Managing tooth sensitivity: Causes and effective solutions

Do you feel a sudden, sharp pain when enjoying hot, cold, or sweet foods? If so, you may be dealing with tooth sensitivity. Unlike a persistent toothache, sensitivity typically presents as brief, sharp discomfort that quickly fades. Whether it’s triggered by a sip of cold water or a bite of a sweet treat, tooth sensitivity can significantly impact your quality of life.

Sensitive teeth

Many people experience sensitive teeth. The pain is often short and sharp, quickly easing. Tooth sensitivity is different to toothache which tends to be longer lasting and ranges from a dull ache to constant pain. Some people aren’t aware they have tooth sensitivity until they eat or drink; others experience sensitivity when they feel cold air on their teeth

Causes for sensitive teeth

Tooth sensitivity happens 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. It can be difficult to determine which tooth is sensitive, and multiple teeth can be sensitive at the same time. Worn enamel or exposed tooth roots, as well as issues with the strength of a tooth, can also contribute to sensitivity. Additionally, cavities, cracks, worn fillings, or gum disease are common factors that can lead to tooth sensitivity.

Why are my teeth sensitive?

There can be many reasons for tooth sensitivity though some of the most common are decay or tooth erosion. When the protective layers of a tooth, like the enamel and gums, are damaged and worn, the inside of the tooth called the dentine is exposed. Dentine contains tiny channels that connect with the inner pulp of the tooth, where the nerve fibres that register pain are located. When hot, cold, or sweet triggers come into contact with the dentin, they can cause a sensitive or painful reaction.

Some people may experience increased tooth sensitivity after dental treatments, but this usually resolves within a day or two. Sensitivity can also result from tooth whitening, gum erosion, consuming highly acidic foods or drinks, and tooth grinding. Additionally, brushing too hard or using a side-to-side motion instead of a 45° angle can cause ‘toothbrush abrasion,’ which wears away enamel and contributes to sensitivity.

Treatments for sensitive teeth

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