Can spacing between the two teeth can cause loss of embrasures or interdental papilla? or is that only possible due to periodontal problems?

Depends: If the spacing is recent, it would indicate changes in the bone support or occlusion. Best to schedule a dental visit for xrays and probing to determine cause.

Spacing: Im to loss of bone and properly positioned teeth can contribute to loss of both bone and the soft tissues that cover the bone. If you fave improperly positioned teeth, please see a specialist Ortodotist. The service of a gum specialists. Periodontist, is also recommended.

Yes, Normal: Patients with healthy gums and large spaces between teeth usually have small, low papillae or no papilla at all, because the distance between the teeth is large, the bone is flattened and the papilla does not exist, As long as the gums are healthy and the teeth are not decayed then this condition is normal. If you want to remedy this, you need to move the teeth close to each other’s with braces.
