At Home, Teeth Whitening Kits Can Significantly Whiten Some People’s Teeth

Most of us have to spend hours at the dentist each year to have coffee stains scrubbed from our teeth, with the help of those scary looking scrapers and machines that seem like they are removing half the enamel.

It, therefore, seems hard to believe that simply applying some products from a kit at home would be able to make your teeth sparkle.

In reality, many teeth whitening kits for home use do actually work.

However, they do not work 100% effectively for everyone, and not on every type of stain or discoloration.

The first step in searching for an effective teeth whitening product is to understand what the kits are good for, and when they are no more effective than brushing.

Importantly, teeth whitening is not a substitute for normal tooth care and hygiene, which should include brushing twice a day with a top of the range electric toothbrush.

In fact, whitening could be a very bad idea if the last time you saw the dentist was when your parents dragged you there; the bleach and other solutions used in the kits can get inside cavities and hurt – a lot.

If your teeth are in relatively good shape, you can consider whitening. However, there are two different types of tooth stain or discoloration and each calls for a different approach.

– Extrinsic stains, the surface stains that the dentist often scrubs away, are caused by coffee, tea, smoking, red wine and foods that naturally cause stains (for example, spaghetti sauce). A whitening toothpaste, mouth rinse or whitening strips may take care of most extrinsic stains in between dental check-ups.

– Alternatively, intrinsic stains are deeper discolorations that build up inside the enamel, possibly due to aging, genetics or medications. Abrasive whitening pastes or bleaching may be necessary to remove these stains. In some cases, only dentist supervised whitening programs will be effective.

There are many different types of teeth whitening products on the market according to the stain you wish to remove.

The majority of whitening kits are targeted towards extrinsic stains, although there are some kits that can tackle intrinsic stains as well.

Let’s polish up that smile, and review the top 5 best at home teeth whitening kits!

1. Crest 3D White Professional Effects Whitestrips Teeth Whitening Kit

The most popular products for putting a shine back onto teeth are whitening strips, and Crest dominates the market. That is not only due to the familiar brand name, but because Crest strips do the best job.

There are several different Crest whitening strips on the market, with the 3D Professional Effects strips producing the most professional results while being easy to use.

Each package comes with 40 whitening strips, to be used for a total of 20 days (one strip for the upper teeth and one for the lower). You peel a strip from its backing, just like a Band-Aid, and press it onto your teeth.

The whitening gel on the back of the strip is moisture-activated, so it sticks to the teeth firmly until you remove it. You cannot talk or even drink water while wearing the 3D strips. After 30 minutes, you remove the strips. The best time to use them is in the morning, before brushing your teeth.

There are several ingredients in the whitening gel, but most are there to prevent the strips from falling off teeth, keeping the strips together and making them taste decent. The primary active ingredient in the strips is hydrogen peroxide, which is in mouthwashes and is safe to use.

It is one of the main ingredients in the gels that dentists use for expensive teeth whitening treatments. The strips themselves are made from polyethylene which will not do any harm if accidentally swallowed.

The 3D strips do a remarkable job. You should start to see some noticeable whitening after 3-4 days; after the full 20-day treatment period most people’s teeth are a full two shades whiter. The strips are able to remove intrinsic stains that are below the surface of the tooth’s enamel.

Crest claims that the 3D Professional teeth whitening kit can remove “14 years” worth of stains. The only negative is that some people with very sensitive teeth may feel some discomfort or pain when the strips are applied; we’ll have a product for them later on.

Dental office whitening treatments can cost anywhere from a few hundred dollars for take-home whitening trays, to more than $1000 for full-scale laser treatment. For that investment, you could buy lots of Crest 3D Professional Effects kits – which do you think makes sense to try first?

Facts and figures on the Crest 3D White Professional Effects Whitestrips Teeth Whitening Kit:

  • Style: Strips
  • Kit: 40 strips
  • Usage: 30 minutes per day
  • Course of treatment: 20 days
  • Active Ingredient: Hydrogen peroxide

2. Rembrandt 2-Hour Whitening Kit

Crest 3D Professional Whitestrips are best for putting a new smile on your face over the course of a few weeks. But what if you have an important job interview tomorrow, or you are going out tonight to meet that hot girl or guy you found on Tinder, and want to look your best?

Then the Rembrandt 2-Hour teeth whitening kit is the one for you. Rembrandt was the first company to specialize in teeth whitening products, and they know what they are doing.

Realistically, you are not going to be able to experience the best result with this kit if you start using it at 6 pm when your date is at 8 pm! That is because the “2-Hour” label on the product is a bit misleading; you need a little extra time to get everything ready.

The kit comes with “comfytray applicators,” which you fill with gel. In order to use the applicators, you first have to mold them to your teeth shape by dipping them into hot water. You then fill the applicators with a small amount of gel and fit them onto your teeth. It helps to put Vaseline on your lips to protect them from dripping gel, and to use a Q-tip to remove the extra gel from your gums.

The applicator trays stay on for 20 minutes, then you take them off to rest for 10 minutes, put them back on for another 20 minutes. You repeat this pattern until two hours is complete. The kits contains four 20-minute applications, which is sufficient for two-hour sessions with four 10-minute rest periods.

