Elephants are either left- or right-tusked, and the dominant tusk is generally smaller because of wear and tear from frequent use.

I think if I were applying for a job as a mahout, I would have failed the entry application


With that, may I ask, are the rest of the elephants teeth also of ivory? or are teeth and tusks made of different biological material?

I think there is differences in the 'tusk' teeth due to their continuing growth process, which is not seen in 'permanent' teeth. I'm guessing the root end of the 'tooth' would have the dentine, nerves, pulp and enamel like or own teeth.

Aha!, I was correct:
===============================================
The visible, ivory part of the elephant's tusk is made of dentine with an outer layer of enamel. Elephant ivory is unique which when viewed in cross-sections reveals criss-cross lines that form a series of diamond shapes (Schreger lines- see below). Elephants tusks never stop growing so some old bulls display enormous examples.
===============================================

One mammal that only grows only one toothy canine tusk is the Narwhal. It's ivory rapier can grow up to 9 feet (2.74 metres) long. It's spiralling tusk was frequently sold as a unicorn's horn in ancient times, thought to have magical powers. Didn't help the poor narwhal it came from in the end tho. They use them as clubs rather than spears, striking fish to stun them before eating them. They apparently are somewhat porous and the dentine has nerve endings which enable them to detect among other things, water salinity, Female pheromones, etc. males have a ritual get together where they clash their tusks together en-mass, but do not fight with them. Guess they are comparing the length of their toothy member rather like we compare other bits of our more visible anatomy (heir's is hidden in a sheath to cut down on water resistance ).

I think it must be relatively save to say, that the tusk swords and the trunk swords were not used at the same time, or the elephant may have cut the trunk while wildly fighting.
Trunk swords would have been effective against foot soldiers, just like when the elephants had a chain in the trunk, but would tusk swords not have been more effective against riders/horses?

Nordelunde; Elly armour appears to at least partially cover the trunk, but leaves the working more flexible and controllable end free. Should protect him from self harm as well as from the enemy.

Migrating the old saying: he (an elephant) may be an animal but he is not stupid. I would reject the idea that such inteligent and skilled animal would inadvertly cause self damage. It is all about protecting him from enemy's atempts to take him down.

Yes I know the elephant armours, but the underside of the trunk was not protected.
Someone I knew in Denmark, had once bought an elephant armour in India - years ago, but it was confiscated by the Indians.

The armour in the picture doesn't have to be the real whole thing; more a parade version ?

here we see an elly using it's dominant tusk to eat a tree! - Note the end is broken...

https://www.youtube.com/watch?v=TJ0R01X6t5E

they seem to have no qualms about using their tusks fro digging, shredding trees, moving stuff, or using them as weapons. (more info on tusk interiors in this one too)

We now are all elephant experts!

Still they can have a determined degree of sensivity ... and eventually crack. Only that they know how to use them ... angle and all. As you showed, a significant part of their length is hollow ... and that counts.

Unlike humans, elephants change their teeth 6 times during their lives. Their teeth don’t grow upwards, like in humans, but horizontally. They start with the size of thumb nail.
When they grow old and find it difficult to chew hard food, they move to places with softer vegetation, such as swamps. Eventually they will die because of their weakness and will die near the water. This frequent ending is what originates the myths of elephant graveyards.
The fangs (tusks) of elephants are the incisors in the other mammals and appear as from the age of one year. The particularity of these is that they lack tooth enamel. When the fang pops out, it still has a small layer of enamel that will disappear with use, leaving a fang made basically of dentin.
Approximately 2/3 of the fang are visible and alive, this meaning that it has an inner cavity with pulp including blood vessels and nerves. This is why fangs are so sensitive to blows and force*. The last third of the fang is located in the lower part of the skulls.
When a fang breaks, it can cause serious complications to the elephant. In extreme cases the nerve, the pulp, is exposed and the animal dies due to suffering great pain.
* Something which doesn't concur with the idea of 'operational' tusk swords ...
