Do You Have Tooth Sensitivity Problems?
Tooth sensitivity follows damage to your teeth or gums. In fact, this damage usually includes thinned tooth enamel or receding gums. Sensitivity provides a sign that your underlying tooth surface has been exposed. It also clarifies you need to visit your dentist.
Signs and Symptoms of Tooth Sensitivity
Sensitivity in your teeth causes discomfort or pain when drinking or eating hot, cold, sweet, or acidic substances. Moreover, it also occurs when breathing in cold air. Sometimes the sensitivity comes and goes over a span of time.
The Academy of General Dentistry (AGD) reports that about 40 million American adults suffer tooth sensitivity. This means about one in every eight people share this problem. The pain is a symptom of a number of possible dental problems.
Why Your Teeth Become Sensitive
Dentin is your tooth’s inner portion; a material containing thousands of microscopic tubes housing nerve endings. Dentin extends from the crown of your teeth to their roots. Your tooth enamel protects these nerve endings in the crown. Cementum, below or above your gum line, performs the same job on your roots.
The sensitivity you feel comes from exposed dentin. Specifically, your tooth that aches have lost its protective coating. You discover your tooth vulnerability through the pain.
Your sensitivity signals a problem. For example, possible problems include:
- Worn enamel damaged during aggressive tooth brushing
- Tooth erosion from highly acidic drinks or foods
- Tooth decay, broken teeth, or worn fillings
- Receding gums exposing your tooth roots
- Teeth grinding
- Temporary sensitivity from dental treatment, such as teeth whitening
