Do herpes sore be under the tongue on gum?

Yes, herpes sores can occur under the tongue or on the gums. These sores are typically caused by the herpes simplex virus type 1 (HSV-1), which is the same virus that causes oral herpes or cold sores. When HSV-1 infects the tissues in the mouth, it can lead to the formation of painful blisters or ulcers. These sores can appear on the tongue, inside the cheeks, on the gums, or even on the roof of the mouth. They usually begin as small, red bumps that eventually rupture and form open sores. Herpes sores in the mouth can be recurrent, meaning they can reappear periodically throughout a person's life. If you have a sore under your tongue or on your gums that you suspect may be a herpes sore, it's important to see a healthcare professional for proper diagnosis and treatment.
