If you’re reading this, you’re likely already familiar with the symptoms. Sharp shooting pains felt deep within the tooth? That’s a classic sign of sensitive teeth.

The causes 

So let’s get to the root of the problem: what causes sensitive teeth?

Simply put, teeth become sensitive when they lose tooth enamel. Cracked enamel, a loose filling, or other kinds of damage can also cause discomfort, as can tooth decay. When the inner dentine layer of a tooth gets exposed to outside elements, the result is pain, most usually in the form of an intense, often ‘sharp’ or ‘shooting’ pain. 

Sure, it’s a fairly common condition, but it can be a highly uncomfortable one too.

So what are some of the triggers that provoke the symptoms of sensitive teeth? 

Hot, cold or acidic foods

When tooth enamel is missing, hot or cold drinks or food can trigger tooth sensitivity. So can acidic foods (such as fizzy drinks), or even just sweet, sticky treats. 

Surprisingly, even some mouthwashes (especially those that contain alcohol) can cause discomfort and prolonged use can make symptoms worse over time. 

Heavy handed brushing

It’s not just what we eat or drink that provokes pain in sensitive teeth. The way we care for our teeth can have an effect too. Brushing with too much pressure, or for too long, can wear down enamel, exposing the sensitive dentine below and triggering pain. 

Regular brushing is a must of course, but so is a gentle approach. Avoid hard ‘scrubbing motions’ in favour of short, gentle strokes.  

Grinding teeth

Stress and anxiety can lead to tooth grinding or bruxism, another common cause of dental sensitivity. Grinding the teeth together wears down enamel, damaging your teeth, exposing the inside dentine to the elements.

If you think tooth grinding might be causing you problems, talk to your dentist. They can advise on the best treatment, such as mouth guards worn at night to prevent grinding. 

Bleaching

Everyone wants a brighter smile, but it can sometimes come at a cost. Home bleaching kits – and sometimes in-clinic treatments – can cause tooth sensitivity. 

If you’ve just started a bleaching treatment and you’re noticing increased sensitivity, talk to your dentist about symptoms. They may be able to find alternative processes that are more comfortable for you. 

Receding gums

Gums can recede for several reasons – brushing too hard, smoking, poor oral hygiene or excessive grinding. 

The most common cause however is simply the aging process. The usual wear and tear on our gums can be enough to cause them to recede over time, which will expose the roots and make them vulnerable to sensitivity – not to mention infections and gum disease (periodontitis) as well.

When it comes to receding gums, treatments can differ, so talk to your dentist to find out which path is best for you.  

Getting sensitive teeth sorted 

For general or intermittent dental sensitivity, some swear by a homemade saltwater mouthwash. Toothpastes for sensitive teeth also work very well (although ongoing use is required to achieve ongoing results). 

Ideally, the best cure for sensitive teeth is prevention, so be sure to maintain a good homecare program. Twice daily brushing with a soft toothbrush and daily flossing, and use of a fluoride toothpaste is a great idea. Regular checkups will help you catch the common causes of tooth sensitivity before they lead to worse problems.

If your teeth have suddenly become sensitive however, don’t wait. Make an appointment with your dentist and get it checked – it may be the sign of something worth addressing. At Simply Dental, we have a range of treatments we can offer for sensitive teeth, including the application of coatings to protect vulnerable and/or sensitive surfaces and more.
