can create small openings in your teeth that expose nerves to temperature and pressure. Early detection and treatment are essential to prevent worsening decay and discomfort.
4. Cracked or Damaged Teeth
Cracks allow hot or cold sensations to reach the inner nerve of the tooth, causing sharp or sudden pain. Prompt dental assessment can prevent the problem from worsening.
5. Teeth Whitening Treatments
Temporary sensitivity is common after professional or at-home whitening treatments. This usually improves within a few days, but persistent sensitivity should be checked by a dentist.
When to See a Dentist
You should schedule a dental visit if:
- Sensitivity lasts longer than a few days
- Pain is severe or worsening
- Sensitivity occurs when biting or chewing
- One tooth is more affected than the others
Early assessment helps prevent more serious dental issues.
Treating Tooth Sensitivity
Depending on the cause, your dentist may recommend:
- Desensitising toothpaste
- Fluoride treatments to strengthen enamel
- Dental bonding to cover exposed areas
- Treatment for gum disease
- Restorative treatments like fillings or crowns
Addressing sensitivity early can quickly improve comfort and protect your teeth.
