How to use lanbena teeth whitening
Use a whitening product only as its label directs, keeping gel off the gums and checking for dental disease first.
The short answer
Use a whitening product only as its label directs, keeping gel off the gums and checking for dental disease first. Product strength, tray design, contact time, and ingredients determine how it should be applied.
What is the direct answer?
What does this question mean?
Home whitening uses a peroxide compound to oxidise some stain molecules within natural enamel. It cannot recolour fillings, crowns, veneers, or other tooth-coloured restorations.
What can you do next?
Read the complete label, inspect the applicator or tray, and use only the stated amount on clean, dry teeth. Remove excess from the gums, rinse after the instructed contact time, and stop for strong sensitivity or burning.
When should you seek dental care?
Get a dental examination before whitening if you have cavities, cracks, gum inflammation, exposed roots, or unexplained tooth pain. Seek advice when pain or soft-tissue irritation remains after the product is removed.
What should you ask the dentist?
Ask whether the ingredient list and application method suit your teeth, gums, restorations, and sensitivity history. Ask whether a custom tray or a different whitening plan would control where the gel contacts.
Frequently asked questions
Can I leave the product on longer?
No. Use only the labelled contact time or the schedule prescribed for you.
Why are my teeth sensitive after whitening?
Peroxide can temporarily irritate the tooth nerve through enamel and dentine; persistent pain needs review.
