Listerine Original Antiseptic Mouthwash Review

(From $0.13 Best)

The Listerine-brand mouthwash does the job, and then some. Most users can't help but mention the unpleasant taste of the Original formula but the American Dental Association has given it a coveted Seal of Acceptance. For those who aren't faint of heart, the payoff is worth any short-term suffering.

A veteran on the mouthwash scene -- its roots go back to the late 19th century when it debuted as an antiseptic for surgical procedures -- Listerine Original Antiseptic (starting at $0.13/oz., Amazon) boasts a bracing formula that engenders a love-hate response from users, according to reviews. While the taste is described by some as horrible and nasty, Listerine Original Antiseptic reviews at Amazon laud its effectiveness in killing germs and quelling bad breath. In Listerine Original Antiseptic reviews at Drugstore.com consumers also report alternative uses for this inexpensive mouth rinse, such as gargling to soothe a sore throat and helping to heal the minor sores that come from biting your tongue or mouth. While many users like the no-frills, in-your-face approach that doesn't hide behind sweeteners, some report a peculiar, lingering aftertaste.

User reaction to the milder Cool Mint version veers more towards love than hate. One post at Walgreens claims the anticipation of swishing is enough to get him out of bed in the morning and other Listerine reviews of this version note how clean and fresh their mouths feel and how long the effect lasts.

The line of Listerine Antiseptic products, which includes Original, Cool Mint, FreshBurst, and Soft Mint, bears a seal of acceptance from the American Dental Association stating that they help prevent and reduce gingivitis and plaque, as the labels proclaim. Listerine Antiseptic is made of a simple yet powerful formula with four active ingredients: menthol, thymol, methyl salicylate, and eucalyptol, which, aided by a strong dose of alcohol (26.9 percent in the Original formulation and 21. 6 percent in the other three), kills millions of germs.

For anyone who just can't tolerate the short-term sting, Listerine also markets different, milder formulations. But it's the Original Antiseptic (or one of its siblings) that's hard to beat for lasting results.

Scope Original Mint Mouthwash Review

(From $0.10 Good)

Users describe Scope as pleasant, tingly, without a medicinal taste, and kid-friendly. Still, many of these same users claim Scope lacks the staying power of the Listerine and Act brands.

Scope Original Mint (starting at $0.10/oz., Amazon) is a bad-breath beater pure and simple, and reviews assert it does that adequately. Users who posted Scope Original Mint reviews at Amazon say they actually like the taste, especially when stacked against other mouthwashes, and one says the bubbles that result from swishing are most refreshing. Whereas some oral rinses are adult-only affairs, reviewers note that Scope Original Mint appeals to the whole family. Some posts at sites like Viewpoints, however, contend that the effect doesn't last all that long but add that it's a good buy nonetheless owing to its value price and light, minty taste.

Scope Original Mint contains alcohol -- 15 percent, by weight -- and a variety of other chemical ingredients, as well as blue and yellow dyes. It is one component in a line of Scope mouth rinse products that also includes Outlast and Dual-Blast formulations, each available in more than one flavor. Scope is produced by Crest, best known for its toothpastes.

Anyone looking for a quick fix will find nothing objectionable about Scope Original Mint. But keep the bottle handy in the event that it wears off before the appointed hour.

Act Total Care Anti-Cavity Fluoride Mouthwash Review

(From $0.18 Good)

This mouthwash is the go-to rinse for people who prefer a lighter taste and an alcohol-free product, especially if they want to swish with the kids. Act is also recommended by many dentists.

Overall, this concoction finds favor with users for its good taste (fresh mint) and alcohol-free ingredients list, according to Act Total Care Anti-Cavity Fluoride Mouthwash reviews. At sites like Walmart and Amazon users comment on the absence of any burning sensation, which they attribute to the absence of alcohol, and describe it as far more pleasant in the mouth than the high-powered competition. Many Act Total Care Anti-Cavity Fluoride Mouthwash reviews also note that the product is recommended by a dentist, and one user happily reports no cavities during the eight years he's been rinsing with it. Reviewers also like the fluoride formula and say this oral rinse makes their mouths and breath feel fresh and clean. One drawback of Act, given its fluoride component, is the necessity of waiting 30 minutes following use before eating or drinking.

