Is Aloclair Plus the Right Mouth Ulcer Gel for You?

 

Mouth ulcers are one of those things that seem small until you actually have one. Eating, drinking, even talking can become genuinely uncomfortable. Mouth ulcer gel is one of the most searched-for remedies in the UK for good reason — a well-formulated topical gel can make a real difference to how quickly you recover and how much pain you experience in the meantime. Aloclair Plus Gel 8ml is a clinically designed, alcohol-free gel that creates a physical barrier over the ulcer, helping to reduce pain and support natural healing. You can explore the full range of dental products available at Cured Pharmacy if you're looking for broader oral care support.

Mouth ulcers — also known as aphthous ulcers — are small, shallow sores that develop on the soft tissues inside the mouth. According to the NHS, they are very common and usually clear up on their own within one to two weeks, though treatment can ease discomfort significantly. Aloclair Plus Gel is available over the counter without a prescription, making it a convenient first-line option for most adults.

 

How Does Aloclair Plus Gel Work on Mouth Ulcers?

 

The mechanism behind Aloclair Plus Gel is straightforward but effective. Rather than relying on a local anaesthetic or antiseptic alone, it uses a film-forming approach to physically protect the ulcer from further irritation.

  • Film formation: Polyvinylpyrrolidone (PVP) and hypromellose work together to create a thin, adherent film over the ulcer surface once the gel is applied.
  • Moisture retention: Sodium hyaluronate helps maintain a moist wound environment, which is associated with faster tissue repair.
  • Soothing action: Aloe vera extract provides a calming effect on inflamed mucosal tissue.
  • Barrier protection: The film shields the raw ulcer from contact with food, drink, saliva, and bacteria, reducing the pain signals triggered by these irritants.

Because the gel is alcohol-free and does not contain local anaesthetics, it is generally well tolerated and does not carry the risk of masking pain in a way that might delay seeking further advice if needed.

 

Who Should Use Aloclair Plus Gel for Mouth Ulcer Relief?

 

This gel is suitable for a wide range of people dealing with common oral ulcers. It is particularly useful if you find that eating and drinking are painful, or if you have an ulcer in an awkward spot — near the gum line or on the inner cheek, for example — where a gel can adhere more easily than a rinse or spray.

  • Adults and teenagers aged 12 and over with minor aphthous ulcers
  • People who have developed ulcers following dental treatment or minor oral trauma
  • Those who prefer an alcohol-free, non-anaesthetic topical option
  • Individuals who wear dentures or braces and experience friction-related ulcers

It is not intended for use in children under 12 without medical advice. If you are unsure whether this product is right for you, speak to your pharmacist before use.

 

How Does Aloclair Plus Gel Compare to Other Mouth Ulcer Treatments?

Is Aloclair Plus Gel Suitable to Store at Home?

 

Yes. The 8ml tube is compact and easy to keep in a bathroom cabinet or handbag. Store it below 25°C, away from direct sunlight, and keep it out of reach of children. Do not use the gel after the expiry date printed on the packaging. Once opened, use within the period indicated on the tube.

If you are managing other minor health concerns alongside mouth ulcers, you might also find our oral health collection helpful for a broader range of products. As a mouth ulcer gel, Aloclair Plus is designed for short-term topical use only — it is not a treatment for underlying systemic conditions that may be causing recurrent ulcers.

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.

What Is Aloclair Plus Gel and What Is It Used For?

 

Aloclair Plus Gel is a topical oral gel used to relieve the pain and discomfort associated with mouth ulcers, also known as aphthous ulcers. It is classified as a medical device rather than a medicinal product in the traditional sense, meaning it works through physical action — forming a protective film — rather than pharmacological activity. The NHS notes that mouth ulcers are very common and usually harmless, but they can be painful and interfere with eating, drinking, and speaking. Aloclair Plus Gel is designed to reduce that discomfort while the ulcer heals naturally.

The gel is suitable for minor ulcers caused by biting the inside of the cheek, dental appliances, or spontaneous aphthous episodes. It is not intended to treat ulcers caused by infections, systemic disease, or malignancy. If you have an ulcer that has not healed within two weeks, you should seek advice from your GP or dentist.

 

What Do You Need to Know Before Using Aloclair Plus Gel?

