Crest Whitestrips vs GLO Teeth Whitening: The Comparison

A bright smile has an undeniable effect on our overall appearance. So if you’re looking for a quick confidence boost, you may want to consider teeth whitening. There are plenty of affordable and accessible at-home whitening solutions available, but which one is right for you? To help you find the best fit for you, we’re going to break down the pros and cons of two of the most popular at-home whitening methods: the GLO Teeth Whitening System and Crest Whitestrips.

How Crest Whitestrips Work vs How GLO Works

Crest Whitestrips

Crest Whitestrips are thin, adhesive strips affixed with whitening gel. Strips are placed on teeth and will cling to teeth, allowing the whitening gel to work on teeth. Crest White strips come in many different varieties: such as Crest 3D Whitestrips, Crest Supreme Whitestrips, and Crest 3D White Professional Effect Whitestrips, which range in price and efficacy.

GLO Teeth Whitening Device

The GLO Teeth Whitening Device is a professional-grade whitening system that’s easy to use from the comfort of your own home. A specially formulated hydrogen peroxide gel whitens teeth without causing pain or sensitivity. The GLO (Guided Light Optics) mouthpiece emits gentle heat and light, accelerating the whitening process. The GLO whitening system delivers unparalleled whitening results and is enamel-safe and even okay to use on crowns, bridges, and veneers.


How to Put on Crest 3D Whitestrips

Should I brush before using Crest Whitestrips?
Many users question if they should brush before or after using Crest Whitestrips. Yes. When using, begin with a clean smile. Brush teeth thoroughly before using Crest Whitestrips to clear away any debris or plaque and allow the whitening gel to penetrate the enamel.

How do I apply Crest Whitestrips?
To apply Crest Whitestrips, peel the flexible whitening strip off of the plastic film backing. Next, apply the sticky side of the strip to the front of teeth, smoothing to adhere teeth and smooth down along the backside of the teeth until teeth are covered.

How long do I wear Crest Whitestrips?
Crest Whitestrips come in many varieties with application times that vary from 30 minutes to 1 hour. Be sure to check the instructions for your Crest Whitestrips to apply for the correct amount of time. Leaving Whitestrips on for too long may cause excess sensitivity and tooth or gum damage.

Should I brush my teeth after using Crest Whitestrips?
It’s not necessary to brush after using Crest Whitestrips, as the whitening gel should dissolve with use. However, some users find it helpful to rinse with water to entirely remove whitening gel and reduce tooth damage and sensitivity from extended gel use.

Can I drink after using Crest Whitestrips?
It is okay to eat and drink immediately after using your Crest Whitestrips. However, be sure not to eat or drink while Crest Whitestrips are applied, as this can mitigate your whitening results and cause the strips to slip off teeth.

How do I use the GLO Teeth Whitening Device?

  • Begin with a fully charged GLO Teeth Whitening device. Use the included charging cord to charge your device. When charging, your device will blink and emit a continuous blue light when fully charged and ready to use.
  • Each GLO Whitening system comes with a soothing lip moisturizer. When you are ready to begin your whitening routine, apply lip moisturizer to the inside and outside of lips to soothe, moisturize, and protect lips.
  • Open one of the pre-measured, ready-to-use GLO Whitening Gel Vials by twisting off the cap. Squeeze out the whitening gel and brush onto the front of the teeth only. Each gel vial has enough whitening gel for an entire GLO session. Each GLO session is 32 minutes long, broken down into 4-8 minute whitening blocks.
  • After applying the whitening gel, place the mouthpiece on your teeth and relax your jaw to close your mouth around the mouthpiece. Next, turn on your whitening device. It will emit blue light and begin to warm to a mild temperature that accelerates whitening results. Your GLO whitening device will time your whitening session - no need to set a timer! The device will remain on for 8 minutes and then blink when the whitening time block is coming to a close.
  • When the light turns off, remove the mouthpiece and reapply whitening gel to your teeth. You may also reapply lip moisturizer to lips for added comfort and protection. Then, place the mouthpiece back in the mouth and repeat the process three more times, for 4-8 minute applications totaling 32 minutes.

How long should I use my GLO Teeth Whitening Device?

Sensitive Teeth

Crest Whitestrips and Sensitive Teeth

Crest Whitestrips are designed to be safe for use at home, but you should carefully follow the directions on the box for optimal results. Tooth sensitivity and pain have been associated with Crest Whitestrips, and some users report having painful or numb white spots on the gums after using Crest Whitestrips. To lessen the risk of developing sensitivity, pain, or spots, apply only on teeth, avoid the gum line when applying Whitestrips, and remove carefully after the allotted whitening time.

GLO Device and Sensitive Teeth

GLO Teeth Whitening Devices and GLO Teeth Whitening Gel Vials are enamel safe and don’t cause sensitivity or pain. The GLO Whitening Gel is dentist formulated and contains hydrogen peroxide that will not harm teeth and is safe to use even on bridges, crowns, and veneers. The GLO Whitening Device is safe to use often. Simply use until you reach your desired whiteness!

Teeth Whitening Coverage

Whitestrips Coverage

Crest Whitestrips come in a ‘one-size-fits-all’ strip. The flexible strips adhere to teeth and mainly cover the front teeth that are exposed when smiling. However, crest Whitestrips don’t reach molars and may not cover all of your smile if your teeth are large or if your smile is more expansive than average. Additionally, Crest Whitestrips may shift during use, leaving some teeth uncovered and creating an uneven whitening effect.

On the other end of the spectrum, many users find that Crest Whitestrips come into contact with sensitive gum tissue, causing white spots on gums that can be irritated, numb, or painful.

GLO Teeth Coverage

The GLO Teeth Whitening Device mouthpiece is dentist invented and ergonomically designed to fit perfectly around your teeth while remaining comfortable. The mouthpiece securely fits onto teeth, ensuring a consistent whitening experience and reaching further around your smile to whiten even more of your teeth. The specially formulated GLO Teeth Whitening Vials are easy to apply and ensure a tailored whitening experience. When you brush on the hydrogen peroxide whitening gel, you can avoid gums and apply the whitening gel on all of the exposed teeth when you smile.

How Long Does Whitening Take?

How Long Does Crest Whitestrips Take to Work?

Crest Whitestrips should be applied from 30 minutes to 1 hour twice a day, totaling a whitening time of 1 hour to 2 hours a day depending on the type you are using. Be sure to check your box for specific directions. It is unlikely you will see a significant change in the appearance of your smile after one use of Crest Whitestrips. According to Crest, it takes 3+ days of twice-a-day use to see whitening results, and noticeable whitening results should appear by two weeks of consistent twice-a-day use.

How Long Does GLO Take to Whiten Teeth?

GLO Teeth Whitening Devices deliver brighter, whiter teeth in just one 32-minute GLO session, making GLO the fastest way to whiten your teeth from home. In addition, GLO Whitening Systems are safe to use until you reach desired results. Most users find that their smile is noticeably whiter after just one use of GLO Teeth Whitening Device, and they can use it a few times a week to boost whitening results as needed.

On-the-Go Portability

Crest Whitestrips are compact and individually wrapped, making them very travel-friendly. Simply pack as many Whitestrips as you’ll need on your trip, typically two sets of strips for each day that you’re traveling. The GLO Science Teeth Whitening System is also excellent for travel. It comes with a handy travel case with plenty of room to hold your mouthpiece and control, a charging cable, lip moisturizer, and pre-measured GLO Teeth Whitening Gel Vials.
