10 Best Effective Teeth Whitening Kits to be Tried at Home

After years of abuse from smoking, coffee drinking, or sweets, your teeth are likely not shining and white. They’re not looking their best. If you plan on kicking your bad habits, you’ll want to whiten your smile. It could be for an event or just to feel your best. A white smile can give you confidence. Using an at-home whitening kit is an inexpensive way to get the same whitening you’d receive in your dentist’s office. In fact, some of the kits on this list are sold in dentist’s offices regularly.

To find the best whitening kit, you’ll need to consider the time you have for whitening as well as the sensitivity of your teeth. Many strips and gels have lower whitening agents to ensure that you won’t have pain, but they take longer to work. You’ll want to balance your sensitivity with the time of the results you need. In these reviews, there is information that will help you make a decision regarding your new white smile of the future.

What is a Teeth Whitening Kit?

To get a whiter smile, people often go to their dentist’s office. They would spend thousands of dollars to get a whiter smile. Now, there are teeth whitening options that can be done at home for a fraction of the price. They don’t have the same amount of peroxides or carbamides as in-office whitening. They are inexpensive, though, so it’s easy to purchase more applications.

Teeth whitening kits come in a variety of types. There are gels, pastes, and strips that can be used to whiten teeth. Each method has a certain amount of whitening agent. The whitening solution is left on the teeth to whiten the enamel. It’s called whitening or bleaching depending on the method used.

The whitening kit is used over time. It can take up to 14 applications to see a noticeable difference in the bleaching process. They’re used daily and left on for up to 60 minutes.

AuraGlow Teeth Whitening Kit

Key Features

5 LED Lights – Most LED lights for whitening come with one bulb. This light comes with 5 bulbs, so it’ll last a very long time. The included battery will last for up to 48 hours of use. The light doesn’t cause sensitivity, either. It’ll speed up the whitening, so you’ll see results quickly.

Built-In Timer – You don’t have to worry about timing the tray and gel. The light comes with a built-in timer that will beep. Every 10 minutes, you’ll get an alert beep that tells you time has passed. All you have to do is keep track of the beeps while doing other things.

Tray and Light Attached – The tray and the light are attached in this kit. It’s simple to squeeze the gel into the tray with the included syringes. The piece is one unit that doesn’t need to be held in place, either. It’ll give you a hands-free whitening that allows you to do other things while waiting.

Dental Grade Gel – The whitening gel uses 35% carbamide peroxide. It’s meant to deliver fast results without sensitivity. There’s enough gel in this kit for 20 treatments over 20 days. Only 0.5ml of gel needs to be used in the tray for each treatment.

Applicator Brush – If you’re worried about getting the whitening gel all over your gums, the brush is a perfect solution. Instead of pressing your teeth into a tray full of gel, you can brush the right amount of gel onto the teeth.

My Impression

This whitening kit has some unique features and benefits that you won’t see in some of the other whitening kits. First, there’s the custom tray. Many other trays are supposed to be one size fits all, but they don’t fit around the teeth. You can warm this one under hot water and push it around your teeth. It’ll mold to the crevices and edges of the teeth for a good fit.

There’s also a remineralization gel included with this whitening kit. The company wants to ensure that you’re whitening in a manner that doesn’t cause pain. Sensitivity can be a problem when whitening even if you’ve never had sensitive teeth before. The gel will stop you from getting pain. It’ll also help remove pain after whitening.

Lastly, the LED light for this whitening kit will speed up the whitening you’ll experience. That’s great if you have a certain event where you need whiter teeth. A wedding or school reunion are two important events where you’ll want a whiter smile. The LED light will help you whiten your teeth much faster than without it.

This whitening kit has advanced seal technology that will keep the film in place. Even if you’re talking or drinking water, the seal won’t be broken until you’re ready.

30-Minute Treatments – While the express strips are a one-hour treatment, the regular ones last for 30 minutes. You don’t need to wear strips on your teeth for an entire day or even a few hours to see results. After 3 days, you’ll be able to see your smile whitening.

