- Inflammation of mucous lining of any of the structures in the mouth, cheeks, lip, tongue, gingiva, and floor or roof of the mouth. Usually painful and associated with redness, swelling, and sometimes bleeding. Affects people of all ages. May be caused by localized injury/irritation, or a manifestation of systemic conditions
- System(s) affected: skin/exocrine; ENT; oropharynx; dental
- Primary herpetic infections (age 6 months to 5 years) (most common)
- Hand-foot-mouth disease, herpangina
- Angular stomatitis
- Aphthous stomatitis
- Teenagers and adults
- Aphthous stomatitis (peak onset age 10 to 19 years) (most common)
- Vincent stomatitis (also known as Vincent disease or acute necrotizing ulcerative gingivitis)
- Behçet disease (orogenital lesions)
- Nicotinic stomatitis
- Chronic ulcerative stomatitis (white middle-aged women)
- Very common: herpetic stomatitis, hand-foot-mouth disease, and recurrent aphthous stomatitis (RAS)
- Common: herpangina, nicotinic stomatitis, and denture-related stomatitis
- Remaining causes are uncommon or rare.
Etiology and Pathophysiology
- Allergy: foods, drugs, contact (some erythema multiforme)
- Nutritional deficiencies: vitamin B6 (angular stomatitis), vitamin B12, folate, zinc, magnesium, vitamin C, iron deficiencies
- Malnutrition (gangrenous stomatitis; internationally known as “noma”)
- Viral: herpes simplex I and II (herpetic stomatitis), coxsackie A (herpangina and hand-foot-mouth disease)
- Bacterial (scarlatina)
- Autoimmune disorders (Crohn, Behçet, SLE, celiac, erythema multiforme)
- Neoplastic/hematologic (anemia, leukemia, cyclic neutropenia)
- Smoking (nicotinic stomatitis)
- Hormonal (possibly RAS)
- Uncertain (RAS, Vincent stomatitis, recurrent scarifying stomatitis)
- Traumatic: (mechanical, chemical, or thermal) for example, ill-fitting dentures
- Uremic (uremic/nephritic)
- Chemotherapy or radiation
- Poor oral hygiene
- Familial association
- Dietary deficiencies (iron, folate, vitamins B6, vitamins B12)
- Chronic systemic disease; immune deficiencies
- Poor-fitting dentures
- Cancer therapies
- Avoid causative factors (see “Etiology and Pathophysiology”).
- Herpetic stomatitis; shedding may occur for 2 weeks for primary infection, 60 hours for recurrent infection.
- Good oral hygiene
- Good nutrition: Daily multivitamin does not reduce RAS episodes (4)[B].
- Avoid/discontinue smoking.
- Properly fitting dentures
Common causes in the pediatric population (e.g., herpetic [primary], hand-foot-mouth disease, herpangina, traumatic ulcers)
Certain etiologies are more likely in the geriatric population (e.g., ill-fitting dentures, nutritional deficiencies).
Commonly Associated Conditions
- Pregnancy may bring on recurrent ulcerative stomatitis.
- AIDS: associated with multiple, severe oral lesions
- Aphthous ulcers may be associated with Crohn disease or celiac disease.
- Patient will complain of burning sensation, intolerance to temperature, and irritation with certain foods.
- Detailing the onset, progression, and duration of each lesion helps to diagnose localized versus systemic lesions.
The physical exam should include comprehensive oral examination. Examine and palpate the lips, tongue, cheeks, and hard and soft palate as well as cervical, submandibular, and submental lymph nodes. Erythema and edema are the usual oral manifestations, often with ulcerations. Some will have constitutional symptoms: low-grade fever, malaise, lymphadenopathy, and headache. Pain will vary. Below is a list of specific characteristics:
- Allergic stomatitis
- Intense shiny erythema
- Slight swelling
- Common allergens include nuts; shellfish; cinnamon; fruits; metals; dental materials; and ingredients in toothpaste, mouthwash, and gum.
- Herpetic stomatitis
- Same as allergic stomatitis; may have low-grade fever and easy bleeding
- Same as allergic stomatitis; often multiple lesions
- Vincent infection: necrotic ulceration of interdental papillae and mucous membrane
- Pseudomembranous stomatitis: membrane-like exudate
- Mucous lesions accompanying systemic disease
- Mucous patches (syphilis)
- Strawberry tongue (Kawasaki disease, scarlet fever, staphylococcal toxic shock syndrome)
- Koplik spots (measles)
- Ulcers (erythema multiforme)
- Smooth, fire red, painful (pellagra)
- Varicella zoster
- Hand-foot-mouth disease, herpangina
- RAS (note: can be associated with colitis)
- Erythema multiforme/Stevens-Johnson syndrome
- Behçet disease
- Angular stomatitis
- Noma (gangrenous stomatitis)
- Scarlatina (scarlet fever)
- Cancers of oral mucosa
- Uremic stomatitis
- Reactive arthritis
- Squamous cell cancer
- Cyclic neutropenia
- Burning mouth syndrome
- PFAPA (periodic fever, aphthous ulcers, pharyngitis, and adenopathy)
Diagnostic Tests & Interpretation
- Diagnosis relies on clinical symptoms and history. Testing is not routinely performed.
