Question 3

A patient with known sensitivity should use a tray for how long per session when starting at-home whitening?

Accepted Answer

Start with shorter sessions (e.g., 30–60 minutes) and gradually increase

Answer

For sensitive patients, starting with shorter wear times allows the teeth to acclimate and reduces the risk of significant sensitivity or pulp irritation.

In-office power bleaching with 35–40% hydrogen peroxide

Answer

In-office power bleaching using high-concentration hydrogen peroxide (35–40%) delivers the most dramatic whitening in a single appointment.

Question 5

Why should whitening treatment be postponed for patients with untreated cavities?

Accepted Answer

The bleaching gel can penetrate decay and cause severe pulp pain or damage

Answer

Bleaching gel can seep into cavities and reach the pulp, causing intense pain or irreversible pulp damage if decay is present.
