Hemisection Tooth: Saving a Tooth When One Root Is Removed

A tooth problem does not always affect every part of a multi-rooted tooth. In selected situations, a dentist may discuss a hemisection tooth procedure, where one root and the corresponding portion of the crown are removed while the remaining part is retained.

If you have been told that one root of a molar needs to be removed, it is natural to wonder whether the entire tooth must come out. This guide explains what tooth hemisection means, how it differs from root amputation and root canal treatment, what the procedure involves, and what happens to the remaining tooth.

What Is a Hemisection Tooth Procedure?

A tooth hemisection is a procedure generally associated with multi-rooted teeth, particularly molars. The tooth is divided so that one root and its associated part of the crown can be removed, while the remaining portion is retained.

The exact approach depends on the tooth’s anatomy and the amount and condition of the remaining structure. The dentist also considers how the retained portion can be restored and maintained.

Hemisection vs Root Amputation

These terms can sound similar, but they do not always describe the same procedure.

• Hemisection: Generally involves removing one root along with the corresponding part of the crown.
• Root amputation or root resection: Generally refers to removing a selected root while retaining the crown portion.
• Dental terminology can vary, so your dentist can explain exactly which part of the tooth is planned for removal.

Hemisection vs Root Canal Treatment

A root canal treatment focuses on the internal canals of a tooth. Hemisection involves removing a selected portion of a multi-rooted tooth.

In some cases, root canal treatment may form part of the overall treatment plan, but the two procedures have different purposes.

Why Might a Dentist Consider Hemisection?

The key question is whether the remaining part of the tooth can be retained and appropriately restored.

A dentist may discuss hemisection when the problem is mainly associated with one root or one section of a multi-rooted tooth. The assessment may include:

• The condition of the affected root
• The condition of the remaining root or roots
• The amount of tooth structure that can be retained
• The condition of the crown
• The position of the tooth and its role in the bite
• Whether the remaining portion can be restored and maintained

This is why hemisection is not determined by symptoms alone. A dental examination and appropriate imaging help the dentist understand the tooth before recommending a treatment approach.

How Is a Hemisection Performed?

The exact steps vary from case to case, but the process can generally be understood in stages.

1. Examination and Planning

The dentist examines the tooth and reviews its root structure. Dental imaging may be used to assess the roots and surrounding area.

2. Preparing the Tooth

The treatment area is prepared. Local anaesthesia may be used as part of the procedure.

3. Separating the Tooth

The multi-rooted tooth is carefully divided so the selected portion can be separated from the part intended to remain.

4. Removing the Selected Portion

The affected root and corresponding tooth segment are removed according to the treatment plan.

5. Restoring the Retained Portion

The remaining tooth structure may require a suitable restoration. The choice depends on the amount of tooth structure remaining and the dentist’s assessment.

6. Follow-Up

Follow-up appointments allow the dental team to review the treated area and the restoration.

What Happens to the Remaining Part of the Tooth?

The retained portion is an important part of the treatment plan. Hemisection is not simply about removing a root; it also involves deciding how the remaining tooth structure will be restored and used.

The type of restoration depends on factors such as the amount of remaining tooth structure, the tooth’s position and the planned function. There is no single restoration that applies to every hemisection case.

Hemisection vs Complete Tooth Extraction

With a complete extraction, the entire tooth is removed. With hemisection, a selected portion of a multi-rooted tooth is removed and the remaining portion is retained.

The choice between these approaches depends on the condition and structure of the individual tooth. If hemisection is not appropriate, the dentist can discuss other treatment options.

What Should You Expect After Hemisection?

After the procedure, your dentist will provide instructions based on the treatment performed and the restoration planned.

General points to discuss with your dental team include:

• How to keep the treated area clean
• When normal chewing can be resumed
• What restoration is planned for the retained portion
• When a follow-up appointment is required
• Which symptoms should be reported to the dental team

Following the specific instructions provided for your case is important because the treatment and restoration can differ from one tooth to another.

Is Hemisection Suitable for Every Tooth?

No. Hemisection is considered only after examining the tooth and its remaining structure.

The dentist may assess:

• Root shape and separation
• Remaining tooth structure
• Condition of the retained portion
• Access for treatment and cleaning
• Bite and tooth position
• Restoration requirements

This assessment helps determine whether retaining part of the tooth is a reasonable option or whether another approach should be considered.

Questions to Ask Your Dentist About Hemisection

If you have been told that one root or one section of a molar is affected, consider asking:

• Is the problem limited to one root?
• Can the remaining part of the tooth be retained?
• Is hemisection or root amputation being considered?
• What restoration will the remaining tooth need?
• What are the alternatives?
• What follow-up will be required?

Understanding the reason behind the recommended procedure can make it easier to compare your options and make an informed decision.

Final Takeaway

A hemisection tooth procedure is a treatment approach in which a selected portion of a multi-rooted tooth is removed while the remaining portion is retained. The procedure is planned around the tooth’s anatomy, remaining structure and restoration needs.

If your dentist has mentioned removing only one root, ask whether the procedure being discussed is hemisection, root amputation or another form of treatment. A clear explanation of the tooth’s condition can help you understand why a particular option has been recommended.

Frequently Asked Questions About Hemisection Tooth

What is a hemisection tooth?

A hemisection tooth procedure involves dividing a multi-rooted tooth and removing one root with its associated part of the crown, while retaining the remaining portion when it can be appropriately treated and restored.

Is hemisection the same as removing one root?

Not exactly. Hemisection generally involves removing one root along with the corresponding part of the crown. Root amputation or root resection may refer specifically to removing a root while retaining the crown.

Can a molar undergo hemisection?

Hemisection is associated with multi-rooted teeth, particularly molars. Whether a particular molar is suitable depends on its anatomy, remaining structure and overall dental condition.

Is hemisection the same as a root canal?

No. Root canal treatment addresses the internal canals of a tooth, while hemisection involves removing a selected portion of a multi-rooted tooth. The two procedures can sometimes be part of the same treatment plan.

What happens after a tooth hemisection?

After hemisection, the remaining tooth portion may require restorative treatment. Follow-up is used to review the treated area and the restoration according to the dentist’s plan.

How do I know if hemisection is suitable for my tooth?

A dentist needs to assess the tooth’s roots, remaining structure, surrounding area, bite and restoration requirements. Symptoms alone cannot determine whether hemisection is appropriate.

What are the alternatives to hemisection?

Depending on the condition of the tooth, a dentist may discuss other options, including different forms of root treatment, restoration or complete tooth removal followed by a suitable replacement option. The choice depends on the individual case.
