Professional teeth whitening in Beirut, in one visit or at your own pace.
In-office whitening at Lumident takes a single appointment of about 60 to 90 minutes. Guided take-home whitening works over one to two weeks and suits anyone with sensitive teeth, because the concentration is lower and you control the pace. Both are supervised by the dentist, which is the difference between whitening and the pharmacy strips.
What happens at a whitening appointment?
Whitening is quick, but it is worth doing in the right order. Cleaning first, then shade matching, then the treatment itself.
1 visit
Check and clean first
Whitening lifts stain from enamel, so any decay or gum inflammation is treated first and the teeth are professionally cleaned. Whitening over plaque gives an uneven result.
Same appointment
Shade record
Your starting shade is recorded against a reference guide, so the change at the end is something you can see rather than something you have to take on trust.
60 to 90 minutes
In-office whitening
The gums are isolated and a professional-strength gel is applied in timed cycles. You sit through it in one appointment and leave with the result.
1 to 2 weeks
Or guided take-home
Custom trays are made from impressions of your teeth, with dentist-prescribed gel and instructions. Gentler on sensitive teeth, and easy to top up later.
What whitening will not do
Whitening works on natural enamel and nothing else. Crowns, veneers, and white fillings keep the shade they were made in, so if you have visible restorations at the front, whitening the teeth around them can leave a mismatch and the honest answer is to plan the restorations and the whitening together. Grey discoloration from old root canal treatment or from tetracycline responds far less predictably than the yellowing that comes from coffee, tea, and time. Sensitivity during treatment is common and settles within a day or two. Results are not permanent either: they last longer if the habits that stained the teeth in the first place ease off.
Who does this at Lumident
The Adults & Cosmetics department
Restorative & Cosmetic Dentistry
Whitening is prescribed by the adults and cosmetics department after an examination, rather than sold off a shelf. That is the difference that decides whether the result is even, whether your existing fillings and crowns still match afterwards, and whether sensitive teeth are handled properly.

Questions patients ask about whitening
Short answers first; anything specific to your teeth comes from a consultation.
How long does professional teeth whitening take?
In-office whitening takes one appointment of about 60 to 90 minutes. Guided take-home whitening with custom trays works over one to two weeks and is gentler on sensitive teeth.
How long do teeth whitening results last?
Typically one to three years, depending on how much coffee, tea, red wine, and tobacco the teeth meet afterwards. Take-home trays make topping up straightforward without repeating the full treatment.
Does whitening damage enamel?
Professionally supervised whitening uses controlled concentrations applied for timed cycles with the gums isolated, and does not thin or soften enamel. Temporary sensitivity during and just after treatment is common and settles within a day or two.
Will whitening work on crowns, veneers, or fillings?
No. Whitening only changes natural enamel, so existing restorations keep the shade they were made in. If you have visible crowns or veneers at the front, the whitening and the restorations are planned together to avoid a mismatch.
In-office or take-home whitening: which is better?
In-office is faster and supervised throughout, which suits a deadline. Take-home is more gradual and easier on sensitive teeth, and leaves you with trays for future top-ups. Both are prescribed after an examination, not sold off a shelf.
Why does whitening not work the same for everyone?
Yellowing from food, drink, and age responds well. Grey discoloration from an old root canal or from tetracycline responds far less predictably, and in those cases veneers or bonding may be the more honest answer.
