3 Common Causes of Tooth Sensitivity and What You Can Do to Help

Posted in Teeth Whitening

Sensitive teeth can mean a lot of different things, starting with discomfort. If the sensitivity happens on a frequent basis, you probably already avoid some of your favorite foods, chewing in certain parts of your mouth, or use oral care products to help. Here are 3 common causes of tooth sensitivity and steps you can take to eliminate them:

Whitening Toothpastes

Over the counter whitening toothpastes dominate the majority of toothpastes sold in stores. Even if you aren’t buying it on purpose, chances are you may have picked up a tube that is formulated for whitening. Since whitening toothpastes open the pores of your tooth enamel, they typically cause some type of sensitivity after using it for an extended period of time. Avoid this type of toothpaste or use one formulated for sensitivity. 

Gum Recession

Receded gumlines will expose the root surfaces, which leaves nerve fibers exposed to external stimuli. Recession can be caused by gum disease, brushing too hard, or even aggressive orthodontic treatment. Thankfully these areas can be covered either through composite bonding or gingival grafting. Fluoride varnish may also help. Your dentist can recommend the most appropriate method for your smile needs.


Tooth decay or abscessed teeth can cause sensitivity at random periods of time, when you chew on certain teeth or eat certain types of foods. The type of sensitivity that is present will depend on what is actually wrong with your tooth. A quick exam and x-ray usually provide fast answers. 

Of course, there are other common causes of tooth sensitivity, such as sinus infections, existing restorations and even gum disease. If your sensitivity lasts for more than a week without improvement, it’s time to see your dentist right away.
