In-Office Teeth Whitening in Los Angeles
Up to eight shades, in a little over an hour.
The difference between professional whitening and a supermarket kit is not effort, it is depth — a light-activated gel reaches the stain rather than the surface. Smile LA Downtown Modern Dentistry uses Zoom, and you walk out with the result the same day.
The session
How a Zoom session works
A team member applies the Zoom Whitening Gel to your teeth, then activates it with a low-heat Zoom Light. That lets the whitening agent pass through the enamel and into the dentin beneath, lifting stains that sit below the surface rather than polishing the surface itself — which is the actual difference between professional whitening and a kit off a shelf. It is depth, not effort. The whole appointment takes about 45 minutes to an hour, and most patients see six to eight shades of improvement in that one sitting. You are supervised throughout, which is what allows a stronger agent to be used than anything you could safely apply to yourself at home.
Why in the chair
Why in-office rather than at home
- Speed A noticeably brighter smile in one visit, rather than weeks of nightly trays.
- Effectiveness More effective than over-the-counter options at lifting deep stains, with longer-lasting and more consistent results.
- Safety Carried out under the supervision of a licensed cosmetic dentist and monitored throughout.
The trade-off is that it happens on our schedule rather than yours. Where that is the problem, take-home whitening reaches a similar place more slowly.
The first 24 hours
Avoid dark-colored foods and drinks for the first day, or you undo some of the work. Some patients experience temporary sensitivity, which typically subsides within a few days — a desensitizing toothpaste and avoiding very hot or cold food helps it along.
What it will not lift
Whitening works on natural teeth only, so existing crowns and veneers keep their original shade and we will plan around that. Zoom is most effective on stains from food, drink and aging, and can be less effective on discoloration caused by medication. See teeth whitening for why teeth discolor in the first place.
The short answer
In-office teeth whitening is a professional treatment in which a whitening gel is applied to the teeth and activated with a low-heat light, lifting stains from the enamel and the dentin beneath. A Zoom session takes about 45 minutes to an hour and is carried out under the supervision of a licensed cosmetic dentist. Most patients see six to eight shades of improvement in that one sitting, and it works on natural teeth only, not on existing crowns or veneers.
In-Office Whitening FAQ
- How long does it take?
- A Zoom session takes about 45 minutes to an hour, in a single visit. During that time the whitening gel is applied and activated with a low-heat light, and you are supervised throughout. You walk out with the result the same day, rather than working toward it over weeks of nightly trays.
- How much whiter will my teeth be?
- Most patients see six to eight shades of improvement, depending on how stained the teeth were to begin with. Zoom is most effective on stains from food, drink and aging. It can be less effective on discoloration caused by medication, and it does not change the shade of existing crowns or veneers.
- Will it make my teeth sensitive?
- Some patients experience temporary sensitivity, which typically subsides within a few days. A desensitizing toothpaste helps it along, as does avoiding very hot or cold food. The session itself is supervised and monitored throughout.
- Can I eat straight afterwards?
- Avoid dark-colored foods and drinks for the first 24 hours after a session. Having them during that first day can undo some of the work. If you notice temporary sensitivity, avoiding very hot or cold food also helps.
- How often can I have it done?
- Most patients do not need to repeat it for at least 6 to 12 months. The interval depends on how stained the teeth were to begin with and on how much staining food and drink they meet afterward. Avoiding dark-colored foods and drinks for the first 24 hours is the first step in keeping the result.
- What about my crowns and veneers?
- Whitening only works on natural teeth, so existing crowns and veneers keep their original shade. Where you have restorations, the plan works around that so the result looks even across the whole smile. That conversation happens before the session, not after it.
