Reasons for Teeth Sensitivity

Does an ice-cold drink or cup of hot coffee sometimes make your teeth sting? Are brushing and flossing cringe-worthy experiences? If so, it sounds like you might have sensitive teeth. Here are some possible reasons for teeth sensitivity and what you can do about it. 

What Causes Sensitive Teeth? 

In healthy teeth, enamel protects the crown of your tooth, the part that sits above the gum line. Then, a layer called cementum protects the tooth root below the gum line. If these protective layers are damaged, teeth sensitivity can occur. Here are some of the most common causes to be aware of: 

  • Enamel erosion: If the outer protective layer of your teeth wears away, the sensitive dentin underneath is exposed. Enamel can erode as a result of brushing too hard, grinding your teeth, and eating acidic food regularly. 
  • Receding gums: When the gums move away from a tooth, it can expose the root surface, which may be temperature-sensitive. Receding gums may be caused by brushing too hard, grinding your teeth, or receiving inadequate dental care that leads to gum disease. 
  • Plaque buildup: If plaque forms on an exposed root surface, tooth sensitivity may increase. 
  • Cracked teeth: A chipped or broken tooth may fill with bacteria. When this enters the pulp, inflammation and tooth sensitivity may occur. 
  • Tooth whitening products: Peroxide and baking soda, two major contributors to teeth sensitivity, are common ingredients in whitening strips, toothpaste, and other dental products. 
  • Using a mouthwash with exposed dentin: Some over-the-counter mouthwashes contain acids that irritate exposed dentin and further damage this tooth layer. If you have enamel erosion, ask your dentist about safe products you can use. 
  • Recent dental procedures: Everything from teeth cleanings to crown placement to root planing and scaling can lead to temporary teeth sensitivity. This should disappear within four to six weeks. 

How to Treat Teeth Sensitivity 

Fortunately, there are treatments for sensitive teeth. The ones you pursue depend on what’s causing your sensitivity. Your dentist may recommend the following: 

  • Desensitizing toothpaste: The compounds in this product block sensory input from the tooth surface to the nerve in your tooth, reducing sensitivity. It may take a few weeks of daily use to see results. 
  • Soft-bristled toothbrush: Learning how to brush more gently using a soft toothbrush, especially when paired with desensitizing toothpaste, could garner effective results. 
  • Fluoride treatment: An in-office gel applied to your teeth may strengthen your enamel and reduce pain when exposed to hot and cold temperatures. 
  • Dental procedures: If simple measures don’t treat your sensitivity, your dentist may recommend surgical gum grafting, bonding, dentin sealers, crowns, inlays, or root canals to eliminate the problem.
