[quote user="Kate Richardson"]You have to remember Arlo Guthrie that for a certain demographic of members (of which I am sure GrooveJet wont mind me including ) even uploading a photo is an achievement and can sometimes take us half a day to figure out how to do it.

You hit the button on the nose Kate!

Rachel won't mind me saying that I love that word "idiopathic".

It cropped up in another thread recently, the calcinosis cutis one I think.

GrooveJet - a couple of tips ... if you post images using the image icon in the text editor, it displays the image within the forum post (as opposed to being an attachment), which I always think works better.

Also, that first image was huuuuuge! That's fine, but if you are uploading from a desktop, it is best if you can resize a bit smaller, because it will load quicker.

I've done it for you here.

It looks like replacement resorption, which is quite common in middle to older age dogs. Tooth resorption has been described in dogs:https://avmajournals.avma.org/doi/abs/10.2460/ajvr.71.7.784

This type is idiopathic, but seems to be more common in an ageing population. Resorption is driven by the odontoclasts which are switched on now and then in life (e.g. during deciduous tooth shedding, or when there is damage to a root surface, and necrotic cementum needs to be tidied up_) but should then be switched off again. In this type of resorption, things seem to go a bit haywire, with massive removal of dental tissues, and replacement by bone. You could hypothesise in this dog that his oral behaviours may have contributed , but that is pure speculation.

Anyway, what to do. As Evelyn says, warn the owner that these may fall out eventually ( a bit like type 2/ replacement resorption in the cat). When the resorption is limited to the root, they don't seem to be painful. Once there is a defect palpable in the crown, (which you can detect during your oral examination with sharp explorer probe), they seem to be painful. I usually treat these by removing as much of the root substance as possible- when attempting extraction, it will break at the part which is bone, so you end up effectively doing a low-crown amputation. Then suturing gingiva over extraction site, so no bone exposed. If entirely confined to roots, monitor, and review radiographically in 6 months.

How old is the dog? I'm guessing middle-aged, from the wear on the crowns.

One sees resorptions sporadically, I think is the word. I'm sure there are myriad causes and i've no idea what it is in this case. If it is really all the premolars, one might speculate about some incident or illness transiently interfering with blood supply, for instance. Perhaps some of the diplomates lurking have more knowledge.

As for treatment, if they are not mobile and not uncomfortable, i don't think I'd do anything. Warn owner the crowns may drop off?

This is the crown of the same tooth.
