Why are my 5-year-old cat's teeth falling out and breath bad?

Hello, i have a concern about my cats teeth. She’s about 5 years old and 3 out of 4 of her fangs have fallen out. For the first two I wasn’t home but they fell out at separate times and this morning the third one fell out and I was wondering if it was because of plaque and tar buildup because she also has bad breath so bought a cat tooth brush to test out if it will help a little before going to the actual vet

Poor Ellie! It sounds like she has severe dental disease if her teeth are falling out. This is not normal, and it does indicate bad plaque and tartar buildup. Brushing her teeth at this point will not help, she has to see a vet for this problem. She may have more teeth that need to be removed, and the rest of her teeth need to be cleaned, scaled, and polished. Please call her vet on Monday to make an appointment for her.
