What carbamide peroxide strength might your whitening plan use?
Dentists choose carbamide peroxide strength and wear time based on the tray, stain, sensitivity, enamel, and treatment plan.
How does carbamide peroxide work during teeth whitening?
Carbamide peroxide is a whitening ingredient that decomposes into urea and hydrogen peroxide. The released peroxide diffuses through tooth structure and reacts with stain molecules.
How should you use the whitening concentration supplied to you?
Use only the concentration and schedule supplied for your specific tray or product. Keep gel on the tooth surfaces, avoid gum contact, and report sensitivity instead of extending wear time yourself.
When should tooth pain or gum burning stop you whitening?
Seek an examination before whitening if teeth are painful, cracked, decayed, or discolored from trauma, and stop if gums become sore or burned.
What whitening strength and wear time suit your teeth?
Ask which strength suits your teeth, how long each application should remain in place, and how fillings, crowns, or veneers will affect the result.
Frequently asked questions
Why is a stronger gel not always better?
More concentrated exposure can increase sensitivity or gum irritation, while the appropriate choice depends on the diagnosis and tray protocol.
Will it whiten a crown?
No. A crown keeps its material color, so its shade should be considered before natural teeth are whitened.
