TOOTH SENSITIVITY

https://offerforge.net/?a=28162&c=315733&s1=

Tooth sensitivity is one of the most common dental problems reported by patients globally.
Also known as dentin hypersensitivity, tooth sensitivity occurs when the root surfaces of teeth are exposed. This occurs when the enamel that protects our teeth gets thinner, or when there is gum recession.  The underlying surface, the dentin are then exposed. And this reduces  the protection the enamel and gums provide to the tooth and root.

Causes of tooth sensitivity

There are many causes of tooth sensitivity, including:

• Worn tooth enamel from using a hard toothbrush or brushing too aggressively
• Tooth erosion due to highly acidic foods and beverages
• Tooth erosion due to bulimia or gastroesophageal reflux disease (GERD)
• Gum recession that leaves your root surface exposed

Prevention of tooth sensitivity

The following are some at-home treatments that are commonly advised by dental professionals:

• Desensitizing toothpaste. There are several brands of toothpaste for sensitive teeth available. Your dentist may recommend one or you may have to try different brands until you find the product that works for you. Be sure to use fluoridated toothpaste for sensitive teeth, not tartar-control toothpaste. Try spreading a thin layer of the desensitizing toothpaste on the exposed tooth roots before bed.
• Use a soft-bristled toothbrush.
• Avoid highly acidic foods.
• Use a fluoridated mouthwash daily.
• Avoid teeth grinding. Consider getting a mouth guard.

Treatment of tooth sensitivity

If you have sensitive teeth, don’t neglect your daily oral care routine. Just be sure to use a soft toothbrush and soft floss. You can also try a toothpaste designed for sensitive teeth. Several brands are available, and you should notice some improvement with regular use of any of them. Also, try spreading some sensitizing toothpaste along the exposed cementum or dentin area before bed to help reduce sensitivity. Just use your fingertip or a cotton swab to rub the toothpaste directly onto the exposed spot.

  In addition there are some dental procedures that may reduce tooth sensitivity:

• Bonding, crowns or inlays. These may fix a tooth flaw or decay that is causing sensitivity.
• Fluoride gel or varnish.
• Surgical gum graft. This will protect the root and reduce sensitivity if the gum tissue has eroded from the root.
• Root canal. This is a last-resort treatment for severe tooth sensitivity that has not been helped by other methods.
