What Causes Skin to Shed in the Mouth?
There are several potential reasons why skin sheds or peels off inside the mouth, including:
1. Friction from Brushing or Flossing
The repetitive friction of brushing or flossing can lead to irritation and peeling of delicate oral tissue. Brushing too hard or using a stiff-bristled toothbrush is a common culprit. Flossing vigorously and snapping floss against the gums can also rub away skin.
2. Toothpaste Ingredients
Certain ingredients in toothpaste, like detergents and flavoring agents, can cause mouth irritation and peeling in those with sensitive skin. Common irritating ingredients include sodium lauryl sulfate (SLS), preservatives like parabens, and mint flavors.
3. Canker Sores
Canker sores are small ulcers that develop inside the mouth, often under the tongue or on the gums, cheeks, or lips. Brushing or eating near a canker sore outbreak can disturb the skin and cause temporary shedding and discomfort.
4. Oral Infections
Mouth infections from bacteria, fungi, or viruses can all lead to inflammation, sores, and eventual peeling away of damaged oral tissue. This includes infections like thrush or oral herpes.
5. Dry Mouth
Dry mouth, or xerostomia, reduces protective saliva inside the mouth. This causes irritation, inflammation, and tissue peeling when brushing. Certain medications, aging, and some medical conditions can lead to chronic dry mouth.
6. Contact Allergies
Allergic reactions to substances that contact mouth skin could also be to blame. This includes allergies to ingredients in dental care products, foods, or smoking and chewing tobacco.
7. Autoimmune Conditions
Some autoimmune diseases like lichen planus or pemphigoid can attack mucous membranes and cause blisters or lesions inside the mouth. Brushing near these can worsen the condition.
Tips to Prevent Skin Peeling in the Mouth
Adjusting your oral hygiene routine is the best way to prevent irritation that leads to mouth skin shedding. Try these tips:
Use a Soft-Bristled Toothbrush
Choose an ultra-soft or extra soft bristled toothbrush. This minimizes friction and abrasion to delicate mouth tissue while brushing.
Brush Gently
Avoid aggressive scrubbing when brushing teeth. Use gentle, circular motions to clean teeth and gums without irritating skin.
Floss Carefully
When flossing, be very gentle on areas of skin irritation or inflammation. Use unwaxed dental floss and slide it gently between teeth.
Rinse With Warm Water
Rinsing with warm water can help soothe skin and remove toothpaste residue after brushing. Cold water may shock and irritate already sensitive skin.
Avoid Alcohol and Peroxide Rinses
Mouthwashes containing alcohol or hydrogen peroxide can dry out and aggravate sensitive oral tissue. Use alcohol-free rinses instead.
Apply a Protective Barrier
Coating irritated spots with an oral ointment, gel, or petroleum jelly before brushing may help prevent friction and additional peeling.
Treat Underlying Causes
Addressing issues like infections, dry mouth, or allergies can prevent more extensive oral skin irritation and damage.
Toothpastes for Sensitive Mouth Skin
Switching to a specially formulated toothpaste may also reduce mouth irritation. Look for these ingredients:
Sensodyne
Toothpastes like Sensodyne are designed for sensitive teeth and gums. They avoid harsh irritants and use gentler cleaning agents.
Xylitol
Xylitol is a natural sweetener that can help stimulate saliva flow and remineralize teeth. This helps prevent dry mouth and damage to oral tissue.
Fluoride
Fluoride strengthens enamel and reduces sensitivity that leads to mouth skin irritation. But avoid whitening toothpastes with peroxide.
Calcium
Calcium supplements oral tissue, making it more resilient. This includes options like calcium carbonate or calcium phosphate.
Aloe Vera
Aloe vera gel has soothing properties that relieve inflammation in irritated skin and oral lesions.
Baking Soda
Baking soda balances mouth pH levels to prevent overgrowth of bacteria and fungi that could cause sores or infection.
When to See a Dentist for Skin Peeling
Schedule an appointment with your dentist if you experience:
- Skin shedding that worsens or bleeds over time
- Ulcers or sores that don’t heal within 2 weeks
- Red, swollen, or painful gums
- Sudden increased mouth sensitivity
- Numbness or tingling in the mouth
- Dry mouth, burning sensations, or bad breath
A dentist can examine your mouth tissue, diagnose potential causes, and provide specialized treatment options. For recurring cases, they may recommend seeing an oral medicine specialist.
Professional Treatments for Skin Peeling
Your dentist may recommend these professional treatments to relieve and prevent skin shedding in the mouth:
Medicated Mouth Rinses
Prescription anti-inflammatory rinses like dexamethasone can reduce swollen, irritated tissue. Antiseptic rinses like chlorhexidine may treat underlying infections.
Oral Medications
For autoimmune issues, medications like topical steroids, immunosuppressants, or biologics could reduce lesions and irritation.
Debridement
If skin is extensively damaged, the dentist may want to debride (gently scrape away) the loose tissue to promote healing.
Oral Surgery
For severe cases, oral surgery to remove irritated tissue may be warranted to prevent spreading. This is followed by antibiotics and medicated rinses.
Home Remedies for Mouth Skin Peeling
There are also some natural home treatments that can temporarily relieve mouth skin irritation and promote healing. These include:
Saltwater Rinses
Gargling with warm salt water 2-3 times a day cleans the area and reduces inflammation.
Aloe Vera Gel
Swishing pure aloe vera gel around irritated spots coats and soothes inflamed tissue.
Coconut Oil
Oil pulling by swishing coconut oil helps draw out bacteria from sores while moisturizing dry mouth skin.
Green Tea Bags
Applying cool, damp green tea bags against inflamed mouth skin offers mild anti-inflammatory effects.
When to Seek Emergency Care
Seek emergency medical care if you experience:
- Sudden mouth numbness or inability to speak
- Swelling of the lips, tongue, or throat
- Skin shedding accompanied by fever or fatigue
- Extensive mouth sores or skin loss
- Difficulty eating, drinking, or swallowing
These may indicate a serious allergic reaction, autoimmune condition, or spreading soft tissue infection requiring urgent treatment.
The Takeaway
It's normal for mouth skin to occasionally peel from irritation during brushing or flossing. But chronically sensitive oral tissue could signify an underlying problem. Adjust your dental hygiene routine, use specialized products, and see a dentist to determine the cause and find relief from uncomfortable mouth skin shedding.
FAQs
Why does skin peel off in my mouth after brushing?
The friction and pressure of brushing can rub off skin if you have sensitive oral tissue. Using too much force, a stiff brush, or abrasive toothpaste may cause irritation and peeling.
Is mouth skin peeling a sign of cancer?
Peeling due to occasional irritation is harmless. But chronic mouth sores or skin changes could potentially indicate precancerous lesions. See your dentist to determine the cause.
How can I brush my teeth without peeling off skin?
Use a soft brush and gentle motions. Try a toothpaste for sensitive teeth. Rinse peeled spots with warm water. Apply a protective layer of gel before brushing.
What mouth diseases cause skin shedding?
Oral infections like thrush or herpes can cause mouth sores that peel. Some autoimmune disorders like lichen planus also attack mouth skin and cause lesions.
When should I see a doctor for peeling mouth skin?
See your dentist if the peeling worsens, is accompanied by bleeding or pain, or if ulcers last more than 2 weeks. Severe swelling, numbness, or trouble eating or drinking warrant an urgent care visit.
