Is Teeth Whitening Safe for Sensitive Teeth?
Teeth WhiteningSensitivity is the most common side effect of teeth whitening. If you already wince when you drink ice water, you might be afraid that whitening is off the table. Fortunately, having sensitive teeth does not disqualify you from getting a brighter smile.
It just means you need a smarter, more careful approach. Here is how to whiten safely without the 'zing'.
Why Does Whitening Cause Sensitivity?
Whitening gels work by opening the microscopic pores in your enamel to lift out stains. When these pores are open, the nerves inside your tooth become temporarily more exposed to temperature changes, leading to those sharp flashes of sensitivity.
The Solution: Professional Guidance
Over-the-counter strips are often the worst offenders for sensitive teeth because they use a 'one-size-fits-all' approach. A dentist can customize your treatment to minimize pain by:
- Adjusting Concentration: Using a lower-strength gel over a longer period is just as effective but far gentler.
- Custom Trays: Ensuring the gel stays on your teeth and off your gums prevents irritation.
- Desensitizing Agents: Applying fluoride or potassium nitrate before or after treatment to calm the nerves.
Tips for Pain-Free Whitening
If you are planning to whiten, start using a sensitivity toothpaste (like Sensodyne) two weeks *before* your treatment. This helps build a protective barrier over your nerve endings.
During your treatment, take breaks. You don't have to whiten every single day. Skipping a day allows your teeth to rehydrate and recover.
