Question and answer

Is at home teeth whitening safe

Home whitening risks depend on gel chemistry, concentration, contact time, tray fit, and the condition of your teeth and gums.

The short answer

Home whitening risks depend on gel chemistry, concentration, contact time, tray fit, and the condition of your teeth and gums. Peroxide can irritate gingiva and penetrate enamel toward dentine, producing sensitivity. Poorly fitting trays can pool gel against soft tissue, and whitening cannot correct decay, gum disease, or restoration colour.

What is the direct answer?

What does this question mean?

Peroxide can irritate gingiva and penetrate enamel toward dentine, producing sensitivity. Poorly fitting trays can pool gel against soft tissue, and whitening cannot correct decay, gum disease, or restoration colour.

What can you do next?

Have a dentist inspect your mouth and explain the product before starting. Use the recommended quantity, avoid combining products, protect the gums from excess gel, and stop when symptoms persist.

When should you seek dental care?

Arrange care for persistent sensitivity, gum ulcers, bleeding, decay symptoms, or an uneven dark tooth. Swelling, fever, or severe pain needs prompt assessment.

What should you ask the dentist?

Ask how the product is used, what symptoms mean stop, and whether a custom tray or another treatment is more suitable.
