Byte before and after teeth
Byte whitening before-and-after results depend on the starting stain, enamel, treatment plan, and whether restorations are present.
The short answer
Before-and-after whitening results depend on the original tooth color, the stain type, the whitening material and schedule, and whether visible teeth contain restorations. Photographs are useful only when lighting, angle, and shade comparison are consistent.
How does peroxide whitening alter surface stains?
At-home whitening uses peroxide to alter stain molecules in natural tooth structure. It does not lighten fillings, crowns, veneers, or bonding, so mismatched restoration color may become more noticeable.
How can you prepare for safer home whitening?
Have the teeth and gums checked before using a whitening kit, then follow the supplied wear schedule and keep trays clean. Record sensitivity and stop if gum irritation or pain develops.
When does uneven whitening need a dental examination?
Seek an examination for uneven color, a dark single tooth, decay, cracks, or sensitivity that continues after whitening. A dentist can distinguish stain from internal discoloration and plan treatment accordingly.
What should you ask about your tooth discolouration?
Ask what is causing the discoloration, whether whitening can affect your restorations, and which method suits your enamel and gums. Ask how photographs and shade records will be compared.
Frequently asked questions
Why did my teeth not whiten evenly?
Different stain depths, tooth anatomy, dehydration, or restorations can produce uneven color and require an examination.
Can whitening remove a gray tooth?
A gray tooth may have internal discoloration or pulp damage, which requires diagnosis rather than repeated surface whitening.
