Sensitive teeth: causes and treatment
Quick answer
Why are my teeth sensitive, and what can I do about it?
Sensitivity usually happens when the softer dentine under the enamel is exposed — from gum recession, brushing too hard, acidic food and drink, grinding or a worn filling.
Use a desensitising toothpaste twice a day for at least two weeks, and spit rather than rinse after brushing. If one tooth is sharply sensitive, or pain lingers after the cold has gone, book an examination at York House Dental Practice in West Byfleet (routine exam from £52) to rule out decay or a crack.
What you need to know
Sensitive teeth are the most common dental complaint in the UK, affecting roughly one adult in three. A brief sharp twinge to cold that stops within seconds is typical sensitivity. A dull ache that lasts, pain on biting, or pain that wakes you at night is more likely decay, a cracked tooth or a nerve problem — that needs a dentist, not a new toothpaste.
At home: brush gently with a soft brush, avoid brushing straight after acidic drinks (wait around an hour), sip fizzy drinks and fruit juice less often, and rub a little desensitising toothpaste onto the sensitive area at night. Whitening can cause temporary sensitivity that usually settles when you pause.
In the practice we can apply fluoride varnish or desensitising agents, seal exposed root surfaces with a small white filling (from £175), replace a leaking filling, or fit a night guard if grinding is the cause. Start with a check-up; gum recession is assessed by our hygiene team.
