Thank you Evelyn, very much appreciate your thoughts.. As to equipment, I'm not 100% sure - its very new and provided by iM3 - looking at their website it looks like a Revolution 4DC with CR7 plates/software - lovely to use, still getting the hang of positioning, especially cat upper arcades.  

In relation to this cat, I did exactly as you said with 107, felt the same about 209 but left it as no gingivitis.  I was unsure about 304, I thought the root was resorbing but there were no issues on probing so I warned the owner this tooth may cause a problem in future and left it in place for today, and gave a good subgingival scale as there was a little more gum recession on this side.

No gingivitis over sites of lost 307/407 so left.

309 I felt the extent of root resorption and the moth eaten appearance in the centre  of the tooth justified extraction, which was mainly crown amputation (post extraction rads were taken and looked ok - just not posted here).  409 I didn't think looked quite as bad, I felt the roots were more visible although heading towards resorption, and again no gingivitis or lesions on probing - so like the canine I advised close monitoring, with a warning that this one is likely to cause problems in future.  With hindsight and longer to review rads, maybe this one should have come out today also although surgically unlike the others as still roots to remove.

I wasn't too concerned about movement in the symphysis, only really if one or both of the lower canines needed to come out in future to note it was present before I started the extraction rather than being as a result of it!

I spoke to the owner post rads/pre extractions to explain my plan, in case they were keen to have 304/409 out now to avoid another procedure further down the line but they were happy to monitor those and most of our vaccinated animals take up a free 6 month health check option which is very useful for this purpose.
