Bright now dental teeth whitening
A dental whitening service uses peroxide to reduce stains on natural teeth after the dentist checks enamel, gums, and existing restorations.
The short answer
A dental whitening service uses a peroxide preparation to lighten stains on natural teeth, with the method selected after checking enamel, gums, and restorations.
What does a named whitening service actually describe?
A named whitening service is a treatment category, not a diagnosis. The dentist first identifies whether the darker colour is on the surface or within dentin, because peroxide does not change every type of discoloration.
What usually happens during a whitening appointment?
The appointment normally includes a shade record, soft-tissue protection, controlled gel placement, and timed treatment intervals. A dentist may instead provide custom trays so the gel contacts the teeth evenly at home.
When does a change in tooth colour need examination?
Have a dental examination if colour change affects one tooth, follows an injury, or occurs with pain, a rough surface, a cavity, or bleeding gums. These signs can indicate a problem that whitening will not correct.
What should you ask about treatment and colour matching?
Ask how the stain was classified, which teeth will be treated, how the gums will be protected, and whether a filling or crown will need colour matching afterward.
Frequently asked questions
Is a lamp always needed?
No. Some systems use light or heat as part of the protocol, while others rely on the gel and a controlled wearing schedule.
Can whitening fix a cavity?
No. A cavity requires diagnosis and restorative treatment; whitening can make an untreated problem harder to assess.
