Dental Extraction Forceps: #150, #151, #88R, #88L, Cow Horn & Universal

Dental extraction forceps are hinged surgical instruments that grip and remove teeth from the alveolar bone by functioning as class-1 levers. The six most clinically essential types are Forceps #150 (maxillary anteriors and premolars), #151 (mandibular anteriors and premolars), #88R (upper right molars), #88L (upper left molars), Cow Horn (mandibular bifurcated molar roots), and Universal forceps (multi-quadrant and root-tip retrieval). Together, these six instruments cover the vast majority of routine extraction procedures in general dental practice.
Choosing the right extraction forceps is not simply a preference. It directly shapes procedural success, patient comfort, and the risk of complications like root fracture. Yet the numbering system confuses dental students and experienced clinicians alike. The numbers come from three competing historical systems (American, English, and German) layered over more than a century of dental instrument development.
Many clinicians feel uncertain when building their instrument tray for the first time. That uncertainty is normal. What closes the gap between uncertainty and confidence is understanding each forceps by its design anatomy, arch specificity, beak shape, clinical indication, and technique, rather than memorizing numbers in isolation.
This guide covers each of the six essential forceps in that exact order. By the end, you will know which instrument to reach for, why it works, and what to do when it does not.

What Are Dental Extraction Forceps and How Do They Work?

Dental extraction forceps are hinged, lever-action instruments that convert hand pressure into controlled force at the tooth's cervical and root surface. Three components (beaks, joint, and handle) define every design. The beak geometry is what makes each forceps number clinically distinct.
Dental extraction forceps function as class-1 levers. Every forceps consists of three components:

• Beaks (tips): The active working end, shaped to engage the tooth below the gingival margin without damaging adjacent soft tissue.

• Joint (hinge): Connects the handle to the beaks, controlling the axis and magnitude of movement.

• Handle: The passive grip component that provides leverage, control, and force transmission.
  The beak geometry is what differentiates one forceps number from another. Beak width, curvature, tip sharpness, and the angle between the handle and beak all change depending on whether the tooth is maxillary or mandibular, anterior or posterior, single-rooted or multi-rooted.
  Maxillary forceps have straight or gently curved handles, aligned with the upward arc of the upper jaw. Mandibular forceps have a sharp downward angle at the shank, sometimes close to 90 degrees, to accommodate the vertical extraction trajectory of lower teeth.
  Holding both types side by side makes the difference immediately obvious. Reaching for the wrong forceps for the arch you are working on does not just feel awkward. It actively misdirects force and can cause root fracture or alveolar crest damage. Arch orientation is the first checkpoint experienced clinicians run through before sitting the patient back.

Forceps #150: The Upper Universal Workhorse

Forceps #150 are designed for maxillary anteriors and premolars. The straight, symmetrical beaks engage the tooth apical to the cervical line, allowing buccal-palatal rocking and rotational delivery. Forceps #150 are the single most-used upper jaw forceps in general dentistry worldwide.
The #150 works for both the right and left upper quadrants, which makes it "universal" for the anterior and premolar region. A small variant, the #150S (small), is available for pediatric patients or adults with limited mouth opening. You can view our full extraction forceps range to compare patterns and sizes.
When the beaks are seated correctly, you will feel a subtle but perceptible resistance against the root surface, a signal that the instrument has passed apical to the cemento-enamel junction (CEJ) rather than resting on enamel. Many students apply the beaks too coronally during early extractions. The sign is a wobble during rocking, because the beaks feel unstable when they are gripping crown, not root. The correction is always the same: reseat deeper, not harder. Learning to read that tactile feedback early is one of the clearest signs of developing clinical judgment.
Clinical technique with Forceps #150:

1. Apply the beaks as far apical as possible, below the gingival margin.

2. Seat firmly without rocking or levering against adjacent teeth.

3. Apply slow buccal-palatal rocking movements to expand the socket and disrupt the periodontal ligament.

4. Add a gentle rotational component for single-rooted teeth. Incisors and canines tolerate rotation well.

5. Deliver the tooth in a buccal direction once mobility is achieved.
   When to choose #150 vs. other maxillary forceps: Forceps #150 suits intact crowns with predictable root anatomy. When the crown is severely compromised by decay or fracture, or when root dilaceration is visible on the radiograph, use a periosteal elevator before placing the forceps. This reduces the chance of crown fracture during seating, which is harder to manage mid-procedure than it sounds.

