Best Mouthwashes

Taking dental hygiene into great account should never be ignored and underestimated, as healthy teeth is an important phase of the grooming process. Daily, food, coffee, and anything you consume can stain your teeth and cause many harmful bacteria, leading to bad breath and unwanted gum disease.

That’s where best mouthwashes come around, bringing about undebatable benefits like ensuring excellent oral health, eliminating bad breath while protecting our teeth against gum disease and decay. However, the wide variety of mouthwash products on the market sometimes makes it challenging for users to choose a suitable mouthwash brand. If you are struggling with this problem, let’s follow the top 10 best sellers below to find an excellent product for you.

How To Distinguish Among Mouthwashes, Mouth Rinse, And Salt Water Rinse ?

If you are not an expert on dental hygiene, it is an uphill struggle to differentiate mouthwashes, mouth rinses, and saltwater rinses, and we bet that you may use those terms wrongly sometimes. Here are some brief differences that you should not ignore:


Mouthwashes are normally used after brushing and flushed your teeth to get rid of any remaining germ or bacteria that cannot be eliminated by normal toothpastes. There are various formulas of mouthwashes, each based on the primary purposes like antiseptic mouthwash and gum disease mouthwash, thus containing specific ingredients and components. Therefore, you must consider carefully what you will use the product for.


Mouth Rinse

Contrary to mouthwash, rinse mouthwash is effective and useful in your dental condition before you brush and floss your teeth. Specifically, it is used to add more moisture to your gums to offer a fresh breath. Besides, as mouth rinse tends to provide your teeth with moisture, this type of mouth care is sure never to contain alcohol, the ingredient used to provide you with a dry mouth. For this reason, if you want to keep your mouth clean and dry, let’s pick a mouth rinse as a part of your oral care routine.

Salt Water Rinse

Saltwater rinse has some similar characteristics and ingredients with mouthwash. However, this product comes at a much more reasonable and affordable price than mouthwashes, as you can make a bottle of saltwater rinse on your own at home with a combination of freshwater and salt.

Therefore, if you are on a tight budget or allergic to any chemical components in a mouthwash, saltwater rinse is your ideal choice, a natural remedy for your bad breath. Nevertheless, as saltwater is not always tasty and easy to swallow, it may be off-putting to some people.

Types Of Mouthwashes

While most products on the market look the same and show similar results, you need to distinguish a wide range of mouthwash types to choose the most suitable one. In general, there are seven main mouthwash types, each with distinct functions and purposes.

The most common commercial mouthwash is antiseptic, comprising chlorhexidine gluconate. This ingredient is helpful for those with mouth infections and bad breath, as it can curb bacterial growth and reduce plague. Another mouthwash is the cosmetic type, used to hide bad breath but not powerful enough to protect your teeth against decay and other problems.

On the other hand, fluoride mouthwashes include sodium fluoride, thus improving your teeth’ health and preventing tooth decay. In contrast, therapeutic mouthwashes are recommended and prescribed by doctors and dentists to treat ulcers and similar problems. If you are not looking for alcoholic and fluoride effects, natural products are your salvage. They work as effectively as other mouthwashes and deal with mouth injuries and infections.

When it comes to total care mouthwashes, they feature antibacterial properties to curb the plague build-up and protect your teeth from any possible gum disease. The most powerful products are antimicrobial mouthwashes, as they are manufactured to kill dangerous bacteria like gingivitis. So if you have serious dental problems, don’t hesitate to purchase one.

How To Buy The Best Mouthwashes In The UK ?

Without a shade of doubt, most mouthwashes aim at the same targets: reducing the chance of oral diseases, preventing bacteria and germs from reproducing, while offering users a fresh breath. However, not all mouthwashes are suitable and perfectly work with your teeth’s health; therefore, let’s flick through the following factors to choose your ideal mouthwashes wisely:

Type of mouthwash

If you have done some research on mouthwashes on the internet, you are sure to come across two main types of mouthwash: cosmetic and therapeutic. They are the best-selling products with their unique functions and uses. Cosmetic mouthwashes are specially designed for those desiring to get rid of chronic bad breath and maintain natural breath freshness thanks to the combination of essential ingredients like alcohol, flavours, and preservatives.

Besides, cosmetic mouthwash is also used to whiten your teeth with bleaching agents like hydrogen peroxide and detergents. Those ingredients are powerful enough to remove stains and offer you perfect teeth. However, cosmetic mouthwash primarily focuses on providing users with an attractive and appealing look but not effective in dealing with oral problems like gum diseases or decay.

