A sharp feeling when drinking something cold can be frustrating. Sensitivity has several possible causes, so recurring or worsening pain is worth discussing with a dentist.
What should I notice?
Note whether sensitivity affects one tooth or several, how long it lasts and whether sweet food or biting also triggers pain. Tell your dentist about a recent filling, a cracked tooth or changes to your gums.
Why is an examination useful?
Sensitivity can occur alongside tooth decay, gum problems or damaged dental work. Symptoms alone cannot establish the cause. A dentist can examine the tooth and discuss whether further tests or treatment are appropriate.
What can help in the meantime?
Ask the dental team about a toothpaste intended for sensitive teeth and a gentle brushing technique. Follow product instructions and do not scrub hard. Avoid repeatedly testing a painful tooth with very cold drinks.
When should I seek help sooner?
Arrange a dental appointment for persistent toothache, pain on biting, fever, a bad taste or swelling. Seek emergency care if swelling affects breathing or swallowing. If you are unsure how quickly you need to be seen, call a dental professional.
