Comparison questions

See how Teethfy compares to other teeth whitening methods.

Professional in-office whitening typically costs $300-$1,000 and uses high-concentration peroxide. It's faster (1-2 visits) but often causes significant sensitivity. Our strips offer gradual, comfortable whitening at a fraction of the cost with no sensitivity.

Most whitening strips use hydrogen peroxide, which can cause painful sensitivity. Teethfy uses a peroxide-free mineral salt formula that's gentle on sensitive teeth while still delivering visible results. Our strips also contain coconut oil for added enamel protection.

Whitening toothpastes are mildly abrasive and can only remove surface stains with gradual results over weeks/months. Our strips provide concentrated treatment that shows results after just one use and are significantly more effective than toothpaste alone.

LED kits use light to accelerate peroxide reactions, which can increase sensitivity. Studies show the LED light often doesn't add significant benefit beyond the peroxide gel. Our strips work effectively without any devices or batteries needed.

Custom trays from dentists can cost $300-$600 and require peroxide gel. Over-the-counter one-size trays often fit poorly. Our pre-formed strips conform perfectly to any smile and are much more convenient with no messy gels.
