About the Symptom
Mouth soreness can be due biting your lip, tongue or cheek, trauma to these areas along with the gums and palate, ulcers, gum disease, infection, grinding, clenching, irritation from braces or other orthodontic devices and oral appliances. Your mouth may also be sore from dental visits where you have to keep your mouth open for an extended period of time.
When to See a Doctor
Seek professional care if you experience any of the following symptoms
- Repeated fever above 38 ℃
- Disorder of consciousness
- Fever
Possible Causes
Generally, Sore mouth can be related to:
- Behcet's Disease
A rare autoimmune disease that causes inflammation in blood vessels throughout the body. Symptoms may include mouth and genital sores, as well as eye inflammation. As the disease progresses, joints and internal organs could also be affected.
- Stomatitis
Inflammation of the mouth surface causes ulcers. Various factors can cause this, such as vitamin deficiencies, medications, and autoimmunity (the body's immune system attacking itself). Often, no clear cause is found, and the ulcers heal on their own.
- Candidiasis (Oral, Hands and Feet)
Normal human skin contains bacteria and fungi. Candidiasis occurs when the fungus overgrows and invades the skin. Risk factors include warm moist environments and a weakened immune system.
- Burn/Scald of Roof of Mouth
- Hand, Foot, and Mouth Disease (HFM)
- Pemphigus
- Varicella (Chickenpox)
- Mucous Membrane Pemphigoid
- Herpangina
Related Serious Diseases
Sometimes, Sore mouth may be related to these serious diseases:
- Stevens-Johnson Syndrome / Toxic Epidermal Necrolysis
This serious condition affects the skin and mucous membranes, causing rashes, blisters, and peeling. It can be life threatening. The cause may be a reaction to medication, an infection, or environmental and genetic factors. Those with compromised immune systems are at higher risk.
