WHAT IT IS / WHAT IT DOES

Kank-A® Mouth Pain Liquid is a topical oral anesthetic formulated to temporarily relieve pain associated with minor sores and irritation inside the mouth.

It combines benzocaine with film-forming ingredients that create a protective coating over the affected area.

1. Maximum-Strength Benzocaine

Benzocaine is a local anesthetic that temporarily reduces pain sensation by blocking nerve signals near the application site.

Kank-A® contains 20% benzocaine, a maximum-strength concentration commonly used in certain over-the-counter oral anesthetic products.

The medication provides temporary symptom relief but does not treat the underlying cause of mouth sores.

2. Protective Film Barrier

The liquid contains ingredients that form a coating over the affected area.

This protective layer helps reduce direct contact between the sore and potential irritants, including:

• Food
• Beverages
• Dentures
• Orthodontic appliances
• Adjacent oral tissues

The coating may help maintain contact between the anesthetic and the affected area.

3. Targeted Canker Sore Relief

Canker sores, also called aphthous ulcers, are small, painful lesions that develop inside the mouth.

Kank-A® temporarily relieves pain associated with these sores.

It does not cure canker sores or necessarily shorten their healing time.

4. Relief from Minor Oral Irritation

Kank-A® can also provide temporary relief from minor irritation caused by dentures, braces and accidental mouth injuries.

Persistent irritation from dental appliances should be assessed by a dentist.

How Does Benzocaine Work?

Benzocaine temporarily blocks nerve signals responsible for transmitting pain sensations.

When applied to a localized mouth sore, it helps reduce discomfort at the application site.

Important: Benzocaine can cause methemoglobinemia, a serious condition that reduces the blood’s ability to carry oxygen. This risk can occur even when the product has been used previously without problems.

3. Allow a few seconds for the protective coating to form.
4. Use up to 4 times daily, or as directed by a dentist or physician.

Children Aged 2–11 Years

Use only with adult supervision and after consulting a healthcare professional.

Benzocaine-containing oral products carry significant safety concerns in young children.

Children Under 2 Years

DO NOT USE.

HOW TO APPLY

For best results:

• Apply only to the affected area.
• Avoid unnecessary application to surrounding healthy tissue.
• Allow the coating to form before eating or drinking.

PAIR WITH

Complement Kank-A® Mouth Pain Liquid with oral care essentials that support gentle hygiene and help minimize additional irritation.

1. Soft-Bristle Toothbrush

Gentle Oral Hygiene

A soft-bristle toothbrush helps clean teeth while reducing unnecessary friction against sensitive gums and oral tissues.

Why pair them? Gentle brushing can help maintain oral hygiene while a minor mouth sore heals.

2. Alcohol-Free Mouthwash

Gentle Daily Oral Care

An alcohol-free mouthwash may be more comfortable than alcohol-containing rinses for individuals with sensitive oral tissues.

Why pair them? Supports daily oral hygiene without introducing additional alcohol-related irritation.

Choose a rinse appropriate for mouth sores, as some antiseptic or strongly flavoured products may still sting.

3. Sensitive Toothpaste

Everyday Oral Hygiene

A mild toothpaste can help maintain oral hygiene while minimizing irritation.

Why pair them? Some individuals with recurrent canker sores prefer toothpaste formulated without sodium lauryl sulphate (SLS).

4. Oral Hygiene Essentials

Complete Daily Dental Care

Pair Kank-A® with suitable toothbrushes, toothpaste and gentle oral care products.

Why pair them? Maintaining good oral hygiene is important while managing minor mouth irritation.

CHP Shopping Tip: Avoid recommending another benzocaine-containing oral anesthetic alongside Kank-A®. Combining similar products can increase medication exposure without necessarily improving relief.