Safe for Enamel – The whitening agent used in the strips is the same grade of whitening used at the dentist’s office. It’s gentle for enamel, yet, it will blast your teeth with whitening. It should be fine for sensitive teeth, too.

My Impression

It’s fantastic that this whitening kit has so many features going for it. You only need one box of strips to really see a difference in the whiteness of your smile. My favorite part of these strips from Crest is that they have two different kinds of strips in one box. As you’re whitening over the course of the 30 days, you might have an event where you need to boost the white of your smile quickly. The extra express strips are a great bonus.

The strips only need to stay on your teeth for 30 minutes to 1 hour. In that time, you will be able to talk easily without the strips slipping. The Advanced Seal Technology will mold to your teeth no matter what the shape of them. Once they’re in place, they’ll only move when you remove them.

It’ll only take a few days before you see a whiter smile. If you use the boosting express strips, that time can be cut in half. It’ll remove years of stains from your teeth. It’s important that you stop smoking or drinking coffee during the time you’re brightening your smile. You’ll see better results.

What Could be Better?

The seal technology can make the white strips hard to remove if you leave them on too long.

Opalescence Teeth Whitening Gel Mint

Key Features

Sensitive Formula – The gel has carbamide peroxide like many other whitening systems. This one also has potassium nitrate and fluoride. Fluoride added to your whitening agent will keep sensitivity down.

Gel for More Coverage – When you use a gel, you’re more able to whiten between the crevices in the teeth. If you have overlapping or crowded teeth, the gel will cover those areas. You won’t end up with teeth that are white with yellow spots on them.


Long Shelf Life – This gel whitening can be kept in the refrigerator to last for a longer amount of time. It’s meant to last for up to 18 months. This will allow you to boost your whitening every month to keep your smile bright and fresh.

Dentist Suggested – This is the same product that is recommended and sold at most dentist’s offices. It’s a product that they stand behind when suggesting it to their patients. You’re getting the same product at a fraction of the price when sold at the dentist’s office, too.

My Impression

The formula used for this at-home whitening kit is meant to keep your teeth and gums from becoming sensitive. It comes with fluoride, which is an ingredient that you would ask your dentist for when you have sensitivity to whitening gel. It’s likely why many dentists’ offices sell this brand to their patients.

The amount of gel in the syringes will cause this whitening kit to last for a long time. You could easily hit the end of the expiration date with a bunch of gel left over. Each tube can fill the trays approximately 5 times or more depending on the amount of gel used. You don’t need a ton of gel to fill the tray. If you use too much, it’ll leak onto your gums.

While you don’t have to mold the trays to your teeth, you might want to do that. The trays come in 3 sizes to make the process easier. You can certainly use them without molding, but molding will make the process easier. The tray will stay in your mouth longer and be more comfortable, too.

You can use this treatment each morning while you’re getting ready for work. You can even drink water while the strips are in place.

Leave the strips in place for one hour before applying the light. This will boost the whitening you experience with the strips. Most strips come with 20 days of treatments because they don’t include a light. The blue light treatment will get deeper into the enamel to remove yellow stains.

The whitening is deeper than with other white strips. In fact, the whitening is so deep that it lasts longer than most other whitening kits. You will only need to do a minimal amount of boosting over 36 months to keep your smile as white as possible. The light is what makes a huge difference in the process.

My Impression

This is a whitening kit that is suggested by many dentists in their office. It will whiten teeth with a combination of peroxide in the gel and blue-light from the included light source. The manufacturer recommends that you use the syringe and a cotton swab to dot each tooth. That will put the right amount of product on each tooth for whitening.

After adding the gel to each tooth, the tray will keep the gel from going everywhere. The light is added after some time is spent with the gel on your teeth. It’s meant to get deep once the gel has had time work on the enamel.

One of the best features of this whitening kit is that you don’t have to use it over 10 to 20 days in a row. Most whitening kits only work when you use them every single day. That isn’t the case with this kit. You can take a few days rest between whitening. You’ll still get great results.