Act Total Care Anti-Cavity Fluoride Mouthwash (starting at $0.18/oz., Amazon) comes in 18-ounce and 33-ounce sizes. The smaller bottle is formulated for once-a-day use and the larger bottle, with half the fluoride, is recommended for twice-daily swishing. The active ingredient in this rinse, as suggested by its name, is sodium fluoride, which is considered a key weapon in the fight against tooth decay. The Act Total Care line also includes a version for dry mouth and one with alcohol, Icy Clean Mint, which the company says is even better at defeating bad breath. Other Act mouth rinses present different formulations -- for instance, Sensitive, Restoring, and one for kids.

With a good dose of fluoride in each swish (the maximum amount allowed by law without a prescription), no alcohol, and a mild taste, Act Total Care Anti-Cavity Fluoride mouthwash is painless enough to work into a daily oral hygiene routine.

Crest Pro-Health Multi-Protection Oral Rinse Review

(From $0.20 Think Twice)

This mouthwash lays claim to all the right goals, and its alcohol-free formula appeals to many, but users report a raft of unpleasant side effects, such as brown stains on their teeth.

Crest Pro-Health Multi-Protection Oral Rinse (starting at $0.20/oz., Amazon) contains no alcohol, and some reviews regard this as a welcome change from other mouthwash formulas. Posts at Amazon and Walgreens note the absence of any burning sensation, the pleasing mouth feel and mint taste, and the positive effect on bad breath. But a convincing proportion of Crest Pro-Health Multi-Protection reviews ding the product, citing irritants such as brown stains on teeth, particularly the bottom row, sore gums, and coagulated residue from swishing. Reviewers also gripe about an aftertaste that lingers and seriously interferes with the taste of food.

The active ingredient in Crest Pro-Health Multi-Protection is CPC (cetylpyridinium chloride), a bacteria-fighting agent. Crest claims this rinse helps defend against the usual oral-hygiene villains -- bad breath, plaque, and gingivitis. Pro-Health Multi-Protection comes in two flavors, cool wintergreen or clear mint, and also in a night rinse version. The extended Pro-Health line includes Complete Rinse and Invigorating Clean mouthwashes.

Although Crest Pro-Health Multi-Protection has its fans, in part due to the alcohol-free formula, the proportion of negative reviews highlighting its flaws is enough to push the search for a cheap mouthwash in other directions.

Buying Guide

Why do you buy cheap mouthwash? To combat gingivitis, periodontitis, calculus, xerostomia? Or perhaps, like most of us, the primary motivation is straightforward: to get rid of bad breath. At the very least, the best cheap mouthwash provides a cosmetic solution -- it kills some bacteria and reduces bad breath, leaves a fresh taste in your mouth, and loosens food particles -- that gives you confidence to get in close and personal with loved ones and to interact with friends and colleagues.

Cheap Mouthwash Buying Guide

There are a slew of options available in the cheap mouthwash segment. Our top pick is Listerine Original Antiseptic (starting at $0.13/oz.), which packs a powerful and lasting punch even as some users groan about the bracing taste. (The milder Listerine Cool Mint Antiseptic is an equal in nearly all respects but decidedly more palatable.) Our second-tier picks include Act Total Care Anti-Cavity Fluoride Mouthwash (starting at $0.18/oz.), another cheap and well-regarded rinse that addresses both cosmetic and minor dental health issues, and Scope Original Mint (starting at $0.10/oz.), which garners a tepid response from users for its seemingly short-term impact but pleases many with its fresh, tingling taste. One cheap mouth rinse that doesn't rise to the occasion is Crest Pro-Health Multi-Protection Oral Rinse (starting at $0.20/oz.) for what users assert are disagreeable side effects like brown teeth stains and a long-lasting aftertaste.

