What Is CB12 Mouthwash and Does It Really Work?

 

Bad breath — or halitosis — affects a significant number of people at some point in their lives, and it can knock your confidence in social and professional situations. CB12 mouthwash is a clinically developed oral rinse designed specifically to neutralise the volatile sulphur compounds (VSCs) that cause bad breath, rather than simply masking them with fragrance. The NHS notes that poor oral hygiene and bacterial activity in the mouth are among the most common causes of bad breath, which is exactly what this product targets. If you're looking after your overall oral health, you'll find a wide range of products in our oral health collection.

The 250ml blue mint-menthol variant offers a refreshing flavour alongside its active function. At just £4.29, it's an accessible daily-use option for anyone who wants reliable, long-lasting breath protection without needing a prescription.

 

How Does CB12 Mouthwash Work to Neutralise Bad Breath?

 

The science behind CB12 is straightforward but effective. Most mouthwashes rely on strong flavours or alcohol to temporarily cover odour. CB12 takes a different approach by chemically neutralising the compounds responsible for the smell in the first place.

  • Zinc acetate binds to volatile sulphur compounds (VSCs) — particularly hydrogen sulphide and methyl mercaptan — converting them into non-odorous substances.
  • Sodium fluoride helps protect tooth enamel from acid erosion, adding a dental health benefit alongside breath control.
  • The mint-menthol flavour provides an immediate sensation of freshness that complements the active neutralisation process.
  • A single 10ml rinse can provide up to 12 hours of protection, making once-daily use sufficient for most people.

This dual-action approach — neutralising VSCs while also supporting enamel health — sets CB12 apart from standard flavoured rinses.

 

Who Should Consider Using CB12 Mouthwash?

 

CB12 mouthwash is suitable for adults and young people aged 12 and over who experience persistent or occasional bad breath. It's particularly useful if you've already addressed the basics — brushing twice daily, flossing, and staying hydrated — but still find that breath odour is a concern. The NHS recommends regular dental check-ups and good oral hygiene as the foundation of breath management, and CB12 can complement that routine effectively.

  • Adults who experience morning breath or persistent halitosis
  • People who wear dentures or orthodontic appliances, where bacterial build-up is more likely
  • Those who smoke or consume foods known to cause odour (such as garlic or onions)
  • Anyone who wants a fluoride-containing rinse to support enamel health alongside breath control

 

How Does CB12 Mouthwash Compare to Other Mouthwashes?

 

Feature CB12 Mouthwash Standard Mint Mouthwash
Mechanism Neutralises VSCs chemically Masks odour with fragrance

Is CB12 Mouthwash Suitable for Daily Long-Term Use?

 

Yes — CB12 mouthwash is formulated for daily use and is safe for ongoing incorporation into your oral hygiene routine. The zinc acetate and sodium fluoride combination is well tolerated at the concentrations used in this product. If you have any existing dental conditions, are undergoing treatment, or are taking medicines that affect saliva production (which can worsen bad breath), it's worth mentioning CB12 to your dentist or pharmacist before starting. You might also want to explore our dental products collection for complementary items such as toothpastes and interdental brushes.

Store the bottle below 25°C, away from direct sunlight, and keep it out of reach of children. Do not use beyond the printed expiry date.

This product is a medicine. Speak to your doctor or pharmacist before using if you have an underlying medical condition or are taking other medicines.

Specifications of CB12 Blue Mint-Menthol Mouthwash 250ml

 

What Is CB12 Blue Mint-Menthol Mouthwash and What Is It Used For?

 

CB12 mouthwash is an oral rinse used to prevent and manage bad breath (halitosis). It contains two active ingredients — zinc acetate and sodium fluoride — which work together to neutralise the odour-causing volatile sulphur compounds produced by bacteria in the mouth, while also helping to protect tooth enamel. It is available over the counter without a prescription and is intended for use as part of a daily oral hygiene routine. The NHS identifies poor oral hygiene and bacterial activity as the leading causes of bad breath, and products like this one are designed to address that at source.

 

What Do You Need to Know Before Using CB12 Mouthwash?