 

Before using this gel, please read the following carefully. Although Aloclair Plus Gel is generally well tolerated, there are some situations where caution is needed.

Do not use Aloclair Plus Gel if:

  • You are allergic to any of the ingredients, including Aloe vera or sodium hyaluronate
  • The ulcer is unusually large, deep, or has not healed after two weeks
  • You are using it on a child under 12 years of age without first consulting a pharmacist or GP
  • The ulcer is accompanied by fever, difficulty swallowing, or other systemic symptoms

Warnings and precautions:

  • Avoid contact with eyes
  • Do not swallow large amounts of the gel
  • If you are pregnant or breastfeeding, consult your pharmacist before use
  • Recurrent or unusually painful ulcers may indicate an underlying condition — speak to your GP

Known drug interactions:

  • No clinically significant drug interactions have been identified for Aloclair Plus Gel
  • As a topical product with minimal systemic absorption, interactions with oral medicines are considered unlikely

 

How Should You Use Aloclair Plus Gel Correctly?

 

Using the gel correctly makes a real difference to how well it works. The key is allowing the film to form properly before eating or drinking. Follow these steps each time you apply it.

  1. Dry the ulcer area gently with a clean tissue or cotton bud if possible
  2. Squeeze a small amount of gel (approximately 0.5cm) onto a clean fingertip or cotton bud
  3. Apply directly to the ulcer, covering it completely
  4. Hold in place for approximately 30 seconds without touching the area
  5. Avoid eating, drinking, or rinsing your mouth for at least 30 minutes after application
  6. Repeat up to three times daily, or as directed by your pharmacist
Indication Age Group Dose Frequency
Minor aphthous ulcer Adults (18+) Small amount (~0.5cm) Up to 3 times daily
Minor aphthous ulcer Adolescents (12–17) Small amount (~0.5cm) Up to 3 times daily
Traumatic/friction ulcer Adults (18+) Small amount (~0.5cm) Up to 3 times daily

If you are also managing other types of oral discomfort, our pain relief collection includes a range of products that may complement your care.

 

What Are the Possible Side Effects of Aloclair Plus Gel?

 

Aloclair Plus Gel is generally very well tolerated. Because it does not contain alcohol or local anaesthetics, the risk of irritation is lower than with some other mouth ulcer products. That said, as with any topical product, reactions can occasionally occur.

Common side effects:

  • Mild, transient stinging or tingling immediately after application
  • Temporary altered taste sensation

Less common side effects:

  • Localised redness or irritation at the application site
  • Hypersensitivity reaction (rare) — stop use immediately if this occurs

If you experience any unexpected or persistent reaction, discontinue use and speak to your pharmacist or GP. Signs of a serious allergic reaction — such as swelling of the lips, tongue, or throat, or difficulty breathing — require immediate medical attention.

 

How Should You Store Aloclair Plus Gel?

 

Correct storage helps maintain the integrity of the gel and ensures it remains effective for the duration of use.

  • Store below 25°C in a cool, dry place
  • Keep away from direct sunlight and heat sources
  • Keep the cap tightly closed when not in use
  • Keep out of reach and sight of children
  • Do not use after the expiry date printed on the tube or carton
  • Do not freeze

If you are looking for other products to support your general health alongside this treatment, our vitamins and supplements collection includes options that may support immune function and overall wellbeing. Some research suggests that deficiencies in vitamin B12, iron, or folate may be associated with recurrent aphthous ulcers, so it is worth discussing this with your GP if ulcers are a frequent problem for you.

Frequently Asked Questions

Where can I buy Aloclair Plus Gel online in the UK?

You can buy Aloclair Plus Gel 8ml directly from Cured Pharmacy, a GPhC-registered UK online pharmacy, for just £4.50. It is available without a prescription as an over-the-counter product. Simply add it to your basket and it will be dispatched promptly to your door.

How does Aloclair Plus Gel work on mouth ulcers?

Aloclair Plus Gel works by forming a thin, adherent protective film over the surface of the ulcer when applied. This film physically shields the raw tissue from contact with food, drink, saliva, and bacteria — all of which can trigger pain signals. By reducing that irritation, the gel allows the underlying mucosa to heal more comfortably.

