Understanding Tooth Sensitivity

If you experience discomfort when eating ice cream, drinking hot coffee, or even brushing your teeth, you may have sensitive teeth. Sensitivity occurs when the protective layers of the teeth wear down, exposing the dentin or nerve endings, leading to discomfort. Below, we explore the most common causes of tooth sensitivity and the science behind them.

Enamel Erosion

Enamel is the hard outermost layer of the tooth that protects against decay and sensitivity. When it wears away due to acidic foods, aggressive brushing, or acid reflux, the underlying dentin is exposed. Dentin contains tiny tubules that connect to the tooth’s nerves, allowing external stimuli like heat and cold to trigger pain.

Gum Recession

Receding gums can expose the root surface of the tooth, which lacks enamel protection. This makes teeth more susceptible to external stimuli. Gum recession can be caused by factors such as gum disease, aggressive brushing, aging, and genetics.

Cavities and Tooth Decay

Cavities result from bacterial activity breaking down tooth enamel. When decay progresses, it reaches the dentin and even the pulp, causing heightened sensitivity. Untreated cavities can lead to persistent discomfort and require fillings or root canal treatment.

Cracked or Chipped Teeth

A crack or chip in a tooth can expose the sensitive inner layers. Biting into hard foods or experiencing trauma can lead to microscopic fractures that allow external irritants to reach the nerve, causing sharp pain.

Teeth Grinding (Bruxism)

Grinding or clenching your teeth, especially at night, gradually wears down enamel. This exposes the dentin and increases sensitivity. Bruxism is often linked to stress, misaligned teeth, or sleep disorders.

Whitening Treatments with Harsh Peroxide Levels

Traditional whitening treatments, especially those with high concentrations of hydrogen or carbamide peroxide, can lead to temporary sensitivity by penetrating the enamel and reaching the dentin. While effective, they may cause discomfort in people with pre-existing sensitivity.

Post-Dental Procedure Sensitivity

After professional dental treatments like deep cleanings, fillings, or whitening procedures, temporary sensitivity is common. This occurs due to mild irritation to the dentin or nerves, but it usually subsides within a few days.

Tips for Whitening Sensitive Teeth Safely

1. Choose Lower Peroxide Concentrations – Stick to whitening products with lower concentrations of carbamide peroxide to reduce sensitivity.
2. Use Peroxide-Free Alternatives – Consider PAP+ or color-correcting formulas for a gentler whitening experience.
3. Follow the Recommended Usage – Avoid overusing whitening products, as excessive application can increase sensitivity.
4. Use a Desensitizing Gel After Whitening – Our formula specifically contains potassium nitrate to help manage sensitivity.
5. Limit Acidic Foods and Beverages – Acidic drinks like soda and citrus juices can wear down enamel, increasing sensitivity.
6. Apply a Remineralizing Gel – Using a remineralizing gel regularly can help strengthen enamel and reduce discomfort.
7. Whiten Your Teeth Before Bed – Whitening at night can help minimize sensitivity since your teeth won’t be exposed to hot or cold foods immediately afterward.
