This guide is general education, not a diagnosis or an individual treatment plan. Urgent, severe or worsening symptoms belong with the local emergency service or a qualified clinician.
What this guide covers
Tooth colour, stains and whitening evidence. This source-reviewed orientation page separates stable record-the-exact-site-duration-pattern-trigger-exposure-and-change-over-time principles from decisions that depend on examination, probing, imaging, saliva function, medical and medicine history, restoration status, tooth-wear distribution, product concentration, age, local law and an individual dental or medical assessment. The named editions, URLs and reuse limits were checked on 2026-09-10.
It remains outside search indexes pending a second-person clinical editorial review and localisation.
How to use it
Start with the description that most closely matches your question about Tooth colour, stains and whitening evidence. Use the evidence section to understand what is known, then use the boundary section to decide when self-education should stop and clinical care should begin.
The page keeps the main question, its evidence base and its limits together in one canonical place. That makes it useful as a quick orientation and avoids splitting a broad subject into shallow pages before each narrower answer has enough verified material of its own.
Reviewed editorial notes
These concise notes are independently written from the source set below. In an emergency, use the local emergency number and follow the dispatcher rather than relying on a static page.
Separate surface stain, internal discoloration and restoration colour
Record whether one tooth or many changed, timing, recent trauma or dental work, pain, surface deposits, tobacco and strongly pigmented foods or drinks, and existing fillings, crowns, veneers or implants. ADA material distinguishes extrinsic from intrinsic discoloration and notes that tooth-coloured restorations do not whiten like natural teeth. A screen photo cannot establish shade, vitality, decay, pulpal disease or the cause of a single dark tooth.
Check oral health, peroxide scope and local law before whitening
EU Directive 2011/84/EU sets concentration- and age-related conditions for tooth-whitening products that release hydrogen peroxide and places some use under dental-professional examination and supervision; current national implementation controls. ADA evidence notes temporary sensitivity and gingival irritation as common adverse effects and limited evidence for some do-it-yourself approaches. TempoLife does not approve a product, concentration, duration, provider or home mixture and never treats whitening as care for unexplained pain or discoloration.
