Generally speaking a chipped tooth must be treated immediately to prevent further fracture, tooth sensitivity or possible root canal treatment.
Chipped tooth does not cause decay, but if remained untreated for a long time, it can cause decay depending on how much dentin was exposed.
See your dentist or a dentist nearby to restore your tooth immediately.
