One of the most common medical conditions is oral lesions, which affect one out of every 10 people. Also known as mouth sores, ulcers, or canker sores, these painful lesions often appear as a white-reddish raised spot in the mouth or on the gums, lip, or tongue. While most oral lesions are harmless and go away independently, some may require medical attention.
If you’ve experienced an oral lesion, you may wonder about its cause and if you should see a dentist or doctor for mouth sores. Penn Dental Family Practice explains what you need to know.
Top Questions Answered About White Lesions in the Oral Cavity
What does an oral lesion look like?
Oral mucosal lesions look like small raised ulcers, usually white or gray, and may be surrounded by a red irritated border.
Where Are They Found?
The ulcers are typically found on the soft tissues inside the mouth, such as the inner cheeks, lips, tongue, and gums.
Are They Painful?
Depending on the severity of the condition, they can be painful when speaking, drinking, or eating.
Are Mouth Sores the Same as Cold Sores?
No. While both are types of sores, cold sores (or fever blisters) form around the lips outside the mouth. Cold sores are also contagious, while mouth ulcers are not.
What Causes Mouth Ulcers?
A variety of factors can cause the sores. Some common causes or risk factors include:
- Stress
- Hormonal changes
- Food sensitivities
- Certain medical conditions
These ulcers may also result from minor injuries to the mouth, such as accidental bites or irritation from braces or dentures.
Sometimes, mouth ulcers may be a symptom of an underlying health condition, such as a viral infection or autoimmune disorder.
How Long Do They Last?
They usually last one to two weeks, and you may notice a tingling or burning sensation for a day or two before the spot appears.
How Can You Treat Mouth Sores?
While most ulcers will heal on their own, there are several ways to ease discomfort.
- Avoid hot or spicy foods
- Avoid alcohol and tobacco
- Use over-the-counter pain relievers or numbing drops
- Rinse your mouth with a mild mouthwash or with salt water
- Take an over-the-counter acid reducer
When Should You See a Dentist?
If your oral lesion persists for more than two weeks or is accompanied by other symptoms such as fever, difficulty swallowing, or unexplained weight loss, it is important to see a dental professional. A canker sore dentist can help determine the underlying cause of the lesions and recommend appropriate treatment, which may include prescribing an antibiotic mouthwash or a corticosteroid to place on the sore or take in pill form.
Your dentist may also discuss laser dentistry as a treatment option. This minimally invasive procedure uses a focused beam of light to precisely target and remove the lesion without damaging surrounding tissues.
Sometimes, your dentist may need to perform a biopsy or other tests to diagnose the oral lesions accurately. These tests may involve taking a small tissue sample from the lesion for further examination.
Can You Prevent Oral Lesions?
To prevent oral lesions, good oral hygiene—brushing and flossing regularly, avoiding tobacco products, and consuming a healthy diet rich in fruits and vegetables—is essential. Additionally, managing stress levels and staying hydrated can help reduce the risk of developing mouth sores.
If you are experiencing frequent oral lesions, it is important to consult with your dental professional for proper evaluation and treatment. In some cases, laser dentistry may be used to treat oral lesions effectively and efficiently.
