I've been thinking about Mazy cat and her FORL. The only other cat who was ever diagnosed with resorptive lesions was Tolly.
Both had frequent vomiting episodes most of their lives. Mazy cat, as most of you know was on a terrible diet for 6 years which has caused all her digestive issues and is directly related to her poor motility and frequent regurgitation.
And now, at 11 years old she presented with 4 resorptive lesions, two which had been there long enough for the teeth to have been mostly already reabsorbed.
Tolly's was not diet related, but he had also had motility problems possibly brought on by his life time phenobarbital use. He didn't regurgitate, he was on a wet diet all his life, but he had terrible trouble with ingested fur. His fur would just (my theory based on many things) coat his insides until it was so built up he couldn't eat at all until he passed it. Then he would have these three or four day long episodes of vomiting (I would give him sub q, and heaven help me large doses of laxatone), until he finally would start pooping out the fur. And that is ALL it would be, when it came out, just all this red fur. Then he would be fine until the next episode.
Baby, fed a wet diet all his life, never had any dental problems, that I know of. Sissy did, and she was fed a dry diet until she came to live with me at five years old. Bibbs had a bit of a scarf and barf (wet diet) habit, and she did need a dental when she was 13 (I don't know if she had FORL or not, the vet never mentioned it but she was not a good vet). Ootay hardly ever vomited until she became CKD, she didn't have a dental until she was 17. She did not have FORL.
Thing is, chronic puking, whether it's regurgitation or empty tummy, or hairballs, is rough on the teeth. The acid eats away at the enamel, and I suspect now, under the gum at the root.
