At London Dental Specialists, we understand that post removal for retreatment access can seem daunting. This procedure becomes necessary when a previous root canal treatment fails or when a post fractures inside your tooth. Our specialists use precise techniques to carefully remove dental posts under local anaesthesia, creating access for thorough retreatment. The process involves breaking down the cement holding the post, removing old filling materials, and properly cleaning the canals before refilling them. We prioritise your comfort throughout this procedure, ensuring minimal discomfort while restoring your tooth's health and function. Many patients have questions about what to expect before, during and after this specialised treatment.
What is post removal for retreatment access?
Post removal for retreatment access is a dental procedure where a metal post that was previously placed in a tooth's root canal is carefully removed. This is typically necessary when a tooth requires endodontic retreatment due to persistent infection or when the post has fractured. At London Dental Specialists, our endodontists use specialised equipment and techniques to safely remove posts while preserving the surrounding tooth structure.
Why would I need a post removed from my tooth?
You might need a post removed from your tooth for several reasons:
- The tooth has developed a new infection despite previous root canal treatment
- The post has fractured or become loose
- The tooth requires endodontic retreatment to address persistent symptoms
- There is decay beneath the crown that needs to be addressed
- The restoration needs to be replaced due to wear or damage
Is post removal a painful procedure?
Post removal at London Dental Specialists is performed under local anaesthesia, ensuring you remain comfortable throughout the procedure. You may feel some pressure during the treatment, but the anaesthetic prevents pain. Our specialists use precise techniques to minimise any discomfort. After the procedure, mild soreness for 1-2 days is normal and can typically be managed with over-the-counter pain relievers if needed.
How is a post removed during retreatment?
At London Dental Specialists, we remove posts using a careful, systematic approach:
- Administration of local anaesthesia to ensure comfort
- Removal of the crown or filling to access the post
- Use of specialised ultrasonic instruments to break up the cement around the post
- Gentle loosening and removal of the post using precise instruments
- Thorough cleaning of the canal to prepare for retreatment
Our specialists use magnification and advanced equipment to perform this procedure with minimal risk to the surrounding tooth structure.
What are the risks of post removal?
While post removal is generally safe when performed by specialists, there are some potential risks:
- Root fracture (rare but possible)
- Perforation of the root
- Inability to completely remove the post
- Temporary tooth sensitivity
At London Dental Specialists, our endodontists have extensive experience in post removal, significantly reducing these risks through careful technique and advanced technology.
How long does post removal take?
Post removal typically takes between 60-90 minutes at London Dental Specialists, depending on the complexity of your case. Factors that affect the duration include the type of post, how long it has been in place, and the condition of the surrounding tooth structure. Our specialists will provide you with a more accurate time estimate during your consultation based on your specific situation.
What should I expect after post removal and retreatment?
After post removal and retreatment at London Dental Specialists, you can expect:
- Mild discomfort for 1-2 days that can be managed with over-the-counter pain relievers
- You can brush and floss as usual, but be gentle around the treated area
- Avoid chewing on hard foods with the treated tooth until your dentist advises it's safe
- Avoid hot or cold beverages for the first hour after treatment
- A follow-up appointment to monitor healing and possibly place a new restoration
How successful is endodontic retreatment after post removal?
Endodontic retreatment following post removal has a success rate of approximately 70-80% when performed by specialists. At London Dental Specialists, our endodontists have extensive training and use advanced techniques to maximise success rates. The outcome depends on several factors including the reason for retreatment, the condition of the tooth, and how well the canals can be accessed and cleaned after post removal. We thoroughly evaluate each case to provide realistic expectations for treatment outcomes.
Will I need a new post and crown after retreatment?
In most cases, yes, you will need a new post and crown after retreatment at London Dental Specialists. Once the retreatment is complete and the tooth has healed, we will assess the tooth's structural needs. If the tooth requires additional support, a new post will be placed, followed by a new crown to restore function and aesthetics. Our team works closely with restorative dentists to ensure optimal long-term results for your treated tooth.
