Tongue Sores and Oral Cancer
A sore tongue accompanied by ulceration is a classic symptom of oral cancer. Where the sore on tongue appears is important to the diagnosis. Oral cancer rarely develops on the top of the tongue unless the disease occurs in conjunction with untreated syphilis. A persistent sore under tongue or a hard, painless bump that develops on only one side of the tongue are more troubling symptoms that should be examined by a dentist DDS, DMD or oral surgeon as soon as possible.
Tongue Sores Treatment Plan
In many instances, tongue sores will heal by themselves over the course of one or two painful weeks. To reduce discomfort in the meantime, you should consider eating bland foods, rinsing frequently with warm water and applying pain-relieving gels on the sores
Since mouth and tongue sores are closely associated with several life-threatening health conditions, it's important to monitor them closely. See a dental specialist immediately if you're experiencing mouth and tongue sores for the first time. Other warning signs to watch out for include sores that fail to heal within two weeks, sores larger than one centimeter across, an increase in the frequency outbreaks, and sores accompanied by other symptoms, (e.g. rashes, diarrhea, joint pain, fever, etc.).