How do I use Aloclair Plus Gel step by step?

Dry the ulcer area gently, then apply a small amount of gel directly onto the ulcer using a clean fingertip or cotton bud. Hold it in place for around 30 seconds to allow the film to set, then avoid eating or drinking for at least 30 minutes. You can repeat this up to three times a day.

How quickly does Aloclair Plus Gel relieve pain?

Many people notice a reduction in discomfort within minutes of applying the gel, as the protective film immediately reduces contact between the ulcer and oral irritants. The gel does not contain a local anaesthetic, so the relief comes from physical protection rather than numbing. Full healing of the ulcer typically takes between seven and ten days.

Is Aloclair Plus Gel suitable for children?

Aloclair Plus Gel is considered suitable for adults and young people aged 12 and over. For children under 12, you should consult a pharmacist or GP before use, as the product has not been specifically studied in younger children. If your child has a mouth ulcer, the NHS recommends seeking professional advice if it does not clear within two weeks.

What are the side effects of Aloclair Plus Gel?

Side effects are uncommon but may include mild, transient stinging or tingling immediately after application, and occasionally a temporary change in taste. Localised irritation or redness at the application site is less common. If you experience any persistent or worsening reaction, stop using the gel and speak to your pharmacist.

Can I use Aloclair Plus Gel during pregnancy or breastfeeding?

Aloclair Plus Gel is applied topically to the oral mucosa and is not significantly absorbed into the bloodstream, which means systemic exposure is minimal. However, as a precaution, if you are pregnant or breastfeeding you should speak to your pharmacist or GP before using any new product. They can help you weigh up the benefits and any potential concerns.

How long can I use Aloclair Plus Gel for?

You can use Aloclair Plus Gel for as long as the ulcer persists, which is usually no more than seven to ten days for a typical minor aphthous ulcer. If your ulcer has not healed after two weeks of treatment, or if you are getting ulcers very frequently, you should see your GP or dentist to rule out an underlying cause. Prolonged or recurrent ulcers can sometimes be linked to nutritional deficiencies or other health conditions.

What are the alternatives to Aloclair Plus Gel for mouth ulcers?

Common alternatives include Bonjela (which contains choline salicylate and is not recommended for under-16s), corticosteroid-based pellets such as hydrocortisone buccal tablets, and chlorhexidine mouthwash to reduce secondary bacterial involvement. You can browse our oral health collection for a wider range of options. The right choice depends on the size, location, and frequency of your ulcers.

Does Aloclair Plus Gel contain alcohol or anaesthetics?

No — Aloclair Plus Gel is alcohol-free and does not contain local anaesthetics such as lidocaine or benzocaine. This makes it a gentler option for people who find alcohol-based gels irritating, or who prefer to avoid anaesthetic ingredients. The soothing effect comes from the physical film and the Aloe vera extract rather than any numbing agent.

Can I eat and drink after applying Aloclair Plus Gel?

It is recommended that you avoid eating or drinking for at least 30 minutes after applying the gel, to give the protective film time to adhere properly to the ulcer surface. Eating or drinking too soon after application may wash the gel away before it has had a chance to work. Timing your application between meals is a practical way to get the most benefit.

What causes mouth ulcers to keep coming back?

Recurrent aphthous ulcers can be triggered by a range of factors including stress, hormonal changes, minor oral trauma, certain foods, and nutritional deficiencies — particularly in vitamin B12, iron, or folate, as noted by the NHS. Some people have a genetic predisposition to them. If you are getting ulcers frequently, it is worth speaking to your GP, as they may want to check your blood levels or investigate other possible causes.

Is Aloclair Plus Gel the same as Aloclair Plus Mouthwash?

No — they are different formulations from the same brand. The gel is applied directly to the ulcer for targeted, localised protection, while the mouthwash is used as a rinse and may be more suitable for multiple ulcers or hard-to-reach areas. The gel tends to be preferred when you need precise application to a single ulcer. Both are available over the counter in the UK.

What is the latest research on mouth ulcer gel treatments?

Research into aphthous ulcer management continues to focus on barrier-forming agents, anti-inflammatory treatments, and the role of the oral microbiome. Film-forming gels containing hyaluronic acid and PVP have shown positive results in clinical studies for reducing pain and healing time compared to placebo. If you are interested in broader pain management options, our pain relief collection includes a variety of evidence-based products.