Mouthwash can be divided into two categories: cosmetic, which dentists consider little more than a band-aid for bad breath, and therapeutic, which target serious conditions like tooth decay, gum disease, and dry mouth and more common problems like plaque, cavities, and tartar. Some mouthwashes are both cosmetic and therapeutic; Act's Anticavity line (a close relation of Act Total Care products), for example. Therapeutic rinses are regulated by the Food and Drug Administration, available with and without a prescription (depending on the product), and cost considerably more than cheap mouthwash, sometimes as much as $0.85/oz. The American Dental Association awards a Seal of Acceptance to products that have been independently evaluated for the safety of their ingredients and the veracity of their claims to effectiveness; among our picks, Listerine Antiseptic mouthwashes pass the test.

If the cost and/or formula of store-bought mouthwashes are not to your liking, numerous recipes for homemade mouthwash are scattered across the blogosphere. The cheapest of all the options we researched, DIY brews are made with the likes of herbs (myrrh, calendula, goldenseal), aloe vera, witch hazel, peppermint oil, tea tree oil, plantain leaf, baking soda, filtered water, vodka, and so on (but not all at once!) and cost less than pennies an ounce. Moreover, you know exactly what's in the rinse and can avoid the chemicals, sweeteners, and dyes found in commercial mouthwash, such as cetylpyridinium chloride, domiphen bromide, propylene glycol, sodium saccharin, sucralose, and blue 1.

You could also opt for commercially-produced natural mouthwashes, like Tom's of Maine Cleansing Mouthwash (starting at $0.29/oz.), which cost more than cheap mouthwash but shun synthetic flavors, preservatives, and colors, not to mention animal-derived ingredients.

Before committing to a mouth rinse, speak with a dentist. Mouthwash may mask the evidence of dental or other health problems, so dealing with underlying issues is critical. Even the best cheap mouthwash won't have the desired effect if the root of the bad breath problem is unrelated to having eaten garlic or raw onion. Investing in a therapeutic mouthwash that combats a given set of dental problems will cost more, but it could generate long-term savings by minimizing the need for expensive procedures down the road while simultaneously attacking opportunistic oral hygiene needs.

Still, the best cheap mouthwashes have their place in the medicine cabinet. The brand names you're most likely to see on the store shelf include stalwarts such as Listerine, Crest, Act, Colgate, Oral-B, Scope, and Cepacol; private label (e.g., CVS, Walgreens, Safeway) mouth rinses also abound. Many come in a variety of flavors (e.g., cool mint, berry blast) and niche formulas target specific issues, such as fighting cavities (look for rinses with fluoride), whitening teeth, eliminating dry mouth, and rebuilding enamel. Many oral rinses also contain alcohol, often in staggeringly high amounts; check the ingredients list carefully if this is an issue for you or anyone in the household (e.g., kids, pregnant women, seniors, and recovering alcoholics).

And remember, don't ever swallow mouthwash. Most importantly, continue to brush regularly – mouth rinse is no substitute for that basic component of every good oral hygiene routine.

Mouthwash Reviews

As with so many personal care products, the choice of a mouthwash is a very personal thing. Predictably, mouthwash reviews are divided, with the majority extolling the benefits of our top picks and the minority condemning them for one thing or another -- horrid taste, for example, or limited staying power. One product we researched was dinged more often than not for unsightly and unpleasant side effects.

