If drinking cold water or eating ice cream causes a sharp, brief pain, you likely have tooth sensitivity. This condition is very common and, in most cases, treatable. Your dentist in Sainte-Marthe-sur-le-Lac helps you identify the cause and find a solution.
Quick Answer
- Cold sensitivity is caused by exposed dentin beneath the enamel
- Common causes: worn enamel, receding gums, cavity, or crack
- Sensitivity toothpaste can relieve mild cases
- Professional treatments exist for persistent cases
- Consult if pain is intense or lasts more than a few seconds
Why Are My Teeth Sensitive to Cold?
Beneath your teeth's protective enamel lies dentin, a tissue filled with tiny tubes leading to the nerve. When dentin is exposed — through enamel wear or gum recession — stimuli like cold can reach the nerve and cause a brief but sharp pain.
Common Causes
Enamel Erosion
Aggressive brushing, acidic foods (citrus, carbonated drinks, vinegar), and acid reflux gradually wear down enamel.
Gum Recession
When the gum pulls back, the tooth root is exposed. The root lacks enamel and is more sensitive to temperature.
Tooth Decay
Even early decay can cause sensitivity, especially to cold and sweets.
Cracked Tooth
An invisible microcrack can cause sharp cold pain. It requires a professional exam to detect.
Recent Whitening
Temporary sensitivity is normal after whitening. It should fade within a few days.
Solutions and Treatments
At Home
- Use sensitivity toothpaste (containing potassium nitrate or stannous fluoride)
- Brush gently with a soft-bristled brush
- Avoid very acidic foods
- Wait 30 minutes after an acidic meal before brushing
At the Clinic
- Fluoride varnish application to strengthen enamel
- Sealant or resin on exposed areas
- Gum graft if recession is significant
- Root canal if the nerve is compromised
Frequently Asked Questions
Will cold sensitivity go away on its own?
Mild cases may improve with the right toothpaste. If pain persists for more than a few weeks or intensifies, see your dentist.
Does sensitivity mean I have a cavity?
Not necessarily, but it's one possible cause. A professional exam helps distinguish simple sensitivity from a cavity or crack.
