What Causes Tooth Sensitivity & How to Treat it?
With the weather changing many notice that the cold air is causing a sharp pain at the base of a tooth. This could be the result of tooth sensitivity, but what exactly does that mean?
Tooth sensitivity can occur for many reasons
- Tooth decay AKA cavities
- Cracked teeth
- Worn fillings
- Exposed tooth root from receding gums
- Worn enamel and cementum
The leading cause of tooth sensitivity is the erosion of enamel and cementum. Your enamel is a hard substance that covers the surface of your tooth. Its job is to protect the tooth above the gum line from everyday life. The job of the cementum is quite similar except its responsibility lies beneath the gum line. The cementum covers and protects the roots as well as a more delicate layer of the tooth known as the dentin.
Dentin has small fluid-filled tubes that connect directly to nerve endings underneath the gum line. When the cementum is eroded, the dentin has a higher exposure to the elements. Which causes pain and sensitivity to hot and cold components that may not have been there before.
Fear not, having sensitive teeth is very common and treatable. The treatment you receive is based on what is causing the sensitivity. Common treatments are:
- Desensitizing toothpaste: After multiple uses, it starts to block the pain linked with sensitive teeth.
- Fluoride: This treatment is applied by your dentist to different parts of your teeth to help strengthen your enamel.
- Root Canal: If decay is present in the root. Your tooth will be cleaned out and packed with a filling. After that, a crown is set on top to protect the tooth from further damage.
- Surgical Gum Graft: This is used when root exposure is the cause of sensitivity. Soft tissue is taken from another part of your mouth and used to fill in the gaps. Since there are many types of gum recession, your oral surgeon will recommend which solution is best for your health.
With sensitive teeth it is very important to not neglect your dental hygiene; this can cause your condition to get worse as well as running the risk of developing (or worsening) gum disease. Remember to brush twice a day, floss at least once, and come in for your checkup twice a year. If you are experiencing pain due to tooth sensitivity schedule an appointment for yourself right away!
