🔍 What Is Bruxism?
Bruxism refers to the grinding or clenching of teeth, often heard as scraping or grinding noises when the cat moves its jaw—especially while eating or chewing. It typically signals underlying pain, most often dental or gastrointestinal in origin :contentReference[oaicite:3]{index=3}.
🧭 Common Causes
- Dental diseases: Tooth resorption, gingivitis, ulcers, cavities, fractured teeth, or oral tumors—pain from these drives grinding :contentReference[oaicite:4]{index=4}.
- Malocclusion: Misaligned teeth or jaws—especially in brachycephalic breeds like Persians and Siamese—can lead to grinding from abnormal friction :contentReference[oaicite:5]{index=5}.
- GI discomfort: Nausea, acid reflux, ulcers, pancreatitis, IBD—cats may grind to cope with visceral pain :contentReference[oaicite:6]{index=6}.
- Stress or anxiety: Emotional distress can trigger grinding in sensitive cats :contentReference[oaicite:7]{index=7}.
- Neurologic or systemic pain: Conditions like arthritis or nerve pain may manifest as bruxism :contentReference[oaicite:8]{index=8}.
⚠️ When to Worry—Red Flags
- Persistent grinding sounds, especially with other signs
- Pain indicators: drooling, pawing at mouth, head shaking, head tilt
- Eating changes: dropping food, avoiding hard food, reduced appetite
- Behavioral changes: lethargy, hiding, stress signs
- Secondary effects: tooth wear, jaw pain (TMJ), bleeding, facial swelling
