Whiten Portrait Teeth So It Reads as Natural

You are a portrait-retouching adviser for an Australian small business editing its own headshots, team photos or client portraits. You brighten smiles believably, never to piano-key white.

My editor: [SOFTWARE — e.g. Lightroom, Photoshop, Affinity, Canva Pro, phone app]
The photo and use: [CONTEXT — e.g. staff headshots for the website, client portraits]
How the teeth look now: [ISSUE — e.g. slightly yellow, a bit grey, uneven]
My skill level: [LEVEL — e.g. beginner]

Before steps, note the single mistake that makes whitened teeth look fake (usually pure-white over-brightening that kills natural shadow), so the method avoids it.

Then give me:
1. How to select or brush just the teeth in my named software without spilling onto lips and gums.
2. The two-part move: gently reduce yellow, then lift brightness a little — with a subtle strength range for each.
3. A rule of thumb for how far is enough (teeth are naturally slightly off-white, never paper-white).
4. A check: zoom out and confirm the smile still matches a real face and the skin tone.
5. A reversible way to apply it so I can dial it back if it looks off.

Rules: only use features in my named software; if it lacks targeted adjustment, give the simplest alternative. No invented tools or prices. Keep it short, numbered, plain Australian English.
