How to Handle Tooth Sensitivity: Causes & Solutions
Does a sip of cold water or a spoonful of ice cream make you wince?
Does a sip of cold water or a spoonful of ice cream make you wince? You’re not alone. Tooth sensitivity affects millions of people and can range from a mild annoyance to a sharp, lingering discomfort. The good news? You don’t have to live with it.
At Diamondback Dentistry in North Phoenix, we’re here to help you understand what causes sensitivity and how to treat it effectively, so you can enjoy your favorite foods and drinks again—without the pain.
What Is Tooth Sensitivity?
Tooth sensitivity, also called dentin hypersensitivity, occurs when the protective layers of your teeth—enamel or cementum—wear down, exposing the softer inner layer called dentin. This dentin contains tiny tubules that lead directly to the tooth’s nerve, allowing hot, cold, sweet, or acidic foods to trigger pain.
Common Causes of Tooth Sensitivity
Several factors can contribute to enamel erosion or gum recession, both of which expose dentin and lead to sensitivity:
1. Brushing Too Hard
Using a firm-bristled toothbrush or aggressive technique can wear away enamel and irritate the gums, exposing root surfaces.
2. Gum Recession
Gum tissue can recede due to gum disease or aging, exposing the root of the tooth, which isn’t protected by enamel.
3. Tooth Grinding (Bruxism)
Clenching or grinding your teeth can slowly wear down enamel, leading to sensitivity over time.
4. Acidic Foods & Drinks
Frequent exposure to citrus, soda, vinegar, and wine can erode enamel and make teeth more vulnerable to pain.
5. Whitening Products or Harsh Toothpastes
Some whitening toothpastes or over-the-counter bleaching kits can cause temporary sensitivity, especially if used frequently.
6. Tooth Decay or Damage
Cavities, cracked teeth, or worn fillings can expose the inner layers of a tooth, resulting in sharp pain or chronic sensitivity.
How to Treat Tooth Sensitivity
At Diamondback Dentistry, Dr. Pouria Owtad offers several safe, effective treatments to help patients manage and overcome sensitivity—starting with a proper diagnosis.
1. Desensitizing Toothpaste
These over-the-counter or prescription toothpastes contain compounds that help block pain signals from the surface of the tooth to the nerve. Results typically appear after a few weeks of consistent use.
2. Fluoride Treatments
In-office fluoride applications help strengthen enamel and reduce discomfort, especially in patients with early erosion or minor sensitivity.
3. Dental Bonding or Sealants
For exposed roots or worn enamel, Dr. Owtad may apply a tooth-colored resin to protect the surface and seal off sensitivity triggers.
4. Mouthguards for Grinding
If you grind your teeth, a custom nightguard can prevent further damage and ease sensitivity, especially in the mornings.
5. Treatment for Gum Disease
If gum recession is caused by periodontal issues, scaling and root planing or other gum treatments may be needed to restore gum health and protect the roots of your teeth.
6. Addressing Underlying Issues
In some cases, a cracked tooth, deep cavity, or old filling may be to blame. Restorative treatments like fillings, crowns, or root canals can resolve pain and restore comfort.
When to See Your Dentist
If your sensitivity:
- Lingers or worsens over time
- Is triggered by pressure or biting
- Interferes with your eating or daily comfort
…it’s time to schedule a visit. Tooth sensitivity isn’t something to ignore—it can be a sign of a deeper problem that needs care.
