Study Notes

Indications for Dental Crowns

Dental crowns are needed when old restorative material is removed and replaced with core material and a crown.
Concerns arise when teeth start to break, potentially requiring crown lengthening surgery or resulting in non-restorable fractures.
Patients often experience emergencies when a cusp of a tooth breaks, usually caused by underlying cracks and sticky foods, not hard items.
Chewing ice can also lead to tooth damage by causing microscopic cracks due to temperature changes.
Another indication for a crown is a tooth with a fractured cusp, where the decision is made between leaving it as is or providing cuspal protection to prevent further damage.
Long-term studies show that the ten-year survival rate for teeth is higher with crowns than with leaving some sort of a buildup.
Severely carious teeth with a large amount of decay will likely require a crown due to compromised remaining tooth structure.
It is important to inform the patient early on about the need for a crown when extensive decay is present.
Patients should be advised against chewing ice due to its potential to cause tooth damage.
Dentists need to assess the situation, including occlusion, to determine if a crown is indicated.
The decision to place a crown is influenced by factors such as the extent of decay, the remaining tooth structure, and the need for root canal treatment.
The dentist's role is to inform the patient of the need for a crown and to make the appropriate recommendation.
