Who It’s Ideal For

Kank-A® products may be suitable for people experiencing:

• Canker sores

• Minor mouth or gum irritation

• Accidental cheek or lip bites

• Irritation associated with braces

• Denture-related rubbing or sore spots

• Minor oral discomfort from hot foods

• Tooth or gum discomfort appropriate for temporary topical relief

Persistent or severe tooth and mouth pain should be assessed by a dentist or healthcare professional rather than repeatedly treated with a topical anesthetic.

What Is Kank-A®?

Kank-A® products are designed for localized oral pain relief.

Benzocaine, the active ingredient in select Kank-A® products, is a topical local anesthetic. When applied to the affected area, it temporarily reduces sensation and helps relieve pain.

Certain Kank-A® formulations also create a protective coating over the irritated area, helping shield it from contact with food, teeth, braces, or other sources of friction.

Maximum-Strength Benzocaine

Select Kank-A® products contain 20% benzocaine, providing maximum-strength topical oral anesthetic action.

Benzocaine may temporarily relieve pain associated with:

• Canker sores

• Minor mouth injuries

• Gum irritation

• Denture irritation

• Orthodontic irritation

• Minor oral burns

Relief is temporary, so the underlying cause should be addressed when discomfort persists or repeatedly returns.

Kank-A® Mouth Pain Liquid

Kank-A® Mouth Pain Liquid combines targeted topical pain relief with convenient application directly to the affected area.

Key Features

• Fast-acting topical anesthetic

• 20% benzocaine in applicable formulations

• Designed for precise application

• Helps reach localized mouth sores

• Convenient for canker sores and minor oral irritation

• Applicator helps minimize direct finger contact

The liquid format can be particularly useful when precise placement on a small or difficult-to-reach sore is needed.

Kank-A® SoftBrush® Tooth & Gum Pain Gel

Kank-A® SoftBrush® provides a portable applicator designed to deliver oral pain-relief gel precisely where it is needed.

Key Features

• Targeted tooth, gum, and mouth pain relief

• Precision SoftBrush® applicator

• Compact, portable format

• Convenient for braces and localized gum irritation

• Helps minimize messy application

Its pen-style design makes it particularly convenient for carrying in a bag, travel kit, or oral-care kit.

Precision, No-Mess Application

Applying oral pain medication directly to a small sore can be difficult.

Kank-A® products are designed with applicators that help improve control:

Mouth Pain Liquid: A targeted applicator helps place the liquid directly onto the affected area.

SoftBrush®: A slender brush-style applicator allows localized application around teeth, gums, braces, and other difficult-to-reach areas.

Always use the specific product exactly as directed on its package.

Canker Sore Support

Canker sores are small, painful ulcers that develop inside the mouth, commonly on the:

• Inner lips

• Inside of the cheeks

• Tongue

• Gums

• Soft tissues around the mouth

They often resolve on their own, but topical anesthetics such as benzocaine can help manage discomfort while the area heals.

Braces & Denture Irritation

Braces, retainers, and dentures can occasionally rub against the soft tissues of the mouth and create painful irritated areas.

Targeted topical relief may temporarily improve comfort, but repeated irritation should also be addressed by your dentist, orthodontist, or denturist so the underlying source of friction can be corrected.

• Follow the labelled frequency and dosage
