1. Are teeth whitening kits easy to use?

Yes! There are many different types of whitening treatments, and some are easier than others. For example, many people find the standard whitening strips difficult to work with. These require you to put the whitening strips on your teeth, leave them there, and then peel them off. Consumers don’t like them because you have to position them just right, peel them off—it’s just messy. For this reason     , many folks prefer whitening toothpaste because it’s as easy as brushing your teeth. Of course, there’s also the LED light therapy. If you can bite down on a mouthpiece, you’ve got this in a bag.

2. Is LED teeth whitening treatment safe?

Yes, this type of treatment is completely safe. The LED light therapy used for teeth whitening administers a harmless blue light to activate the hydrogen peroxide or other whitening agents in the gel, removing deep staining on the teeth. However people with sensitive teeth may experience slight pain from using these products.

3.  How do I use my teeth whitening kit?

Whitening toothpastes and gels can be applied to your teeth just like regular toothpaste.

On the other hand, LED light-partnered gels should be applied gently to the teeth close to the gum line. Then insert your mouthpiece and turn on the device. After treatment is over, you may be required to rinse your mouth and rinse off the mouthpiece before storing it for future treatments.

Reviewing the Top Teeth Whitening Kits: Our Methodology Teeth Whitening Kit reviews are based on objective facts.  Our reviews are based on research via the Teeth Whitening Kit site, trusted 3rd party sites, customer reviews, and use of the product through free trials, or through paid use in some cases.

It is not always possible to use the product through its entire lifecycle, however, our reviewers do try the signup process, make customer service queries to check response times and perform any other possible function within the review period. For the rest of the information, we rely on what the brand says about its own product offering, customer reviews, and complaints, ratings from independent agencies like the Better Business Bureau, and trusted journalistic publications.

Some of the key features we compared when looking at the Teeth Whitening Kits on our list were:

-        Length and convenience of treatment (how long and difficult is the treatment itself)

-        Length of time results last for (how long your teeth will stay white for)

-        Price of kit (and refills if applicable)

-        Money-back guarantee or product warranty (if you’re not happy with the results)

-        Type of treatment used to achieve the results (LED or whitening serum)

What You Need to Know Before Choosing a Teeth Whitening Kit

There are several options when it comes to teeth whitening kits. So you might want to narrow down your choices. Here are a few questions you should ask to help in the process:

How long will it take to see results from this treatment?

Most at-home kits don’t take long to start working. In fact, the best teeth whitening products will start to show results after just one use. Most kits say it takes from 1 week to a month to show full results but that you’ll see improvements much earlier than that. Find out how long the brand says results will take to appear, how long you’ll need to use the system for each day, and how long results last.

What types of stains can teeth whitening remove?

Teeth whitening treatments can break down various types of stains including those from coffee, tea, red wines, dark sauces, and even some foods like blackberries. Yellowing caused by aging may also be brightened depending on the product. Black teeth cannot be reversed with this process.

How much is this going to cost me?

And of course, find out how much the system costs so you can do a price comparison.

What Types of Teeth Whitening Kits Are There?

There are basically two schools of thought when it comes to how to whiten teeth: cleansing pastes and LED light therapy. Let’s take a brief look at both of them.

-        Whitening gels and pastes

Teeth whitening kits that use whitening gels and toothpastes are designed to give your teeth a deep clean, removing the stains that have built up over time and clearing away harmful bacteria that causes tooth decay and yellowing.

-        LED light therapy

This type of teeth whitening treatment uses tiny, harmless LED lights to activate the whitening agent that is already on the teeth. Since the whitening toothpaste stops working after a certain number of hours, the LED light maximizes the whitener’s efficacy by making it work harder during that window of time.

Of course, the best teeth whitening kits use a combination of both for jet-powered results.

Whitening Teeth in the Midst of COVID-19

At-home teeth whitening kits are particularly relevant currently with the  widespread corona pandemic. With nationwide restrictions, self-isolation practices, and fears of catching the bug, one area that has seriously been neglected is oral hygiene. S But this is how harmful and unattractive yellow stains start to build up on your pearly whites. To keep your smile shining bright, a simple at-home teeth whitening kit will do the trick wonderfully.

Are Teeth Whitening Kits Safe?

That’s a tricky question. And the answer very much depends on the brand, product, and treatment itself.

In this industry, you also need to be sure that the technology and ingredients used in the treatment are safe.Certain whitening agents can be harmful to the enamel on your teeth. For example Alumina is known to be abrasive and can wear away at your protective enamel. Hydrogen peroxide and baking soda on the other hand are completely safe. Brands that you can trust will use these safe ingredients. .

Tips on Teeth Whitening Kits

Regardless of which teeth whitening products you use, here are a few tips to get the most out of your whitening sessions:

-        Actually do the treatment

The majority of the teeth whitening kits out there take somewhere between five and ten minutes a day. If you can’t spare that much time to have a mouthpiece on, you’re spreading yourself too thin, love.

Follow the steps. Finish the treatment. See the results.

-        Use the color chart

Seeing results is very rewarding. The best teeth whitening kits come with a color chart that lets you mark off where your teeth started on a color scale. Then you can chart your progress and see how far your pearly whites have come. Be proud!

-        Take advantage of whitening pens for touch-ups

You don’t need an entire whitening treatment once you’ve completed the treatment.. Generally, you’ll only need touch ups after that. So use whitening pens for spot whitening here and there to save money.

-        Do your research

Don’t leave your beautiful smile to chance. Make sure you read reviews, compare features, and get info on the products you’re putting in your mouth. Check out ingredients, learn about the whitening agents. Be informed because knowledge is power!

Also, don’t wait till the last minute. If you have a special event you want to have a beautiful smile for, order your whitening kit in advance. Truth is most kits can make a difference after your first application.

How Much Do Teeth Whitening Kits Cost

Teeth whitening kits can cost anywhere from $8 to up to around $500, . A simple whitening toothpaste will run you a few dollars because it’s basic yet effective at whitening.

Teeth whitening kits with LED light therapy are more expensive since you’re paying for the LED device itself. The top-end devices can cost up to $700, but you can find great quality  LED teeth whitening kits for $150.
