Why is the Inside of My Cheek Peeling? Causes & Prevention

Understanding Cheek Peeling in the Mouth

It can be uncomfortable and concerning when the delicate skin on the inside of the mouth starts to peel. This irritation is often caused by simple factors like acidic foods or aggressive brushing. Other times, persistent cheek peeling can indicate an underlying condition. Learning what triggers cheek peeling and how to prevent further irritation is key.

Common Causes of Inner Cheek Peeling

Some of the most common culprits of inner cheek peeling include:

• Spicy, acidic, or salty foods
• Aggressive brushing with a stiff toothbrush
• Ill-fitting dentures or braces
• Canker sores
• Oral lichen planus
• Certain ingredient sensitivities

Foods with sharp edges like chips or crackers can also scratch and irritate the inside of the mouth. And ingredients in toothpastes, mouthwashes, or dental treatments may trigger a reaction in some people.

Acidic Foods and Abrasive Brushing

Two of the most common causes of cheek peeling are acidic foods and overly-aggressive brushing.

Foods and drinks like citrus fruits, tomatoes, and soda have high acid content. This acid can erode and irritate the thin, delicate mucosal lining of the mouth, leading to peeling and discomfort.

Likewise, scrubbing too vigorously with a stiff-bristled toothbrush or abrasive toothpaste can wear away at the tissue lining the mouth.

This irritation is often temporary if the trigger is avoided. The mouth has a remarkable ability to heal itself, quickly replacing damaged cells once the irritation is removed.

Ill-Fitting Dental Work and Canker Sores

Sometimes cheek peeling is caused by physical abrasion from braces, dentures, retainers, or other dental work rubbing against the inside of the mouth.

Canker sores - small ulcers that develop on the soft tissues of the mouth - can also lead to cheek peeling. Canker sores have many potential triggers, including:

• Stress
• Hormonal changes
• Nutritional deficiencies
• Oral trauma or irritation
• Food sensitivities
• Immune system reactions

As canker sores heal and new skin forms, the tissue lining the mouth can temporarily peel.

Oral Lichen Planus

A condition called oral lichen planus sometimes causes chronic cheek peeling and discomfort. This disease involves an overgrowth of cells along with inflammation in the mucosal tissues.

Oral lichen planus tends to come and go, with periods of symptom flare-ups. It produces painful lesions and tissue damage inside the mouth, leading to a raw, irritated feeling.

Doctors aren’t entirely sure what triggers oral lichen planus. Contributing factors may include:

• A misdirected immune response
• Genetic predisposition
• Reaction to certain medications
• Hepatitis C infection
• Excess stress

Managing oral lichen planus involves using topical numbing creams or gels to ease discomfort until the flare-up passes.

Toothpaste Ingredient Sensitivity

Although rare, some people develop contact allergies or sensitivities to ingredients in oral hygiene products like toothpaste, mouthwash, or dental treatments.

Potential irritants include sudsing agents like sodium lauryl sulfate and flavoring agents. If a product seems to consistently cause cheek peeling and discomfort, switching to a simpler, fragrance-free brand may help.

Preventing Further Cheek Irritation in the Mouth

Once you identify what’s causing cheek peeling in your mouth, avoiding or managing the trigger is key. Some tips to prevent irritation include:

Go Easy When Brushing

Use a soft-bristled brush and be careful not to rub too hard on the cheeks or other mouth tissues while brushing. This minimizes abrasion and irritation in the sensitive mouth area.

Rinse After Spicy/Acidic Foods

After meals, rinse your mouth with water to neutralize and wash away traces of acidic foods and spices. This prevents chronic irritation and tissue damage.

Treat Oral Health Problems

If underlying issues like ill-fitting dentures, canker sores or oral infections are causing cheek peeling, get prompt treatment to resolve these problems.

Apply Coatings/Barriers

Dentists can prescribe medicated mouth gels that coat and protect irritated areas in the mouth, allowing them to heal. These numbing gels and pastes essentially create a temporary barrier shielding raw tissues.

Improve Nutrient Intake

Consuming a balanced, whole food diet helps ensure the mouth gets nutrients needed to maintain tissue integrity and heal injuries.

Vitamin C promotes collagen production for faster wound closure. Vitamin B12, iron, folate and zinc also encourage oral tissue repair.

Quit Smoking and Limit Alcohol

Chemicals in tobacco can irritate mouth tissues, delaying healing. And excess alcohol tends to irritate the sensitive mouth lining.

Seeking Professional Care for Persistent Cheek Peeling

Although cheek peeling causes temporary discomfort, the mouth usually recovers quickly once irritants are removed. So implementing preventive strategies is often enough to find relief.

But if cheek irritation and sloughing lasts longer than two weeks or frequently returns, seeking medical care is wise.

A dentist can diagnose damaging habits, fit dental appliances, provide medicated rinses or pastes, and rule out serious conditions causing the peeling. Skin disorders, autoimmune diseases and even vitamin deficiencies may sometimes be behind chronic cheek irritation.

Figuring out any underlying condition and developing an effective treatment plan helps minimize frustrating cheek discomfort over the long-term.

And never ignore symptoms like worsening pain, swelling, ulcerations or difficulty eating/talking as these can indicate a more serious issue requiring prompt medical care.
