10 Mistakes to Avoid When Wholesale Teeth Whitening Kit - Cinoll

Importing teeth whitening kits from China may seem like an excellent way to make a quick fortune.

Goto Onuge to know more.

However, truth be told, importing wholesale teeth whitening kits is fraught with potential issues and problems. One little mistake could lead to huge losses not only financially but in your time too. As such, it is important to avoid making these mistakes when buying wholesale from China or when sourcing teeth whitening products from Chinese manufacturers.

This is the reason for this blog post: to help you avoid 10 crucial mistakes often made when buying wholesale teeth whitening kits.

Mistakes When Choosing Teeth Whitening Kits

Mistake 1: Not Finding a High-Quality, Customizable, Unique Product

When sourcing teeth whitening products from a Chinese wholesale website or supplier, one mistake that brands often make is to choose their items without being strict on the criteria.

All products should be of exceptionally high quality as well as being unique and customizable. Without such possibilities for personalization, the oral product is likely to come up against products that meet the exact specifications elsewhere. This means that customers may be less likely to buy the oral product from you. Making your product unique with an original twist will mean it will draw in a unique demographic and you will be able to sell more of your teeth whitening products.

Mistake 2:  Negotiating Heavily On Price

When you negotiate with a supplier you must make sure that there are no shortcuts or compromises in how your product is made.

Negotiating on price is typical in business but it should not be at the expense of quality. To ensure that you prevent a reduction in quality, you must produce a detailed checklist for quality control, specifying all your product’s smallest details. Also, hiring an inspector to check your product and examine it at the end of the process is an excellent way of ensuring its quality.

Mistake 3:  Selecting The Cheapest Suppliers

Many people opt for the cheapest possible suppliers as a way of maximizing profits. But, trust us, this does not often work. Sure, price should be an important consideration, but it is a mistake to think that the cheapest will be of high quality.

When you are locating suppliers for a new range or an existing product, price should be a factor but weighing up quality against potential profit margins is more important. You need to be able to ensure you can sell the products for the price customers are willing to pay whilst sourcing them at a reasonable cost and good quality. Balance is the key.

Mistake 4:  Failure To Verify The Suppliers Before Starting Mass Production

Your products must meet the necessary safety standards if you wish to sell them in the US and EU. If not, you are at risk of hefty fines and permanent sales bans. It is important to check the suppliers’ safety reports and documentation before you place an order so that you can assess whether they are compliant. If you do not do this it can be very costly, and your brand could be over before it has really had the chance to get going.

Mistake 5:  Choosing Products That You Are Not Passionate About

A common error in choosing a product that you want to import is choosing one that you think might sell rather than a product you strongly believe in. Of course, it would be inadvisable to choose any products that you do not believe would sell well but choosing a product without having an interest in it or without feeling strongly about its use means that selling it will be much more difficult.

Products that you think will be popular might not be, so ensure you believe in your products before buying them. This will increase your odds of being successful with your products.

Mistake 6:  Not Checking The Quality Of The Products Before Placing An Order

You need to ensure that your products are up to scratch. If you do not check this before placing an order you could be left with a lot of unfulfilled orders or a large stock of inventory that cannot be sold.

Essentially, it would be best if you could visit the manufacturer and their facilities and test samples of their products. However, not everyone has the means and finance to travel to China. As a result, ask for some samples to be sent to you. This may take a little more time, but it is essential if you want to avoid the quality-control trap and a potential wholesale nightmare.

Mistake 7:  Not Investigating the Suppliers Properly

When you find a supplier, you must talk to them and find out as much about them before doing business or jumping on a plane to meet them.

Search for the company online by Googling their business name and look them up on any Chinese marketplace platforms. Do not be put off by the language barrier – many Chinese businesspeople speak English. Arrange to talk to the suppliers via Skype or video call so that you can ‘meet’ them face-to-face before potentially meeting them in person. Ask for a tour of their offices and factories via video so that you can have a closer look at how they operate.

Mistake 8:  Failing to Tell Whether They Are a Legitimate Factory

As a brand, you need to know whether or not you are dealing with an actual manufacturer or a trading company. Some trading companies pretend to be manufacturers or fail to mention that they are simply operating as a trader. You must take care with this. You should ask to see the company’s business license, even if this is in Mandarin. This should tell you the type of company you are dealing with.