 

Before using CB12 mouthwash, read the following contraindications and warnings carefully:

  • Do not use if you are under 12 years of age.
  • Do not swallow the mouthwash — it is for rinsing only.
  • Avoid use if you have a known allergy or hypersensitivity to any of the ingredients, including zinc acetate or sodium fluoride.
  • If you are pregnant or breastfeeding, speak to your pharmacist or GP before use, as a precaution.
  • People with dry mouth (xerostomia) should be aware that reduced saliva can worsen bad breath; speak to your dentist about managing the underlying cause.
  • Do not use in children under 12 years — fluoride-containing rinses carry a risk of dental fluorosis if swallowed in excess by young children.

No clinically significant drug interactions have been identified at the concentrations used in this product when used as directed. However, if you are taking medicines that affect saliva production — such as certain antidepressants, antihistamines, or antihypertensives — these may worsen halitosis independently. Speak to your pharmacist if you are unsure.

  • No significant interactions with common oral medications at standard use
  • Avoid using immediately after other fluoride-containing rinses to prevent excessive fluoride intake

 

How Should You Use CB12 Mouthwash Correctly?

 

Using CB12 mouthwash correctly is straightforward, but following the steps below will help you get the most from each use. Consistency matters — daily use is more effective than occasional rinsing.

  1. Brush your teeth as normal before using the mouthwash.
  2. Measure exactly 10ml using the measuring cap provided with the bottle.
  3. Rinse the solution around your mouth for 30 to 60 seconds, making sure it reaches all areas including the back of the tongue.
  4. Spit out completely — do not swallow.
  5. Avoid eating, drinking, or rinsing your mouth with water for at least 30 minutes after use to allow the active ingredients to work effectively.
Indication Age Group Dose Frequency
Bad breath prevention Adults and young people aged 12+ 10ml Once daily
Not applicable Under 12 years Not recommended

 

What Are the Possible Side Effects of CB12 Mouthwash?

 

CB12 mouthwash is generally well tolerated when used as directed. As with any oral hygiene product, some people may experience mild effects, particularly when first starting use. If you experience anything that concerns you, stop using the product and speak to your pharmacist or GP.

Common side effects:

  • Temporary alteration in taste perception
  • Mild tingling or sensation in the mouth
  • Temporary tooth staining with prolonged use (less common with CB12 than with chlorhexidine-based rinses)

Less common side effects:

  • Mild oral mucosal irritation
  • Dry mouth sensation immediately after use
  • Allergic reactions (rare) — stop use immediately and seek medical advice if you notice swelling, rash, or difficulty breathing

If you're managing other aspects of your health alongside your oral care routine, you might find it helpful to browse our vitamins and supplements collection, as nutritional deficiencies can sometimes contribute to oral health issues.

 

How Should You Store CB12 Mouthwash?

 

  • Store below 25°C in a cool, dry place away from direct sunlight.
  • Keep the bottle tightly closed when not in use.
  • Keep out of the sight and reach of children at all times.
  • Do not use after the expiry date printed on the bottle or packaging.
  • Do not store in the bathroom if it is frequently humid — a bedroom shelf or cabinet is preferable.
  • Do not freeze.

If you have any concerns about storage or the condition of the product, speak to your pharmacist. You can also explore our ear, nose and throat collection for related products that support upper respiratory and oral health.

Frequently Asked Questions

Where can I buy CB12 mouthwash online in the UK?

You can buy CB12 mouthwash online in the UK directly from Cured Pharmacy for just £4.29 per 250ml bottle. It is available without a prescription as a general sale oral hygiene product. Simply add it to your basket and select your preferred delivery option at checkout — no appointment or consultation needed.

How does CB12 mouthwash work in the mouth?

CB12 mouthwash works by using zinc acetate to chemically neutralise volatile sulphur compounds (VSCs) — the gases produced by oral bacteria that cause bad breath. Unlike standard rinses that simply mask odour with flavour, CB12 targets the source of the problem directly. Sodium fluoride is also included to help strengthen and protect tooth enamel during daily use.

How do I use CB12 mouthwash step by step?

Measure 10ml using the cap, rinse around your mouth for 30 to 60 seconds, then spit out completely — never swallow. Use it once daily, ideally after brushing your teeth in the morning. Avoid eating, drinking, or rinsing with water for at least 30 minutes afterwards to allow the active ingredients to work fully.

