Yes, Crest whitening strips do actually work. Crest Whitestrips use hydrogen peroxide, which is the same active ingredient used by dentists and professional teeth-whitening services. The two most popular types of strips, Crest 3D Whitestrips and Crest Whitening Strips, provide noticeable results in as little as three days and results can last up to 12 months after use.
Clinical studies have shown that both types of strips can whiten teeth up to three shades in as little as 20 minutes of use per day. When used as directed, Crest whitening strips can whiten teeth, reduce tooth sensitivity, and help remove surface stains.
It is important to note, however, that Crest whitening strips will not lighten tooth-colored fillings, crowns, or veneers. Also, if using over-the-counter whitening strips, it is important to follow the directions carefully.
For optimal results, it is recommended to use Crest whitening strips for at least four weeks.

How effective are Crest whitening strips?
Crest whitening strips can be an effective way to whiten teeth, although the results depend on the individual and the individual’s lifestyle habits. Studies have found that Crest whitening strips can whiten teeth by up to four shades, and have been shown to be safe and effective when used as directed.
Crest Whitening Strips are very easy to use and can be applied in under 30 minutes; however, they are not designed to correct any major dental issues and their effects are temporary.
Crest Whitening Strips are thoroughly researched, clinically tested, and approved by the American Dental Association, so they can be a great option for those looking to improve the color of their teeth.
It is important to note that Crest Whitening Strips work best on yellow or brown teeth, and may not be as effective on grey or purple teeth.
It is also important to understand that Crest Whitening Strips may not be as effective for smokers and people who regularly consume staining products such as coffee or red wine. Additionally, it is important to remember that Crest Whitening Strips are not a substitute for regular dental cleanings and check-ups from your dentist, which are necessary for healthy teeth.
Do Crest Whitestrips work on yellow teeth?
Yes, Crest Whitestrips can work on yellow teeth and can help whiten them. Whitening strips contain hydrogen peroxide or carbamide peroxide, which helps to break down the microscopic stains on teeth. Crest Whitestrips are designed to be worn for 30 minutes a day for 10 days, to give you a results of a brighter, whiter smile.
While it is true that deep, yellow stains on teeth will take longer to whiten, the active ingredients in Crest Whitestrips can still help to reduce the appearance of yellow teeth over a period of time and with continued use.
In addition to using Crest Whitestrips, maintaining a good oral hygiene routine and seeing your dentist regularly can also help to ensure that your smile is both healthy and white.
Do dentists recommend whitening strips?
Yes, dentists do recommend whitening strips. The active ingredient in the strips, hydrogen peroxide or carbamide peroxide, is safe to use according to the American Dental Association (ADA). The ADA recommends that you check with your dentist first before using them, as different individuals may have different sensitivities.
It is recommended that you follow the instructions on the product label carefully. Generally, it is recommended that you use whitening strips for no more than two weeks at a time, and that you use them no more than two times per year.
Additionally, it is advised to use a toothpaste that contains fluoride to help protect you from tooth sensitivity that can occur when using whitening strips. Overall, it is best to consult your dentist to determine whether whitening strips are the best option for you.
Do I brush my teeth after whitening strips?
Yes, it is recommended that you brush your teeth after using whitening strips. This will help to remove any residue that may be left behind and help prevent any irritation or staining on your teeth. Additionally, brushing your teeth after whitening strips will help to prevent the bleaching effects from deteriorating any tooth enamel.
Make sure you rinse your mouth thoroughly after brushing, to ensure that no whitening product or residue remains on your teeth. While it is not required to brush your teeth after whitening strips, regular brushing and flossing are important parts of an effective oral hygiene routine regardless of whether you are using whitening strips or not.
How many times do you have to use Crest White Strips to see results?
The amount of times you need to use Crest White Strips varies from person to person, and it will depend on the level of whitening you are looking for. Generally, Crest recommends using their whitening products twice a day for 30 minutes, over the course of 14 days.
For optimal results, you should continue to use Crest White Strips until you have achieved the desired whitening effect. After that, touch up whitening may be needed every few months. With proper use and care, Crest White Strips have been proven to whiten teeth an average of 2-8 shades brighter.
How many Crest strips do I need to see results?
In order to see results from using Crest Whitestrips, you need to use the product as directed and for the full amount of time indicated on the box. Depending on the type of Crest Whitestrips you are using, the amount of time necessary to see results will vary.
Generally, you will need to use Crest Whitestrips for a period of 10 days or more. You will likely see some initial results after your first application, but the full effect of your whitening will not be visible until you have used them for the full amount of time.
In short, you need to use at least 10 full strips in order to see the results that Crest Whitestrips promise.
What happens if you leave whitening strips on longer than 30 minutes?
If you leave whitening strips on longer than the recommended 30 minutes, it is possible that the strips may cause irritation to your gums and other areas that they come into contact with. This can be an uncomfortable and sometimes painful experience, so it is important not to over-expose your teeth to the whitening strips.
In addition to causing irritation, leaving whitening strips on for an extended period of time may lead to an excessive amount of exposure to hydrogen peroxide which can be hazardous if not used properly.
