You have no items to compare.
Do NOT brush immediately BEFORE applying strips. To avoid gum irritation, allow for some time to pass after you have brushed your teeth to apply strips.
Eating while wearing a strip is not recommended. Doing so will affect whitening results.
No, do not wear Whitestrips overnight or while sleeping.
We have not conducted research with children under 18. No Crest Whitestrips product is intended for use in children under the age of 18. The new teeth whitening legislstion suggests the minimum age for any teeth whitening is 18.
Since the left over gel isn't harmful, you can do any of the following:
No. Whitestrips will not cause your teeth to stain faster.
It is not recommended. No data is available on the safety of effectiveness of adding additional peroxide to a Crest Whitestrips. Also, adding anything to the strip will affect its ability to stick to the tooth surface, thus affecting whitening results.
Yes, after using Whitestrips, you can brush gently.
No. If cut into smaller pieces, the strips could dislodge from the teeth and have the potential to become aspirated.
It is okay to drink water while wearing the high adhesion Crest Whitestrips Advance Seal whitening strips. Drinking while wearing our other strips is not recommended. Doing so will affect results.
No, the strips conform to the surfaces of your teeth, so flossing would pull the strip out of place.
Using a strip over again will not provide any tooth whitening benefits. Even though there may be some gel remaining on the strip when you take it off, most of the peroxide is gone.
No, do not smoke while while wearing a strip. Doing so could cause the strips to dislodge from the teeth, thus affecting the whitening results.
We do not recommend switching strips. Although the strips would still work if switched, each upper strip is designed specifically to cover the area of your upper teeth while each lower strip is designed specifically to cover the area of your lower teeth. These shapes were designed to keep the strips in place while covering those teeth that show when you smile. Wearing a lower strip on your upper teeth will result in you covering less area on your upper smile teeth.
Yes. We recommend using Crest Vivid White while you're whitening your teeth. To help maintain whiter teeth after using Crest Whitestrips, we recommend using a Crest Whitening Toothpaste to gently polish away surface stains daily.
It's OK to rinse with an over the counter mouthwash after using Crest Whitestrips. We recommend using Crest Whitening Rinse to help maintain your whiter teeth.
Crest Whitestrips is only intended to whiten natural teeth.
Yes, however do not store the strips in the sun or heat.
We don't offer a tooth color comparison chart. However, after a few days, many people who use Crest Whitestrips can already see a brighter difference in their smile. Friends or family may also begin to comment on the change! You can also see the result by looking at your back teeth.
Crest Whitestrips are thin, flexible strips that are coated with a tooth whitening gel containing peroxide and are designed to conform to the shape of your teeth. They work by keeping the whitening gel on your teeth long enough to get at stain build-up below tooth enamel to visibly whiten your teeth. Crest makes 30-minute twice a day strips as well as 5-minute once a day strips for more convenient whitening
It is best if you do not brush your teeth immediately before applying strips. Open the pouch and remove the strip. Peel the strips from the backing liner and align with gum line. Press gently for good contact. Fold the rest of strip behind teeth to keep in place. Wear strips for required amount of time, then remove and discard.
The results will last for as long as 18 months to 2 years but this is influenced by the eating and drinking behaviors of the patient as well as other factors such as taking certain medications and smoking. Additional treatments such as the use of the NATURAL+™ Home Kit can improve and extend efficiency. Another very important factor to ensure long lasting results is to maintain excellent oral hygiene practices.
It is recommended to avoid such during whitening and for 1 week after tooth bleaching. McCann Agency Ltd however recommends not changing your lifestyle. If you feel that your teeth have yellowed over time, it is okay to do touch-up bleaching 1-2 applications every 4-6 months as needed.
Generally, immediately after bleaching, the color will fade slightly and then remain stable for approx. 6 months to a year, sometimes longer. It is recommended for maintenance to touch up your smile every 4-6 months with 1-2 applications.
Results vary. Some teeth whiten dramatically in just a few days, while others can take a few months. The majority of people whiten within 2-3 weeks. The more yellow versus gray color you have in your teeth, the better the bleaching. Grey enamel similar to that of Tetracycline (antibiotic) staining is more difficult to bleach and can take a few months to achieve a result.
