Thank you so much for your reply and advise - the fractured deciduous tooth hadn’t been extracted and according to the owner had ‘fallen out’ naturally when the permanent tooth erupted. Thanks again for your help - much appreciated!

Well, it surely wasn't this one

J.G. Turner, 1870-1955, held senior positions at Royal Dental Hospital, London, between the wars.

Wot Rob says about sealing. I might use a flowable composite, aware that this ismildly controversial. Monitoring is desirable, though you might find it hard to get the owner to accept frequent radiography.

Fairly often, even with no treatment at all, such teeth have no trouble. I don't mean you can disregard them, but the pulp does have its own defences. Certainly such teeth are just as strong as any other tooth.

It looks to me on the photo as if the enamel defect on the 404 extends below the gumline. You might need to take measures for oral hygiene at this spot.

Was the fractured deciduous tooth extracted?

This tooth has enamel hypoplasia resulting from interruption of amelogenesis during tooth development. This could be from the same trauma which fractured the deciduous tooth, from periapical infection around the apex of the fractured deciduous tooth if left in situ, or from damage caused during extraction of the deciduous tooth. These are sometimes know as "Turner's teeth" - I can't remember who Turner was but I'm sure Evelyn will know....

The lack of decent enamel will make the tooth more vulnerable to ingress of bacteria into exposed dentine tubules. Ideally it should be radiographed and if all appears ok the affected areas of exposed dentine should be sealed with an unfilled resin. It should then be monitored radiographically as the dog matures.
