Frequently Asked Questions

Get answers to common questions about Teeth Whitening.

Teeth whitening results vary widely but commonly last six months to two years. Longevity depends on diet, oral hygiene, smoking and follow-up touch-ups. We recommend occasional maintenance treatments and avoiding staining foods to preserve results and extend whitening effectiveness.

Yes—after a dental exam we choose appropriate whitening strength and apply desensitizing protocols. Our advanced system reduces sensitivity risk, and take-home options use lower concentrations for gradual whitening, keeping enamel safe under professional supervision.

Many patients see significant improvement after one in-office session; others benefit from two sessions for deeper stains. Take-home trays typically require daily use for one to two weeks. Your dentist will recommend the optimal number based on stain severity and desired shade.

Yes—coffee, tea and tobacco cause mainly extrinsic stains that respond well to professional bleaching. Deep or long-standing discoloration may require additional sessions or combined treatments. A consultation determines the best approach and whether whitening alone will achieve your desired shade.

Yes. Realtooth offers both in-office accelerated whitening for immediate, dramatic results and physician-prescribed take-home trays for gradual, controlled whitening. We can combine methods for optimal effect and advise on aftercare and touch-ups to maintain long-lasting, comfortable outcomes.

Some patients experience mild, temporary sensitivity or minor gum irritation, usually resolving within days. We use desensitizing gels, adjusted peroxide levels and protective barriers to minimize discomfort. Contact us if symptoms persist beyond a week so we can review and manage appropriately.
