Ever had a whitening case that just… stopped improving?
Or a patient panicking about white patches mid-treatment?
And what about those single discoloured teeth — do you really need to drill an access cavity for internal bleaching?
In this second-part episode, we are joined once again by Dr. Wyman Chan – yes, the legend who hung up his drill to dedicate his career entirely to whitening. This time, we dive into real-life cases: everything from “wedding-ready” makeovers to stubborn MIH spots, and those frustrating single discoloured teeth.
Wyman reveals his secret sauce for whiter, healthier smiles, and why trays aren’t the only way forward.
We also get honest about patchy results and blotchy teeth mid-treatment – why they happen, how to talk patients through them.
Key takeaways:
- Alkaline gels encourage natural remineralization by using calcium and phosphate from saliva.
- White patches during whitening are common and usually fade with continued use.
- Clear communication and consent help prevent panic over blotchy results.
- MAGIC 3 can speed up blending of white spots.
- ICON resin infiltration doesn’t always work for deep lesions; sometimes minimal enamel removal and composite are better.
- If shade changes plateau, try switching to a different whitening gel.
- Photos with shade tabs are essential evidence and boost patient trust.
- External whitening can treat single discoloured teeth, but it’s slower than internal bleaching.
- Patient expectations are the biggest factor in whether a case feels like success or failure.

AGD Subject Code: 780 – Esthetics/Cosmetic Dentistry
Aim: To explore practical approaches to teeth whitening, from handling caries and white spot lesions to using trayless, alkaline systems that promote natural remineralization. It also aims to give dentists clear strategies for patient communication, case selection, and choosing when to stick with simple, reliable techniques.
Dentists will be able to:
- Explain the role of pH and alkalinity in whitening systems and their effect on enamel remineralization.
- Compare tray-based and trayless whitening protocols, including patient compliance factors and clinical outcomes.
- Apply strategies for effective patient communication and consent, particularly around expected outcomes like patchiness and shade progression.
