Odd canine resorption? in a cat

On the radiographs it certainly looks like attrition not resorption. Apart from anything else, the lesions don't seem to be in contact with any soft tissue. Are the edges of the craters smooth, as I suspect, or are there sharp edges that give a slight catch with an explorer?

I don't see on the radiographs any sign of tertiary dentine, so, to be sure there is no sensitivity and pain, tubule sealing would be best.

Sealing the dentine tubules just, well...... seals the dentine tubules. So it prevents or at least reduces sensitivity, and it protects the pulp. It doesn't strengthen the tooth and it doesn't prevent further attrition. (And, if this were a resorption, which we don't think it is, it would do nothing at all )

People have used all sorts of things. We used to use a self-curing varnish and assumed that it worked. A light-cured unfilled resin would be very good (just for example, Luxatemp glaze and Bond) or a modern flowable composite such as Vertise.

Obviously the teeth have been weakened a bit by the substance loss, but I don't think they are at hugely greater risk of fracture when I look at the radiographs. Might change my mind after seeing photos.

Thankyou both. I’ll see if can get some photos and have a closer look at the apposition of the maxillary and mandibular teeth.

How do you seal the dentine tubules and is this something I can do in practice? Does this just prevent further tissue loss or would it actually strengthen the teeth or will they be at higher risk of fracture regardless?

Without photos I would say these either attrition facets from opposing teeth in malocclusion or abrasion for some habitual behaviour such as licking an area of dermatopathy or something like wool.
Best practice is identify and eliminate cause and seal open dentin tubules

Any photos? Could this be attrition from contact with upper 03s? If so then possibly extraction of 03s if still touching but may have worn themselves a path by now, in which case I would probably leave them alone. In theory you could apply a non-filled resin to seal the exposed dentine tubules, but if this is due to gradual attritional wear then that is almost certainly not necessary.

Permission to post xrays.

Medial aspect of both mandibular canines- doesn't look or feel like 'normal' tooth resorption. Is there anything I should advise or treatment- essentially I am concerned re potential for fractures, no indication (pain wise) to extract at this stage. Cat was in for a dental procedure to extract a resorptive lesion on 307.