Forceps #151: The Lower Universal Counterpart

Forceps #151 are designed for mandibular anteriors and premolars. The angled handle accommodates the downward trajectory of mandibular access, and the symmetrical bird-beak design allows buccal-lingual rocking for all lower single-rooted teeth. Forceps #151 cover the same anterior and premolar range in the lower jaw that the #150 covers in the upper.
The functional difference between the #151 and #150 lies almost entirely in handle geometry. 

The #151 features a pronounced downward angle at the shank, typically approaching 90 degrees from the beak axis, which positions the operator's grip below the occlusal plane and enables true vertical force application for mandibular teeth. The beaks themselves are nearly identical to the #150: symmetrical, narrow, and designed to seat below the cervical line.
The #151 covers mandibular incisors, canines, and premolars (first and second). For most clinicians, it is the first instrument placed on the tray for any lower anterior or premolar case.
The temptation with the #151 is to brace against the mandible and pull upward rather than commit to true buccal-lingual rocking. That substitutes leverage for periodontal ligament disruption, and it is the pattern that most commonly produces root tip fractures in lower premolars. The correct motion is a deliberate, patient figure-eight: slow buccal, slow lingual, slow buccal, with each cycle slightly wider as the socket expands. If the tooth is not moving after four to six cycles at reasonable force, stop. Something in the root anatomy, such as a hook, hypercementosis, or adjacent bone density, is resisting. Switch to a luxator before returning to the forceps.
Clinical technique with Forceps #151:

1. Confirm adequate inferior alveolar nerve block. Mandibular posterior teeth have a higher anesthetic failure rate than upper teeth, and patient movement during seating eliminates control entirely.

2. Seat the beaks as far apical as possible, using firm downward pressure along the long axis of the tooth.

3. Begin a controlled buccal-lingual rocking sequence, slow and deliberate, not fast and forceful.

4. For mandibular canines, add a modest rotational component after initial mobility is confirmed.

5. Deliver the tooth in a buccal direction once socket expansion is established.
   When #151 is not the right choice: The #151 is not suited for mandibular molars. The moment the beaks slip or fail to seat apically, the tooth's anatomy is telling you to change instruments. Switching to the appropriate molar forceps at that point is the correct clinical decision. Persisting with the wrong instrument is where fractures happen. For teeth that resist forceps alone, keep a set of dental elevators within reach.

Forceps #88R: Upper Right Molar Extraction Forceps

Forceps #88R are designed for the maxillary right first and second molars. The asymmetric beak design, a pointed palatal beak and a wider bifurcated buccal beak, adapts to the three-rooted anatomy of upper molars. The "R" designation means the palatal beak orients toward the patient's right palatal root when held in the standard grip.
Upper molars present a specific challenge that no symmetrical instrument can solve: three roots, two buccal (mesiobuccal and distobuccal) and one large palatal, splayed at different angles within the alveolus. The #88R addresses this with asymmetric beak tips. The palatal beak is narrow and pointed, designed to engage the conical palatal root. The buccal beak is wider and bifurcated to straddle the two buccal roots simultaneously.
Many students pick up the #88R for an upper left molar and attempt to seat it. The result is immediate: the beak geometry faces the wrong direction, and neither tip engages correctly. The fix is straightforward but not intuitive. Hold the closed forceps to the tooth before placing it. If the pointed tip naturally faces the palatal root, the instrument is correct. If it faces the buccal space, you have the wrong side. The letter designation tells you which side of the mouth you are working, not which hand you hold the instrument with. One visual check before placement saves the entire procedure.
Clinical technique with Forceps #88R:

1. Review the periapical radiograph for root divergence, hypercementosis, or proximity to the sinus floor before picking up any instrument.

2. Seat the palatal beak first, driving it apically along the palatal root.

3. Engage the buccal beak against the buccal root surface, aiming to straddle the furcation.

4. Apply slow buccal-palatal rocking, with slightly greater force toward the buccal, since this is the direction of least resistance for most upper molars.

5. Add a gentle distal tipping component and deliver buccally.
   When #88R is not the right tool: Upper second molars with fused roots may not respond well to asymmetric beak geometry. If resistance persists after adequate elevation, switching to a bayonet-pattern universal forceps or sectioning the crown before forceps application is the safer approach. Forcing a seat on a fused-root molar with asymmetric forceps commonly results in buccal plate fracture. You can review the paired 88R and 88L upper molar forceps to keep the right instrument on hand.

