Tips to Get the Best Results For people with deeper surface stains (also known as intrinsic teeth stains), we advise that you use the
Our Recommendation For The Best Time Based On Lifestyle
For those with busy mornings, applying whitening strips at night might be more convenient and effective. However, if you have a more flexible morning routine and prefer to start your day with a fresh, bright smile, morning application could be ideal for you.
Whiten your teeth just before you go to sleep
This is why it's best for you to perform whitening just before you go to bed, so that your teeth will not be exposed to any substances that could stain them. Rehydrating and remineralizing of your teeth will also naturally take place while you sleep.
Wearing for 6 hours or more at night will typically yield better results. We have a 10% carbamide peroxide gel, or a 16% carbamide peroxide gel – both designed to be worn overnight. These are the equivalent of 3.5% hydrogen peroxide and 5.7% hydrogen peroxide, respectively.
To get the best results, you must use your teeth whitening strips daily, however, using them more often or for a longer period of time than specified in the instructions can ultimately result in erosion of your teeth enamel, which can lead to sensitivity and other damage.
Brushing too soon could potentially damage this delicate layer and lead to tooth sensitivity or even enamel erosion over time. To strike a balance between these perspectives, dentists often recommend waiting at least 30 minutes before brushing your teeth after using whitening strips.
Whitening strips often contain peroxide-based chemicals to eliminate enamel stains, which may lead to temporary irritation and redness of the gums. This redness creates a visual contrast that can make the teeth seem more yellow.
Dentists can treat you with 6% hydrogen peroxide (the bleaching agent that whitens teeth) – this is nearly 6,000 times stronger than any over-the-counter tooth whitening product. Because of this, tooth whitening by a dentist will give you the very best results.
As such, you shouldn't bleach the teeth more than once per year, or more than is advised with your specific whitening system. Doing so can be extremely harmful for the teeth, permanently stripping the enamel and causing life-long, irreparable damage.
Brushing Before Whitening
Brushing away any surface dirt, plaque, or food particles allows the whitening gel to make direct contact with your teeth, perhaps resulting in more effective results. Clean teeth may also absorb the whitening solution more evenly, resulting in a more uniform whitening result.
The strips are applied to upper and lower teeth, once a day, for up to 30 minutes. Depending on the specific Crest 3D White Whitestrips product chosen, strips should be applied daily for anywhere from 10 to 20 consecutive days.
There is no safe way to do this overnight. Any product that claims to do this, just won't work. Whitening can take as little as 2 weeks though to show some improvement, and many patients see a difference after just a few nights of treatment.
The pores slowly close over the next two to three days, but during that time, your teeth are more susceptible to staining from foods and drinks. For at least the first 48 hours, it's best to avoid darkly colored foods and drinks, including berries, coffee, tea, red wine, and tomato sauce.
The pores in your teeth are slightly more open and can more easily allow stains in. Smile Brilliant and dentist professionals recommend whitening before bed as it reduces the opportunity for staining and gives your teeth the night to begin rehydrating and remineralizing.
You might be tempted to leave whitening strips on your teeth for a little longer, but this will increase the risk and severity of side effects like sensitivity and gum irritation. In some cases, overuse of whitening strips has even led to chemical burns on the gums.
No, most whitening strips are not designed for overnight use. Sleeping with them can increase sensitivity, gum irritation, and uneven whitening results.
Yellow teeth can regain whiteness through various methods, including good oral hygiene, professional dental cleanings, and teeth-whitening treatments. Stains from coffee, tea, or tobacco can be removed with adequate oral care, while professional procedures like bleaching or laser treatments offer quicker results.
You may store your teeth whitening gel in the refrigerator to optimize its shelf life. Do not store the gel in the freezer. For optimal results, we typically recommend 7 consecutive days of treatment.
To maintain your whiter smile, use up to two Crest 3DWhitestrips teeth whitening systems per year; or try Crest 3DWhitestrips Classic Vivid. These 30-minute once a day strips whiten and help protect your smile against staining.
No treatment can whiten teeth overnight, but some options are faster than others. Natural or over-the-counter treatment may take longer than treatments at the dentist's office. Even in the latter case, whitening is likely to require several treatment sessions of several hours each.
Crest 3D Whitestrips are our pick as the best teeth whitening strips overall because our tests determined that they had the best results with the most effective active ingredients.
Factors Affecting the Longevity of Whitening
Several factors determine how long your teeth stay white, including the type of treatment, your lifestyle, and your oral care routine. Foods and drinks like coffee, wine, and berries can cause staining, while smoking can lead to yellowing of the teeth.
