Teeth Whitening Strips

When doing your research, you'll come across dozens of whitening strips, many of which will claim to be "the best." Of course, they can't all be. Since most of the real benefits and risk factors are hidden in the fine print, figuring out which ones are better than the rest is challenging for shoppers.

The best teeth whitening strips will have a low enough concentration of peroxide that sensitivity won't be an issue. Clinical research has shown up to 15% peroxide to work for this, but most studies point to 10% as the "sweet spot." 

Since PAP is newer, there are fewer clinical studies available. Still, a 2021 study is among the several that have been published in the last few years pointing to PAP’s effectiveness as a whitening agent.

Your teeth whitening strips should also have fortifying ingredients that add to the whitening process. Coconut oil is an excellent ingredient to look for that won't always be advertised on the front page of a product. Since it works to kill the plaque-causing bacteria on your teeth, it can enhance your whitening and strengthen your teeth overall.

NatruSmile Teeth Whitening Strips are ideal for teeth whitening because they're developed with sensitivity in mind, contain natural additives (organic coconut oil) that amplify the impact of your whitening treatment, and ensure you achieve your long-lasting smile as quickly as possible.

Teeth whitening strips do expire. Like most whitening gels and bleaching products, their shelf life is usually about 12 months (for PAP and hydrogen peroxide strips).

Using expired teeth whitening strips won't necessarily damage your teeth, but it won't yield any results, either. Medical and dental professionals strongly advise against using them for this reason.

If your whitening strips expire, you should order or purchase new ones. To maximize the value you get from whitening strips, only purchase them when you plan on whitening shortly after. Otherwise, you might forget about them or need to replace them.

When used properly, effects from NatruSmile Teeth Whitening Strips last for at least six months. Some NatruSmile customers see glowing results for over a year after their initial treatment.

To ensure your results last, we strongly advise you to maintain a solid oral health routine, including brushing your teeth twice per day and flossing at least once. If you can, avoid drinks like coffee and wine, which can stain your teeth and detract from the smile you worked so hard to get.

To get the most out of your whitening treatment and amplify your results for a longer period of time, use NatruSmile Teeth Whitening Toothpaste or NatruSmile Teeth Whitening Mouthwash, which have lower concentrations of whitening agents designed for maintenance and touch-ups for surface stains that will inevitably appear.

NatruSmile Teeth Whitening Strips do not damage your enamel when used properly. We've rigorously tested our products to ensure they contain safe concentrations of ingredients, and take extra precautions to ensure our products are gentle on your teeth.

If you follow the instructions included with NatruSmile Teeth Whitening Strips, including limiting usage time to two weeks (or one package), then you can rest assured that your enamel will be safe.

Teeth whitening strips are not intended for use by anyone under the age of 18. Since children's teeth and gums are still developing, we recommend they see a dentist before attempting any at-home whitening products. 

Furthermore, whitening treatments are designed only to work on natural teeth, so they won't have any effect on children's dentures or other prostheses. They also won't help if your child wears traditional braces, which cover most of the visible surface of their teeth.

Some whitening strips cost as low as $10, while others go for upwards of $100. In reality, the best whitening products are somewhere in the middle—the lowest-cost option probably won't yield great results, and you don't need to spend that much to get the best possible whitening that strips can offer.

NatruSmile Teeth Whitening Strips are priced at $27.99 per pack, making them one of the most reasonably priced products on the market. To sweeten the deal, we also offer quantity discounts. If your whole family or friend group wants to get whiter teeth, order in bulk and save!

You can use teeth whitening strips up to twice every day for the duration of your whitening period. If you whiten once per day, your treatment will last two weeks. If you whiten twice per day, your treatment will last one week.

Whitening any longer than this two-week period will not result in any further whitening, but it might irritate your teeth and gums and cause irreversible damage to your mouth. 

After a full 7- or 14-day treatment, you should wait at least six months before using teeth whitening strips again.

You can brush your teeth before or after your whitening procedure, depending on your personal preference. Do not brush your teeth immediately before or after whitening. This will negate some of the positive effects of your whitening strips and potentially cause greater sensitivity. 

It's best to brush your teeth before you apply the strips, especially since our teeth whitening strips leave a minty feeling in your mouth anyways. In either case, wait at least 30 minutes between brushing and whitening in order to ensure effective results.

Whether or not you can use whitening strips while wearing braces depends on the type of braces you have.

If you have metal, ceramic, or clear plastic braces, using whitening strips on the areas around the brackets won't work because it won't be able to reach the spaces under the brackets. This could result in an uneven whitening effect that will show up as small discolored squares on your teeth after your braces are removed.

Lingual braces and Invisalign trays are different. You can use our whitening strips directly on your teeth because the Invisalign trays are removable. For the same reason, you should be able to use whitening strips with lingual braces since they do not cover the surface of your teeth.

Pregnant and nursing women should always avoid teeth whitening treatments, including whitening strips. Pregnancy gingivitis, the term used to describe the gum inflammation and irritation directly resulting from hormonal changes throughout pregnancy, affects up to 75% of women. In the context of teeth whitening, this means that products that use bleaching agents may cause further irritation or damage. 

For these reasons, it's best to wait until after giving birth before whitening your teeth. This will help prevent any potential risks of increased sensitivity, gum tissue damage, or oral infection.

Plenty of NatruSmile customers see some results after one or two whitening sessions, especially if their teeth were extremely yellow before. As you progress through your pack of whitening strips, you'll gradually see your smile begin to whiten multiple shades. After you complete your treatment (7 days, twice daily), you will see vibrant results that look dramatically different from where you started.

The amount of time it takes to see results and the extent to which they appear depends on the initial color of your teeth, the type of staining underneath the surface, and how you alter your habits to accommodate the whitening process.

