What is the direct answer?
Lanbena whitening products use a peroxide gel to lighten stains on enamel; follow the package directions and stop if your gums or teeth react.
What does this question mean?
Lanbena kits may include gel, a tray, strips, or a light device, and instructions differ by product.
What can you do next?
Use only the supplied tray or strip as directed, keep gel off the gums, and do not combine whitening chemicals.
When should you seek dental care?
See a dentist before use if you have cavities, cracked teeth, gum disease, exposed roots, or restorations.
What should you ask the dentist?
Ask which active ingredient the kit contains, whether restorations will change color, and how to manage sensitivity.
Frequently asked questions
Can home care replace a dental examination?
No. Home care can reduce irritation while the cause is assessed, but it cannot diagnose or repair dental disease.
What symptom should not wait?
Facial swelling, fever, severe worsening pain, or difficulty swallowing or breathing needs prompt dental or emergency care.
