Teeth Whitening: Frequently Asked Questions

Are whitening products more effective on teeth with stains of certain colors?

Yes. Yellowish teeth respond well to bleaching, brownish-colored teeth respond less well, and grayish-hue or purple-stained teeth may not respond well to bleaching at all. Blue-gray staining caused by tetracycline is more difficult to lighten and may require up to 6 months of home treatments or several in-office appointments to successfully lighten. Teeth that have dark stains may be better candidates for another lightening option, such as veneers, bonding, or crowns. Your dentist can discuss the options best suited for your situation.

 

How often do the teeth whitening need to be touched up?

Whitening is not permanent. People who expose their teeth to a lot of foods and beverages that cause staining may see the whiteness start to fade in as little as 1 month. Those who avoid foods and beverages that stain may be able to wait 1 year or longer before another whitening treatment or touch-up is needed. Shop our whitening kit here

 

Are there any risks associated with teeth whitening?

The two most common side effects are a temporary increase in the sensitivity of the teeth and a slight inflammation of the soft tissues of the mouth, especially the gums. Tooth sensitivity often occurs during the early stages of bleaching. Tissue pain is most commonly caused by an inappropriate mouthpiece tray rather than a tooth-bleaching agent. Those two symptoms are usually temporary and resolve within 1 to 3 days of discontinuation or completion of therapy.

 

Do teeth whiteners damage existing dental restorations?

Over 10 years of clinical use of whitening products containing 10% carbamide peroxide have not shown any damage to existing fillings. The issue is not “damage” to existing restorations; rather, keep in mind that existing restorations such as tooth-colored fillings, crowns, bonding, veneers, and bridges do not lighten. This means that any preexisting dental work may need to be replaced to match the new tooth shade achieved in the natural teeth, should a bleaching process proceed.

Do teeth whiteners damage a tooth’s nerve?

With all types of bleaching procedures, the degree of whiteness will vary from individual to individual depending on the condition of the teeth, nature of the stain, the concentration of the bleach and the duration of time and bleaching system used.
