Teeth bleaching before and after reddit
Before-and-after whitening results vary with the original stain, enamel, peroxide protocol, restorations, and camera lighting.
The short answer
Before-and-after whitening images can illustrate a possible change, but the result depends on the type of stain, natural tooth colour, treatment protocol, restorations, and how the image was taken.
Which stains and restorations respond differently to bleaching?
Bleaching mainly affects some stains within natural enamel and dentine, while crowns, veneers, fillings, and bonding do not bleach in the same way. Online images may also differ in lighting, camera settings, dehydration, and editing.
What should you do before starting teeth whitening?
Have a dentist identify the stain and examine cavities, cracks, gum health, and existing restorations before whitening. Follow the prescribed material and contact time, and use sensitivity measures recommended for your teeth rather than copying an online routine.
When should whitening side effects be checked by a dentist?
Seek care if whitening causes persistent pain, gum burns, uneven colour, or sensitivity that does not settle. A dentist can distinguish surface stain, intrinsic discolouration, enamel defects, and restoration mismatch.
What shade change is realistic for your natural teeth?
Ask what type of discolouration you have and what shade change is realistic for your natural teeth. Ask whether restorations will need replacement for colour matching and how sensitivity will be managed.
