Not every tooth comes out in one piece. Multi-rooted teeth, impacted wisdom teeth, and teeth with curved or divergent roots often need to be divided before they can be safely removed. This is where tooth sectioning instruments come in — specialized tools designed to split teeth into smaller, manageable segments during extraction.
This guide explains which instruments are used to split teeth, how they work, and why proper technique and instrument selection matter in surgical extraction.
Why Teeth Need to Be Split During Extraction
A simple extraction works well for single-rooted teeth with straightforward anatomy. But multi-rooted teeth, impacted teeth, and teeth with curved roots often resist removal in one piece. Attempting to extract such a tooth whole can result in root fracture, excessive bone removal, or damage to the surrounding alveolar bone.
Tooth sectioning — also called root sectioning or crown sectioning — divides the tooth at the roots or crown, allowing each segment to be removed individually with controlled extraction technique. This approach minimizes trauma, supports bone preservation, and improves outcomes for procedures like immediate implant placement and socket preservation.
The Instrument Designed to Split Teeth: Dental Chisels
The primary instrument designed to split teeth is the dental chisel. Dental chisels are wedge-shaped surgical instruments used together with a surgical mallet to apply controlled force, splitting the tooth along its natural anatomical planes.
There are different chisel designs suited to different applications:
Straight Chisel — Used for general tooth sectioning where direct, linear force is needed to split the crown or root.
Bibevel Chisel — Featuring bevels on both sides, this chisel allows controlled cutting in tighter or more angled surgical fields.
While chisels remain a traditional and effective method, many modern oral surgery practices now favor rotary instruments for greater control and predictability.
Rotary Instruments Used for Tooth Sectioning
Tungsten carbide burs and fissure burs, used with a surgical handpiece, are widely used today for root sectioning and crown sectioning. These rotary instruments allow the surgeon to make precise cuts through enamel, dentin, and root structure without relying on the mechanical impact force used in chisel techniques.
Round burs are often used to create access points or remove bone around impacted teeth, while fissure burs are better suited to the actual sectioning cuts due to their cutting edge geometry.
Elevators Used Alongside Sectioning Instruments
Once a tooth has been sectioned, dental elevators are used to gently luxate and lift each segment from the socket. Several elevator types are commonly used in extraction procedures:
Cryer Elevator — Designed for removing root tips and sectioned root fragments with precision.
Winter Elevator — Effective for elevating impacted teeth, particularly lower molars.
Warwick James Elevator — A versatile elevator used for both straightforward and surgical extractions.
Coupland Elevator — Commonly used to widen the periodontal ligament space before extraction.
Bein Elevator — Designed for fine root elevation with minimal force.
Periotomes, a finer variation of the luxating elevator, are also used to sever the periodontal ligament gently, supporting atraumatic extraction and better bone preservation.
Forceps Used in the Final Stage of Extraction
After sectioning and elevation, dental forceps — including extraction forceps and root forceps — are used to grasp and remove the loosened tooth segments. Choosing the correct forceps design, matched to the tooth’s anatomical position, helps avoid unnecessary pressure on adjacent bone and tissue.
Why Instrument Quality Matters in Surgical Extraction
Tooth sectioning is a precise, controlled process, and the quality of the instruments used directly affects the outcome. Chisels, burs, elevators, and forceps made from medical-grade stainless steel or surgical-grade stainless steel hold their cutting edges longer, resist corrosion, and withstand repeated sterilization without degrading.
Precision-engineered instruments with CE compliance and ISO-certified manufacture give surgical teams the confidence that every tool performs consistently, procedure after procedure. For practices and clinics sourcing instruments at scale, working with a dental instrument manufacturer or supplier that offers OEM dental instruments or private label dental instruments ensures both quality and consistency across the surgical kit.
Final Thoughts
The instrument designed to split teeth is most directly the dental chisel, though modern oral surgery increasingly relies on rotary instruments such as tungsten carbide and fissure burs for greater precision. Paired with the right elevators and forceps, these tools form a complete system for safe, controlled tooth sectioning and extraction.
Understanding how each instrument functions — and investing in quality, reusable, autoclavable instruments — supports better surgical outcomes and long-term reliability in any oral surgery practice.
