Guide for sensitive teeth

Teethfy Whitening Strips are specifically formulated to be gentle on sensitive teeth. Our peroxide-free formula uses sea salt and coconut oil instead of harsh bleaching agents. Here's how to get the best results if you have sensitive teeth.
Why Our Strips Are Different
Traditional whitening products use hydrogen peroxide or carbamide peroxide, which can penetrate tooth enamel and irritate the nerve inside your tooth. Our mineral salt formula works differently—it gently lifts surface stains without penetrating the enamel.
Tips for Sensitive Teeth
- Start with treatments every other day for the first week
- Gradually increase to daily use as your teeth adjust
- Use a desensitizing toothpaste during your treatment period
- Apply the strips 30 minutes after brushing, not immediately after
- Avoid very hot or cold foods/drinks on treatment days
If You Experience Any Discomfort
While our peroxide-free formula minimizes sensitivity, everyone's teeth are different. If you notice any discomfort:
- Take a break for 1-2 days between treatments
- Reduce treatment time to 20 minutes
- Apply a fluoride gel or sensitive toothpaste after treatment
- If discomfort persists, discontinue use and consult your dentist
What to Expect
Most users with sensitive teeth report zero discomfort with our strips. In customer surveys, 95% of users said they experienced no sensitivity during or after treatment.
