Our mouths can reveal hidden health problems. As the article states, *“Many diseases and deficiencies can manifest themselves through oral symptoms before they appear elsewhere in the body.”* Being alert to changes in your mouth can lead to early diagnosis and better health.

**Swollen or Bleeding Gums**
Bleeding when brushing may point to *“gingivitis, periodontitis, vitamin C deficiency, or diabetes.”* Don’t ignore these signs.

**Mouth Sores and Bad Breath**
Persistent canker sores could signal *“stress, vitamin B12 deficiency, or autoimmune diseases.”* If they last more than two weeks, see a doctor. Chronic bad breath might mean *“gum infections, digestive issues, or kidney problems.”*

**Tongue and Lip Changes**
A *“white-coated tongue”* may indicate a fungal infection or dehydration. A red or black tongue could signal vitamin issues or poor hygiene. Constantly *“dry and chapped lips”* might result from dehydration, allergies, or vitamin B2 deficiency.

**Tooth Sensitivity**
Pain from hot or cold drinks may be caused by *“enamel wear, cavities, gum disease, or nerve problems.”*

Oral health is more than clean teeth—it’s a mirror of your overall condition. If symptoms linger, get medical advice.