Look for the ‘Business Scope’ label on the license. This will give you a category list where the business can operate legally. This should provide you with all the information required to ascertain whether they are a wholesaler, trading company, or manufacturer.

Mistake 9:  Only Selecting Season-Specific Wholesale Items From China

It is important to select products that are not specific to any season. If they are seasonal, you will have to keep prices lower, and it could have just been a fad or a one-off for the season.

You need to buy products that have long-term sustainability and profitability and avoid season-specific products. You can introduce season-specific items once you are established with other products but do not buy them in bulk.

Mistake 10:  Failing to Know Your Suppliers’ Characteristics

You need to choose your suppliers wisely. You could come across a substandard service, poor delivery, increase in shipment rates, and other issues. Bad suppliers may increase rates after the deal or take your deposits and make excuses and there is little you can do. We recommend that you only choose suppliers that:

  • Get the balance right between cost and price
  • Will be efficient in communicating with you
  • Guide you through all the processes

Make you aware of any potential issues and recommend solutions to these problems.

The Best Teeth Whitening Products for Tough Stains - Health

The Best Deals Right Now

Find deals on the Crest Leave-on Teeth Whitening Kit with LED Light, $41 (was $60); and the Crest 3DWhitestrips Sensitive + LED Light Teeth Whitening Kit, $42 (was $51).

Teeth whiteners are an easy, convenient way to brighten your teeth a few shades at home, but they can also work under the enamel to remove built-up staining. The best teeth whitening products function by removing both external stains, like the ones you might get from your daily cup of coffee, and intrinsic stains, which typically need to be treated on a deeper chemical level.

While the results from at-home whitening kits won't be as drastic as professional treatment, Lena Varone, DMD, of the New York Center for Cosmetic Dentistry, says you should expect to see your teeth lightened by one to two shades depending on the product ingredient concentration, how long it's used, and the cause of your stains. 

  • What to Know About Teeth Whitening Kits

    All the dentists we spoke with agreed that at-home teeth whitening kits are safe and effective, but there are a few considerations to keep in mind:

    • Choose the type of product that works best for your lifestyle: Whether you decide to use trays, strips, an LED kit, or a pen, it’s really up to personal preference and lifestyle. Strips and trays tend to be the most convenient, while LED kits are a little more cumbersome and awkward to keep in your mouth. LED kits provide the fastest results, followed by strips or trays, and then pens. Pens are a convenient option for whitening touch-ups but don’t provide long-term stand-alone results. 
    • Opt for products with peroxide as the main ingredient: “Hydrogen peroxide or carbamide peroxide gels break down into water, oxygen, and reactive oxygen molecules,” Velayo explains. “These reactive oxygen molecules treat both the enamel and the dentin [and] by changing the stained molecules, the tooth becomes lighter.” Note that high peroxide levels (such as those 6.5% and up) can be uncomfortable for people with sensitive teeth, though.
    • Choose other active ingredients if you have sensitive teeth: Teeth whitening for sensitive teeth is possible at home, but Velayo recommends looking for fluoride, xylitol, hydroxyapatite, and potassium nitrate to help minimize sensitivity. Our top pick for sensitive teeth, the Snow Diamond Teeth Whitening Kit, contains hydroxyapatite. Our picks for best pen and best strips are both made by Lumineux and use natural ingredients, like sage, sea salt, lemon peel and coconut. Opting for products with lower levels of peroxide (less than 6%), such as the Crest 3D Whitestrips + LED Kit, can help with sensitivity, too.
    • Follow manufacturer instructions closely: Overexposure (using too much of the product or more often than recommended) can cause tooth sensitivity and wear down enamel. “Wearing away the protective enamel layer and exposing more of the soft, sensitive dentin layer is a bad idea,” says Cindy Roark, DMD, MS, Senior Vice President & Chief Clinical Officer at  Sage Dental based in Boca Raton, Florida. “The dentin underlayer is yellow, so it stands to reason that the more enamel you wear away, the yellower your teeth become.”
    • Consult with your dentist before at-home whitening: Cosmetic dentist Daniel Rubinshtein, DDS, in New York City, advises resolving dental problems such as gum disease and cavities before using whitening products. In addition, those with thin enamel are more likely to experience pain while whitening their teeth.
    • Remember that teeth whitening kits only work on natural teeth: Hovanisyan adds that whitening products will only lighten natural teeth and not work on restorations such as fillings, crowns, bridges, and implants.
  • How We Selected the Best Teeth Whitening Kits

    To select which teeth whitening kits to test, we spoke to dental professionals, cosmetic dentists, and dental professors to understand what products and ingredients work best. 

