Do buns teeth stop growing when they get old?

Charlie is 10 and has quite a few health issues - calcium intolerant since he was 3, he had E.C 2 years ago which has left him slightly tilted, he has an abcess in his jaw bones and is generally getting old.

We do our best with his food but nowadays its a case of getting him to eat anything is a success (we've actually got him to put on some weight!) so daily he has a few science selective pellets sprayed with water, a few beaphar high calorie pellets sprayed with water, oats, hazelnuts, peas, coriander, grapes, strawberries, green beans and tender stem brocolli. ie its high in sugar and all a bit soft. I've not seen him eat hay for many months.

He goes to the vet every few weeks and always has his teeth checked and they're fine. I can't understand how they're fine when he's not eating anything to grind them down?! Do their teeth stop growing when they get old?

Also, his front ones are looking dirty, they've got brown stuff on them which you can scrape off. I'm wondering about cleaning them. I assume this is plaque cos of the sugar in the fruit and probably something to do with medicine he has to have (paediatric septrin twice a day and meloxydryl once). I'm sure they wouldn't have chance to get this brown if they were growing as quickly as they should be. Any ideas?

10 yrs old Wow! :thumb:

I'm definitely no expert on elderly buns so I hope one of the more experienced elderly bunny keepers will be along shortly to help.....but as far as i'm aware in lagomorphs ALL teeth grow continuously throughout life. I wonder however if when metabolism slows due to age that bone and tooth formation, doesn't stop, but also slows correspondingly? and therefore tooth root eruption is to a point reduced? Grinding fibrous green stuff will have some dental wear benefit - anything that produces a side-to-side chewing motion - obviously hay/grass is more effective but I can understand that just getting him to eat is a struggle and i'm glad he is still eating
Not sure about the tooth staining - i'm sure someone else will have some ideas...perhaps it is also related to tooth root eruption rate and therefore the teeth you see are just older??
I hope my bunnies live this long .....:wave:
