Dentist whitening trays before and after
Dentist-made whitening trays fit closely over your teeth and can create a gradual, more even colour change when used with prescribed gel.
The short answer
Dentist-made whitening trays are custom-fitted from impressions or a digital scan, and the before-and-after change is assessed against the original tooth shade. The tray holds peroxide gel against natural teeth while limiting contact with the gums.
What is the direct answer?
What does this question mean?
The starting photograph or shade record shows the baseline, while a later record shows the change after the prescribed course. Results vary with enamel colour, surface and internal stains, gel exposure, and restorations that do not bleach.
What can you do next?
The dentist examines the teeth and gums, records a shade, checks existing restorations, and makes the trays. Use the specified amount of gel for the specified wear period, clean the trays, and store them away from heat and pets.
When should you seek dental care?
Contact the dental team if the tray cuts the gum, gel repeatedly leaks onto the gum, or sensitivity interferes with eating. A review is also needed when the result is patchy, a tooth changes colour, or a filling no longer matches.
What should you ask the dentist?
Ask how the shade will be recorded, whether your restorations will match afterward, and how many applications are planned. Ask what to do if the tray feels loose or sensitivity occurs.
Frequently asked questions
Are dentist-made trays better than a shop-bought tray?
A custom tray is shaped to your teeth and can hold gel more precisely; the appropriate option depends on your mouth and the stain.
Why are the results uneven at first?
Uneven colour can reflect different stain depths, dehydration after treatment, tooth position, or restorations that do not whiten.
