Sensitive Teeth – Causes and Treatments
Unexpected pain or discomfort when consuming hot or cold food and drinks, or when you breathe through your mouth, are common symptoms of sensitive teeth. The good news is, it’s also treatable –and with our helpful guide you can discover the main causes, symptoms and best ways to manage tooth sensitivity.i
Visit your dentist if tooth sensitivity lasts more than a few weeks.ii
What Is Tooth Sensitivity?
If you get a short, sharp, painful sensation in your teeth when you bite into an ice cream, take a sip of an icy drink or slurp a mouthful of hot soup, chances are you have sensitive teeth.i
Tooth sensitivity is an exaggerated response to stimuli such as hot, cold, sweet or acidic foods and drinks, exposure to cold air and even brushing your teeth.i, ii
What Do Sensitive Teeth Feel Like?
Symptoms of sensitive teeth can range from a mild twinge to considerable discomfort. Pain can come and go, and may be worse on some occasions than others.ii Depending on the cause of your sensitivity, you may not feel pain in every tooth.
Why Is My Tooth Hurting?
To understand the answer to this question, it helps to know a little about the structure of your teeth. Each tooth consists of the crown, which is the visible part of the tooth, and the root, which anchors each tooth into your jaw. Components of the crown include:iii
- Tooth enamel – The hard, white-looking layer that protects the sensitive inner parts of each tooth. Tooth enamel is the hardest material in your body – even stronger than bone.iv
- Cementum – A thin, protective layer of bone-like tissue under the gum line that protects the tooth root.
- Dentin – A layer of softer tissue which contains tiny canals or ‘tubules’.
- Pulp – The soft tissue deep inside each tooth that contains blood vessels, connective tissue and nerves.
If for any reason the enamel starts to wear way or erode, your tooth’s dentin is exposed. When this happens, nerve signals pass to the tooth root and from there to the brain – meaning that things like eating popsicles or drinking hot drinks, which normally don’t cause a reaction, can suddenly trigger pain.i
What Causes Sensitive Teeth?
A range of factors can lead to tooth sensitivity, but there are two main underlying reasons: enamel loss and gum recession.ii
Causes of enamel loss include: ii
- Over-zealous brushing: Brushing too vigorously or too often.
- Acid erosion: From acidic foods and drinks such as sugary sports drinks and sodas.
Causes of gum recession include:ii, v
- Using a hard bristle toothbrush – This can injure the gum tissue.
- Gum disease – A common oral health disease that can cause receding gums.
- Your genes – Regardless of how you care for your teeth, you may be genetically susceptible to gum recession.
- Smoking – Tobacco products increase plaque build-up on teeth which over time can lead to a greater risk of gum recession.
Professional and at-home teeth whitening (bleaching) treatments may cause temporary sensitivity, although this should disappear within a short time of stopping treatment.vi Learn more about whitening sensitive teeth.
