Hismile colour corrector before and after
A purple colour-correcting toothpaste can make yellow tones look less noticeable briefly, but it does not bleach enamel or change restorations.
The short answer
A purple colour-correcting toothpaste can make yellow tones look less noticeable briefly, but it does not bleach enamel or change restorations. Any before-and-after difference is mainly an optical effect from complementary colour rather than peroxide whitening.
What is the direct answer?
What does this question mean?
Colour correction uses a violet or purple pigment to visually counter yellow tones on the tooth surface. The pigment is rinsed away and does not remove intrinsic colour within enamel or dentin. Abrasive ingredients may remove some surface debris, but they do not repair decay or restore enamel.
What can you do next?
Use the product exactly as its label directs and brush with a soft brush without aggressive pressure. For a lasting shade change, a dentist first checks for plaque, calculus, decay, gum disease, and restorations, then discusses peroxide whitening or restorative options when appropriate.
When should you seek dental care?
Seek dental care for pain, bleeding gums, a rough or broken tooth, a dark single tooth, or a colour change that does not match the other teeth. Stop using a product that causes persistent burning, irritation, or sensitivity and have the cause assessed.
What should you ask the dentist?
Ask whether your discolouration is surface stain, intrinsic staining, decay, or a restoration mismatch. Ask whether whitening would change the shade evenly and what treatment would address a tooth that cannot be whitened.
Frequently asked questions
Does colour corrector permanently whiten teeth?
No. The visual effect fades as the pigment is removed and it does not replace professional diagnosis of staining.
Why is one tooth still dark?
A single dark tooth may have internal staining, prior trauma, a root-canal change, decay, or a restoration and needs examination.
