Tooth pain that occurs when you eat or drink something cold or hot is an indicator that your teeth are overly sensitive. It can also result from eating sour or sweet foods, and sometimes just from breathing in cold air. Usually tooth sensitivity happens when your enamel has worn down, exposing the inner part of your tooth where sensitive nerves are located. It’s important to know what kinds of things may trigger tooth sensitivity, in hopes of avoiding it in the future.
Tooth decay
Decay leads to cavities, which are holes in your teeth or damage to their structure. Tooth decay and the resulting cavities are often preventable with good dental care. If you develop a cavity, however, it’s vital to get it repaired so that area of your teeth doesn’t become overly sensitive and painful.
Gum disease
Early gum disease, called gingivitis, is usually caused by poor dental hygiene that leads to gum inflammation and redness. Your gums may bleed easily and become sore. As gingivitis worsens, your gums can recede and expose the roots of your teeth. Your roots contain nerve endings, and sensitivity will likely increase.
Trauma
Accidents to your teeth or gums may lead to sensitivity. Fractured or knocked out teeth are certainly susceptible to painful sensations in your mouth.
Teeth whitening
Many people who use teeth whitening methods complain that their teeth become more sensitive with use of these products. Some whitening techniques cause this sensation more than others, so you may have to try several if you want to pursue teeth whitening without the sensitivity.
Remedies
One way to treat this problem is to use toothpaste intended for sensitive teeth. Also, avoid foods and drinks that tend to increase your symptoms. If you do consume items that cause discomfort, gently brush your teeth afterwards to help reduce the effects.
