Name one advantage of professional whitening compared with OTC products.
A dental professional can evaluate oral health, customize treatment, and monitor for side effects.
A patient has exposed root surfaces and wants to whiten their teeth. What concern should you discuss?
Exposed roots may be more sensitive, and root surfaces may not respond to whitening like enamel does.
What is a common side effect of OTC whitening products?
Tooth sensitivity or gum irritation
Should a patient scrub back and forth aggressively with an electric toothbrush?
No. They should guide the brush slowly along each tooth and the gumline, following the manufacturer's instructions.
Why should a patient with gingival recession be careful about brushing pressure?
Excessive pressure can contribute to further abrasion and may worsen existing tissue damage.
Why should a patient have a dental examination before professional whitening?
To identify cavities, gum disease, restorations, or other issues that could affect safety and results
A patient uses a hard-bristled brush and has cervical abrasion. What is your recommendation?
Switch to a soft-bristled brush, use gentle pressure, and review brushing technique.
What are the main bleaching ingredients found in many OTC whitening strips?
Hydrogen peroxide and carbamide peroxide.

Approximately 45 degrees.
A patient wants professional whitening but has severe tooth sensitivity. What should the dental professional do first?
Evaluate the cause of the sensitivity and determine whether whitening is appropriate before starting treatment.
A patient says their whitening strips have not worked on a dark front tooth after an injury. What should you recommend?
A dental evaluation to determine the cause of discoloration before choosing treatment.
A patient uses whitening strips but has crowns on their front teeth. Will the crowns whiten along with their natural teeth?
No, whitening products do not change the color of crowns, veneers, or fillings.
Is an expensive electric toothbrush automatically better for every patient?
No. Technique, consistency, individual needs, and proper use matter more than price alone.
A patient brushes twice daily but still has plaque along the gumline. What should the hygienist assess first?
Brushing technique, brush positioning, pressure, and whether all tooth surfaces are being cleaned effectively
Why might brown or gray discoloration not respond as predictably to whitening?
The cause of discoloration matters; some intrinsic stains, such as those from certain medications or tooth injury, are more difficult to treat.
A patient has gum disease and wants to focus on whitening. What is the priority?
Address the gum disease and establish oral health before considering whitening.