On the other hand, therapeutic mouthwash targets gingivitis and gum inflammation due to plaque buildup. Unwanted plaque can gradually cause aches and sores in your teeth; thus, you need to use this type of mouthwash to reduce pain and remove this annoying plaque. Moreover, the fluoride included in this mouthwash also protects your teeth from decay and cavities.

In general, if you are looking for an effective method for oral health problems, let’s choose between those two. Nevertheless, for those avoiding chemicals and longing for a natural solution, a saltwater rinse would be a better choice.

Bottle size

When purchasing a mouthwash, you probably find your ideal product coming in various sizes, from small, travel-sized to large bottles. A large bottle is suitable for a large family, while a smaller one works perfectly for a single or couple. Overall, while a larger bottle seems to cost less and reasonably, we highly recommend you to buy smaller and travel-sized bottles for the following reasons.

Best Mouthwashes

A small bottle is perfect for a holiday, a picnic, or a business trip, compact enough to bring around yet adequate for you to use regularly. Besides, buying a small bottle means you can have a wide range of flavours and see which one suits you best. This buying practice also keeps your fresh mouthwash so that you are less likely to grow out of using just one flavour.

Active ingredients and chemicals

As mentioned above, the ingredients in mouthwash vary based on different formulas and brands; however, there are still some common ingredients, including alcohol, essential oils, fluoride, triclosan, and some other chloride chemicals like cetylpyridinium chloride.

Alcohol is one of the essential ingredients in mouthwash, which actively kills bacteria, keeps a clean mouth. However, too much alcohol in mouthwash can adversely lead to more powerful saliva production and, consequently, a breeding ground for bacteria. Therefore, don’t forget to check the amount of alcohol first.

Essential oils are widely used in natural mouthwashes, as they provide some additional benefits, according to some dentists. Nevertheless, it would be best to use mouthwash with essential oils too frequently, like daily; let’s use it on occasion only.

Besides, fluoride, a common ingredient in toothpaste, is overwhelmingly effective in fighting cavities while protecting and strengthening your teeth. Other sodium chloride chemicals are also useful in mouthwashes to fight against oral diseases; however, if you are sensitive to dental care, check those quantities first to ensure that the products are suitable for your teeth health.

ADA seal of acceptance

The American Dental Association tends to provide a seal of acceptance for safe to use mouthwash, adding a level of trust and reliability to purchasers. This quality assurance measure is commonly applied and found on well-known brands like Crest, Colgate, and Listerine. Therefore, when purchasing a mouthwash, remember to check this assurance for the best product.

Frequently Asked Questions

How often should I use mouthwashes?

This is one of the most commonly asked questions about mouthwashes, as some users show their doubt and worry about the safety of those products. We are here to assure you that while mouthwashes comprise some additional chemicals, those ingredients are 100% healthy and do no harm to your teeth and overall health condition. That means no matter how frequently you use mouthwashes; they are useful and good for your teeth all the time.

In general, if your teeth are in good condition, you should use a mouthwash twice a day to reduce the remaining plaque and gingivitis. On the other hand, for those with more severe tooth problems like decay, it would be better to use more mouthwashes. Moreover, don’t forget to swish the mouthwash for about 30 seconds before spitting it out for the best effects.

Why do mouthwashes burn so badly in my mouth?

One of the drawbacks of using mouthwash is the burning sensation when you swish it around your mouth. Two main reasons are explaining this burning feeling. The first one is that a badly burning sensation directly comes from the removal of germs and bacteria. When the chemicals eliminate harmful bacteria, they can make your mouth tissues irritated.

Besides, this burn is also a result of the alcohol included as an ingredient in some mouthwashes. Despite this burning sensation, this ingredient helps users curb the bacteria’s reproduction and keeps their mouths clean and dry all the time. However, if you don’t like this alcoholic effect, there are plenty of alcohol-free mouthwashes on the market for you to choose from.

Can mouthwashes replace regular brushing?

While mouthwash is one of the greatest methods for better dental hygiene, preventing various oral diseases like cavities, periodontal disease, and gingivitis, brushing seems to overshadow mouthwashes in cleaning your teeth physically.

By brushing your teeth twice a day, you are more likely to remove unwanted plaque and visible germs, effectively whitening your teeth. Thanks to this, you feel more confident and leave a stunning impression on your partners and surrounding people.

Furthermore, brushing, together with flossing, is the best way to remove any remaining food trapped between teeth, which mouthwash is not as effective in removing as this method.