First developed in 1895, Listerine Antiseptic Original Mouthwash today is dentist-recommended and carries the ADA's Seal of Acceptance for fighting plaque and gingivitis and decimating bad-breath germs. The original formulation of this brand has carved out a name for itself with its signature spunky -- some say appalling -- taste, but mouthwash reviews at sites such as Amazon give it an enthusiastic thumbs-up for effectiveness. Listerine Antiseptic Original takes some getting used to, reviewers concede, but a daily 30-second flush is worth the discomfort. Benefits range from lower dental bills to very fresh breath and a mouth that feels spanking clean. Some mouthwash reviewers, though, cite negatives such as a burning sensation (alcohol content exceeds 25 percent), a lingering aftertaste, and dry mouth. New flavor introductions, such as Cool Mint and FreshBurst, generate more favorable commentary regarding the taste.

If, despite all the affirmations of effectiveness Listerine Original is a no-go, Act Total Care Anti-Cavity and Scope Original Mint mouthwashes pass as comparatively pleasant alternatives, according to online posts. Act Total Care is often recommended by dental professionals who like the dose of fluoride it delivers; one mouthwash review posted by an army hygienist at Drugstore.com says she urges it on all her patients. Users like the alcohol-free formula, which they say eliminates any burning sensation, and note that the gentle taste appeals regardless of age (i.e., it's good for the kids). In terms of effectiveness, reviewers mention a clean and fresh mouth feel, help for receding gums, and a bill of health from the dentist.

Scope Classic Original Mint is a purely cosmetic mouth rinse – it lays no claim to any dental health benefits and merely trumpets its effectiveness in the war on bad breath germs. Users seem to agree, but with caveats. At Viewpoints, for example, mouthwash reviews say it gets the job done but several report that the effect wears off relatively quickly; one woman says she keeps mints in her purse for freshening up while out and about. Still, reviewers approve of the smooth-tasting formula, with some noting this is why they chose the brand.

Consumers with an all-natural bent might try experimenting with homemade recipes, promoted on numerous frugal and natural/organic blogs. Or, there's Tom's of Maine Cleansing Mouthwash, a commercial all-natural, alcohol-free choice. The brand was acquired by Colgate-Palmolive Co. several years ago and, claim some users in mouthwash reviews at sites such as Drugstore.com, the formula seems to have been altered. This has sparked dismay among long-time users who decry what's variously described as the insipid and artificially sweet taste. Others counter that Tom's of Maine Cleansing mouth rinse continues to be gentle and refreshing.

Crest may be a household name but Crest Pro-Health Multi-Protection is not welcome in some homes. Users who are down on the product report in mouthwash reviews at Walmart, for example, that it stains their teeth, leaves an aftertaste that dulls their taste buds, and partially morphs into little blue gobs after energetic swishing. A few mention a slight burning sensation despite the alcohol-free formula, but some consider this a sign that the germ-killing ingredients are working. On the other hand, a measurable sample of reviewers like the minty taste and clean mouth feel, and say the positive effects are long-lasting.

Additional Products We Considered

Tom's of Maine Cleansing Mouthwash Review

(From $0.29 )

Tom's of Maine Cleansing Mouthwash (starting at $0.29/oz., Amazon) claims its fair share of fervent fans, according to reviews. In posts at Drugstore.com they assert the product freshens their mouths, tastes good, and is gently cleansing. They also express appreciation for the absence of alcohol and other harsh ingredients. On the other hand, long-term users who posted Tom's of Maine Cleansing Mouthwash reviews at Amazon a couple of years ago are sorely disappointed with a reformulated version that first appeared after a corporate buyout. In particular they rail against the different ingredients and the different taste; one states that it leaves a sticky residue and unpleasantly sweet feeling on his gums.

Available in peppermint baking soda and spearmint flavors, Tom's of Maine Cleansing Mouthwash contains xylitol and menthol for flavor and other so-called natural ingredients. The company's mouthwash lineup also includes an anti-cavity fluoride rinse for kids and a Wicked Fresh formulation.

Reviews suggest that consumers who never used the original version will be satisfied with this version of Tom's of Maine Cleansing Mouthwash. If the "natural" label is important and the price (slightly out of the cheap range) not a deterrent, it's probably worth a try.