What is the best time of day to use CB12 mouthwash?

The best time to use CB12 mouthwash is in the morning after brushing your teeth, as this gives you up to 12 hours of breath protection throughout the day. Using it consistently at the same time each day helps build an effective routine. If you find morning use inconvenient, evening use after brushing is also acceptable, though daytime protection may be reduced.

What are the side effects of CB12 mouthwash?

Most people tolerate CB12 mouthwash well, but some may notice a temporary change in taste or a mild tingling sensation in the mouth after rinsing. These effects are usually short-lived and settle within minutes. If you experience persistent irritation, swelling, or any signs of an allergic reaction, stop use immediately and speak to your pharmacist or GP.

Is CB12 mouthwash suitable for children?

CB12 mouthwash is not recommended for children under 12 years of age due to the risk of swallowing fluoride-containing rinses, which can cause dental fluorosis in young children if ingested regularly. Young people aged 12 and over may use it as directed under adult supervision. Always store the bottle out of reach of young children.

How long does one bottle of CB12 mouthwash last?

A 250ml bottle of CB12 mouthwash provides approximately 25 uses when the recommended 10ml dose is used each time. At once-daily use, that equates to roughly 25 days of protection from a single bottle. Stocking up is easy through our dental products collection at Cured Pharmacy.

Can I use CB12 mouthwash if I am pregnant?

There is no specific evidence that CB12 mouthwash is harmful during pregnancy when used as directed and not swallowed. However, as a precaution, it is always advisable to speak to your GP or midwife before introducing any new oral health product during pregnancy. Your pharmacist can also offer guidance based on your individual circumstances.

What happens if I accidentally swallow CB12 mouthwash?

Swallowing a small amount accidentally is unlikely to cause serious harm in adults, but CB12 mouthwash is not intended to be ingested. If a child swallows a significant quantity, contact NHS 111 or your nearest A&E immediately and take the bottle with you. Always keep the product out of reach of children to prevent accidental ingestion.

How does CB12 mouthwash compare to Corsodyl?

CB12 mouthwash and Corsodyl work in very different ways. Corsodyl contains chlorhexidine gluconate, which is an antiseptic that kills oral bacteria and is often used for gum disease — but it can cause tooth staining with prolonged use. CB12 specifically targets volatile sulphur compounds to neutralise bad breath and is better suited for daily halitosis management rather than treating active gum disease. Speak to your dentist if you are unsure which product is right for you.

Can I use CB12 mouthwash if I have sensitive teeth?

CB12 mouthwash does not contain alcohol, which makes it generally more suitable for people with sensitive teeth or oral tissues compared to alcohol-based rinses. The sodium fluoride content may also offer some benefit to enamel strength. If you have significant dental sensitivity, it is worth discussing your full oral care routine with your dentist.

How long should I continue using CB12 mouthwash?

CB12 mouthwash is designed for ongoing daily use as part of your regular oral hygiene routine — there is no set maximum duration. Many people use it long-term to maintain consistent breath freshness. If bad breath persists despite regular use, it may indicate an underlying dental or medical issue, and you should consult your dentist or GP.

Does CB12 mouthwash contain alcohol?

CB12 mouthwash is formulated without alcohol, which makes it a more comfortable option for people who find alcohol-based rinses drying or irritating. This also makes it a more suitable choice for those who avoid alcohol for personal, religious, or medical reasons. Always check the full ingredient list on the packaging if you have specific sensitivities.

What are the latest findings on zinc-based mouthwashes for bad breath?

Clinical research consistently supports the use of zinc salts — including zinc acetate — as effective agents for reducing volatile sulphur compounds in the oral cavity, which are the primary cause of halitosis. Studies published in peer-reviewed dental journals have found zinc-containing rinses to be significantly more effective than placebo at reducing VSC levels over time. The NHS recommends addressing the root cause of bad breath through good oral hygiene, and zinc-based rinses like CB12 complement that approach well.

Are there other oral health products I should use alongside CB12 mouthwash?

Yes — CB12 mouthwash works best as part of a complete oral hygiene routine that includes brushing twice daily with a fluoride toothpaste, flossing or using interdental brushes, and attending regular dental check-ups. You can explore a full range of complementary products in our oral health collection. Staying well hydrated and reducing foods known to cause odour can also make a meaningful difference.

