When used as directed, teeth whitening products that contain hydrogen peroxide, like whitening strips, are carefully crafted to remove extrinsic and intrinsic stains safely. Extrinsic stains are caused by food, beverage and tobacco consumption over time; intrinsic stains are caused by tooth trauma, excessive fluoride, medications and aging.
With extensive research and clinical trials, Crest 3D Whitestrips are proven to be safe to use. The Whitestrips uses hydrogen peroxide to effectively whiten your teeth, the same key enamel-safe ingredient used by dentists.
Yes, you can use whitening toothpaste along with Crest 3D Whitestrips to help maintain a whiter smile. The combined amount of peroxide from whitening toothpastes and Crest 3D Whitestrips will not cause any harm.
Crest 3D Whitestrips are flexible, thin strips coated in a tooth whitener containing peroxide designed to securely conform to the shape of your teeth and keep the tooth whitener in place. The Whitestrips are guaranteed to whiten teeth by removing 10 years of tough, set-in stains.
The Crest Blue Light is backed by 15 years of advanced whitening technology, the same type of light technology used by dentists. It uses LED light to safely penetrate the surface of enamel to weaken tough stains, accelerating the whitening action of the hydrogen peroxide in Crest 3D Whitestrips for significantly whiter results.
Follow the Crest 3D Whitestrips usage instructions outlined on the package and then apply the Crest Blue Light for the last 10 minutes of wear time — five minutes for the upper strip, and five minutes for the bottom strip. The Crest Blue Light device will beep to notify you the lights have turned off in case you can't see it while in use.
The Crest Blue Light device beeps to notify you the lights have turned off in case you can't see it while in use.
The Crest Blue Light device is designed with built-in batteries that last the full number of treatments of your Crest 3D Whitestrips package. You do not have to replace the batteries and can discard the device after completing your last whitening treatment.
The Crest Blue Light device turns off after it has delivered sufficient LED light energy to the stains. It will last 10 minutes of wear time — five minutes for the upper strip, and five minutes for the bottom strip.
Crest 3D Whitestrips will not harm dental work including veneers, caps, fillings, partials, gold, composite bonding, laminates or any other restorations. However, they will also not whiten these types of dental work. The Whitestrips only work to whiten natural teeth, so if you have any dental work on any front teeth, you may see noticeable color differences between the whiter teeth and dental work when using this product.
Do not use if you have dental braces, and we recommend speaking to your dentist before using Crest 3D Whitestrips if you wear a retainer or have had a root canal. If you need any dental work, have dental work or are experiencing any staining from medication, we advise consulting your dentist to determine if using Whitestrips is appropriate.
We do not recommend using Crest 3D Whitestrips if you have an unfilled cavity or gum disease (periodontal disease). Check with your dentist before using any whitening product if you need dental work or treatment for periodontal disease.
We recommend waiting a few days after professional teeth cleaning to use Crest 3D Whitestrips in case your teeth and/or gums are sensitive to avoid further discomfort. We also suggest checking with your dentist before use.
We do not recommend using Crest 3D Whitestrips on your back teeth because the strips are specially designed to fit front teeth — the teeth shown when you smile. If you use Whitestrips on the back teeth, the strips may become loose and eventually fall off during the wear period as a result.
We do not recommend switching the upper and lower Crest 3D Whitestrips. Although the strips will work if switched, each strip is designed specifically to cover the specified area, and the shapes of the strips were also designed to keep them in place and cover the teeth exposed when you smile. If you wear the lower strip on your upper teeth, for example, the strip will cover less area.
We also do not recommend cutting the strip in smaller pieces to fit into different spots on your teeth. If a smaller piece dislodges, it has the potential to become aspirated or swallowed.
Teeth with tetracycline stains may not whiten as well as teeth with yellow stains since most dark or blue-gray teeth stains are caused by certain medication taken during tooth development and are deep within the tooth and the enamel surface. We recommend consulting your dentist if you have tetracycline stains.
