Do you experience a sharp, sudden, shooting tooth pain when you eat hot, cold, or sweet foods—or breathe cold air? If the answer is “yes,” you may have sensitive teeth, or dentinal hypersensitivity. It’s a common dental complaint for millions of Americans, and impacts 1 out of 5 adults. The discomfort can range from mild to unbearable and last a few days to months.  Prolonged and acute pain that prohibits normal chewing and eating requires a prompt call to your dentist.

Causes of Tooth Discomfort

Sensitivity often occurs when the dentin, or the underlying layer of your teeth, is exposed.  This allows stimuli—food, drink or air—to travel through the exposed dentin and down to the nerve in the center of the tooth, resulting in pain.  There are a number of factors that lead to irritated or sensitive teeth, such as:

• Improper brushing techniques: Using a hard bristle toothbrush or brushing too hard can wear down the enamel, which protects the dentin.
• Receding gums:  Improper brushing technique, and gum disease (periodontitis) can cause gums to pull away from the teeth and lead to sensitive exposed root surfaces.
• Teeth grinding or clenching jaws: Also known as bruxism, tooth grinding can fracture and wear away the enamel, exposing the  more sensitive dentin layer. In addition, the excessive forces applied to the tooth can inflame the nerve inside.
• Acidic foods: Citrus fruits, vegetables high in acids and tea can eat away at the tooth’s enamel.
• Trauma: Injuries or cracked teeth allow bacteria to attach to teeth and creep into the pulp, causing inflammation.
• Broken or damaged fillings or crowns: …...
• Cavities:…...

Treatment of Sensitive Teeth

Fortunately, there are many forms of treatments to reduce or prevent sensitive teeth. Some simple changes can make a big difference right away, like replacing your toothbrush with a soft bristle or an electric toothbrush. This helps control the pressure applied to teeth while you brush. Switching to desensitizing toothpaste can numb the pain, and fluoride mouthwash can help to protect tooth enamel. It’s also critical to practice good oral hygiene and attend regular dental visits.
