10 Best Mouthwashes for Gums in the UK 2023

We all know that brushing our teeth twice a day is essential for oral hygiene, but if you want to ensure that your gums are healthy too, then adding a mouthwash to your routine can really make a difference. This type of product contains ingredients that can help to prevent the development of health problems such as gum disease, bleeding gums, and receding gums, as well as heal swelling, inflammation, and bad breath. 


However, not all mouthwashes are made equal - depending on your needs, you may require something alcohol-free for a dry mouth, a formula specifically for sore/sensitive gums, or a natural product without chemicals like fluoride. To help you out, we've created a buying guide covering what to look out for when shopping for a mouthwash. Plus, we've curated a list of the best ones to buy at Amazon and eBay, from brands like Listerine, Colgate, and Corsodyl.

What Is a Mouthwash?

What Is a Mouthwash?

Mouthwash usually comes in the form of a liquid, which you gargle or swish around your mouth for 30 seconds to one minute after brushing your teeth with toothpaste. It has three main benefits: freshens your breath, loosens debris between teeth, and prevents the build-up of plaque (one of the main causes of tooth decay).


Mouthwash is beneficial for gum health because it can clean areas that your toothbrush may not be able to reach. You can also choose a formula that corresponds to your oral hygiene needs - for example, there are rehydrating mouthwashes for dry gums or ones with strengthening ingredients if you have weak teeth.

How to Choose a Mouthwash for Gums in the UK – Buying Guide

So, let's run through what you should look out for when deciding on a mouthwash to buy. Factors that we'll cover include the pros and cons of common ingredients, how to pick a child-friendly product, and which flavour to choose.

1

Understanding the Ingredients List Is Key to Finding the Right Mouthwash for Your Gums

In this section we'll look at ingredients that are commonly found in mouthwash, such as fluoride, ethanol, cetylpyridinium chloride, chlorhexidine, and essential oils. This will help you to make an informed decision about which product will work best with your gums.

Fluoride Can Strengthen Sensitive Teeth, But Some Consumers May Prefer to Avoid It

Fluoride Can Strengthen Sensitive Teeth, But Some Consumers May Prefer to Avoid It

Fluoride is a common ingredient in both toothpaste and mouthwash products, as it can help to strengthen sensitive teeth. By slowing the breakdown of enamel (the outer layer of a tooth), it can prevent the build-up of bacteria that cause cavities and tooth decay.


However, some people prefer to avoid fluoride due to the fact that it's a chemical and there are some health concerns over ingesting it. Whilst it's recommended that we spit mouthwash out after using it, small amounts may still be accidentally ingested. 


Over time, the ingested fluoride may cause "fluorosis", where the teeth permanently turn brown or mottled as a result of a lack of enamel mineralisation. Although this isn't a guaranteed consequence of using a fluoride product, you still might prefer to choose something with more natural ingredients.

Dry or Sore Gums? Opt for an Alcohol-Free Formula

Dry or Sore Gums? Opt for an Alcohol-Free Formula

Another ingredient that's typically found in mouthwash is ethanol, a type of alcohol used as both a preservative and a carrier for the formula's other active ingredients. However, those who often experience a dry mouth (known as xerostomia) or have sore gums should avoid this ingredient, as it can cause irritation and further discomfort


Instead, try an alcohol-free mouthwash that will still leave you with fresh breath but won't dry your gums out. There are even formulas that are designed especially for people with dry mouths - these contain enzymes which can mimic the sensation of saliva and make your mouth feel moisturised! 


For children, those who abstain from alcohol for personal reasons, and people with religious beliefs that prohibit alcoholic products, we also suggest this type of mouthwash as an alternative.

Anti-Bacterial Ingredients Help to Fight Plaque and Prevent Bad Breath

Anti-Bacterial Ingredients Help to Fight Plaque and Prevent Bad Breath

Even with regular brushing, substances like plaque (a sticky bacterial film) can form on your teeth after meals - this can turn into tartar, which causes discolouration, if left to harden. Anti-bacterial ingredients like cetylpyridinium chloride and chlorhexidine can help to reduce plaque and control the onset of receding or bleeding gums, as well as preventing bad breath.


Essential oils such as menthol, eucalyptus, and thyme also have antibacterial and antifungal properties, which can penetrate the plaque biofilm and inhibit bacterial growth. Plus, they leave your mouth feeling nice and fresh!

Make Sure You Choose a Suitable, Gentle Product If Buying for Children

Make Sure You Choose a Suitable, Gentle Product If Buying for Children

As we've just mentioned, alcohol-based mouthwash is a no-no for little ones, as it can be very harmful if ingested. Similarly, fluoride-based products can cause fluorosis if a child's teeth are not yet fully developed. 


Luckily, there are mouthwashes out there that are designed specifically for children, with a gentle formula that won't damage their baby teeth. Choosing one of these products ensures that your kids will be safe when swishing. You should also make sure to always supervise your little ones, in case they accidentally swallow some of the product.

Decide on the Right Flavour To Leave Your Mouth Feeling Refreshed

Decide on the Right Flavour To Leave Your Mouth Feeling Refreshed
Mint is probably the most popular and traditional flavour when it comes to mouthwash - it has a cooling effect and leaves your mouth feeling invigorated. But if you're looking to try something different, there are plenty of other flavours on the market!

Citrus is another top option which tastes fresh and clean, whereas clove (a common ingredient in natural formulas) has an unusual yet refreshing spicy flavour. Lastly, fruity mouthwashes tend to be especially popular with younger children.

This dual-action mouthwash by Dentyl combines a water-based solution to remove bacteria and plaque with a mix of essential oils designed to freshen breath. Shake the bottle vigorously to activate these two formulas together, and prepare for visible results!


We love the bright colour and strong clove flavour of this product, although it might be too spicy for sensitive mouths. Nevertheless, according to a study, it did find that using this mouth twice-daily reduced plaque by more than 60% after one month of use.

This convenient powder by Swish To Go makes oral hygiene quick and fun! You don't even need water - just tear open the sachet, swish it around for 10 seconds, and swallow when you're done. 


As well as tasting great, this product neutralises the pH levels to prevent bacteria growth in your mouth. The fact that it's safe to swallow also means you won't have to worry about it affecting your little one's health either. It's a shame that it's not the most cost-effective option, but it could be handy for holidays as it won't leak in your bag or suitcase.

Combines Organic Ingredients With a Spicy Flavour

This all-natural formula by Nature's Answer is totally free from both fluoride and alcohol. It contains a unique combination of organic botanical ingredients to cleanse the mouth, as well as vitamins like folic acid that support gum health.

Sadly, the clove and cinnamon flavour may not be to everyone's taste, and the high price of this product is likely to put some potential buyers off. However, if you prefer to use an all-natural product that doesn't use any chemicals or artificial preservatives or sweeteners, then this is very much worth its price tag.
