Home / Case Studies / Tooth Restorations / Crowning a cracked upper molar
The patient presented without pain or symptoms, unaware that anything was wrong. During routine examination, however, we identified visible fracture lines running across an upper molar. This finding was particularly important given the patient’s history of fractures in other teeth—some of which had progressed to the point of requiring extraction, including the tooth directly behind this one. As the last remaining tooth in the arch, preserving its strength and function was essential.

Although the tooth was still vital and symptom-free, fracture lines indicate areas of weakened tooth structure that can worsen under normal chewing forces. Considering the patient’s history and the strategic importance of this tooth, we discussed preventive treatment options.
To significantly reduce the risk of the tooth splitting, we recommended placing a crown. A crown encases the tooth and helps distribute biting forces evenly, offering much stronger protection than a filling alone.
We proceeded with a lab-made zirconia crown—our preferred choice for back teeth due to its high strength and reliable fit. As with all our crowns, it was crafted locally by Toothworx, ensuring excellent quality and a natural appearance.
The final crown was fitted comfortably and now provides durable reinforcement for the last tooth in the arch. The patient can chew confidently, knowing the risk of future fracture has been greatly reduced. Note: the excess cement on the tooth in front was removed following seeing it the the photo 🙂

As a family-owned and operated practice, we occasionally take time away for holidays and family commitments. During these times, our phones and emails may not be monitored, and we understand how stressful a dental emergency can be.
If you have an urgent dental issue outside our normal hours or while we’re away, you can find an emergency or after-hours dentist through the Australian Dental Association (SA Branch) website:
www.sa.ada.org.au/after-hours-and-emergency-dentists
They maintain an up-to-date list of practices across South Australia that can assist with urgent care when your regular dentist is unavailable.
We look forward to helping you again once we’re back in the clinic and hope you’re comfortable until then.
Thankyou everyone for your support this year and we wish you all a Merry Christmas and happy new year!
We we be taking a break for for a family holiday starting December 23, 2024, to January 2, 2025.
If you have a dental emergency over the break North Adelaide Dental Care will be open and can be contacted on (08) 8267 1894
