Can I Still Use Autogenous Wisdom Tooth Transplant After 6 Years? - Dentistry

Share to:

The upper left first molar was extracted about 6 years ago. Is it still possible to use an autogenous tooth transplant?


Hello, doctor.
About six years ago, my upper left first molar was extracted because it cracked due to biting on something hard.
At that time, the dentists mostly said that the only options were dental implants or bridges, so I was unaware of the option for autogenous tooth transplantation using wisdom teeth.
Most of my wisdom teeth are still impacted and have not erupted, so I haven't had them extracted yet.
The gap from the missing tooth has not been filled, and overall, my teeth have not shown any significant changes or movement; only the lower left horizontally positioned wisdom tooth has partially erupted.
I would like to ask, after all this time, is it still possible to use autogenous wisdom tooth transplantation?

Hello: It is recommended to have a detailed discussion with an oral surgeon, as it is necessary to consider not only the complete extraction of the lower left wisdom tooth but also the successful completion of root canal treatment for that tooth.
Additionally, the size, shape, and occlusion of the tooth must closely match the edentulous area for successful implantation.
Therefore, a comprehensive evaluation is required to determine the feasibility.
Sincerely, Lin Chia-Yung, Department of Dentistry, Taichung Hospital, Ministry of Health and Welfare.

Autogenous wisdom tooth transplantation, also known as autotransplantation, is a dental procedure where a tooth (in this case, a wisdom tooth) is moved from one location in the mouth to another, typically to replace a missing tooth. In your situation, where the upper left first molar was extracted six years ago, and the wisdom teeth are still impacted, there are several factors to consider regarding the feasibility of this procedure.

Firstly, the primary concern is the condition of the wisdom tooth that you are considering for transplantation. The wisdom tooth must be fully developed and in good health to be a viable candidate for transplantation. If the wisdom tooth is still impacted and has not erupted, it may be challenging to assess its condition without a thorough examination by a dental professional. The tooth must be carefully extracted to avoid damage to its roots, and it should be suitable for root canal treatment if necessary, as this is often required after transplantation to ensure the tooth remains viable.

Secondly, the size and shape of the wisdom tooth must be compatible with the space left by the extracted molar. If the wisdom tooth is significantly smaller or larger, it may not function properly in the new location. Additionally, the alignment and occlusion (bite) must be considered to ensure that the transplanted tooth can effectively participate in chewing and does not cause misalignment of the surrounding teeth.

Another important aspect is the healing process. After the transplantation, the site will require time to heal, and the transplanted tooth will need to integrate into the surrounding bone and gum tissue. This process can take several months, and regular follow-ups with your dentist or oral surgeon will be necessary to monitor healing and ensure that the tooth is settling properly.

In terms of timing, while six years have passed since the extraction, it is not necessarily too late for autogenous transplantation. However, the longer the time since the tooth was lost, the more complex the situation may become, as adjacent teeth may shift or the bone may change in density and shape. Therefore, a comprehensive evaluation by an oral surgeon or a dentist specializing in transplantation is crucial. They will likely conduct imaging studies, such as X-rays or a 3D cone beam CT scan, to assess the condition of the wisdom tooth and the surrounding structures.

Regarding costs, autogenous tooth transplantation can vary widely depending on the complexity of the case, the location of the dental practice, and whether additional procedures (like root canal treatment) are required. It is advisable to discuss the financial aspects with your dental provider upfront to avoid any surprises.

In conclusion, while it is possible to consider autogenous wisdom tooth transplantation even after six years, it requires careful evaluation and planning. Consulting with an experienced oral surgeon or dentist will provide you with the best options tailored to your specific situation. They will help you understand the potential risks and benefits, as well as guide you through the necessary steps to achieve the best possible outcome for your dental health.
