Can Whiter Teeth Give You a Brighter Tomorrow?

Teeth whitening kits are a rising trend. But why? It might be because whiter smiles boost your confidence and make you smile more. Good deal! If you’re considering different ways to whiten your teeth and brighten your smile, you’re in the right place. In a few minutes, you’ll learn how to whiten teeth for pennies each day, which teeth whitening kits are the best, and which is the best way to whiten your teeth at home and which are the best teeth whitening for sensitive teeth.

How do teeth whitening kits work?

You can place most teeth whitening kits into one of two categories: those that use whitening serum and those that use the LED light system. Here’s how both work:

  • Whitening serum

There are two types of these. Some whitening serums coat the teeth, giving them a whiter appearance. This is ok, but it’s more of a band-aid, not really dealing with the problem. The second, better serums, actually clean your teeth, making them shinier and healthier. These serums contain gentle but effective ingredients that break down the stains that have built up on your teeth over time. The best teeth whitening products will contain hydrogen peroxide because this effectively removes teeth stains for whiter smiles.

  • LED light systems

LED light system treatments utilize the power of LED lights to boost the efficacy of the whitening agent that’s already been applied. The system emits a cool light that activates the whitening gel, making it work even better than before.

The best teeth whitening products combine both of these technologies for optimal results.

Besides these kits, you can also find a wide variety of whitening products on the market, including teeth whitening strips and toothpaste. These teeth whitening methods are an even easier way to brighten your pearly whites at home and will save you the cost of a trip to the dentist for a full bleaching procedure. Strips also offer more of an instant teeth whitening solution, as opposed to products you'll need to use for months on end or regular trips to the dentist. 

Are teeth whitener kits a good option for sensitive teeth?

Some whitening gels use harsh, abrasive elements that bleach the teeth to remove stains. While this is an effective option, abrasive pastes can wreak havoc on a set of sensitive teeth. So that being said you may want to choose carefully for sensitive teeth whitening. Most teeth whitening kits will come with a disclaimer that very sensitive teeth may experience some discomfort. But you can take your cue from the majority of online reviews to see which services are better for sensitive teeth. Many of the products like the LED brushes now have settings for best teeth whitening for sensitive teeth. Now, companies are catering to users who are seeking sensitive teeth whitening.

How do I check if a teeth whitening kit is safe?

Most companies that base their treatments on LED light therapy use the same technology. So you are pretty much safe, though you should check if the company is certified or using certified technology (something you can see from the website or via customer service quickly).

On the other hand, the whitening serums vary from one company to the next. You need to check that the ingredients are safe both in terms of your general health and for the enamel on your teeth and if it's suitable for sensitive teeth whitening. You don’t want a whitening toothpaste that is so corrosive it wears away at your tooth’s enamel surface. That’ll only cause damage in the long run.

How much do teeth whitening kits cost?

How much depends on the type of system and where you’re holding in the whitening process. At-home teeth whitening kits are incredibly affordable, a fraction of the price you would pay if you invested in an in-clinic treatment. So that’s already good news. LED light systems are going to cost you more than simple whitening toothpaste. An LED light accelerator can range from $35 to up to several hundreds of dollars. But the majority will average around $150.

Meanwhile, whitening toothpaste is considerably cheaper, costing a few bucks a tube. And you can sign up for auto-deliveries so you enjoy a discounted price and never run out. Whitening strips run about the same rate and can offer a quick and easy solution, but the results won't last as long - you'll just have to decide if instant whitening is what you want or if long-term results are more your point. 

Why should you choose at-home teeth whitening kits?

At-home teeth whitening kits are quickly becoming the preferred option over in-clinic treatments. Here are a few reasons why these DIY teeth whitening kits will rock your world:

  • Costs: You’re literally paying a fraction of what you’d pay in-clinic for the same treatment. Whitening your teeth at the dentist's can cost you a pretty penny. 

  • Convenience: You don’t have to run around to a clinic, take time out of your day, or fit things into your schedule. At-home teeth whitening kits can be used wherever and whenever you want.

  • Efficacy and speed: The beauty of it all is that the best teeth whitening products use the exact same whitening agents as the ones the cosmetic dentists use in their clinics. So you are getting superb results without all the hassle. And since you’re doing it yourself at home, it’ll happen much faster.