Does Aloclair Plus Gel interact with any medicines?

No clinically significant drug interactions have been identified for Aloclair Plus Gel. Because it is applied topically to the oral mucosa and is not meaningfully absorbed into the bloodstream, interactions with systemic medicines are considered very unlikely. If you are taking multiple medicines and have any concerns, your pharmacist is always the best person to ask.

How Should You Use Aloclair Plus Gel?

Aloclair Plus Gel is designed for direct topical application to the ulcer. Getting the technique right means the protective film can form properly and stay in place long enough to make a real difference. Before you apply the gel, try to dry the ulcer area gently with a clean tissue — this helps the gel adhere more effectively to the mucosal surface.

What Is the Correct Dose of Aloclair Plus Gel?

The dose is the same for all eligible users — a small, pea-sized amount applied directly to the ulcer. You do not need to use more than this; applying a larger quantity does not improve the protective effect and may simply be wasteful. Always follow the instructions in the product leaflet and do not exceed three applications per day.

When Is the Best Time to Use Aloclair Plus Gel?

Timing your applications around meals is the most practical approach. Apply the gel after eating and after brushing your teeth, so the film has the maximum amount of time to remain undisturbed before your next meal or drink. A good routine is to apply it after breakfast, after lunch, and again before bed — this spaces the three daily applications evenly and ensures overnight protection when saliva flow is reduced and the film can work most effectively.

How Long Can You Use Aloclair Plus Gel For?

Continue using the gel until the ulcer has fully healed. Most minor mouth ulcers resolve within seven to ten days with or without treatment, but using the gel consistently throughout this period can significantly reduce discomfort. If your ulcer has not healed after two weeks of regular use, or if new ulcers keep appearing, stop using the product and consult your GP or dentist — recurrent or persistent ulcers can sometimes indicate an underlying health issue that needs investigation.

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

What Are the Most Common Side Effects of Aloclair Plus Gel?

Aloclair Plus Gel is generally very well tolerated, and most people use it without experiencing any unwanted effects. Because it is alcohol-free and does not contain local anaesthetics, it tends to cause less irritation than some other mouth ulcer products. That said, a small number of users may notice mild effects immediately after application.

  • Mild, transient stinging or tingling at the application site
  • Temporary altered or unusual taste sensation
  • Slight sensation of dryness in the mouth as the film sets

What Are the Less Common Side Effects of Aloclair Plus Gel?

Less commonly, some people may experience a localised reaction at the site of application. These effects are not typical and usually resolve quickly once the product is discontinued. If you notice any of the following, stop using the gel and speak to your pharmacist.

  • Localised redness or increased irritation around the ulcer
  • Worsening of pain rather than improvement after several applications
  • Swelling of the surrounding soft tissue

What Are the Serious Side Effects of Aloclair Plus Gel?

Serious side effects are rare with Aloclair Plus Gel. However, hypersensitivity reactions — including allergic responses to Aloe vera or sodium hyaluronate — can occasionally occur in susceptible individuals. Signs of a serious allergic reaction include swelling of the lips, tongue, or throat, difficulty breathing, a widespread skin rash, or dizziness. If you experience any of these symptoms, stop using the product immediately and seek emergency medical attention by calling 999 or going to your nearest A&E department.

What Should You Do If You Experience Side Effects of Aloclair Plus Gel?

For mild side effects such as transient stinging, no specific action is usually needed — the sensation typically passes within a minute or two. If you experience persistent irritation or a worsening reaction, discontinue use and consult your pharmacist. They can advise whether an alternative mouth ulcer treatment might be more suitable for you. Keep a note of any symptoms you experience so you can describe them accurately when seeking advice.

Can Aloclair Plus Gel Interact With Other Medicines?

No clinically significant interactions between Aloclair Plus Gel and other medicines have been identified. The gel is applied topically to the oral mucosa and is not meaningfully absorbed into the systemic circulation, which means it is very unlikely to affect the way other medicines work in your body. If you are taking multiple medicines — particularly immunosuppressants or medicines that affect wound healing — it is always sensible to mention any new products to your pharmacist or GP as a precaution.

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