Philips Zoom whitening in Santiago

Philips Zoom WhiteSpeed is the in-office whitening system we use in Vitacura: a professional-concentration hydrogen peroxide gel activated by an LED lamp that accelerates its action. It all happens in a single session, with the gums isolated by a precision barrier and the gel applied only on enamel. We brought it into our Vitacura clinic after the team evaluated the results in practice.

It is worth being clear about what the lamp contributes and what it does not. The LED accelerates the peroxide reaction and lets the treatment be concentrated into one session, which is its real advantage. What defines the final result is the complete protocol: what kind of discoloration you have, how the tooth was prepared beforehand, how sensitivity was controlled, and what you do in the following weeks with what you eat and drink. A device replaces none of those steps.

That is why Zoom at AS Odontología Digital is not booked without an evaluation. The first visit is exactly that: intraoral photography, Vita shade recording and sensitivity assessment. Before whitening we do an Airflow GBT prophylaxis to remove biofilm and surface staining, because whitening over accumulated pigment gives an uneven result. Only then comes the in-office session.

With Zoom the treatment ends in that session: it does not require an at-home phase. Studies comparing protocols show that adding trays to the in-office session does not improve the final color, so we do not add them out of habit. What we do is a check-up at two weeks, once the color has stabilized, to evaluate the result and decide whether a top-up is needed.

When the evaluation shows that a more gradual pace suits you, because of prior sensitivity or the type of staining, we recommend our combined protocol instead: an in-office session with peroxide under isolation, without a lamp, plus individualized 3D-printed trays with carbamide peroxide take-home gel. Carbamide peroxide breaks down slowly into hydrogen peroxide and urea, which is why it acts more gently and over a longer period. It is worth saying plainly: the higher concentration does not deliver a better final result. Clinical trials comparing take-home concentrations find no relevant difference in final color or in sensitivity. What changes is the pace and individual tolerance.

Sensitivity is the most frequent adverse effect and we prefer to discuss it beforehand. Clinical-concentration peroxide can cause transient discomfort in the following hours, more often in patients with gingival recession or abfractions. We manage it with preventive desensitizers before the session, controlled application time and, in the combined protocol, adjustment of the home schedule. It is transient and does not damage enamel, but if you have a history of marked sensitivity it is worth saying so at the evaluation so we can adapt the protocol.

Whitening lightens the natural tooth. It does not change the color of veneers, crowns or composites, which keep their original shade and can end up visibly different if this is not planned for. So when aesthetic restorations are part of the plan, the correct order is to whiten first, wait for the color to stabilize, and only then define the shade of the veneers or smile design. Doing it the other way around means redoing work that was already well done.