As brands of syringes vary in the amount of bleaching gel, it is easier to quantify by using the ml’s or cc’s (same thing) and NOT the number of syringes. It is generally accepted that each treatment requires approx 0.5 ml’s (cc’s) of bleaching gel per application. The average person with yellow teeth will therefore needs about 10-15ml’s (cc’s). Keep in mind that you may need to do touch-up's at a later date to maintain the whitening. Grayish colored teeth are more difficult to whiten and will require additional bleaching gel. Keep in mind that only a small droplet needs to be placed on the inside surface of the outer wall of your custom made whitening tray opposite each of the front 8 teeth. It is not necessary to whiten the teeth towards the back of your mouth as these teeth are not usually visible when you smile.
It's not recommended. Start over with a new strip.
It is also normal that certain areas of the tooth such as areas of decalcification will respond more rapidly to bleaching resulting in blotchiness at first while the rest of the tooth catches up as one continues to bleach. The blotchiness is the first to fade after stopping resulting in a more uniform appearance.
To our knowledge nothing detrimental has been documented and microscopic research shows no changes to the tooth surface with use of 10% bleaching solution. Most research available was initially done with a 10% concentration. There is no literature that we have come across showing any structural changes or irreversible damage to the tooth structure whatsoever.
It is not recommended. The strips provided for your upper and lower teeth are designed to fit the front teeth only. Using the strips on the back teeth may result in the strips coming loose and eventually falling off during the wear period.
Yes. With all the Whitestrips products except Supreme you can use one strip right after the other (back-to-back). Wear strips for the time instructed, then remove; rinse or wipe if needed, then apply a second strip. Remember if you do get any tooth sensitivity cease use and consult your dentist. Once you have used your initial Crest 3D Whitestrips it is recommended that you use Crest 3D Stain Shield the ongoing 5 minute a day treatment.
NATURAL+ is a unique patented formula, with no pain or side effects, and no hypersensitivity to gums, enamel and dentin.
No. The NATURAL+TM Gel includes as the main active agent, an aqueous compound with two types of hydrogen peroxide which has been fully tested to be 100% harmless, with no residuals and is totally ecological. The Meodental patented formula has added Dead Sea minerals, Calcium and Fluoride which also helps fortify and protect enamel, dentin and gums.
We do not recommend using Crest Whitestrips that have passed the best used by date, they won't work as well for you.
Make sure that the bleach covers the entire surface of the tooth and not just the bottom half. The average tooth will usually have a seamless whitening transition from whiter at the bottom of the tooth (biting surface) to less white towards the gum line. This is normal and an expected result. This is due to thinner enamel in this area allowing more show through of the tooth color. Very few cases have total uniform whiteness. With grayish teeth, the transition is occasionally somewhat more noticeable. One might see a demarcation area / line between the 2 areas. Keep in mind that whitening fades and the tooth will in most instances gradually blend. In some cases that are extremely resistant to bleaching, one might consider bonding or veneers as an alternative treatment.
NATURAL+TM is intended for people who are over the age of 15 years. NATURAL+TM is not recommended for woman who are pregnant or breastfeeding. Those wishing to use NATURAL+TM should consult with their dentist and/or doctor first.
All bleaching gel causes some degree of tooth sensitivity. This is sensitivity to cold/hot fluids and even air can cause discomfort. This is normal and an expected side effect. Some of the brands of bleaching gel contain desensitizing agents which claim to alleviate post bleaching sensitivity. From customer feedback, this doesn’t seem to be noticeably effective. All bleaching causes tooth sensitivity and we recommend to either discontinue use for a few days and the sensitivity will dissipate within 24-48 hrs. Don’t be concerned as bleaching does not need to be done consecutively. You will get to the same whitening point, it will just take a little longer. A better alternative option is to use Dr. Collins Desensitizing Gel which is applied after bleaching in the same manner as the bleach. For maximum benefit use the Dr. Collins Desensitizing Gel and a desensitizing toothpaste like Sensodyne or any of the over the counter toothpastes containing potassium nitrate as the active ingredient will help.
There is no objective research at the present time comparing the different tooth whitening systems or the effectiveness of various bleaching gels currently available. They all work, some bleaching gels just gets you there quicker. They will all eventually get you to the same bleaching plateau (maximum whitening). Results vary, some teeth whiten very well as others show minimal changes no matter what product is used. We recommend to stay with a brand or strength that has worked for you and to maybe try another brand or strength if you are unhappy with your current bleaching results. Ultimately the choice of bleach agent is really a personal one.
