the number of pets continue to increase, the need for veterinarians to treat
dental diseases also continues to rise, and pet owners are paying all the more
attention to the diagnosis and treatment of their pet’s dental diseases. In
order to deepen everyone’s understanding of pet dental diseases and to help
others quickly learn key points of tooth extraction, RWD has invited Teacher
Liu Guangchao, an experienced professional in this industry, to explain how to
extract a canine tooth in detail. Detailed points have been made clear and good
information is abundant! We recommend you save this article to view again and
is no exaggeration in saying that small animal dental diseases may be the most
common to clinicians. Although each doctor may excel in different ways, and might
place a different level of attention on dental diseases, it is undeniable that dental
diseases will have an adverse affect on an animal’s quality of life and the
bond between people and their pets.
on the experience of our hospital and many foreign veterinarians, the
prospect of using dentistry as a clinical entry point has gradually emerged.
There are many ways to treat various dental issues. Concerning periodontal
disease, the most common dental disease in dogs and cats, the skill of tooth
extraction has stood out as the most effective method, and it is implemented in
the clinical front line much more frequently than other advanced dental
to my experience, the ratio of dental extraction versus other advanced dental
treatment is about 15-20:1. Advanced dental treatment goes hand in hand with
vigorous repeated training, over abundant and complicated equipment, high
treatment costs, and strict procedures of review. However, tooth extraction
is the ultimate solution to many dental problems. If tooth extraction is
mastered well, it can increase operation speed and reduce the rate of
complications, thereby becoming a great help to clinicians. The ultimate
goal of a tooth extraction is to remove the tooth completely and cause as
little trauma as possible to the surrounding tissue.
Introduction to Canine Tooth Extraction
The tooth is able to be stable within the
socket you will extract it from by means of the periodontal ligament, providing
85% of retention, and the gingiva surrounding the tooth, providing the
remaining 15% of retention. Therefore, the first step of tooth extraction is to
use the #11 or #15 blade to cut along the gingival crevasse to the ridge of the
alveolar bone. Be careful not to tear the gingiva during this operation.

