Will My Final Dental Crown Fall Off Like the Temporary One?
I am nervous about getting my permanent dental crown because the temporary one will not stay on. I got the crown in May, and it came off three times. Each time, my dentist bonded it back on. Should I ask my dentist to retake impressions of the tooth? – Thank you. Anvit from Silver Springs, MD
Thank you for your question. Your concerns are valid; we recommend waiting before you get a final crown.
Is It Normal for Temporary Crowns to Fall Off?
Although a temporary crown may fall off, it is unusual to fall off three times within two months. Your dentist may have taken wrong impressions of your tooth or over-prepared it so the crown will not stay on.
Over-preparing a tooth for a crown
If a dentist aggressively prepares your tooth, it will not leave enough tooth structure for securing your crown. Strong dental cement will not keep the crown on because it may be so much larger than the tooth beneath it that the crown is not secure.
Inaccurate tooth impressions
It is not unusual for a dentist to take incorrect tooth impressions. Sometimes fluid oozes around the impression and contaminates it. A dentist must examine the impression to look for mistakes and retake the impression as needed.
Can You Switch Dentists for a New Crown?
Your temporary crown is the model that the dental lab will use for your final crown. If your temporary crown does not fit well, neither will your final crown. At this point, you can ask your dentist for a refund and a copy of your dental records. Look for an experienced cosmetic dentist to examine your tooth and take accurate impressions for a crown that looks natural and fits precisely.

My Dentist Says that an Implant Denture Won’t Work for Me
I have lost all but three of my lower teeth and agree with my dentist that it’s time for a complete denture. I asked about an implant denture, but my dentist said that implants will be too risky for me because I have diabetes and my bone level is low. I read online that if your diabetes is under control, you can qualify for implants. Why would my dentist say that I do not qualify without any proof? Thank you. Gabe from Amityville, NY
Thank you for your question.
Dr. Goebel would need to review your medical history, examine your oral tissue, and take a 3-D CT scan to measure your bone volume to determine whether you are a candidate for an implant overdenture, or a fixed denture.
Do Diabetes and Bone Shrinkage Disqualify You from Dental Implants?
Diabetes and bone shrinkage do not automatically disqualify you from getting dental implants. People with diabetes heal slower, so it may take longer for your jawbone to integrate with your dental implants. If you need bone grafting, the procedure will precede dental implant placement. Your implant dentist or an oral surgeon will give you detailed instructions for oral hygiene and promoting healing after your procedures.
The Journal of Pharmacy and BioAllied Sciences published a 2021 article on a study of forty-six dental implant patients. Results show that patients with good glycemic control had similar implant survival rates at patients without diabetes. Patients with uncontrolled diabetes had a higher rate of implant failure.
Other factors that may impair healing and dental implant longevity include:
- Inconsistent oral health habits
- Tobacco use
- History of gum disease
Request a Consultation
If you would like to know whether you qualify for dental implants, request a consultation with a restoring dentist, an oral surgeon, or a periodontist. After reviewing your medical history, completing an exam, and taking digital x-rays, they will explain whether you are a candidate for implants and discuss your options for implant overdentures.
