General Teeth Whitening
We formulate enamel safe teeth whitening treatments. We have confirmed the safety and efficacy of Crest 3DWhitestrips and Crest Whitening Emulsions in extensive clinical and technical testing. We recommend contacting your dental professional if you have additional questions regarding whether teeth whitening is right for you.
We do not recommend using Crest 3DWhitestrips or Crest Whitening Emulsions if you have an unfilled cavity or gum disease (periodontal disease). Check with your dentist before using any whitening products if you need dental work or treatment for periodontal disease.
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 3DWhitestrips or Crest Whitening Emulsions on teeth with fluorosis stains. If you have this type of tooth stain, consult your dentist before use.
Crest 3DWhitestrips: you can brush your teeth gently immediately after using Crest 3DWhitestrips, but we do not recommend brushing your teeth immediately before applying Crest 3DWhitestrips, 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.
Crest Whitening Emulsions is designed to work without rinsing or brushing off product after application.
There is no evidence that Crest 3DWhitestrips or Crest Whitening Emulsions are harmful to use when pregnant or nursing. However, we recommend consulting with your doctor before use.
Although they are still safe to use, we do not recommend using Crest 3DWhitestrips or Crest Whitening Emulsions past their expiration date because the effectiveness of the whitening ingredient will be weakened.
Please refer to the age information located on the outer packaging as the age varies by product. Crest Whitening Emulsions are recommended for ages 12 and up.
You can store Crest 3DWhitestrips and Crest Whitening Emulsions in the refrigerator, but we do not recommend storing these products in the freezer. If for some reason your 3DWhitestrips or Emulsions become frozen, allow the products to warm to room temperature before use to ensure they work effectively.
We recommend waiting a few days after professional teeth cleaning to use Crest 3DWhitestrips or Crest Whitening Emulsions in case your teeth and/or gums are sensitive to avoid further discomfort. We also suggest checking with your dentist before use.
Crest 3DWhitestrips and Crest Whitening Emulsions 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. Crest 3DWhitestrips and Crest Whitening Emulsions 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 3DWhitestrips or Crest Whitening Emulsions 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 Crest 3DWhitestrips or Crest Whitening Emulsions is appropriate.
Crest provides several products designed for people with sensitive teeth. If you experience regular or occasional teeth sensitivity during or after whitening, consider trying Crest Whitening Emulsions which is designed to give you 100% whiter teeth with virtually no sensitivity.
We have also designed Crest 3DWhitestrips Gentle Routine or Crest 3DWhitestrips Sensitive for people who may experience teeth sensitivity while whitening.
Yes, storing Crest 3DWhitestrips and Crest Whitening Emulsions in the bathroom, even with any steam or heat from the shower, should not affect the products. However, it’s best to avoid excessive heat.
The Crest 3DWhitestrip 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.
For Crest Whitening Emulsions: We have confirmed the safety and efficacy of Crest Whitening Emulsions in extensive clinical and technical testing. All ingredients in the formula are safe for consumption.
With extensive research and clinical trials, Crest 3DWhitestrips 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.
Crest 3DWhitestrips 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.
We do not recommend using Crest 3DWhitestrips 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.
Yes, you can use whitening toothpaste along with Crest 3DWhitestrips to help maintain a whiter smile. The combined amount of peroxide from whitening toothpastes and Crest 3DWhitestrips will not cause any harm.
We do not recommend switching the upper and lower Crest 3DWhitestrips. 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.
You may experience tooth sensitivity or gum irritation after using Crest 3DWhitestrips. Make sure to use the product as directed to limit chances of these occurring. If you do experience any tooth sensitivity, try Crest 3DWhitestrips 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 3DWhitestrips, 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 3DWhitestrips do not harm tooth enamel and are safe to use, so you can use one pack right after another. With that said, Crest 3DWhitestrips 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 3DWhitestrips Professional Effects or consulting a dentist.
Although extensive consumer and clinical testing was done to establish the efficacy and safety of Crest 3DWhitestrips, we recommend following the usage instructions provided for each product. Longer wear time may cause tooth sensitivity and/or gum discomfort for some users.
Try applying Crest 3DWhitestrips 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 3DWhitestrips 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.
Do not smoke while wearing Crest 3DWhitestrips. 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 3DWhitestrips to achieve the desired result. However, if you are still unsatisfied with your Whitestrips, Crest White Smile offers a 60-Day Satisfaction Guarantee and will refund your purchase within 60 days. You can call 1-800-208-0169 for more information.
LED Accelerator Light
The Crest LED Accelerator Light is backed by 15 years of advanced whitening technology, and uses the same type of light technology used by dentists. The peroxide in the Crest 3DWhitestrips and Crest Whitening Emulsions whitens hard to reach/tough set-in stains. Then, the blue light further weakens the stains to dramatically boost the whitening results.
Follow the usage instructions outlined in the package and then turn on and apply the LED Accelerator Light. The LED Accelerator Light will beep to notify you the lights have turned off in case you can't see it while in use.
The Crest LED Accelerator Light beeps to notify you the lights have turned off in case you can't see it while in use.
