Types of Tooth SensitivityA twinge of pain in one or more of your teeth may be the result of sensitivity—what kind is an important distinction. There are two types of tooth sensitivity: dentinal and pulpal. Dentinal sensitivity involves the dentin—the middle layer of the tooth. The protective layer of enamel or cementum wears away, exposing the dentin. This type can affect one or more teeth.
Causes of Dental Sensitivity:
- Brushing too hard
- Poor oral hygiene
- Long-term tooth wear
- Cracked filling
- Untreated cavities
- Receding gums that expose the tooth’s root
- Tooth whitening
- Over consumption of acidic food and drink
Causes of Pulpal Sensitivity:
- Decay or infection
- Recent filling
- Pressure caused by clenching and grinding
- Cracked or broken tooth
How Norge Dental Center Helps Treat Your Tooth SensitivityYour dentist will perform a thorough examination and clean your teeth. If your teeth are too sensitive, you have the option of a local anesthetic or nitrous oxide prior to the cleaning. Other follow-up treatments may include:
- Fluoride Varnish: Your dentist may apply this to protect your teeth and temporarily reduce sensitivity.
- Dental Laser: A modern treatment for sensitivity involves using a laser to alter the tubules of your teeth and reduce sensitivity.
- Root Canal: With pulpal sensitivity, your dentist may recommend a root canal if the tooth’s nerve sustains damage or dies. We remove the dead nerve and replace it with a nonreactive substance. And because a complete barrier of enamel no longer protects the tooth, the restoration necessitates a crown or composite filling.
- Plastic Night Guard: For sensitivity caused by grinding or clenching, your dentist can provide you with a plastic night guard for use while you sleep.
