Question and answer

Crest whitestrips before after reddit

Whitening-strip results vary with stain type, tooth condition, fit, and photography, so online before-and-after images are not a treatment forecast.

The short answer

Whitening-strip results vary with the starting shade, stain type, fit, wear pattern, and tooth condition, so online before-and-after photos are not a reliable treatment forecast.

Why can whitening before-and-after photos look different?

Photos can differ because of lighting, camera settings, dehydration, filters, shade, and the time between images. Sensitivity and gum irritation depend on peroxide exposure, fit, contact with the gum, and the condition of the enamel and dentine.

How can you use whitening strips more carefully?

Read the product directions, keep gel off the gums, and do not use strips over untreated decay, cracks, or inflamed gums without an examination. A dentist can identify the stain source, record a baseline shade, and discuss supervised whitening or restorative options.

When should uneven whitening or sensitivity be examined?

Seek dental care for pain, uneven colour, gum burns, white patches, or sensitivity that persists. A dark single tooth may need assessment for pulp or trauma rather than cosmetic whitening alone.

Which whitening option fits your teeth, gums, and staining?

Ask whether the colour change is intrinsic or surface staining, whether existing restorations will match afterward, and which whitening method fits your teeth and gums.

Frequently asked questions

Why did my strips not work evenly?

Uneven contact, different stain types, restorations, dehydration, or tooth anatomy can produce uneven colour.

Can strips whiten a crown?

No. A crown keeps its material colour, so whitening nearby natural teeth may make a mismatch more visible.