- Usually none needed; consider the following for differential diagnosis:
- Tzanck test of historic interest only; herpes simplex virus (HSV) culture (from vesicles)
- Serologic test for syphilis
Initial Tests (lab, imaging)
If not resolving in 7 to 14 days or getting worse, consider CBC; cultures to determine secondary infection
- Biopsy if persistent/recurrent/suspicious
- Direct fluorescent antibody testing is useful in the differential diagnosis between RAS and bullous skin diseases (5)[B].
Biopsy suspicious lesion or lesions that fail to heal or chronically recur to rule out oral granulomatosis, tuberculosis, hematologic cancer, or vasculitis.
- To date, no strong evidence for broadly applicable efficacy of a single treatment. This likely reflects the poor methodologic rigor of trials and lack of studies rather than the true effect of the intervention. It is also recognized that, in clinical practice, individual drugs appear to work for individual patients (3)[A].
- Treatments target the causative factors. If cause is allergic, identification and removal of allergen is critical. For infectious causes, regimens include antibiotics or antifungals. Steroidal anti-inflammatory drugs used for systemic conditions with stomatitis manifestation. If the cause of stomatitis is due to medical treatment or cancer therapy, management needs to be more aggressive (5)[A].
- In most cases, treatment of symptoms only, analgesics
- Severe cases may require parenteral fluids, particularly in children.
- Good oral hygiene
- Topical anesthesia
- Oral rinses such as half-strength hydrogen peroxide, chlorhexidine gluconate. Avoid oral rinses containing alcohol.
- Smoking cessation
- Refit dentures; daytime wear only
- Avoid specific allergens.
- Replace vitamin deficiencies.
- Treat malnutrition, if present.
- Acetaminophen or ibuprofen for analgesia
- Steroids, colchicine, and cytotoxic drugs for Behçet disease
- 2% viscous lidocaine (Xylocaine) swish and spit for local discomfort; max of 8 doses/day
- Precautions: Toxic dose of topical lidocaine is uncertain, but likely only 25–33% of dose may have significant absorption from open ulcers or mucous membrane.
- Liquid diphenhydramine (Benadryl) by mouth or swish and spit, for allergic reactions
- “Miracle mouth rinses”: various combinations of the following in equal parts; use swish and spit QID
- Maalox or Mylanta, diphenhydramine, lidocaine
- Maalox or Mylanta, diphenhydramine, Carafate
- Duke’s: nystatin, diphenhydramine, hydrocortisone
- Steroid oral rinses or topical preparations for aphthous ulcers (Kenalog in Orabase) or steroids injected into lesions for severe cases
- Antibiotics for gangrenous stomatitis (penicillin and metronidazole are reasonable first-line agents; often start with IV)
- Acyclovir 200 to 800 mg 5 times per day for 7 to 14 days for herpetic stomatitis
- Sucralfate (Carafate) suspension 1 tsp swish in mouth or place on ulcers QID (helpful)
- Topical 0.2% hyaluronic acid for recurrent aphthous ulcers
- Chemical cauterization with silver nitrate for aphthous stomatitis (treatment can cause burning sensation)
- Thalidomide 200 mg 1 to 2 times per day for 3 to 8 weeks in HIV-positive patients with nonhealing aphthous ulcers (extreme caution for birth defects)
- For candidiasis: nystatin PO suspension 400,000 U (4 mL) QID for 10 days; swish and swallow (1 mL QID for infants)
- Antifungal ointment (e.g., nystatin [Mycostatin]) for candidiasis-complicating angular stomatitis
- For prevention or reducing severity of mucositis with cancer treatments, these agents have some evidence of benefit: allopurinol, Aloe vera, amifostine, cryotherapy, glutamine (IV), honey, keratinocyte growth factor, laser, and polymyxin/tobramycin/amphotericin (PTA) antibiotic pastille/paste (6)[A].
- Contraindications: allergy to specific medication
Complementary and Alternative Medicine
- Avoiding toothpaste with sodium lauryl sulfate reduces duration of RAS (7)[B].
- Replenish vitamin deficiencies.
In severe cases involving dehydration owing to oral ulcerations
For infants with painful stomatitis, feeding can be particularly challenging. Topical analgesic agents should be used prior to bottlefeeding. Nasogastric feeds or parenteral, as needed
Lesions need to be followed until resolved. Biopsy if they fail to resolve, continuously recur, or appear suspicious.
Avoid spicy, acidic, sharp, hard, and dry foods. Keep well hydrated.