The hydrogen peroxide in the strips is the active ingredient that actually whitens your teeth, but if too much is released it could erode the enamel on your teeth. This can leave your teeth feeling sensitive and weak, and can cause permanent damage if not treated.
It is important to follow the directions on the package and never leave the whitening strips on longer than the recommended 30 minutes to ensure your safety and well-being.
Why do my teeth look more yellow after whitening strips?
It is possible for your teeth to look more yellow after using whitening strips. This is because the active ingredient in the strips, hydrogen peroxide, can cause your tooth enamel to become more porous and absorb more stain from food and beverages.
Whitening strips can also cause temporary dehydration or shrinkage of your teeth, which can make them look yellowish. The strips tend to be most effective on teeth that are slightly discolored and not stained from years of smoking or drinking highly-pigmented beverages like coffee and tea.
If your teeth were severely discolored prior to using whitening strips, this can cause them to look even more yellow after use. Additionally, some whitening strips may contain abrasives that may scratch the enamel on your teeth and make them look yellow.
To minimize yellowing of your teeth after whitening strips, you should use whitening strips that are formulated for discolored teeth, abstain from consuming pigmented foods and beverages while using the strips, and brush your teeth and rinse with water after each use.
If the yellowing persists, try switching to a different brand of whitening strips and never leave them on the teeth longer than directed. If needed, you may also want to speak to your dentist about other whitening options available for your situation.
How many Crest White Strips does it take to see a difference?
The amount of Crest White Strips needed to see a difference will depend on the individual and their teeth. Generally, teeth whitening strips can take anywhere between one to two weeks of daily use to see noticeable results.
For individuals with especially discolored or heavily stained teeth, it may require using a higher number of Crest White Strips to see a bigger difference. A good rule of thumb is typically at least a month of daily use to see a noticeable difference.
Additionally, it is important to ensure that the strips are being used as directed in order to achieve the best possible results.
How long does it take to see results from Crest White Strips?
Generally, results from Crest Whitestrips take anywhere from 3-10 days, depending on the individual and the system they use. When using Crest Whitestrips, users will see a noticeable difference in their smile within a few days.
After 10 days, users typically see their whitest smiles. For normal long-term maintenance, Crest Whitestrips can be used every 6 months. However, it is important to follow the directions on the crest package for optimal results.
Additionally, individuals with more severe staining may need to use Crest Whitestrips more often than others. It’s important to note that Crest Whitestrips are designed to remove surface level staining, and will not have an effect on deep, intrinsic staining.
For more severe cases of staining or tooth discolouration, individuals may need to consult with their dentist.
Can you do 2 Crest Whitestrips a day?
No, you should not do two Crest Whitestrips a day. Crest Whitestrips are only meant to be used once per day, and you should always follow the directions included with the product. Additionally, overusing Crest Whitestrips may cause tooth sensitivity and gum irritation.
Even if you get faster results with 2 Crest Whitestrips a day, it may be unwise due to the potential side effects. It’s best to wait until the recommended time has elapsed before using another set of Whitestrips, if desired.
Is it OK to miss a day of teeth whitening?
It is generally not recommended to miss a day of teeth whitening. Depending on the type of whitening you are using, missing one day could have a negative impact on your results. For example, if you are using a tray-based whitening system where you have trays with a whitening solution that you wear for a certain number of hours every day, then missing a day could cause uneven results with lighter and darker spots.
Alternatively, if you are using an at-home whitening system like whitening strips, you could miss one day and it probably won’t have too much of an effect, but it’s still not recommended if you want to get the best possible results.
Why can’t you use Crest White Strips after brushing?
It is generally not recommended to use Crest White Strips after brushing because the chemicals in the whitening strips could react with the chemicals in the toothpaste and potentially cause gum irritation or other side effects.
The strips contain hydrogen peroxide, which is a bleaching agent, and it can be irritating when exposed to the mouth in large amounts. Crest White Strips can cause gum sensitivity, which can be exacerbated if the strips are used directly after brushing with a toothpaste that contains ingredients like sulfur and abrasives.
In addition, some toothpastes contain surfactants, which can increase the risk of gum irritation with bleaching. Therefore, it is generally safer to wait at least 30 minutes after brushing before using Crest White Strips.
What strength of teeth whitening is best?
The ‘strength’ of teeth whitening is usually attributed to the concentration of hydrogen peroxide or carbamide peroxide in the tooth whitening product. Generally, the higher the concentration of either or both of these active ingredients, the stronger the whitening.
However, it is important to realise that higher concentrations of these active ingredients can cause irritation to the gums, teeth and other sensitive areas of the mouth. Therefore, it is best to use a whitening product with the highest strength that one can tolerate without causing any adverse effects.
The American Dental Association (ADA) advises that the ideal strength of hydrogen peroxide or carbamide peroxide concentration should not exceed 16%. Therefore, it is advisable to select a teeth whitening product with a concentration that is below this mark.
Additionally, it is recommended to use products with an ADA seal of approval, so that one knows that the product has been independently tested for safety and efficacy.
The best strength of a teeth whitening product ultimately depends on one’s individual preferences, budget and the severity of their discoloration. Those with more moderate discoloration and mild sensitivity may be more comfortable with a product that has a weaker concentration.
For those with more severe discoloration, a stronger, professional-grade whitening product may be necessary.
