Ask A Perth Dentist; What Causes Sensitive Teeth?

Countless people across the world are living with sensitive teeth. Whether it’s holding you back from enjoying that ice cream or forcing you to drink your tea at lukewarm, dental sensitivity can get in the way of your lifestyle. Even a breath of chilly winter air can cause sharp pains to shoot through your teeth – but why do some people get sensitive teeth? We’ve asked the best dentist in Perth for some advice.

Teeth Grinding

Grinding your teeth, or bruxism, can cause sensitive teeth – and some people may not even know that they’re doing it. 80% of bruxism occurs while people are asleep, and it is far less common to grind or clench your teeth while you’re awake. This constant wearing can cause the enamel to deteriorate, exposing the nerve centre to sharp signals.


It is more common for people to experience sensitive teeth as they age, usually related to lifestyle choices and general wear-and-tear of the teeth. However, there are still people across all ages groups who are affected by sensitive teeth.

Vigorous Dental Hygiene

Sometimes, you can have too much of a good thing. Tooth sensitivity can arise from brushing too forcefully and wearing down the tooth, leaving the microscopic nerve tubules exposed. It can also come from tooth-whitening toothpastes, where the added chemicals cause discomfort and sensitivity for some people.


If we don’t floss and brush regularly, plaque can build up and erode the enamel which protects the tooth. Fortunately, regular dental hygiene and dentists visits can manage this.

Acidic Foods

Acidic foods, such as lemon, pickles, and tomato sauce can all wear down enamel and cause pain to exposed nerve endings.

Gum Disease

Gum disease can cause receding gums, which exposes more of the tooth to aggravating external factors. Gum diseases such as gingivitis can be the cause of tooth sensitivity, but the disease can be treated effectively and your dentist may suggest a treatment to seal your teeth.

Cracked Or Chipped Teeth

A tooth that has been chipped or cracked may have many underlying concerns, not just sensitivity. If you have a damaged tooth that is causing you discomfort, it is recommended to visit your dentist to determine appropriate treatment.

Decayed Fillings

As time passes, dental fillings may weaken around the edges, or begin to fracture. In these small cracks, harmful bacteria can begin to collect and begin to break down the enamel. Visit your dentist to treat this problem – usually your dentist can easily replace your filling and solve your tooth sensitivity.

Recent Procedure

Teeth can become sensitive after a trip to the dentists, and it is quite common. Listen to your dentist’s advice for your personal dental follow-up care for extra safety, and if sensitivity continues for an extensive period, you may wish to book another dental appointment to ensure that there are no major issues.