General day to day consumption habits such as drinking coffee, tea and wine as well as smoking, may all lead to the staining of the teeth over a period of time. The use of a certain type of antibiotics (Streptomycin) during tooth formation can also lead to what is known as tetracycline stains.
Try using a mirror to properly apply the strips, making sure the strip is in good contact with the teeth. If the strips begin to slip, close your mouth and create suction to tighten the strips up again. Don't touch the strips excessively with your tongue. You can try gently tucking the strip in the spaces between your teeth with your fingernail, then folding it behind your teeth. You can also try new Crest Advanced Seal- specially designed to strongly adhere to your teeth better with a new revolutionary formula.
The white spots are temporary. These spots are not harmful and will go away. The white spots are caused by a loss of water from the tooth enamel. This water loss is not harmful and will go away within a few hours.
You can skip or miss a couple of applications without affecting your whitening benefit.
If your teeth are significantly discolored, you may need to use 2 boxes of Crest Whitestrips initially to get the desired result. We recommend using a Crest whitening toothpaste to gently polish away surface stains daily.
You're experiencing a natural reaction between your saliva and the hydrogen peroxide on our Whitestrips. Saliva increases whenever you place an object of any kind in your mouth. Together they make a foam.
Teeth whitening is a process of cleaning and removing stains from teeth in order to restore their original and natural color. The process of teeth whitening developed by Meodental referred to as the NATURAL+TM process, involves the use of Meodental's patented NATURAL+TM Gel and NATURAL+TM Lamp.
There are 2 main bleaching ingredients. Carbamide peroxide (e.g.Day White & Bdazzled) and hydrogen peroxide (e.g. Crest Whitestrips,and Nite White). Comparatively, a 7.5% hydrogen peroxide is equivalent to a 16% carbamide peroxide while a 9.5% hydrogen peroxide is equivalent to a 26% carbamide peroxide.
Carbamide peroxide actually breaks down into hydrogen peroxide. Patients must wear Nite White for a longer period of time so that the carbamide can break down in to hydrogen peroxide, the active ingredient. The only real difference for you is the wearing time. Nite White was first developed in a 10% solution to be used overnight, allowing time for the carbamide peroxide to breakdown into hydrogen peroxide. With the demand for a more effective bleaching agent, the 16% and 22% were launched. The 16% can also be used overnight while the 22% is used for 1 hour only. Both Day White and Nite White will take you to the same bleaching end point.
Theoretically it would appear then that Day White 9.5% would be more effective but there is no research to substantiate this. Likewise Bdazzled Xpress is 29.5% carbamide peroxide and Bdazzled Professional 24.5% carbamide peroxide.
Generally the shelf life of most bleaching gel is approx. 2 yrs if refrigerated and 1 yr un-refrigerated. Un-refrigerated bleach should be stored in a dry cool environment. The wearing time is based on the strength of bleaching gel.
Results will vary from patient to patient depending on color of the teeth prior to treatment; however, patients can expect improvements of up to 8 lightening shades (VITA Scale).
Prolonged contact with your skin may cause small, white spots on your skin. These white spots are not harmful and will disappear. Be sure to rinse off any gel that gets on your skin.
NATURAL+TM must be purchased through your dentist. The NATURAL+TM Professional Kit is administered by a dental professional and the NATURAL+TM Home Kit is supplied by your dentist who will explain the procedure to ensure maximum results as well as assist you in forming the trays for your mouth.
No research has been done into bleaching teeth while nursing or pregnant, so manufacturers for liability reasons recommend NOT to bleach while pregnant or nursing.
All bleaching agents used to whiten teeth will only work on natural tooth structure. This means that all dental work including but not limited to bonding, veneers, crowns (caps) and bridges will NOT bleach or whiten. All dental work would need to be replaced to match the newly whitened teeth.
No…Results vary. Some teeth whiten dramatically in just a few days, while others may take weeks to months to show a difference, if any. The more yellow versus gray color you have in your teeth, the better the bleaching result. Grey enamel similar to that of Tetracycline (antibiotic) staining is more difficult to bleach. Some normal teeth will achieve only minor whitening improvement no matter what product you use. Results cannot be guaranteed.
Yes, however, smoking stains can be difficult to remove and may take a little longer. If you continue to smoke, your teeth may discolor faster.
Although Crest Whitestrips that has passed its expiration date is still safe, we don't recommend using it past its expiration date, as the whitening ingredient's efficacy will be weakened.