Different Types of Whitening Kits for Teeth

There are different types of kits available which are very effective when it comes to teeth whitening. Let’s have a look at what those are:

  • Strips


With strip whitening kits, the bleaching agent adheres to the back of the plastic strip. The strip is placed over the front of the teeth. The dampness on the teeth from your saliva causes the whitening agent to be activated. Many strip whitening kits have a special formula that will keep the strip from slipping off the teeth.

  • Gel & Trays

Gel Trays

Some trays are crafted by a dentist, so they’ll mold to the teeth. For the most part, though, the gel and tray is purchased at the store. The gel is squeezed into the tray. The tray is placed over the teeth. The gel and tray method is a little messy unless you’re very careful.

  • LED light kit

LED light kit

Whitening agents can react to LED light and speed up the whitening process. A slow-acting bleaching agent like hydrogen peroxide will work faster when light is used as a catalyst. It speeds up the process, so instead of waiting weeks for whiter teeth, it can happen within a few applications.

Things to consider while buying a teeth whitening kit

When you intend to buy a teeth whitening kit, you should ask yourself a few things which will help you choose the best teeth whitening kit that best suits your needs. Try to keep the following factors in your mind as I go through them one by one.

  • The Right Type

You’ll need to decide what type will work best for your teeth. You could check with your dentist to ensure that your teeth are suitable for teeth whitening. He or she can also recommend whether you should use strips or a tray. If you have crowns or fillings, it could change the type of whitening kit you need.

  • Ease of Use

The whitening kit should be easy to use. If you don’t have a lot of time in the morning, you won’t want to purchase strips that have to be left alone for an hour or two. Tray and gel in your mouth overnight might be a better choice. If you have a big event coming in the near future, you will want to whiten your teeth faster. You can purchase an LED light with your whitening.

  • Sensitivity and Pain

The whitening product isn’t always the cause of sensitivity or tooth pain after whitening. Some people are sensitive to the peroxide. If you have sensitive teeth, you’ll want to make adjustments to the whitening routine. You can purchase a whitening kit with less peroxide in it. You can use whitening gel or strips for less time. Instead of leaving it on for 30 minutes, remove the whitening strips after 10 minutes.

  • The Taste

Whitening gel is never going to taste wonderful, but you can purchase strips or gel that are minty like toothpaste. Instead of tasting like peroxide, it’ll taste like mint. Most people understand that while it’s not a pleasant taste, it won’t stick around long after whitening. Simply rinse out your mouth.

  • Duration of the Treatment

If you want to whiten your teeth quickly, pick a treatment that will give you a whiter, brighter smile in less time. It should have more peroxide or other whitening agents. Many whitening kits advertise an average of 14 days of treatments before you’ll see a difference.

  • The Target

The person who wants whiter teeth might have braces or crowns that make it tough to find the right whitening kit. The target of tooth whitening will fixate that certain area with the right kit. For example, a person with yellowing, crowded teeth might need to use a gel and tray to get between each tooth for whitening purposes.

  • Authorized by Dental Associations

The best whitening kit will be approved and authorized by dental associations. Even if it’s not recommended specifically by associations, you can get recommendations from your own dentist. Your dentist has expertise to give a solid review of most of the products on the market today.

Using a Teeth Whitening Kit – Instructions and Guide

The type of whitening kit will influence the steps in using it. If you purchase whitening strips, the process will be different than if you used gel and a tray.

Whitening Strips Instructions

The sensitivity of your teeth will dictate some of the steps you’ll take for whitening. If you are prone to sensitive teeth, you shouldn’t brush directly before applying the strip. Give your teeth a chance to rest before applying the strip.

Once you’re ready to whiten, open the foil wrapper and remove the gel from the plastic backing. Press the whitening material to each tooth and in the creases between. You’ll want to ensure that the material has firm contact with each tooth. If you miss spots, those areas will not be whitened.

Keep the material on the suggested amount of time based on the product itself. The time indicated will differ between products based on their ingredients.

Gel and Tray Kit

A gel and tray kit is a bit messier than the whitening strips. They have benefits, though. The whitening agent can be stronger in the gel form of whitening. In some cases, it can be left on overnight, too.

