If you have a mouth sore that is painful, persistent, or unusual in appearance, do not ignore it — early evaluation is critical. Call (561) 735-8750 to schedule your appointment today.
Types of Mouth Sores We Evaluate and Treat
Canker Sores (Aphthous Ulcers)
Canker sores are small, shallow ulcers with a creamy white or yellowish center and a red border that form on the soft tissues inside the mouth — on the inner cheeks, lips, tongue, or at the base of the gums. They are not contagious and are not caused by the herpes virus. Canker sores are often painful and can make eating and speaking uncomfortable, but they typically heal on their own within one to two weeks. Contributing factors include stress, minor mouth injuries, certain foods, hormonal changes, and nutritional deficiencies. Prescription medications or over-the-counter topical treatments can help reduce discomfort during healing. Frequent or unusually large canker sores may warrant evaluation to rule out systemic causes.
Cold Sores (Fever Blisters)
Cold sores are fluid-filled blisters that form on or around the lips — not inside the mouth — caused by the herpes simplex virus (HSV-1). Unlike canker sores, cold sores are contagious and can be spread through direct contact. They often appear in clusters and are typically preceded by tingling, itching, or burning at the site. Common triggers include fever, sun exposure, stress, hormonal changes, and trauma. There is no cure for herpes simplex, but prescription antiviral medications can shorten the duration and reduce the frequency of outbreaks. Patients should avoid sharing personal items during active outbreaks and practice frequent handwashing to minimize spread.
Oral Candidiasis (Thrush)
Oral candidiasis — commonly called thrush — is a fungal infection caused by an overgrowth of Candida yeast inside the mouth. It produces painful red and cream-colored patches on the tongue, inner cheeks, gums, or throat that can bleed when scraped. Thrush is particularly common in denture wearers, people with weakened immune systems, patients recently on antibiotics that disrupt normal oral flora, and individuals using inhaled corticosteroids without proper mouth rinsing afterward. Treatment includes antifungal medications and, where applicable, addressing the underlying predisposing factor.
Leukoplakia
Leukoplakia are thick, white patches that develop on the inner cheeks, tongue, or gums — most commonly in response to chronic irritation from tobacco use, though other causes exist. These patches are typically painless but carry a significant risk of malignant transformation over time. Any white patch in the mouth that does not rub off should be evaluated by a physician. A biopsy may be necessary to determine whether the lesion is benign, precancerous, or malignant. Tobacco cessation is a critical component of managing leukoplakia.
Oral Cancer
Oral cancer can appear as red or white patches, painless ulcers resembling canker sores, or thickened areas on the tongue, floor of the mouth, cheeks, gums, lips, or soft palate. Most oral cancers are squamous cell carcinomas. Risk factors include tobacco use, heavy alcohol consumption, and HPV infection. Oral cancer is most common in adults over 45 but can occur at any age. When detected early, oral cancers are typically highly treatable. When they spread — usually to lymph nodes in the neck — treatment becomes significantly more complex and outcomes less favorable. This is why any mouth sore or unusual oral lesion that does not heal within two to three weeks should be promptly evaluated by an ENT physician like Dr. Brodner at The Center for Sinus, Allergy, & Sleep Wellness.
Frequently Asked Questions About Mouth Sores
What is the difference between a canker sore and a cold sore?
Canker sores are non-contagious ulcers that form inside the mouth on soft tissue such as the inner cheeks, tongue, or gum line. They are not caused by a virus. Cold sores are contagious, fluid-filled blisters caused by the herpes simplex virus that typically appear on or around the lips — on the outside of the mouth. Canker sores heal on their own in one to two weeks; cold sores are managed with antiviral medications but recur throughout life.
When should a mouth sore be evaluated by a doctor?
Any mouth sore that does not heal within two to three weeks, grows in size, becomes increasingly painful, bleeds without provocation, or is associated with difficulty swallowing, speaking, or moving the jaw should be promptly evaluated by an ENT physician. These characteristics may indicate a more serious condition including oral cancer. Call (561) 735-8750 to schedule an evaluation at The Center for Sinus, Allergy, & Sleep Wellness — do not wait on a non-healing oral lesion.
Can tobacco use cause mouth sores?
Yes. Tobacco use — including cigarettes, cigars, pipes, and smokeless tobacco — is one of the primary risk factors for leukoplakia (thickened white patches) and oral cancer. Tobacco users who notice white patches, sores, or unusual thickening in the mouth should be evaluated promptly. Cessation of tobacco use is both the most important preventive measure and the first step in managing tobacco-related oral lesions.
What is oral thrush and who is at risk?
Oral thrush is a fungal infection caused by Candida yeast that produces painful white and red patches inside the mouth. It is most common in people with weakened immune systems, those recently on antibiotics, denture wearers, and individuals using inhaled corticosteroids. Treatment involves antifungal medications and addressing the underlying predisposing factor. If you develop oral patches or persistent mouth pain in Boynton Beach, FL, contact The Center for Sinus, Allergy, & Sleep Wellness at (561) 735-8750.
What does oral cancer look like?
Oral cancer can appear as a painless white or red patch, a small ulcer that resembles a canker sore but does not heal, a lump or thickening in the cheek or on the tongue, or persistent soreness in the throat. It most commonly develops on the tongue, floor of the mouth, or inner cheeks. Because early oral cancer is often painless, patients may not seek evaluation until the lesion is more advanced. Regular oral self-exams and prompt evaluation of any unusual or persistent oral lesion are the most important early detection strategies.
Is a biopsy required for all mouth sores?
No — not every mouth sore requires a biopsy. Common, clearly benign lesions like canker sores or cold sores are diagnosed clinically. However, white patches (leukoplakia or erythroplakia), non-healing ulcers, or any lesion with concerning features requires biopsy to definitively establish the diagnosis and rule out malignancy. Dr. Brodner performs a thorough clinical examination and determines whether biopsy is indicated based on the appearance and behavior of the lesion.
Can mouth sores be related to ENT conditions like sinusitis or post-nasal drip?
In some cases, yes. Chronic post-nasal drip can cause throat irritation and occasionally contribute to soreness at the back of the mouth or throat. Acid reflux (LPR) — which frequently coexists with sinus and throat symptoms — can cause painful irritation of the soft tissues in the back of the mouth and throat that may be mistaken for recurring mouth sores. Dr. Brodner evaluates patients holistically to identify all contributing ENT factors.
