Say goodbye to discomfort from mouth ulcers. Get fast relief with Clove Dental’s care.
Struggling with ulcers that don’t heal or return often, affecting your daily comfort?
Most mouth ulcers heal on their own, but non-healing or recurring ulcers may signal underlying conditions, including early signs of oral cancer. At Clove Dental, we provide gentle, targeted care to relieve pain, speed healing, and treat the root cause for lasting comfort.
Mouth ulcers (also called canker sores or aphthous ulcers) are small, painful lesions that develop on the inner cheeks, tongue, gums, or lips. They can make eating, drinking, or even talking uncomfortable - especially when they keep returning or take long to heal.
You should consider seeing a dentist if you:
There are several types of mouth sores and lesions, each with distinct characteristics:
Small, round, painful ulcers inside the mouth. Often triggered by stress, minor injury, or acidic foods.
Caused by accidental bites, braces, sharp teeth, or rough brushing.
White, creamy patches caused by fungal infection, common after antibiotics or in low immunity.
White, lace-like patches or painful sores linked to immune conditions.
White or red patches that don’t heal. These require immediate evaluation.
Ulcers that persist beyond 2–3 weeks, bleed, or appear with lumps should be checked urgently.
Mouth ulcers can appear for many reasons, and their exact trigger isn’t always clear. However, some factors make certain people more prone to developing them. Getting it evaluated helps understand the causative factor better for prompt & effective treatment.
Most mouth ulcers are easy to identify, but when they’re painful, persistent, or keep coming back, a proper evaluation helps determine the exact cause and the safest way to treat them. Here's how dentists typically assess mouth ulcers:
A basic clinical examination is typically sufficient for a healthcare provider to diagnose mouth ulcers. They will assess the lesions’ location, kind, and appearance.
While discussing your case history, your doctor will inquire about any possible triggers or related symptoms. Alongwith medical history the frequency, duration, and severity of your ulcers too helps understand the situation better.
For severe, persistent, or numerous lesions, few more tests are suggested to understand the recurring cause, namely:

Common questions about Mouth Ulcers
Mouth ulcers are painful, shallow sores that form on the soft tissue inside the mouth, inner cheeks, lips, gums, tongue, or floor of the mouth. The most common type (aphthous ulcers/canker sores) is triggered by minor trauma, nutritional deficiencies (B12, iron, folate), stress, hormonal changes, or food sensitivities. They are not contagious and typically heal in 7–14 days.
Mouth ulcers appear inside the mouth, are not infectious, and are not caused by a virus. Cold sores are caused by herpes simplex virus type 1 (HSV-1), appear on the lip border or skin around the mouth, are highly contagious, form fluid-filled blisters before crusting, and tend to recur in the same spot. A dentist can clinically differentiate the two during an examination.
Warm salt water rinses (2–3 times daily) reduce bacterial load and promote healing. Applying honey, pure aloe vera gel, or OTC benzocaine gel provides topical pain relief. Avoiding acidic, spicy, and rough-textured foods prevents further irritation. These measures manage symptoms but do not address underlying nutritional or immune causes of recurring ulcers.
For severe or persistent ulcers, Clove Dental’s dentists prescribe topical corticosteroid paste or gel to reduce inflammation and accelerate healing. Antimicrobial mouthwash prevents secondary bacterial infection. Blood tests are recommended to investigate nutritional deficiencies. Laser treatment is available at many Clove Dental clinics for immediate pain relief and faster ulcer closure.
Recurrent aphthous stomatitis (RAS) is strongly associated with B12, iron, or folate deficiency, Celiac disease, Crohn’s disease, SLE, hormonal fluctuations (particularly in women), and psychological stress. If you experience 3+ ulcers per month, clusters of small ulcers, or ulcers larger than 1 cm, investigation by a Clove Dental oral physician or physician is warranted.
Avoid citrus fruits (oranges, lemons), tomatoes, pineapple, vinegar-based foods, spicy curries, very salty foods, crunchy textures (crisps, toast, raw vegetables), and carbonated drinks. These all irritate the ulcer surface and delay healing. Opt for soft, bland, room-temperature foods until the ulcer has fully re-epithelialised.
