Dental Questions: Do whitening strips work?

Tooth whitening is the most commonly requested cosmetic procedure at dental offices nation wide. Lightening the shade of dental enamel can create a dramatic change that draws attention to your smile. As such, you have probably seen products like Crest WhiteStrips at your local pharmacy and wondered if they were worth the investment. Why would someone choose these over a professional bleaching treatment performed at a dental office? For these answers and more, read on!

Any tooth whitening product that works (from a scientific perspective) will have some concentration of a peroxide compound. Peroxide works by oxidizing the pigments that have leached into your teeth and removing their colors. Typically, dental products contain either carbamide peroxide or hydrogen peroxide suspended in some type of gel. 

The main difference between a whitening strip, a bleach tray and an in-office bleaching session is the concentration of peroxide. Since these compounds are slightly caustic, high levels of peroxide can cause gum irritation or discoloration. For an in-office whitening session, the gums can be safely guarded and isolated, allowing us to use a higher level of peroxide. As a result, you will see an almost instantaneous change in the shade of your dental enamel. With a product like WhiteStrips, the plastic tray is not custom molded to your teeth and is bound to contact your gums or become leaky out the sides. Hence, a lower concentration of peroxide must be used, with noticeable results taking longer to appear. 

Which type of whitening is best? That can only be answered on a patient-by-patient basis. For those looking for a cost effective change without a deadline, over-the-counter whitening strips are a great option. If you're looking for a single treatment that brings almost instant results, in-office bleaching might be better. It really depends on what you hope to accomplish and how much time you can devote to your treatment.

What type of whitening is right for me?

In previous posts, we've discussed the many different tooth whitening products available on the market today. With all the choices, picking one that works for you can be a difficult task. In this article, we will categorize the many methods based on what they do best. Each type has unique advantages and disadvantages, so take a look!

Fastest method: In-office whitening. Products like Phillips Zoom are professionally administered and provide dramatic results in a single visit. A typical appointment is about 80 minutes and matches the results of months of over-the-counter bleaching. 

Cheapest method: Crest Whitestrips and similar products. Over-the-counter bleaching methods will whiten your teeth for the least amount of money. However, they work quite slowly. Expect to use them for weeks/months before you notice a difference. 

Most flexible method: Professional bleach trays. The trays are worn for one hour once a day for two weeks, followed by one day a month for maintenance. You will see fast results and be able to adapt to your own schedule. 

For patients susceptible to "whitening pain:" Professional bleach trays with 10% bleach. Whitening products cause pain because they contain an agent that opens tubules in the tooth to let the bleach in. In some cases the open tubules can cause sensitivity or a sharp "zinging" pain. For these patients, we prescribe a milder bleach along with a fluoride rinse that counteracts sensitivity. This combination seems to be gentle enough for even the most sensitive mouths!

For patients who "just want whiter teeth:" All of the above! Any of these methods will get you to a whiter smile. It's up to you to pick the best product for your specific needs. If you have any further questions, feel free to give us a call!

Dental Questions: What's the difference between Zoom whitening and bleach trays?

You have probably heard of two main types of bleaching systems offered at dental offices: "ZOOM" whitening and bleach trays. While they both achieve the same results, there are some differences between the two procedures that you should take note of:

ZOOM Whitening is the name brand for Phillip's in-office bleaching system. Here, the entire "whitening" procedure is performed in our exam rooms. We use a blocking material to shield your gums and apply several layers of concentrated peroxide gel to your teeth. A special light is utilized to speed up the chemical reaction by activating the gel. Overall, ZOOM takes about an hour and twenty minutes from being seated in a chair to leaving our office. In the meantime, you will be set up with Pandora music, cable TV or Netflix movies. While this is the fastest way to whiter teeth, it is also the most likely to cause temporary sensitivity issues afterwards. 

Bleach Trays are a home whitening system that is administered and monitored by a dentist. You will need an initial appointment for a consultation and impressions of your teeth. Later that day or the following day, your new bleach trays will be ready. You then perform the actual "whitening" at home using a peroxide gel (similar to ZOOM, but lower in concentration). Typically, patients are instructed to whiten for one hour once a day for 14 days, followed by once a month as needed. This type of whitening does work slower, but usually causes less sensitivity issues and can be adjusted to your personal comfort level. 

Overall, you can see the similarities and differences between ZOOM and bleach trays. Some of our patients even combine the two procedures- that is, have one ZOOM session and bleach trays made for maintenance (done in the same visit). Since both services rely on the same peroxide gel, they can be used together for additive action. If you have any further questions on bleaching, bleach trays or other cosmetic procedures, please give our office a call!

Zoom In Office Whitening

At Thousand Oaks Family Dentistry, we pride ourselves in staying at the forefront of dental technology. Every time a product is release, redesigned or improved, we take care to review its merits and how it can benefit our patients. Sometimes, products need further research and development before they are ready for our office. Others show great promise in improving results, comfort or efficiency.

    One of the most recent additions to our office is the latest Philips Zoom Whitening light and bleach system. While we have offered in-office whitening for many years, this update brings us to the forefront of bleaching speed and results. We are highly impressed with the research results and clinical data from this system and are proud to offer it to our patients.

    Almost every bleaching system works via some form of hydrogen peroxide, and Zoom whitening is no different. However, this system combines a specific concentration of peroxide with a highly specialized activation light. This light aids in the bleaching process by adding mild heat and energy to the peroxide oxidation reaction.

Essentially, bleaching works by allowing peroxide penetrate deep into the tooth dentin and degrade the compounds that cause staining. The Zoom lamp enhances this process by making the peroxide more viscous and speeding up the oxidation reaction rate. The end result is whiter teeth in a shorter amount of time, versus bleaching sans light.

Zoom appointments typically take about 75 minutes from checking in to leaving our office. We start by seating you and getting you set up with TV/Netflix/music. Once you are comfortable, we use a special blocking material to shield your gums from any stray bleach solution. This step is crucial, as the ultra concentrated bleach can easily discolor and irritate soft tissue. After we have your teeth isolated, we start the actual Zoom treatment. Your teeth are “painted” with the bleach formula and the light is focused at your mouth. The actual bleaching time is split into three 15 minute sessions. After your third session, we take out the gum shielding, rinse the bleach, and send you out with your brand new smile!

Many patients are concerned about the potential sensitivity associated with in office bleaching. This pain arises from microtubules within the teeth opening, which allows the peroxide to penetrate deep into the tooth. Unfortunately, these open tubules also allow sensitivity to air, cold temperature and even the bleach solution itself. Without prior whitening experience, it is difficult to predict how you will personally respond to Zoom bleaching. However, we have great methods and procedures for minimizing any discomfort you may feel.

In short, Zoom whitening provides beautiful and long lasting results in a single office visit. If you are interested in this service, or any of our other cosmetic procedures, please schedule an appointment with our office.
