How fast are the results?
In-office whitening can brighten your teeth by up to eight shades in a single visit, usually around two hours. Custom take-home kits show noticeable results in about two weeks. OTC products like strips or gels may take several weeks and offer more modest results.
Which method delivers the most dramatic result?
In-office whitening treatments offer the most immediate and dramatic improvements in tooth shade because they use the highest strength whitening agents with professional supervision.
Are there benefits to professional take-home whitening over OTC kits?
Yes. Take-home kits from the dentist come with custom trays that fit your teeth precisely, allowing even gel distribution and more effective whitening. The gel is also stronger and more reliable than what’s found in store-bought kits.
Is professional whitening safer than at-home options?
Yes. Dentists use protective barriers and controlled concentrations to reduce sensitivity and protect gums. OTC products can irritate gums or cause uneven whitening if used incorrectly.
How long do results last?
Results from in-office whitening typically last one to three years with proper care. Professional take-home trays offer similar longevity with occasional touch-ups. OTC product results may fade sooner and require frequent reapplication.
Will whitening work on all types of stains?
Whitening is most effective on yellow stains caused by aging, food, and drink. It’s less effective on gray or internal stains, such as those caused by medication or trauma. For those, cosmetic treatments like veneers may be a better option.
What maintenance steps help keep teeth white?
To maintain results, avoid or limit staining foods and beverages, don’t smoke, brush and floss regularly, rinse after meals, and schedule touch-up treatments as needed. Regular cleanings at the dentist also help maintain brightness.