Similar to Crest strips, Rembrandt uses hydrogen peroxide in their whitening kit. In addition, the kits contains potassium hydroxide, which is a harsher chemical used to bleach teeth, hence how this product is able to make teeth noticeably whiter in just a couple of hours.

The downside is that the chemicals can cause a mild burning sensation during use, which can be painful. To minimize any pain, use sensitive toothpaste like Sensodyne for a couple of weeks prior to using the kit, take some ibuprofen just before use, and apply Vaseline and Q-tips as mentioned earlier.

The bottom line, though, is that the Rembrandt 2-Hour kit works. No, your teeth won’t look as white as those on a beauty pageant contestant, but they’ll get much brighter and the effect will last as long as six months. They are also very reasonably priced.

Facts and figures on the Rembrandt 2-Hour Whitening Kit:

  • Style: Applicators
  • Kit: Two applicators, two tubes of gel
  • Usage: Four 20-minute applications
  • Course of treatment: Two hours (plus prep time)
  • Active Ingredients: Hydrogen peroxide, potassium hydroxide

3. GLO Science Brilliant Personal Teeth Whitening Device

When you visit the dentist for teeth whitening treatments, there is a good chance the process will involve gel trays and light-activated devices. That is what the GLO Science kit does but in the comfort of your own home.

The teeth whitening device is initially a little cumbersome to use, but you adapt to it quickly. First, you apply the lip balm supplied in the kit, then place a thin layer of the whitening gel onto the front of your teeth with the included brush.

Turn on the mouthpiece, put it into your mouth and clamp down on it as you would on a sports mouth guard until the lights on the device turn off eight minutes later.

The heat and LED light inside the mouthpiece “accelerate” the whitening action of the hydrogen peroxide that is contained in the gel. Repeat this procedure four times a day for five days; you can do all four daily treatments straight in a row (after rinsing your mouth and the mouth piece), or you can space them throughout the day.

The mouth piece in the kit is attached to the charger, so you cannot move around during treatments as you can with manual whitening kits. It is also not as comfortable as wearing thin strips on your teeth.

Compared to the 3D strips, the length of the treatment is definitely a plus (5 days versus 20 days), with the final whitening effect almost similar. Unfortunately, the price tag is not the same. That is why we ranked it at #3 on our list of the top 5 best teeth whitening kits.

Facts and figures on the GLO Science Brilliant Personal Teeth Whitening Device:

  • Style: Powered applicator
  • Kit: Applicator, ten tubes of gel, power adapter, charging dock, USB cable
  • Usage: Four eight-minute applications per day
  • Course of treatment: 3-5 days
  • Active Ingredient: Hydrogen peroxide

4. Shine Whitening Zero Peroxide Teeth Whitening System

Groom+Style mentioned earlier that we would suggest a whitening kit that is suitable for those with very sensitive teeth, and here it is. The Shine Whitening system uses botanical ingredients instead of hydrogen peroxide or other caustic chemicals, as well as LED light, to accelerate the whitening process.

The process of using this product is similar to the GLO Science kit, with a gel that goes into trays that then fit into your mouth. However, the LED light in this kit is not built into the mouthpiece, so you have to insert it separately once the applicators are in place.

Unfortunately, this makes it a bit difficult to use. In spite of this, the system does work. You use the product twice a day for 15 minutes, and after a few weeks, most people see their teeth get one-to-two shades lighter.

Shine Whitening is not as effective as Crest 3D strips or the GLO Science kit, but it does not hurt, even if you have very sensitive teeth. For those who have not been able to use the more effective whitening products this is a great product.

Facts and figures on the Shine Whitening Zero Peroxide Teeth Whitening System:

  • Style: Applicator with separate LED light
  • Kit: Applicator, two tubes of gel, LED light
  • Usage: Two 15-minute applications, twice per day
  • Course of treatment: 30 days
  • Active Ingredients: Sodium bicarbonate, potassium sorbate, sodium fluoride, aloe and chamomile extracts

5. Moyeni Just Pure White Teeth Whitening Pen Kit

The Groom+Style Team was not quite sure whether this item qualifies as a kit, but it does much the same thing as the other products on our list, and it is a lot more convenient to use!

The gel inside the whitening pen is made from all-natural ingredients with no peroxide, so there is no pain for those with sensitive teeth.

Simply, you paint the gel onto your teeth, let it sit for 20 minutes, and then rinse and brush. There is no prescribed length of treatment; you can use it daily or once a week.

Over time your teeth brighten– if you use it daily, of course, the process will be more rapid. We do not think this product is as effective as the kits ranked above it, but they are all designed for specific time lengths while the benefit of the Just Pure White pen is convenience more than speed.

The pen is definitely worth considering if you do not want to bother with trays, strips, and gel.

Facts and figures on the Moyeni Just Pure White Teeth Whitening Pen Kit:

  • Style: Pen
  • Kit: Pen applicator
  • Usage: 20-minute applications
  • Course of treatment: Not defined
  • Active Ingredients: Sodium bicarbonate, sodium fluoride, aloe vera, pomegranate, chamomile