Teeth whitening products, such as strips, can safely and effectively eliminate both internal and external teeth stains. But there are some caveats to be aware of. 

Overexposure to peroxide (and other teeth whitening agents) can result in hypersensitivity and demineralization of your enamel. If you use teeth whitening strips for too long (e.g., several weeks or months), leave them in your mouth for longer than 30-60 minutes, or couple them with too many other whitening products and treatments, you run the risk of doing damage to your teeth. 

In some cases, tooth sensitivity is unavoidable. This doesn't necessarily mean the product is unsafe or that your teeth have an underlying problem. Tooth sensitivity is a common problem that affects tens of millions of people, and powerful whitening agents sometimes exacerbate that.

To help you avoid causing permanent damage to your teeth or experiencing short-term pain, we include a detailed guide to using our whitening strips. It's important to read this guide and familiarize yourself with proper usage before you begin to whiten.

Teeth whitening strips are the most popular at-home whitening treatment, so they are available online and in-store at most major retailers.

We recommend shopping online for teeth whitening strips. Online, you'll have the freedom to do all the research you need and there will be more options available.

NatruSmile Teeth Whitening Strips are available for immediate worldwide shipping at the top of this page. Alternatively, you can find them at select specialty online and brick-and-mortar retailers.

Our teeth whitening strips are highly effective and help customers achieve multiple shades of whiteness in as little as one week.

Numerous clinical studies and thousands of dental professionals around the world recognize teeth whitening strips as a safe and effective whitening treatment, and we went the extra mile and achieved professional approval for our own products.

It is worth noting that due to the lack of professional oversight, all at-home teeth whitening products are at least somewhat less effective than their in-office counterparts. Still, teeth whitening strips help customers save lots of money while whitening their teeth to an extent they never thought possible.

Some NatruSmile customers report a low degree of sensitivity when using our products, including whitening strips. The sensitivity generally lasts less than 24 hours, but may persist for a day or two after whitening. This side effect is not unique to NatruSmile products and occurs in every whitening treatment across the board.

Approximately 1 in 8 people suffer from hypersensitivity in their tooth enamel, and many more find that whitening agents cause this, even if they don't otherwise have any problems. In one recent study, teeth sensitivity was observed in just about every case, across multiple different whitening methods. It also found that sensitivity is at its worst when whitening products have a 30% to 40% concentration of the bleaching agent.

NatruSmile Teeth Whitening Strips are nowhere near that high of a concentration (in either of our whitening strips offerings), which helps prevent an uncomfortable whitening experience and quell any fear that our products will irritate your teeth and gums. Some sensitivity is also preventable with the use of desensitizing agents.

Using whitening strips can cause dry mouth or teeth dehydration as a rare side effect. This occurs because the substances can penetrate the enamel since our teeth are porous. Although the side effect usually subsides within a few hours of use, it could be a concern if it persists.

To prevent dehydration after you whiten, there are certain measures you can take to rehydrate your teeth. The best way to do this is to stimulate saliva production by drinking plenty of water and chewing sugarless gum. You can also reduce dehydration by drinking more water throughout the day and reducing your intake of caffeine and alcohol.

There are several steps you can take to stop teeth sensitivity that results from whitening strip treatment. The best way to reduce sensitivity is to find a desensitizing mouthwash or topical gel that you can apply before your whitening sessions. They are usually readily available at most stores and won't cost much to buy.

You could also try reducing the amount of time that the whitening strips are on your teeth. If you wear them for too long, it could increase the risk of sensitivity or other side effects. NatruSmile Teeth Whitening Strips only need to be worn for 30 minutes a day, but reducing the duration beyond that will still yield some results.

You should avoid eating and drinking for at least 30 minutes after using whitening strips. The substances used in the strips will still be present on your teeth during this time. If you eat or drink during this window, the substances may react with the food or beverage, which could lead to staining or discoloration, negating the effects of your whitening treatment.

It's also important to avoid certain foods and beverages throughout your entire treatment, including coffee, soda, wine, and any foods that are highly pigmented or acidic.

Leave your whitening strips on your teeth for 30 to 60 minutes, depending on your sensitivity level and tolerance and your level of staining. Those with deeper stains will benefit from an hour-long whitening session, while lesser surface stains can be addressed with a shorter duration. 

Removing the strips earlier than 30 minutes will not yield the best results because the gel needs more time to work its way into the enamel. Consistently using our product for over one hour will heighten your sensitivity and potentially damage your teeth.

Your whitening treatment should occur at least 30 minutes before or after brushing your teeth. Brushing your teeth immediately before or after whitening strips can disrupt the effectiveness of the gel in the strips and cause greater sensitivity. Waiting at least 30 minutes between brushing and whitening ensures that you will get the most from your treatment. 

That said, brushing shortly before applying whitening strips ensures there is no plaque buildup that could negate the effects of the treatment.

If your teeth hurt after using teeth whitening strips, there are three potential reasons.

Most often, sensitivity is nothing more than a side effect of the whitening treatment. Since hydrogen peroxide and PAP are bleaching agents, some customers experience lingering sensitivity even though the concentration is comparatively low and they applied the product correctly.

Sensitivity is also a result of misapplication. When our whitening strips aren't used as intended, they can cause pain and discomfort due to overbleaching. The same is true for overuse of whitening products—if you use our strips and professionally whiten your teeth simultaneously, for example, you will almost certainly have some degree of discomfort or pain.

If you whiten your teeth while you have untreated tooth decay, cavities, gingivitis, or gum disease, you will also experience a heightened level of sensitivity after your treatment. If you were previously unaware of these problems, pain after whitening could be a telltale sign of something more serious.