How Should You Use CB12 Blue Mint-Menthol Mouthwash?

Using CB12 mouthwash correctly ensures you get the full benefit of its active ingredients. It is designed to be used once daily as part of your regular oral hygiene routine — not as a replacement for brushing, but as a complement to it.

Follow these steps each time you use the product:

What Is the Correct Dose of CB12 Mouthwash?

The recommended dose for adults and young people aged 12 and over is 10ml once daily. Do not use more than the recommended amount, as this will not increase the duration of protection and may increase the risk of side effects.

When Is the Best Time to Use CB12 Mouthwash?

The ideal time to use CB12 mouthwash is in the morning after brushing your teeth. This timing maximises the 12-hour protection window, keeping your breath fresh throughout the working day and into the evening. If you prefer to use it at night, that is also acceptable — just ensure you still avoid eating or drinking for 30 minutes after rinsing.

Consistency is key. Using the mouthwash at the same time each day helps establish a reliable routine and ensures you don't miss a dose.

How Long Can You Use CB12 Mouthwash For?

CB12 mouthwash is suitable for long-term daily use and does not have a maximum treatment duration. Many people incorporate it into their permanent oral hygiene routine without any issues. However, if you notice that bad breath persists or worsens despite consistent use, this may indicate an underlying dental or medical condition — such as gum disease, dry mouth, or a gastrointestinal issue — and you should consult your dentist or GP for further assessment.

Do not exceed the recommended dose. If in doubt, speak to your pharmacist.

What Are the Most Common Side Effects of CB12 Mouthwash?

CB12 mouthwash is well tolerated by the majority of people who use it as directed. The most frequently reported effects are mild and temporary, typically resolving within a short time after rinsing.

  • Temporary alteration in taste — food and drink may taste slightly different for a short period after use
  • Mild tingling or warming sensation in the mouth during or immediately after rinsing
  • Temporary sensation of dryness in the mouth

What Are the Less Common Side Effects of CB12 Mouthwash?

Less commonly, some people may experience mild irritation of the oral mucosa (the soft tissues lining the mouth). This is more likely if you have existing mouth ulcers or areas of sensitivity. If irritation is persistent, discontinue use and seek advice from your pharmacist.

  • Mild irritation or soreness of the gums or inner cheeks
  • Slight discolouration of the tongue — usually temporary and resolves with continued use or on stopping
  • Increased sensitivity to taste for a short period after rinsing

What Are the Serious Side Effects of CB12 Mouthwash?

Serious side effects are rare with CB12 mouthwash when used as directed. However, allergic reactions — though uncommon — can occur with any product. Signs of a serious allergic reaction (anaphylaxis) include swelling of the lips, tongue, or throat, difficulty breathing, a widespread rash, or dizziness. If you experience any of these symptoms, stop using the product immediately and call 999 or go to your nearest A&E.

Swallowing large amounts of the mouthwash — particularly in children — could cause nausea, vomiting, or fluoride toxicity. Keep the product out of reach of children at all times and contact NHS 111 immediately if accidental ingestion occurs.

What Should You Do If You Experience Side Effects From CB12 Mouthwash?

If you experience mild side effects such as taste changes or a tingling sensation, these are generally not a cause for concern and will resolve on their own. You may wish to try rinsing for a shorter duration (30 seconds rather than 60) to see if this reduces the sensation. If side effects are persistent, bothersome, or worsen over time, stop using the product and speak to your pharmacist or GP. You can also report suspected side effects to the MHRA via the Yellow Card scheme at yellowcard.mhra.gov.uk.

Can CB12 Mouthwash Interact With Other Medicines?

No clinically significant drug interactions have been identified with CB12 mouthwash at the concentrations used when the product is applied as directed and not swallowed. However, if you are taking medicines that reduce saliva production — such as certain antidepressants, antihistamines, or blood pressure medications — these may independently worsen bad breath by causing dry mouth. Using CB12 alongside these medicines is generally safe, but speak to your pharmacist if you have any concerns about your specific medication regimen.

If you are concerned about any side effects, contact your pharmacist or GP immediately.
