Why Does My Tooth Ache When I Drink Cold Water?
Experiencing sharp pain when drinking cold water can be both surprising and uncomfortable. This common issue often points to tooth sensitivity, a condition that affects many people. In Singapore, more than half of the population may be affected by tooth sensitivity. Understanding the causes and treatments for tooth sensitivity can help alleviate this discomfort and prevent future occurrences.
What is Tooth Sensitivity?
Tooth sensitivity, also known as dentine hypersensitivity, is a condition characterised by discomfort or pain in the teeth when exposed to certain stimuli, such as cold, hot, sweet, or acidic foods and beverages. The pain is usually sharp and sudden but temporary, occurring when the underlying layer of the teeth, called dentine, becomes exposed. Dentine contains tiny tubules filled with fluid that communicate with the nerve endings in the tooth. When the fluid in these tubules moves, it triggers a pain response in the nerve, leading to sensitivity.
What Can Cause Tooth Sensitivity
Several factors can contribute to the development of tooth sensitivity:
- Enamel Erosion: The enamel is the hard outer layer that protects the teeth. Over time, acidic foods, drinks, and poor oral hygiene can erode the enamel, exposing the dentine.
- Cracked or Chipped Teeth: Physical damage to the teeth, such as cracks or chips, can expose the dentine and lead to sensitivity.
- Teeth Grinding (Bruxism): Grinding or clenching the teeth can wear down the enamel and expose the dentine, causing sensitivity.
- Gum Recession: Gum recession can occur due to gum disease, aggressive brushing, or ageing. When the gums recede, the roots of the teeth become exposed, leading to sensitivity.
- Dental Procedures: Some dental procedures, such as teeth whitening, fillings, or crowns, can temporarily increase tooth sensitivity.
What Can You Do to Treat Tooth Sensitivity?
Fortunately, there are several ways to manage and treat tooth sensitivity:
- Desensitising Toothpaste: Specially formulated toothpaste for sensitive teeth can help block the pain signals from the tooth surface to the nerve. Regular use can reduce sensitivity over time.
- Good Oral Hygiene: Maintaining good oral hygiene is crucial in preventing tooth sensitivity. Brush twice daily with a soft-bristled toothbrush and use fluoride toothpaste. Floss daily to remove plaque and food particles between teeth.
- Dietary Changes: Limit the intake of acidic foods and drinks, such as citrus fruits, fizzy drinks, and wine, which can erode enamel. Rinse your mouth with water after consuming these items to neutralise acids.
- Lifestyle Changes: Limit your intake of very cold beverages. Using a straw can help to minimise contact with sensitive areas and reduce discomfort.
- Dental Treatments: If your sensitivity is severe or persistent, your dentist may recommend treatments to cover the exposed dentine.
- Fluoride Treatment: Fluoride helps strengthen the enamel and reduce sensitivity. Your dentist may recommend a fluoride gel or varnish applied directly to the teeth.
- Mouthguards: If you grind your teeth, wearing a mouthguard at night can protect your teeth from further damage and reduce sensitivity.
When Should You Consult a Dentist?
While some tooth sensitivity can be managed with at-home treatments, there are times it can be a symptom of a larger problem requiring professional attention. Consult a dentist if:
- The sensitivity persists despite using desensitising toothpaste and maintaining good oral hygiene.
- The pain is severe, affecting your ability to eat or drink comfortably.
- There are visible signs of decay, cracks, or damage to your teeth.
- You experience sensitivity in combination with other symptoms, such as swelling, redness, or bleeding gums.
- Over-the-counter treatments do not alleviate the discomfort after a few weeks.
Ignoring tooth sensitivity can lead to worsening pain and potential complications. For prompt diagnosis and treatment, schedule a visit with a dentist if you experience any concerning symptoms.

Frequently Asked Questions
Tooth pain when drinking cold water is often due to exposed dentine, which can occur from enamel erosion, gum recession, cavities, or cracked teeth, making the nerves more susceptible to cold stimuli.
Use desensitising toothpaste, apply fluoride treatments, maintain good oral hygiene, and avoid acidic foods and drinks. If the sensitivity is severe or persists despite at-home treatments, consult a dentist for further evaluation and treatment options.
Sudden sensitivity to cold can be caused by new cavities, recent dental work, gum recession, or a cracked tooth exposing the dentine.
Yes, with proper treatment such as using desensitising toothpaste, improving oral hygiene, and addressing underlying dental issues, sensitivity can be reduced or eliminated.
There are several ways to manage tooth sensitivity caused by cold water: using desensitising toothpaste, rinsing with fluoride mouthwash, avoiding acidic foods and drinks, and maintaining good oral hygiene.
Desensitising toothpaste, fluoride treatments, a cold compress on the cheek, and avoiding cold or acidic foods can help. If you experience persistent or severe pain, please consult a dentist.
Not always. While cavities can cause sensitivity, other factors like enamel erosion, gum recession, or cracked teeth can also be the culprits.
With proper care, sensitivity can improve in a few weeks. If it persists beyond that, consult a dentist for further evaluation.
Pain from cold temperatures usually indicates exposed dentine or nerves, often due to enamel erosion, gum recession, or dental issues like cavities.
No, tooth sensitivity to cold doesn't always mean a root canal is needed. It could be due to less severe issues like enamel erosion or gum recession. A dentist can diagnose the cause and recommend the most suitable treatment.
No, enamel does not regenerate once it's worn away. However, fluoride treatments can help strengthen existing enamel and prevent further erosion.
Use desensitising toothpaste, maintain good oral hygiene, avoid acidic foods and drinks, and rinse with fluoride mouthwash.
This could be due to a cavity, a crack in the tooth, or gum recession exposing the dentine and making it sensitive to cold.
Both are uncomfortable, but sensitivity to heat can sometimes indicate more serious issues like pulpitis, while cold sensitivity is often related to enamel or dentine exposure. Consulting a dentist is important to determine the underlying cause.
Ignoring tooth sensitivity is not advisable, as it can indicate underlying dental issues that may worsen over time without treatment. Early diagnosis and treatment is important to prevent complications.
