Why are Pet Dental Gels Dangerous?
While marketed for pets, some dental gels and toothpastes contain xylitol as a sweetener.
Xylitol is extremely toxic to dogs, causing a rapid and severe release of insulin leading to hypoglycemia (low blood sugar).
It can also cause acute liver failure at higher doses.
Cats are less sensitive to xylitol's effects, but ingestion should still be avoided.
Why speed matters
Delaying care significantly worsens outcomes. Some signs appear hours or days later, so "looks fine right now" is not a reason to wait.
Signs to watch for
- Vomiting
- Weakness, lethargy, or collapse
- Loss of coordination or stumbling
- Tremors or seizures
- Jaundice (yellowing of gums, skin, or eyes)
- Coma
What to do right now
- Call your veterinarian or a pet poison helpline immediately.
- Do NOT induce vomiting unless specifically instructed by a professional.
- If possible, have the product packaging ready to identify the ingredients.
- Your vet will likely check blood sugar levels and provide supportive care, which may include intravenous dextrose and liver protectants.
- Monitor your pet closely for any developing symptoms.
If your pet shows any of the signs above, go to the nearest emergency vet now and call ahead.
