Not every tooth comes out in one piece, and that’s not a sign of anything going wrong. Splitting a tooth into sections before removal is a deliberate, planned part of some extractions, particularly where the tooth’s shape or position makes a single removal impractical.
It’s a Deliberate Technique, Not a Complication
A sectioned tooth extraction involves your dentist or oral surgeon cutting a tooth into two or more pieces before removing each section separately, rather than attempting to take the whole tooth out at once. This approach is generally planned in advance based on the tooth’s roots, position, and the space available, not decided on the spot because something has gone wrong.
- Sectioning is common for teeth with curved, multiple, or awkwardly positioned roots
- It’s a standard technique, particularly for impacted or partially erupted wisdom teeth
- The tooth is numbed the same way as any other extraction before sectioning begins
- Removing smaller sections can actually reduce trauma to the surrounding bone and gum
Why Some Teeth Can’t Come Out in One Piece
Teeth aren’t uniform in shape below the gumline. Roots can curve, split, or angle in directions that make pulling a whole tooth straight out difficult without putting unnecessary pressure on the surrounding jawbone. Healthdirect explains that the procedure for removing a wisdom tooth may involve taking away some bone around the tooth, and that the tooth may be cut into smaller pieces as part of the process, particularly for lower wisdom teeth, which tend to be more difficult to remove than upper ones.
Sectioning addresses this by breaking the tooth down into pieces that are each easier to manoeuvre out through the available space, rather than forcing an oddly shaped or firmly rooted whole tooth through a gap that isn’t quite big enough for it.
When Sectioning Is More Likely to Be Needed
A few situations tend to make sectioning a more likely part of the plan.
Impacted or Partially Erupted Teeth
Wisdom teeth that haven’t fully come through, or that are angled against neighbouring teeth, often don’t have a clear path for removal as a single unit. Splitting the tooth allows each section to be removed along a more manageable trajectory.
Curved or Multiple Roots
Some teeth, particularly molars, naturally have two or three roots that can curve in different directions. Removing the crown and roots separately, or splitting the roots from each other, can make the procedure more predictable than attempting to pull a multi-rooted tooth out whole.
Limited Space or Access
Where a tooth sits close to a nerve, another tooth, or a limited amount of bone, your surgeon may plan to section the tooth specifically to reduce how much force or movement is needed during removal.
What the Process Actually Involves
Sectioning happens after the area has been numbed, using the same local anaesthetic approach as a standard extraction.
- The gum may be opened slightly to give access to the tooth and surrounding bone
- The tooth is carefully cut into sections using a small handpiece
- Each section is then removed individually
- The socket is cleaned and checked once all pieces have been taken out
This is a controlled, precise process rather than something improvised mid-procedure, and your dentist or oral surgeon will generally have identified the likely need for sectioning during your assessment and x-rays, before the appointment even begins.
Does Sectioning Change Recovery?
Not significantly. Because the aim of sectioning is often to reduce trauma to the surrounding bone compared to forcing a whole tooth out, recovery generally follows a similar pattern to any other surgical extraction. Some swelling and discomfort in the days afterward is normal, and your dentist will provide specific aftercare guidance based on your particular procedure. If you’re looking for general guidance on managing discomfort after a wisdom tooth removal, our post on dealing with wisdom tooth pain covers some of what to expect.
Signs a Wisdom Tooth May Need This Approach
Certain symptoms sometimes point toward a wisdom tooth that’s likely to be more complex to remove, which is worth mentioning if you’re booking an assessment.
- Ongoing swelling or infection around a partially erupted tooth
- Pain that flares up repeatedly around the back of the jaw
- Difficulty keeping the area clean due to the tooth’s position
Our post on infected wisdom teeth goes into more detail on when these symptoms warrant a proper assessment rather than waiting them out.
Getting an Accurate Picture Before Treatment
X-rays play a significant role in planning any extraction, and this is especially true when sectioning is likely to be part of the approach. Seeing the shape, position and angle of the roots in advance allows your dentist or oral surgeon at Wahroonga Dental Group to plan the procedure properly, rather than encountering unexpected root anatomy partway through.
Frequently Asked Questions
Is a Sectioned Extraction More Painful Than a Regular One?
Not inherently. Local anaesthetic is used throughout, regardless of whether the tooth is removed whole or in sections. Any difference in discomfort afterward is more closely tied to how involved the overall procedure was, rather than sectioning itself. Individual experiences vary.
Does Sectioning Mean My Extraction Is More Complicated?
It generally reflects the tooth’s anatomy rather than a complication with your specific case. Many straightforward, well-planned extractions involve sectioning simply because of how the roots are shaped or positioned. Your dentist can explain the specific reasoning for your tooth.
Will I Need Stitches if My Tooth Is Sectioned?
Possibly, particularly if the gum needed to be opened to access the tooth. Whether stitches are used depends on the specific procedure, and your dentist will explain what to expect for your situation.
How Long Does a Sectioned Extraction Take Compared to a Standard One?
It can take a little longer than a straightforward extraction, since each section is removed individually rather than the whole tooth at once. Timeframes vary depending on the tooth and its position, and your dentist can give you a general idea based on your assessment.
Can I Ask in Advance if My Tooth Will Need Sectioning?
Yes, this is a reasonable question to raise during your consultation. Your dentist or oral surgeon can generally give you an indication based on your x-rays, though the final approach is sometimes confirmed once the procedure is underway. If you’ve had prolonged discomfort after a previous extraction, our recovery guide on managing pain after an extraction may also be worth a read beforehand.
Considering an Extraction Assessment?
If you’ve been told a tooth might need to come out, particularly a wisdom tooth, having it properly assessed with x-rays beforehand gives your dentist the clearest picture of what the procedure will involve. You can book an appointment online to get started.
