Sore under tongue on bottom of mouth
A sore beneath the tongue may be a traumatic ulcer, a blocked salivary duct, irritation, infection, or another mouth lesion.
What is the direct answer?
A sore beneath the tongue may be a traumatic ulcer, a blocked salivary duct, irritation, infection, or another mouth lesion.
What does this question mean?
Avoid rubbing the area, choose soft foods, keep the mouth clean, and check for sharp teeth or appliances that contact it. A dentist examines the lesion and may assess salivary flow, nearby teeth, lymph nodes, and other oral tissues.
What can you do next?
Arrange review if the sore lasts beyond about two weeks, keeps returning, grows, hardens, bleeds, or causes a neck lump. Rapid floor-of-mouth swelling or trouble swallowing or breathing is urgent.
When should you seek dental care?
Ask what structure is affected, whether trauma or a salivary duct is involved, and how long it should take to heal. Ask whether testing or referral is needed if it persists.
