Discover the common causes and locations of mouth sores, including medication effects, infections, stress, and injuries. Understanding these factors helps in early diagnosis and effective treatment to maintain oral health.

Many people notice sudden mouth sores that can be quite uncomfortable. These lesions often result from internal factors affecting your health. Recognizing the underlying cause and seeking early treatment is essential to avoid complications. Digestive issues are a common trigger, as stomach problems can cause sores on the tongue and inside the mouth. Possible reasons for mouth sores include side effects from medications, fungal infections like oral thrush due to poor oral hygiene, stress, or injuries from accidental bites or cuts. Knowing where sores occur helps identify potential causes and guides proper treatment.

Medication Effects – Some prescribed treatments can cause mouth sores, which typically resolve after stopping or completing the medication.

Fungal Infections – Poor oral hygiene may lead to oral thrush, resulting in a white coating and painful sores, treated with antifungal medications.

Stress and Injury – Emotional strain or accidental bites and cuts can produce canker sores, lasting from several days to a month. Severe or persistent pain should be evaluated by a healthcare professional.

Location Matters: Sores on the tongue's sides might relate to stress or minor injuries, while sores in other areas could indicate different health issues.