    To date, we’ve spent more than 250 hours testing 50 different whitening devices and products in our lab and at home, judging their effectiveness, comfort, and convenience.

    We used a tooth color chart to compare our tooth shade before using each product with the results during testing and after. In our lab test, we used products once according to manufacturer instructions, took the products home, and continued to follow the manufacturer's instructions for as long as recommended or up to four weeks.

    We made our picks based on the following criteria:

    • Ingredients: How effective your at-home teeth-whitening experience is comes down to choosing the right ingredients. We spoke to dentists to find out which ingredients work best—and in what formulations—to improve your experience. Using the wrong ingredients can lead to ineffective results or even cause enamel damage. We only tested products that include the ingredients recommended by experts we consulted, including hydrogen peroxide and carbamide peroxide. To account for people with sensitive teeth, we also considered products with fluoride, xylitol, hydroxyapatite, potassium nitrate, and natural ingredients, like sea salt, coconut, sage and lemon peel. 
    • Effectiveness: We made sure each teeth whitener removed stains or brightened teeth by at least one shade, depending on the product type. We prioritized kits that experts said should provide visible results within a reasonable timeframe.
    • Comfort: Several of our testers have sensitive teeth, so we ensured that teeth whiteners for sensitive teeth—typically with a non-peroxide whitening agent or a peroxide in a lower percentage—didn’t cause discomfort or irritation. Our testers also reported whether products were comfortable during use, with strips and LED devices often requiring up to 20 to 30 minutes per session.
  • Our Expertise

    Jaylyn Pruitt is an associate editor for Health. She’s covered health and wellness products since , including our list of the best whitening products for sensitive teeth. As an avid coffee drinker, she understands the convenience of at-home teeth whitening to keep her teeth bright. She spoke to dental experts and professionals for this story to discuss what to look for in teeth whiteners, how to deal with sensitivity, and how to manage expectations. The experts she interviewed included:

    • Lena Varone, DMD, of the New York Center for Cosmetic Dentistry
    • Bianca Velayo, DMD, of Green Valley Smiles Dentistry in Henderson, Nevada
    • Lucy Hovanisyan, DDS, of ProHealth Dental in Hoboken, New Jersey
    • Cosmetic dentist Daniel Rubinshtein, DDS in New York City
    • Cindy Roark, DMD, MS, Senior Vice President & Chief Clinical Officer at Sage Dental based in Boca Raton, Florida

Why We Like It

“LED lights help to activate and speed up the chemical process that whitens teeth,” says Varone. However, she cautions that adding light alone is not a cure-all. The active ingredients (usually peroxide), combined with the light, are what make it work. The active ingredients brighten the teeth. That will happen with or without the LEDs, but lights can make the process occur a bit faster, she explains.

The Crest Whitening Emulsion with LED Light impressed us with its ease of use, effectiveness, and comfort. Its simple, straightforward process, and the ability to carry on with normal activities during treatment make it practical and user-friendly. With noticeable results and a gentle formula that minimizes sensitivity, it provides an unparalleled whitening experience.

“The whitening process was very straightforward,” our tester said. “It was so easy that I honestly thought I was doing it wrong!” All we had to do was apply the gel, carry on with our daily activities for 30 minutes, and then wear the LED device in our mouth for three minutes—that’s it. The entire process takes about 33 minutes and is completely painless. The device doesn’t require charging, which is convenient, and it comes in a box with a small plastic stand for the wand and whitening product.

The product's instructions recommend use twice per day, but for faster results, you can use it up to four times per day. Even when our tester occasionally used it for four applications daily, she didn’t feel any irritation. The results were noticeable, lightening our tester’s teeth by about two shades. It's easy to apply and comfortable to wear, making it worth the investment for quick, effective whitening. “This product was by far the most pleasant whitening experience that I have had,” our tester said. “I even took a Zoom call with the product on my teeth, and no one noticed a thing.”

It's Worth Noting

It’s hard to multitask when using the LED light. You only need to use it for 3 minutes each time, but it’s cumbersome to hold in place and slightly uncomfortable.