No data is currently available on the effectiveness of Crest 3D Whitestrips on teeth with fluorosis stains. If you have this type of tooth stain, consult your dentist before use.
You may experience tooth sensitivity or gum irritation after using Crest 3D Whitestrips. Make sure to use the product as directed to limit chances of these occurring. If you do experience any tooth sensitivity, try Crest 3D Whitestrips Gentle Routine, which are carefully formulated to be gentle on teeth that may be sensitive to whitening.
If you notice white spots on your teeth after using Crest 3D Whitestrips, do not be alarmed. This is temporary and caused by the loss of water from the tooth enamel. Any water loss is not harmful and will go away on its own.
Yes, Crest 3D Whitestrips do not harm tooth enamel and are safe to use, so you can use one pack right after another. With that said, Crest 3D Whitestrips will whiten teeth for at least six to 12 months, so we recommend using Whitestrips twice per year to maintain a whiter smile. If you feel you are not seeing desired results, we suggest trying Crest 3D Whitestrips Professional Effects or consulting a dentist.
Although extensive consumer and clinical testing was done to establish the efficacy and safety of Crest 3D Whitestrips, we recommend following the usage instructions provided for each product. Longer wear time may cause tooth sensitivity and/or gum discomfort for some users.
You can brush your teeth gently immediately after using Whitestrips, but we do not recommend brushing your teeth immediately before applying Whitestrips, because this may irritate your gums. Make sure to allow enough time to pass if brushing your teeth prior to application to help avoid gum irritation.
Try applying Crest 3D Whitestrips by looking in a mirror and making sure each strip is in good contact with your teeth. If the Whitestrips start to slip, try closing your mouth and creating suction to tighten the strips on the surface. You can also try removing any excessive saliva from your front teeth with a clean paper towel before applying the strips. Avoid touching the Whitestrips excessively with your tongue; this may cause the strips to loosen. If you still are having trouble getting a strip to stick, try gently tucking it into the spaces between your teeth with your fingernail, then folding it behind the teeth.
Crest 3D Whitestrips are specially designed to strongly adhere to your teeth. If you experience any trouble removing a strip, try first peeling the strip off the back of your teeth to help loosen the grip; then, work your way to the front of the strip to peel the rest of the strip off your teeth.
If you feel any residue left on your teeth, do not worry. You can leave it since it isn’t harmful and should eventually dissolve; or you can gently brush it off, wipe it away with your finger or rinse your mouth out with water to remove.
Salvia will increase when any kind of object is placed in your mouth. As the saliva increases, it may react with the hydrogen peroxide in the Whitestrips and create a “foam.” This is a natural reaction and is not cause for concern.
The strip will not cause any adverse effects or damage if swallowed. It will simply pass through your system. However, swallowing large amounts of peroxide may cause stomach irritation or nausea. Consult a doctor if any irritation persists.
Crest 3D Whitestrips are not intended for use in children under the age of 12, and we have not conducted research on usage for this age group.
There is no evidence that Crest 3D Whitestrips is harmful to use when pregnant or nursing. However, we recommend consulting with your doctor before use.
Yes, storing Crest 3D Whitestrips in the bathroom, even with any steam or heat from the shower, should not affect the product.
You can store Crest 3D Whitestrips in the refrigerator, but we do not recommend storing this product in the freezer. If for some reason your Whitestrips become frozen, allow the product to warm to room temperature before use to ensure the Whitestrips work effectively.
Although they are still safe to use, we do not recommend using Crest 3D Whitestrips past their expiration date because the effectiveness of the whitening ingredient will be weakened.
Do not smoke while wearing Crest 3D Whitestrips. This can cause the strips to dislodge from your teeth and affect results.
Make sure to follow the usage instructions provided on the packaging for optimal results. If your teeth have significant discoloration, you may need to use two full boxes of Crest 3D Whitestrips to achieve the desired result.
