Is Your Mouth Sore Common or Something More?

Mouth sores, like inflame­d taste buds or gross-look­ing lip irritations, are common. But, how do we know if something is a serious condition or just a common malady. If a sore in your mouth doesn’t heal within two weeks, consider seeing a dentist. Sores in the mouth are easy entry points for germs and viruses, which makes them good breeding grounds for infections and other health issues. This can lead to periodontal diseases that can be extremely costly, and painful to repair.

If you’re a smoker, drinker, chemotherapy patient, or have a weak immune system, you should also get regular oral screenings from a dental professional. One of the first signs of oral cancer is a mouth sore that doesn’t heal. Other symptoms of oral cancers include sores on your tongue, lumps or masses in your throat, pain or difficulty swallowing or speaking, a sore or lump in your neck, hoarseness in your voice, or numbness in your face.
