Sores in your mouth

What Are Mouth Sores?
Mouth sores are painful lesions or ulcers that can form on the gums, tongue, lips, inner cheeks, or roof of the mouth. In some cases, they may even appear around the outside of the mouth—including the nose, lips, or chin.
Most mouth sores are harmless and go away within 7–10 days, but if your symptoms persist or worsen, it’s important to schedule a visit with your local oral health expert in Princeton, NJ.

Common Causes of Mouth Sores

Mouth sores can result from a wide variety of health, lifestyle, and hygiene factors, including:

• - Viral, bacterial, or fungal infections (like herpes simplex or thrush)
• - Trauma or irritation from braces, sharp teeth, dental appliances, or biting
• - Food allergies or sensitivities
• - Hormonal changes, including menstruation and pregnancy
• - Tobacco and alcohol use
• - Poor oral hygiene
• - Vitamin deficiencies, especially B12, iron, or folate

Symptoms of Mouth Sores

Here’s what to look for if you think you may have a mouth sore:

• - Red, white, or yellow ulcers or blisters
• - Swelling and tenderness in the affected area
• - Burning or tingling sensation
• - Pain when eating, brushing, or talking
• - Itching or irritation

Mouth Sore Treatment Options at Dent Blanche Dental

At our state-of-the-art Princeton dental office, we offer a variety of solutions to treat painful mouth sores and restore your comfort:

Topical Relief
We recommend over-the-counter oral gels containing benzocaine or lidocaine for temporary relief from pain and discomfort.

Prescription Medications
Dr. Saad may prescribe antiviral, antifungal, or corticosteroid rinses and ointments depending on the cause of your mouth sore.

 Saltwater Rinses
A natural, at-home remedy: Rinse with warm saltwater 2–3 times daily to soothe inflammation and promote healing.

 Diet Adjustments
Avoid spicy, acidic, or crunchy foods that could irritate the sore further while it’s healing.

 Gentle Oral Hygiene
Use a soft-bristled toothbrush, brush with care, and rinse with an antibacterial mouthwash to keep the area clean and prevent infection.

When to See a Dentist About Mouth Sores

If your mouth sore:

- Lasts more than 10 days

- Becomes increasingly painful

- Is accompanied by fever or swollen glands

- Keeps coming back

- Interferes with eating or speaking

…it's time to schedule a dental exam in Princeton, NJ. Persistent sores may indicate an underlying condition such as autoimmune disorders, nutritional deficiencies, or even oral cancer—and early diagnosis is key.
