Understanding Sensitivity

Sensitivity occurs when the tiny tubes, called tubules, that connect the inner layer of the enamel (dentin) to the inside of the tooth where the nerves live (the pulp) are exposed. When an aggravating substance reaches the nerve through the open tubules, it irritates the nerve, resulting in pain. Hot, cold, sweet, and acids can all cause aggravation to sensitive teeth, causing sufferers to have discomfort when eating and drinking or even when breathing in cold air. Thinning enamel, cracks from clenching and grinding, and receding gums are the most common reasons people experience tooth sensitivity.

Common Causes

  • Clenching and grinding of teeth
  • Receding gums, from disease or orthodontic treatment
  • Enamel loss
  • Untreated cavities

Treatment Options

  • Toothpaste with a desensitizing agent
  • Toothpaste that helps remineralize enamel
  • Bonding of exposed tooth surfaces
  • Treating caries

Common Questions About Sensitivity:

Does all sensitive tooth pain mean I have cavities?

Not necessarily. Although cavities frequently cause tooth pain, there are other causes. Of course, if you think you have a cavity you should see your dentist right away to treat it immediately and prevent worsening disease. Still, there are other possible causes.

It only hurts when I have cold, not hot drinks (or vice versa). Could that still be sensitive tooth pain?

Yes. Every person experiences sensitivity in their own way and has their own triggers. Some people may only have mild discomfort while others may have more pronounced pain. Some may have trouble with cold while others are bothered by hot, sweets, acidic foods, or all of those.

Could my brushing technique be causing my problem?

It’s quite possible. Brushing too hard or brushing with a toothbrush with bristles that are too hard can aggravate and injure gums, causing them to recede. Good technique helps keep your gums healthy and allows them to protect the vulnerable tooth surfaces they were designed to cover.

What Customers Are Saying
“I have been using CariFree gel toothpaste and rinse for about two years. My dentist recommended changing from my standard toothpaste and mouthwash, because my cavity incidents were so high. Since I have been on the CariFree regimen, I have not had a single cavity. This is clearly making a difference.”

How CariFree is Different

CariFree products can help interrupt the disease process a number of ways, preventing the cavities from ever forming. The unique pH correcting formula of CariFree products helps make the oral environment unfavorable for acid-loving, caries causing bacteria. The high pH from the CariFree system also protects tooth enamel from having minerals dissolved away in acidic conditions. The products contain nano hydroxyapatite which the teeth can use to repair missing minerals from the enamel, particularly in the high pH environment the products create. Xylitol, a natural, non-nutritive sweetener, has several dental benefits. It makes bacteria less able to stick together in a tough to remove biofilm. Caries causing bacteria also eat the xylitol but cannot use it for energy or to reproduce. So, the bacteria starve to death while eating xylitol.
