Tooth sensitivity can impact a lot of things, including even your quality of life. This doesn’t have to be the case. We want to educate you on the possible causes of tooth sensitivity, as well as possible treatments, in order to eliminate any confusion and provide answers.
Causes of Tooth Sensitivity:
According to the online Mouth Healthy article, “Sensitive Teeth,” possible causes of tooth sensitivity are the following:
Tooth decay (cavities)
- Fractured teeth
- Worn fillings
- Gum disease
- Worn tooth enamel
- Exposed tooth root
Chad Birt wrote an ADA recommended online article in “Woman’s World” entitled, “Top Dentists Reveal How to Stop Sensitive Teeth Pain — Fast!” In it, he cites Kristy Gretzula, DDS who explains that tooth sensitivity is typically caused by two things–exposed dentin and gum recession. Dentin is the softer, inner layer of the teeth, and can be exposed as tooth enamel wears down (i.e. from brushing too hard, eating acidic foods, or grinding your teeth). And since dentin connects to nerves inside the teeth, irritation can result from temperature changes or acidic foods. In addition, gum recession (i.e. from gum disease or brushing too hard) leads to the exposure of tooth roots, and these roots can be very sensitive to temperature change and touch.
Treatments for Tooth Sensitivity:
The ADA Mouth Healthy article, “Sensitive Teeth” recommends the following treatments depending upon the source of your tooth sensitivity:
- Proper oral hygiene: This is key to preventing sensitive-tooth pain, and involves brushing twice a day for two minutes each time, and flossing at least once daily.
- Desensitizing toothpaste: Toothpastes that contain potassium nitrate help reduce the frequency and severity of sensitivity, usually after several applications.
- Fluoride gel: This in-office technique strengthens tooth enamel and reduces the transmission of sensations.
- A crown, inlay, or bonding: These address the flaws or decays that can be impacting sensitivity.
- Surgical gum graft: This procedure protects the tooth root if gum tissue has been lost.
- Root canal: This treatment may be recommended if sensitivity is severe and persists even after other treatment methods.
A summary of some additional recommendations mentioned in Birt’s article are the following:
- Choose your toothbrush/toothpaste carefully and use proper brushing techniques: Choose a soft-bristle toothbrush, and preferably an electric one, which removes up to 70% more plaque. Prevent gum damage by not brushing too hard. We recommend you talk to your hygienist to review proper brushing techniques. Dr. Khan, cited in Birt’s article, also recommends toothpastes with a lower abrasiveness (70 or lower) on the RDA scale (Relative Dentin Abrasivity).
- Sip with a straw and cut back on acid: When you drink hot and cold beverages with a straw, you minimize the time your teeth are exposed to temperature fluctuations, says Dr. Khan. She also recommends reducing the consumption of acidic foods and drinks (i.e., soda and energy drinks) to prevent enamel erosion.
- Ask your dentist about a night guard: Teeth grinding can lead to gum and enamel erosion, and thus tooth sensitivity. A night guard serves as a protective barrier between your upper and lower teeth.
You don’t have to live with ongoing tooth sensitivity. There are treatment options available, no matter the cause. We at Boulevard Dental will help you identify the causes of your tooth sensitivity and what treatment options might be best for you!
