Managing tooth sensitivity: causes and effective solutions

Do you experience a sudden, sharp pain when you enjoy hot, cold, or sweet foods? This might be a sign of tooth sensitivity. Unlike a persistent toothache, sensitivity usually feels like a brief, sharp discomfort that fades quickly. Whether it’s from a sip of cold water or a bite of something sweet, tooth sensitivity can make it hard to fully enjoy those small, everyday pleasures.

Sensitive teeth

For those with sensitive teeth, the pain often strikes quickly and sharply but eases soon after. Unlike a toothache, which usually lasts longer and ranges from a dull ache to constant pain, tooth sensitivity tends to be brief. Some people don’t realise they have tooth sensitivity until they eat or drink, while others notice it when they feel cold air on their teeth.

Causes for sensitive teeth

Tooth sensitivity occurs when a tooth reacts to triggers like hot, cold, or acidic foods and drinks, cold air, sugary treats, or even the touch of a toothbrush. Identifying which tooth is sensitive can be challenging, and multiple teeth might be sensitive at once. Factors such as worn enamel, exposed tooth roots, and issues with the strength of a tooth contribute to sensitivity. Additionally, cavities, cracks, worn fillings, or gum disease often lead to tooth sensitivity.

Why are my teeth sensitive?

There are many different causes of tooth sensitivity, but decay and tooth erosion are two of the most common reasons. When the protective layers of a tooth, like enamel and gums, get damaged or worn away, the inner part called ‘dentine’ gets exposed. Dentine has tiny channels that link to the inner pulp of the tooth, where the nerve fibers that sense pain are located. When hot, cold, or sweet things touch the dentine, they can trigger a sharp, sensitive reaction.

Some people find that their tooth sensitivity increases after dental treatments, but it usually goes away within a day or two. Sensitivity can also be caused by tooth whitening, gum erosion, eating or drinking highly acidic substances, and tooth grinding. Plus, brushing too hard or using a side-to-side motion instead of a 45° angle can lead to ‘toothbrush abrasion,’ which wears down enamel and adds to sensitivity.

Treatments for sensitive teeth

If you have sensitive teeth, book an appointment with your dentist to pinpoint the cause of your discomfort. Avoiding hot, cold, or sweet foods may provide temporary relief. Maintain good oral hygiene by using fluoride toothpaste, brushing twice daily, and flossing. Opt for warm water and steer clear of foods that trigger sensitivity.
