Find out what is causing the colour concern

Natural tooth colour varies, and discolouration can have different causes. A professional assessment can distinguish a cosmetic concern from something needing investigation and check the health of the teeth and gums. A darker tooth should not automatically be treated as a simple whitening problem.

Describe what you want to change without starting from a product name. Existing fillings, crowns or veneers may not lighten in the same way as natural teeth, so they need to be part of the discussion. A uniform result cannot be promised from a photograph or a shade sample.

Understand the process and its limits

Ask who supervises the treatment, how it is used and what to do about sensitivity or irritation. Different approaches have different instructions, and the real provider should explain suitability and relevant restrictions. Do not assume that a stronger or faster approach is appropriate.

Avoid household substances or improvised methods. Marketing language about a new technology is not evidence that it is suitable for your mouth or free of risk. Stillwell names no commercial system and makes no promise of a particular shade, speed or lasting result.

Compare the continuing commitment

Ask how colour can change over time, whether maintenance is likely and what happens if restorations no longer match. The initial treatment and any later work should be distinguished in an estimate. You can also choose to leave the colour unchanged.
