Noticing an unusual bump under your tongue, a sore on your lip, or a swelling on your gums can be worrying. While many mouth lesions are harmless and temporary, some may indicate an infection, a dental problem, or another condition that requires professional attention.
Understanding the different types of mouth lesions, recognizing warning signs, and knowing when to seek medical care can help you protect your oral health.
Step 1: Recognize the Different Types of Mouth Lesions
Mouth lesions can appear in several forms. Their appearance, location, duration, and associated symptoms can provide useful clues about their possible cause.
1. Swelling Under the Tongue
A lump beneath the tongue may develop for several reasons, including:
- Blocked salivary gland: A small stone or blockage can prevent saliva from flowing normally, sometimes causing swelling or discomfort.
- Mucocele or ranula: These are fluid-filled swellings that can develop when saliva collects beneath the oral tissues.
- Infection: Inflammation involving the salivary glands or nearby tissues may cause pain, tenderness, or swelling.
- Other oral growths: Some lumps develop from benign tissue changes, although persistent or unusual lesions require examination.
A swelling beneath the tongue should not automatically be assumed to be harmless. A dentist or doctor can determine whether further investigation is necessary.
2. White or Painful Sores on the Lips
Small, round sores on the inner lips or inside the mouth may be canker sores, also called aphthous ulcers.
Common characteristics include:
- A white or yellowish center.
- A red border.
- Pain when eating, drinking, or speaking.
- Sensitivity to acidic, salty, or spicy foods.
Canker sores are not contagious and often heal within one to two weeks.
However, sores on the outer lip may have a different cause. Cold sores, for example, are commonly associated with the herpes simplex virus and may begin with tingling or burning before small blisters appear.
The location and appearance of a lesion can help distinguish these conditions, but a professional assessment may be necessary when the diagnosis is uncertain.
3. Bumps on the Gums
A raised bump on the gum may be caused by irritation, a benign growth, or a dental infection.
Possible causes include:
- Dental abscess: A collection of pus caused by a bacterial infection involving a tooth or surrounding tissues.
- Gum inflammation: Irritation or infection affecting the tissues around the teeth.
- Fibroma: A benign lump that may develop in response to repeated irritation.
- Other oral lesions: Some growths require examination to determine their nature.
A gum bump accompanied by toothache, pus, a bad taste, facial swelling, or fever may indicate an infection.
A suspected dental abscess requires urgent dental treatment. Do not squeeze, puncture, or attempt to drain the bump yourself.
