Is a fever blister on the lip a cold sore?
A fever blister on the lip is usually a cold sore, while a mouth ulcer or gum blister has different causes and treatment considerations.
What does a cold sore usually look and feel like?
Cold sores often begin with tingling followed by grouped blisters on the lip border. Lesions inside the mouth or beside a painful tooth may be different.
What can you do while a cold sore is active?
Keep it clean, avoid picking, wash hands, and avoid kissing or sharing lip products while active. Ask a pharmacist or clinician about suitable antiviral treatment.
When does a mouth or lip blister need prompt care?
Eye involvement, widespread lesions, severe illness, inability to drink, or a persistent mouth lesion needs prompt care.
What should you ask about a blister in the mouth?
Ask what structure is affected, what caused the symptom, which examination is needed, and which treatment addresses that cause.
Frequently asked questions

Home care can reduce irritation and plaque, but it cannot repair decay, drain an abscess, or correct a broken restoration.
What will the dentist check?
The dentist will examine the relevant tissues, test nearby teeth, and use imaging or measurements when the findings require them.
