A whitening advertisement cannot show whether its promised result is realistic for your teeth. Start by asking what is causing the color change and whether the proposed method fits your mouth.
Natural teeth and restorations differ
Whitening does not change the color of crowns, veneers or fillings, and different kinds of discoloration do not respond equally. If you have visible restorations, discuss possible color differences before buying treatment.
Some people develop sensitivity during whitening. Overusing products can harm teeth or gums, so follow the instructions rather than trying to accelerate the result or combine several products.
Compare the actual plan
- Is the recommendation stain removal, home whitening or office treatment?
- Which teeth or restorations are unlikely to change?
- What should I do if sensitivity occurs?
- How often and for how long should the product be used?
- What review or follow-up is included?
Keep expectations practical
Bring the name of any product you already use. Ask the dentist to explain likely limitations and how the result will be assessed. If you are planning for an event, allow time for an individual assessment rather than relying on a last-minute promise. A clear application schedule and realistic expectations are more useful than an exact shade promised to everyone.