Forceps #88L: Upper Left Molar Extraction Forceps

Forceps #88L are the mirror image of the #88R, designed specifically for the maxillary left first and second molars. The beak orientation is reversed to correctly engage the palatal and buccal root structure from the left side of the arch. Using #88R on the upper left, or #88L on the upper right, produces inadequate root engagement and elevated fracture risk.
Forceps #88L is anatomically identical to the #88R in every respect except one: the beak orientation is mirrored for the upper left quadrant. The palatal beak is pointed, the buccal beak is bifurcated, and the mechanics during rocking are the same, but only when the correctly oriented instrument is used.
Clinicians who perform bilateral molar extractions in the same appointment will alternate between #88R and #88L. Both instruments belong on the tray from the start. Reaching for the wrong one mid-procedure and attempting to compensate with force is one of the most common contributing factors in buccal plate fracture during upper molar extraction.
Upper molar anatomy requires the palatal beak to engage the palatal root independently, because that root is the longest and most conical root in the mouth. When the #88R is used on the upper left, the palatal beak angles away from the palatal root instead of into it. The result is a forceps that appears seated but has not actually engaged the most important root, and under rocking force, the unengaged palatal root fractures at or near the apex. Radiographic confirmation of complete root removal after every upper molar extraction is not optional. It is the standard of care. If a root tip breaks off, keep a root tip forceps set on hand for safe retrieval.
Clinical technique with Forceps #88L:

1. Visually confirm the "L" designation before seating. Hold the closed forceps to the tooth and verify that the pointed beak faces the palatal root on the left side.

2. Seat the palatal beak along the palatal root, driving apically.

3. Seat the buccal beak to engage the buccal furcation.

4. Apply the same buccal-palatal rocking sequence used with the #88R.

5. Deliver buccally after adequate mobility is achieved.
   When #88L requires supplemental elevation: Upper left first molars with widely divergent buccal roots may not allow the #88L to fully seat without prior elevation. This is especially true in patients with dense cortical bone or a history of parafunctional habits. Use the forceps beaks to confirm access, not to force a pathway. If the beaks cannot seat below the CEJ without excessive effort, stop and luxate first with a luxator.

Cow Horn Forceps: The Furcation Specialist

Cow Horn forceps (also called #23 forceps) have two sharply pointed, inward-curved beaks designed to engage the furcation of mandibular molars rather than the crown surface. The instrument works through a pump handle elevation technique, driving the beaks into the bifurcation to hydraulically displace the tooth coronally. Cow Horn forceps are indicated for lower first and second molars with intact, well-defined furcation anatomy.
Cow Horn forceps earn their name accurately: when open, the two pointed beaks look like the horns of a bull. The design is not incidental. It is mechanically deliberate. The beaks bypass the crown entirely and engage the interradicular bone at the furcation, which changes the physics of the extraction. Instead of gripping the crown and transmitting force coronally, the Cow Horn transmits force at the root level, directly where the tooth must separate from bone.

The result is a more efficient elevation with lower risk of crown fracture, which is particularly valuable in mandibular molars with large restorations, endodontic access preparations, or any structural compromise that makes crown engagement unreliable.
The Cow Horn does not rock in the traditional sense. The motion is a controlled axial pump. Apical pressure is applied and slowly increased as the beaks seat progressively deeper into the furcation. Clinicians using this instrument for the first time frequently note that the tooth appears to rise toward them rather than needing to be pulled. That sensation is correct and expected. The beaks are displacing the tooth coronally as they advance apically into the bifurcation. Resisting the instinct to pull and instead trusting the pump motion is the technical adjustment most students need to make, usually within one or two procedures.
Clinical technique with Cow Horn forceps:

1. Confirm intact furcation anatomy on the radiograph. Cow Horn forceps are contraindicated where furcation involvement is severe or roots appear fused.

2. Use a periosteal elevator to expose the furcation area and sever the gingival attachment before placing the beaks.

3. Seat both beak tips simultaneously at the furcation, applying equal bilateral pressure.

4. Use a controlled pump handle motion, pressing apically and releasing slightly, progressively seating the beaks deeper with each cycle.

5. Once the tooth mobilizes, deliver in a buccal or lingual direction as root anatomy permits.
   When Cow Horn forceps should not be used: Teeth with fused roots, Glickman Class III or IV furcation pathology, or significant root dilaceration are poor candidates. In these cases, applying Cow Horn forceps risks splitting the alveolar bone or fracturing roots. A surgical approach with dedicated surgical instruments (sectioning the tooth before extraction) is the appropriate response when Cow Horn mechanics fail to engage.

