Tooth sensitivity to cold drinks is a common dental problem. It usually causes a short, sharp pain when drinking cold liquids or eating cold foods. In many cases, it is a sign that the protective layers of the tooth have been worn down or that the gums have receded.
What Causes Cold Sensitivity?
Cold sensitivity happens when the inner layer of the tooth (dentine) becomes exposed. Dentine contains tiny tubules that lead directly to the nerve of the tooth, which react to temperature changes.
Common causes include:
- Gum recession exposing the tooth root
- Enamel wear from brushing too hard or acidic foods and drinks
- Tooth decay
- Cracked or worn teeth
- Teeth grinding or clenching (bruxism)
Identifying the underlying cause is important, as treatment will depend on the reason for the sensitivity.
Gum Recession and Enamel Wear
Gum recession is one of the most common causes of cold sensitivity. When gums recede, the root surface of the tooth is exposed, which is more sensitive than enamel.
Enamel wear can also develop over time due to:
- Acidic foods and drinks
- Aggressive brushing techniques
- Teeth grinding or clenching
Once enamel is lost, it cannot regenerate naturally, so early intervention is important.
When Sensitivity May Indicate a Problem
Mild, occasional sensitivity can be normal. However, persistent or worsening symptoms may indicate an underlying dental issue such as decay or a cracked tooth.
You should book a dental appointment if:
- Sensitivity lasts more than a few seconds
- Pain is increasing over time
- Only one tooth is affected
- There is pain when biting or chewing
How Tooth Sensitivity Is Treated
Treatment depends on the cause but may include:
- Desensitising toothpaste
- Fluoride treatments to strengthen enamel
- Treatment of decay
- Management of gum disease
- Bite protection such as a night guard for grinding
At Dental House Pinner, a full examination helps identify the cause so the most appropriate treatment can be provided.
Preventing Tooth Sensitivity
You can reduce the risk of sensitivity by:
- Using a soft-bristled toothbrush
- Brushing gently twice a day
- Reducing acidic foods and drinks
- Using fluoride toothpaste
- Attending regular check-ups and hygiene appointments
Preventive care helps detect early signs of gum recession or enamel wear before symptoms worsen.
