Hismile before and after real
Before-and-after whitening images can show a change in tooth shade, but results vary with the starting stain, product use, lighting, photographs, and whet.
The short answer
Before-and-after whitening images can show a change in tooth shade, but results vary with the starting stain, product use, lighting, photographs, and whether restorations are present.
What is the direct answer?
What does this question mean?
Whitening products use peroxide or other chemistry to alter some stains in natural enamel and dentine; they do not whiten porcelain or composite restorations.
What can you do next?
Check the ingredient and instructions, photograph teeth in consistent lighting, and have discoloured teeth or restorations assessed before judging the result.
When should you seek dental care?
See a dentist for pain, one dark tooth, gum burns, uneven colour, or little change after correct use, since the underlying cause may need treatment.
What should you ask the dentist?
Ask whether the product matches your type of discolouration, what result is realistic for your enamel, and how existing fillings or crowns will affect the final shade.
Frequently asked questions
Why can my result differ from online photos?
Lighting, camera settings, dehydration, starting shade, application technique, and editing can all change how a shade appears.
Will whitening change my fillings?
No. Restorative materials keep their colour, so a later replacement may be discussed if the tooth and restoration no longer match.