The trays and gel come in the whitening kit. You’ll squeeze the gel into the trays and cover the teeth with the tray itself. Leave the tray in the mouth for the recommended amount of time.

Once it’s time to remove the tray, you can brush gently to remove the solution. It helps to rinse the gel from the mouth when you brush first. Use the trays and gel for the suggested number of days and times to get a whiter smile.

LED Light

The LED light can be purchased to be used with the gel whitening. It speeds up the process. Once the gel is placed on the teeth, the light is used to shine on the enamel. It removes deep stains and brightens your smile.

In some cases, the whitening LED light comes with a gel pen that is used to spread the whitening solution. The light will speed up the process significantly. It’s used for a few minutes each day to brighten your smile.

Warnings Regarding the Use of Teeth Whitening Kits

Teeth whitening doesn’t have a huge amount of side effects. There are certain things you should watch for when you’re using a bleaching solution on your teeth. Sensitivity is one of the biggest things you could possibly deal with when whitening. It doesn’t happen to everyone, but some people have pain after whitening. Other people have irritation to the gums after whitening. You can avoid problems in a few ways.

Instead of leaving the gel or strips on for a long time, you can do shorter sessions. For example, instead of one 60-minute session, you could split them into two t30-minute sessions. Wait a few days before attempting to whiten after you’ve had pain. It will give your teeth time to adjust to the whitening solution.

You could also visit your dentist and get his or her advice. Your dentist can give you a toothpaste or rinse that is high in fluoride. Toothpaste for sensitive teeth can also be used for a few days before trying to whiten again.

Dentist’s Point of View

It’s recommended that you see your dentist before beginning any whitening procedure. At that time, you can get a cleaning as well as a consultation about the specific issues you have with your teeth. As mentioned previously, the whitening agent won’t work on crowns and fillings.

While dentists lose money when people whiten at home, there’s no other reason they don’t recommend those kinds of procedures. They whiten teeth without any real side effects that can have an impact on your teeth. As long as they’re used properly and the person follows directions, the process is safe.

After bleaching, it’s vital that you stay away from any foods or beverages that will restain the teeth. Treatment shouldn’t happen every day for a very long time. That can lead to serious issues like over-bleaching and damage to the tooth enamel. You should stay away from things like smoking, drinking coffee, wine or tea, and eating foods that stain.

You can whiten with sensitive teeth, but you’ll have to prepare your teeth in advance. Use toothpaste made for sensitive teeth. Ask your dentist for a mouthwash or rinse with fluoride to protect the enamel. Preventative steps can be taken to avoid serious pain and sensitivity.

Can whitening kits be used with crowns or veneers?
Whitening can be done on other teeth. Crowns or veneers are not organic teeth. They’re porcelain, ceramic, or other materials that won’t react in the same way to bleaching agents.

How much whitening agent should be in the whitening kit?
The amount of whitening agent will depend on the brand. It will also depend on how long you’re leaving it on your teeth. If you want a gel you can wear overnight, it’ll have less hydrogen peroxide and more carbamide peroxide.

Can whitening kits be used with braces?
Whitening kits can be used with braces, but there will have to be some accommodations made. If you have metal brackets on the teeth, you can use a gel that will get behind the teeth. You don’t have to wait years for your braces to come off to see whitening. On the other hand, you might want to wait to whiten your teeth until the brackets are removed. A good whitening agent will make the teeth much whiter, and behind the brackets won’t get the same effect.

Are LED lights effective for whitening?
LED lights are very important for whitening quickly and efficiently. While whitening will happen without the light, fast whitening is possible with the light. It activates the peroxide and enhances the impact of it.

How often can you use a whitening kit?
Most whitening kits have 14 days of treatments. After 14 days, you’ll want to evaluate the whiteness of your smile. If your teeth aren’t as white as you’d like, you’ll want to consider other factors. You don’t want to continue using a whitening agent every day indefinitely. See your dentist if you’re not getting the whitest smile possible. You could be doing something wrong.
