Aphthous Ulcer

Overview

What is an Aphthous Ulcer on the Gums?

Aphthous ulcers (canker sores) on the gums are painful, round or oval shallow ulcers that can develop on the gingival tissue. They appear as white or yellow lesions with a red border and heal within 1-2 weeks.

• Common oral mucosal condition
• Painful shallow ulcers
• Not contagious
• Usually heal within 1-2 weeks
• May be recurrent in some individuals

Overview of the Condition

Aphthous ulcers can occur on any non-keratinized oral mucosa, including the gingiva. When on the gums, they may be particularly painful and can interfere with oral hygiene. They are benign and self-limiting.

Symptoms and Causes

Symptoms

• Painful round or oval ulcer on gum
• White or yellow center with red halo
• Burning or tingling before ulcer appears
• Pain with brushing and eating
• Usually 3-10mm in diameter
• May make oral hygiene difficult
• Heals without scarring (minor type)

Causes

• Exact cause unknown
• Minor trauma (aggressive brushing, dental work)
• Stress
• Hormonal changes
• Nutritional deficiencies (B12, iron, folate)
• Food sensitivities
• Toothpaste ingredients (SLS)
• Immune system factors

Diagnosis and Treatment Options

Diagnosis

• Clinical examination
• Characteristic ulcer appearance
• Patient history of recurrence
• Differentiation from other gingival lesions
• Blood tests if frequent or severe

Treatment Options

• Topical anesthetics for pain
• Topical corticosteroid gels
• Antimicrobial mouthwashes
• Protective pastes
• Vitamin supplementation if deficient
• Most heal without specific treatment

Non-Surgical Care

Conservative Management

Most gingival aphthous ulcers heal spontaneously within 1-2 weeks. Treatment focuses on pain relief and avoiding further irritation. Maintaining oral hygiene is important despite the discomfort.

Home Care Recommendations

1. Rinse with salt water or baking soda solution
2. Apply topical pain-relieving gel
3. Avoid spicy and acidic foods
4. Brush gently with soft brush
5. Consider SLS-free toothpaste
6. Maintain hydration

Surgical Care

When is Surgery Needed?

Surgery is not indicated for aphthous ulcers. Chemical cauterization or laser can provide rapid pain relief for severe cases. Biopsy is considered if ulcers don't heal within 3 weeks.

Anatomy and Affected Areas

Anatomy Overview

Aphthous ulcers typically affect non-keratinized mucosa. On the gingiva, they usually occur on the alveolar mucosa or unattached gingiva rather than the attached (keratinized) gingiva.

Common Gingival Locations

• Alveolar mucosa
• Unattached (free) gingiva
• Less common on attached gingiva
• Vestibular fold area
