The short answer

How should you use whitening strips safely at home?
Read the package directions, keep strips off the gums, and do not combine them with another whitening product unless a dentist advises it. Pause use for significant sensitivity, gum burning, or ulceration.
When should a dentist check your teeth before strips?
Have a dental examination first if you have untreated decay, cracks, gum recession, enamel defects, or restorations in the visible smile. A dentist can identify the stain source and select a suitable concentration or alternative.