Universal Forceps: The Multi-Quadrant Option

Direct answer: Universal forceps feature symmetrical, non-arch-specific beak designs, most commonly bayonet-pattern or bird-beak configurations, that can be used across multiple quadrants without changing instruments. Universal forceps are best suited for root tips, root fragments, impacted teeth with limited access, and situations where atypical anatomy or crown compromise makes arch-specific forceps impractical.
Universal forceps are defined by what they are not: optimized for a single tooth type or arch. Their beaks are symmetric and non-directional, and their handles are typically configured to reach teeth that arch-specific instruments cannot access, such as upper third molars, root tips in deep sockets, and impacted or semi-impacted teeth near or below the alveolar crest.
The bayonet design is the most recognizable universal pattern. The handle curves away from the beak axis in two planes, allowing the clinician's hand to clear the occlusal plane while the beaks engage deep in the arch. This geometry is indispensable for upper third molars, where conventional straight or molar forceps are blocked by the angle of the tuberosity and limited mouth opening.
Universal forceps are the contingency instrument. When a crown fractures mid-extraction, when a root tip retreats apically, or when limited mouth opening prevents proper seating of a molar forceps, the universal bayonet provides continued access and control. It does not replace arch-specific instruments for routine cases. It fills the gap when routine becomes difficult. Every extraction tray should include one. Treating it as a fallback rather than a first choice keeps instrument selection disciplined and case outcomes predictable.
Clinical technique with Universal forceps:

1. Seat the beaks as far apical as possible, using the bayonet angle to guide the tips past the occlusal plane.

2. Apply gentle apical pressure to maximize root engagement before any lateral movement.

3. Use whichever motion the root anatomy allows: buccal-lingual rocking for multi-rooted morphology, controlled rotation for single conical roots.

4. For root tips, pair the universal forceps with an apical pick. Root-tip retrieval rarely succeeds with forceps alone.

5. Deliver in the path of least resistance, guided by the preoperative radiograph.
   Universal forceps are the better choice when crown integrity is severely compromised, access is limited by trismus or anatomy, tooth position is atypical, or root-tip retrieval is the primary task. Arch-specific forceps are the better choice when the tooth is intact, root anatomy is predictable, and normal access is available. Using universal forceps as the default for all extractions, a pattern some students adopt to avoid learning the full instrument set, trades mechanical advantage for convenience. That trade-off shows up in longer procedure times and higher complication rates. For smaller mouths and primary teeth, our pediatric extraction forceps are designed around deciduous tooth anatomy.

Quick-Reference Forceps Selection Guide

Selecting the right dental extraction forceps takes seconds once the pattern is familiar. This table summarizes the six instruments covered in this guide:

Common Errors in Forceps Selection and How to Correct Them

The most frequent errors in dental extraction forceps selection fall into three categories.
Wrong arch selection. Using #150 beaks on mandibular teeth, or #151 on maxillary teeth, misdirects force and prevents proper apical seating. The handle angle alone should make this apparent before the forceps reaches the patient's mouth.
Right forceps, wrong side. Using #88R on the upper left, or #88L on the upper right. This produces a beak geometry mismatch, where the palatal beak angles away from the palatal root instead of engaging it. One visual check before placement prevents this entirely.
Forcing the wrong instrument. The most consequential error is recognizing that an instrument is not seating correctly and continuing anyway. Every experienced clinician has felt the resistance that signals the wrong tool. The correct response is to stop, remove the instrument, reassess, and switch, not to increase force. The anatomy does not accommodate errors in patience.
A fourth error is less about selection and more about maintenance: placing worn or improperly sterilized forceps on the tray. Dull beaks do not engage below the CEJ reliably, which produces the same result as choosing the wrong instrument. Keeping instruments organized and protected in dedicated cassettes and accessories is as important as reviewing your instrument selection.

What to Know Before Every Extraction?

Good forceps selection begins before the patient is seated. A current periapical radiograph is the single most important piece of information you can have before picking up any instrument. It reveals root number, root curvature, proximity to the inferior alveolar canal or sinus floor, and bone density, each of which influences which forceps you choose and how you apply it.
Confirm adequate local anesthesia before proceeding. Patient movement during forceps seating is one of the most common causes of beak malpositioning. A cooperative patient means a controlled procedure.
Review the tooth's structural integrity. A tooth with a heavily restored crown, active decay, or visible fracture lines needs a different forceps strateg