area is the periodontal ligament

roots of the canine teeth are longer, it is necessary to remove 1/3-1/2 of the
long buccal bone plate to take them out. Therefore, a full-thickness gingival
flap must be made to expose the underlying alveolar bone.
In the picture below, the pink layer is
the gingival mucosa and the green layer is the periosteal layer. Between these
two is the submucosa, which includes blood vessels and nerve tissue. A gingival
flap containing all three of these layers is called a full-thickness gingival
flap. A triangular full-thickness gingival flap is the most suitable gingival
flap for canine tooth extraction. The main advantages include less stitching,
sufficient area exposure, and shorter operation time.
The triangular gingival flap can be made
by using the following steps as shown in the picture below. It’s worth noting
As step ③ is performed, the blade should
be used to cut in the direction indicated by the arrow, the incision should be
able to expose the root of the canine tooth, and the depth of the cut should be
made directly against the alveolar bone, making sure to cut to the base of the
While using a periosteal elevator to elevate
the gingival flap, it should be made sure that the junction of ② and ③ is complete, and that the elevated
gingival flap should contain the periosteal layer.
To the right is a picture of a lifted
full-thickness triangular flap as well as the lower buccal alveolar bone.
Notice that the length of the apical incision enables 1/3-1/2 of the root alveolar bone to be exposed
Use a high-speed handpiece and a round bur or a fissure bur with the aid of sufficient cooling water to remove the alveolar bone to a root length of 1/3-1/2, exposing the root surface of the cementum
Be certain to avoid damaging the gingival
flap with the high-speed bur. When bleeding occurs, gauze can be used to stop
Instruments that are correctly inserted into the periodontal ligament can be let go and will remain fixed in the periodontal ligament without being held on to
Use your left hand to hold the head securely and protect the gingiva while you use your right hand to correctly hold the dental elevator and insert it into the space of the periodontal ligament
Next, instruments are needed to destroy
the periodontal ligament. The way a tooth is used daily determines that it is
good at withstanding the short-term yet high-strength force of biting. However,
under long-term low-strength force, the periodontal ligament will wear out and
thus easily be torn.
Another aspect is that the space of the
periodontal ligament is very narrow. When a tooth extraction tool is used that is
not sharp enough or that does not correctly match the shape of the tooth, it will
become difficult to insert the instrument into the space of the periodontal
ligament and to directly destroy it, or more force will be required for
insertion. This will put pressure on the surrounding alveolar bone or cause the
tooth you are extracting to break, and may even cause the instrument to slip
out of your hand causing damage to surrounding important tissue.
Based on the above reasons, the
selection and maintenance of extraction tools, successful insertion into the
periodontal ligament, as well as the correct method of applying force are
important prerequisites for successful extraction.
The author’s view of operation
◆ Use instruments that are sharp and
suitable to the shape of the root of the tooth. Instruments should be sharpened
and maintained daily.
◆ Hold instruments correctly and be
familiar with the use of dental luxators and elevators. Ensure that your
instrument is inserted into the periodontal ligament. When inserted correctly,
the dental elevator or blade can be fixed in the periodontal ligament space, the
instrument will stay in place even if you let it go. Another indication that
you have correctly inserted your instrument, is that the tooth will slightly
tilt toward the side of applied force.
◆ Abstain from the method of quickly
twisting your wrist back and forth to insert the dental elevator. Instead,
incorporate a method of calm and steady force. When the tooth slightly tilts
from the pressure, continue to apply force 15-20 seconds. At this time, you
will find an increase in the looseness of the tooth.
The most important instruments used in
tooth extraction are the dental elevator and luxator, the main difference between
these lies in their shape and method of use.
◆ With or without wings
◆ The shape of it’s edge should fit the tooth
◆ After insertion into the periodontal
ligament, rotate and hold for 30 seconds
◆ Tears periodontal ligament
◆ Causes greater damage to alveolar bone
◆ Thin and sharp tip
◆ Cuts periodontal ligament with up and
◆ Causes less damage to periodontal tissue
◆ Relatively less postoperative pain
methods of operating the dental luxator
It is usually recommended to use the
dental luxator to extract teeth. A dental luxator is sharper, causing less
damage to the surrounding tissues and resulting in faster operation. The dental
elevator and luxator can also be used together. Extraction forceps should only
be used after the tooth is clearly loose. If the tooth is not loose enough, you
should continue to use the elevator or luxator. Don’t use dental extraction
Clamp the dental extraction forceps to the
neck of the canine tooth, gently lift and maintain constant tension. Based on
the situation, you can consider applying rotational force. The canine teeth are
most often pulled out gradually within 5-10 seconds.
Extract the canine tooth and clean the alveolar
Use surgical tweezers to gently hold the gingiva checking the size and tension of the mucosal flap
When the mucosal flap has a lot of tension,
the wound is more likely to open during the healing process. Concerning the
full-thickness gingival flap mentioned above, the periosteal layer is tougher
but has poor elasticity, whereas the mucosal layer has good elasticity. At this
time, the periosteal layer can be cut from below the mucosal and gingival
junction to release tension, making sure that before suturing there is no
tension on the incision line.
Deduction of mucosal flap

·Touch the edges of the alveolar bone and use
a round bur or diamond bur to remove sharp bone points and diseased alveolar
·Rinse the extraction socket to ensure that
there is no tartar or pieces of broken bone

-Saline solution or salt water
-Avoid using an air polisher to blow air into

Before suturing, it is recommended to
check the edges of the alveolar bone to confirm whether they are smooth or not.
Excessively protruding alveolar bone may damage the gingival flap. At the same
time, it’s also necessary to remove the epithelial tissue from the edges of the
wound. This will ensure fresh bleeding that will promote healing as the wound
Use 4/0 absorbable single-strand sutures to proceed with figure-of-eight or single interrupted sutures, spaced at 2-3 mm
Appearance after stitching
The extraction of a canine tooth usually comes
with certain challenges. It is recommended that beginners should first become proficient
in the removal of mandibular incisors and maxillary 1-3 incisors, and then
consider canine extraction.
