An Honest Review of Crest Scope All Day Mouthwash (2024 Edition)

During one of my usual trips to Walgreens, I stumbled upon a gem – Crest’s Scope All Day Mouthwash. What followed, however, was quite the misadventure when Walgreens discontinued stocking it, prompting a rather frantic quest to find it in other local stores.

While I’m sure many presume this is just a regular mouthwash, there’s a lot more to it than meets the eye. In this blog post, I will share my honest thoughts about this product, its pros and cons, and why it’s worth considering.

Active Ingredients and Features

This mouthwash’s main power comes from its active ingredient – Cetylpyridinium Chloride (CPC). Interestingly, research has found that CPC-based mouthwashes can be as effective as Chlorhexidine gluconate (CHX) mouthwashes in reducing dental plaque build-up and preventing gum inflammation, but with lesser side effects. This makes it an excellent supplemental tool for brushing.

Another ingredient in this mouthwash that’s worth mentioning is Zinc. Zinc in mouthwashes can prevent the creation of Volatile Sulfur Compounds (VSC), which contribute to bad breath.

There’s also Sucralose in this product, which I’m not particularly fond of. I should also mention that the product promises to provide 24+ hours of breath protection.

The complete list of ingredients includes:

  • Glycerin
  • Flavor
  • Zinc Lactate
  • Methylparaben
  • Sodium Saccharin
  • Sucralose
  • Propylparaben
  • Poloxamer 407
  • Water
  • Cetylpyridinium Chloride

Packaging and Size

The mouthwash comes in a robust 1L bottle. Though its considerable size may not bode well with people frequently on the move, it is certainly a win for those who enjoy value-for-volume purchases.


The bottle locks securely, preventing leakage and providing reassurance that the integrity of the solution inside will be maintained. Whether on your bathroom countertop or inside a packed suitcase, you won’t need to fret about unintended spills or leaks.

Crest has been refining their packaging design over time, and the recent version of the Crest Scope All Day Mouthwash introduces a company-branded printed seal. This new seal seals the deal for me, in terms of authenticity and safety guarantee—as compared to their previous plastic seal, which felt somewhat flimsy and less secure.

Taste, Flavors, and Mouthfeel

Moving onto flavor, this particular one is called Clean Mint. I’ve been a Crest user for a long time, but I’ve recently had to cut ties with their other formulas due to the slight irritation they caused around my mouth. Thankfully, transferring to this clear variant has resulted in no such problems. I find the flavor appealing and lingering.

One of the aspects I like is its clear color which helps prevent staining on my dental implants that are sometimes caused by blue or green mouthwashes.

It’s important to note that you should only use a small quantity, diluted with water to avoid excessive frothing in your mouth. Though it does a good job and is not overbearingly minty, there is a bitter aftertaste that can distort your taste buds for the first few hours post-use.

Use and Effectiveness

Following proper usage instructions of rinsing your mouth for 30 seconds with 4 teaspoons of the product twice a day after brushing and flossing gives great results. The active ingredients in this mouthwash deliver a clean mouth feeling that, in my experience, lasts for about two hours.


One valuable tip I discovered is incorporating it with my Waterpik treatment for an added cleaning boost. I found it particularly effective in controlling bad breath and saw a noticeable improvement in my oral health.

Price and Value

The 1L bottle is available for roughly $5, a price which I find is quite reasonable. The only catch is that it’s somewhat challenging to locate in stores. While a little of it goes a long way saving you money over time, I do wish there were more size options available, particularly travel-friendly ones.

Final Verdict

Despite the bitterness of the aftertaste and the absence of travel-friendly options, Crest Scope All Day mouthwash has become one of my go-to choices. The combination of active ingredients, refreshing flavor, and effectiveness compensates for these shortcomings. If you can overlook these minor drawbacks, I believe this product could prove to be a valuable addition to your oral care routine.
