Our ISmile Teeth Whitener Buying Guide

iSmile is a Fort Lauderdale, Florida-based company that specializes in teeth-whitening products. Regardless of the type of method you’re interested in trying, iSmile likely has a product for it. But choosing between the different types of whitening applications can be tough. They each have their pros and cons, so first you’ll want to narrow down the type of product you want to use.

One popular teeth-whitening method involves filling a tray with a solution, then applying it to your teeth. Some even include an LED light that promises to speed up the whitening process. This treatment is similar to what you’d get at a dental office, making it among the most effective home solutions you’ll find.

In recent years, charcoal whitening has grown in popularity, especially for those looking for a more organic solution. This method uses natural ingredients like coconut shells, olive pits and burned wood, which are combined and oxidized under extreme heat. Once brushed onto the surface of your teeth, it lifts toxins and odors, removing them from your teeth as you rinse.

Another option is whitening pens, which have one major thing going for them: portability. That convenience is unprecedented with teeth whitening. You can put it to work on your teeth whether you’re at home or on vacation, even taking it along with you to the office every day. It’s mess- and fuss-free, making it more likely you’ll stick with it over time.

Before you invest money into teeth whitening, look closely at what’s involved. Bathroom cabinets across the country are filled with half-used whitening treatments. If you have to use it every day for weeks, or worse, multiple times a day, you may start out with good intentions, but lose that ambition soon after. A solution that starts showing results in a matter of days may be a better option if you think you might lose steam once you’ve completed a few applications.

DWYM Fun Fact

While it’s easier than ever to whiten your teeth, the practice is nothing new. In fact, it’s believed that ancient Egyptians used a whitening paste made from ground pumice stone and wine vinegar to clean stains from the teeth. This tended to be a practice of the privileged, as white teeth were seen as a sign of wealth. But perhaps the most notable early teeth-whitening practice came from the Ancient Romans, who reportedly used urine to whiten their teeth. The ammonia in urine was believed to cleanse stains away. By the 1700s, consumers were relying on their barbers for dental care, where they would get an acid treatment that whitened them. Obviously, this practice wasn’t a good idea, and eventually, people realized it eroded the teeth, causing decay.

The ISmile Teeth Whitener Tips and Advice

  • If you choose to go with a tray-based kit, check into how the tray will fit onto your teeth. With some, you’re required to heat the tray to make sure it molds to your teeth, while others are built to automatically conform.
  • Products that whiten your teeth do so through the use of hydrogen peroxide or carbamide peroxide. This can cause gum irritation, in addition to leading to sensitivity in your teeth throughout the timeframe that you’re whitening. You may especially notice this when you’re drinking or eating cold items. A toothpaste made for sensitive teeth can help with this.
  • In addition to its organic ingredients, activated charcoal is often preferred because it’s easier on the gums. You also won’t have the tooth sensitivity you’ll experience when you whiten using products with peroxide.
  • Even if you get your teeth professionally whitened, the effects aren’t permanent. Your teeth will gradually lose that brightness again. This could take years or months depending on how often you eat and drink dark foods and liquids. Coffee and red wine can be especially tough on teeth, as can smoking. You can use a whitening toothpaste to extend the effects.
  • Even if you choose a whitening product that promises fast results, keep in mind that it will take time. Don’t plan to whiten your teeth the day before an important occasion. Instead, allow at least a week or two for consistent applications to pay off.
  • As advanced as at-home treatments have become, they work best if you use them every couple of years. Once stains reach a certain point, it will take a dentist to get your teeth where you want them to be.
  • There are some natural ways to keep stains at a minimum, including brushing after every meal and using whitening toothpaste or baking soda. Some foods stimulate saliva production, helping wash food and other debris away, including celery, apples, pears and carrots.
