Teeth Whitening Patient Assessment & Candidacy 3

Question 1

What must informed consent for whitening treatment specifically ensure the patient understands?

Accepted Answer

Expected results, potential risks, treatment limitations, and available alternatives

Answer

Valid informed consent requires that the patient understands the anticipated outcomes, risks such as sensitivity, the limitations of whitening, and what alternative treatments exist.

Question 2

Which factor most commonly causes intrinsic tooth discoloration?

Accepted Answer

Systemic medications, dental trauma, or developmental disturbances during tooth formation

Answer

Intrinsic discoloration originates within the tooth structure and is most often caused by systemic medications like tetracycline, fluoride overexposure, trauma, or developmental anomalies.

Question 3

A patient with significant enamel erosion and tooth sensitivity from chronic acid reflux requests whitening. What is the most appropriate recommendation?

Accepted Answer

Delay whitening until the acid reflux is managed and sensitivity is adequately addressed

Answer

Acid erosion compromises enamel integrity and heightens sensitivity; whitening should be deferred until the underlying condition is controlled to avoid worsening damage and discomfort.

Question 4

During patient assessment, why is gum recession a specific concern before whitening?

Accepted Answer

Exposed root surfaces (cementum) are more sensitive and do not whiten the same way as enamel

Answer

Exposed cementum is more porous and sensitive than enamel and does not respond to whitening agents in the same way, often leading to increased sensitivity and uneven color results.

Question 5

How does a documented history of tooth sensitivity affect whitening treatment planning?

Accepted Answer

It guides selection of lower-concentration products and pre-treatment with desensitizing agents

Answer

A history of sensitivity leads clinicians to choose lower-concentration peroxide formulations and to pre-treat with desensitizing agents such as potassium nitrate or fluoride varnish.
