Dental Questions: Will my teeth be whiter after a dental cleaning?

Have you ever had your teeth cleaned only to see no noticeable difference in their appearance? Your mouth may feel cleaner, but the shade of your dental enamel probably didn't change too much. Read on to find out why this is the case, and what a routine cleaning actually achieves!

For the majority of the population, yellow and discolored teeth are caused by something called intrinsic staining. Here, the teeth pick up pigment in the dentin layer beneath the outer enamel. No amount of brushing, scrubbing or abrasive products will remove these compounds. A smaller portion of the population will be effected by extrinsic staining. This occurs when a combination of deeply colored foods, plaque and tartar discolor the surface of the teeth. This staining most commonly effects smokers, heavy coffee drinkers and those with deficiencies in their daily oral care. Because this staining only involves the outermost layer of the teeth, brushing and flossing will have some control over its presence.

As you can probably see, dental cleanings will have little to no affect on intrinsic staining. To take care of dentin layer staining, you will need to use a specific bleaching system like white strips, bleach trays or ZOOM whitening. However, extrinsic staining will be readily addressed by a routine "prophy" cleaning. Since these stains are adhered to the surface of the teeth, mechanical polishing and scaling will eliminate them with ease. 

Your routine cleaning serves three general purposes: to remove plaque and tartar from the teeth, allow a dental professional to asses changes in your oral health, and provide feedback on your home care between visits. The combined goal of these objectives is to protect the teeth from periodontal disease and the progression of tooth decay. Any improvements in the cosmetic appearance of the teeth after a cleaning is a celebrated secondary benefit.

Is bleaching safe for your teeth?

Every year, millions of patients worldwide bleach their teeth using various products. Whether prescribed by a dentist or purchased over-the-counter, almost every effective whitening method utilizes some type of peroxide gel. When used correctly, they are all safe and effective ways to lighten the color of your teeth. Read on to catch the full story!

Peroxides (hydrogen peroxide, carbamide peroxide, etc.) whiten teeth by breaking down the pigmented compounds in the tooth's dentin layer (between the enamel and pulp). To reach this space, these products rely on opening up small gaps in the dentin called microtubules. This can cause a temporary sensitivity to air and cold liquids. However, the tubules quickly re-mineralize and close in a matter of hours. For cases of extreme sensitivity, we may recommend extra fluoride applications to dull the ache. 

Research shows that whitening causes no long term negative effects on teeth. However, prescription strength whitening procedures (zoom whitening or custom bleach trays) have the potential to irritate or discolor the gum tissue. This is why it is important to follow the dentist's directions carefully. It is also important to note that over whitening can cause the teeth to have a blue tint that many patients find undesirable. 

When performed correctly, whitening is an easy and convenient way to improve the cosmetics of your smile. If you would like to discuss your tooth whitening options, please give our office a call!

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!

Types of Dental Whitening

Tooth whitening provides a quick and dramatic improvement to your overall smile. If you've done some research, you have probably found out that there are a number of products and services on the market today. Here is a quick guide to help you pick the best type of whitening for your specific needs!

Home whitening kits- All whitening products that work utilize some form of hydrogen peroxide. The main difference between an over-the-counter solution and something administered by a dental professional is the concentration of peroxide. Products like Crest Whitestrips will give you similar results to in-office whitening, but over a much longer time frame. Given you needs and expectations, this could be the perfect solution!

Whitening trays- These trays are made from a clear material like Invisalign retainers and are custom molded to your teeth. Since they prevent the peroxide from contacting your gums and cheeks, a higher concentration can be used. They are typically used once a day for two weeks, followed by one day a month for maintenance. 

In-office "Zoom" whitening- Here, whitening solutions are directly applied to the teeth under the supervision of a dental professional. The gums are blocked out using a special material and a very high concentration of peroxide is carefully applied to the teeth. The results are instantly noticeable and long lasting. This method achieves the same results as weeks of OTC whitening in about an hour and a half. 

"Mall Whitening" Kiosks- These stands (usually found in shopping malls) offer whitening services for rates somewhere in between home whitening kits and professional in-office whitening. However, the employees operating these stands are not dental professionals and generally cannot offer any products stronger than what you can buy over the counter. Your money is better spent either with a Whitestrip-type product or in an actual dental office. 

Whitening toothpastes, mouthwashes, floss, etc.- Just about every dental product nowadays advertises some sort of whitening ability. However, don't expect to see huge benefits. They are mostly aimed at surface staining, rather than the deep discolorations that cause yellow/ dark teeth. To get vibrant white teeth, you need to seek out a product that contains hydrogen peroxide. 

Natural whitening remedies- In general, whitening products that don't contain hydrogen peroxide (or some form of peroxide) won't really show any benefits. There are a number of instructions online, involving everything from strawberries to oil pulling, but it is unlikely that any of them will actually work. If you're looking to maintain a whiter smile naturally, cut back on pigmented liquids and drink with a straw when possible.

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.
