Periapical abscess from invisalign?

[JiPo]

A friend of mine was diagnosed with periapical abscess and now needs root canal at a young age.

Is this a common complication of invisalign? She never had any tooth sensitivity or toothache other than some pain when changing invisalign trays. Even the abscess doesnt cause any pain, it was just so swollen and was seen on xray, so I assume the nerve is dead. Just don’t know when the nerve died when she did not have any symptoms before.

Thank you in advance.

Trauma can result in necrosis. And orthodontic movement is trauma. It’s an unlikely cause but possible. Likelier causes are cracks, dens evaginatus, pit and fissure caries with large/ high pulp horns. But quick, abrupt orthodontic movement is a possibility.

Pulpal reactions to ortho treatment are minimal. There’re occasional reports of loss of tooth vitality during ortho treatment. Usually there’s a history of previous trauma to the tooth (large restoration, trauma, trauma due to bruxism, etc.), but a sequence of abrupt ortho movements can be the cause of loss of vitality. It’s hard to tell the cause without other information
