The aim of extraction is to take out the designated tooth
so as to remove the root cause of the oral problem, or to pave for the
subsequent dental treatments.
- A badly decayed/broken/fractured tooth
that cannot be restored, or even turns into a breeding ground for
- An extremely mobile tooth resulting from
- A tooth to be extracted for pathological
reasons, e.g. a tooth involved in tumor
- A tooth fails to erupt in a right place and causes damages and
inflammation to the nearby tissues
- A tooth that is abnormal in its appearance and structure
- A tooth to be extracted for orthodontic
- A tooth that may bring about other health
problems, e.g. a tooth with an exposed pulp will increase the chance
of bacterial infection in the heart of a patient with rheumatoid
This is suitable for most of the
normally erupted tooth.
Local anesthesia is given and that makes the tooth and the
surrounding tissues numb.
- Then an appropriate forcep or
dental instrument is used to rock the tooth gently and pull
the loosened tooth out of the mouth.
This is used when the tooth cannot
be extracted by the usual dental instrument. This includes
badly decayed/ fractured tooth, impacted tooth, crook-rooted
tooth, tooth in inelastic surrounding bone (common in elderly
- Local anesthesia is given and that
makes the tooth and the surrounding tissues numb or upon special
conditions, general anaesthesia is administered.
- Then the gum is cut open and reflected.
The covering bone is removed to expose the tooth. The tooth is
then rocked, loosened and pulled out or depends on the tooth
condition, it is cut into pieces and taken out bits by bits.
- The wound is rinsed and closed by
- About a week, the wound is inspected
and sutures are removed by the dentist.
The dentist will assess and discuss the
possible risks with the patient before proceeding extraction. Generally
speaking, the risks are minimal. The most common risk is fracturing
a tooth during extraction and may need surgical procedures to complete.
In some special occasions, after extraction,
a patient may bleed or may have wound swelling and pain continually
or even may have wound infection. So he/she should seek for dentist’s
help as soon as possible if the wound continues to have profuse bleeding,
abnormal swelling and pain for more than three days without any sign
of improvements, foul smell and pus running and if they have fever.
In the very rare occasion,
the nearby teeth, soft tissues or nerves may get damaged during
If this happened, the patient needs referral to specialist, e.g.
oral & maxillofacial surgeon for intensive care.
If the patients have other systemic diseases,
they should consult their medical doctors before extraction to understand
whether extraction can be proceeded, whether they need to take antibiotic,
steroid or adjust the dosage of anticoagulants, etc. in order to
ensure extraction can be done safely.
Nowadays, the advancements in medical technology,
anesthesia, analgesia and wound aftercare can greatly minimize the discomfort
after the extraction.
- After extraction, we should bite
on a gauze pack for 15 to 20 minutes to arrest bleeding from
the tooth socket. Meanwhile we should swallow the saliva normally.
In order to avoid bleeding from the socket again, the blood clot
in it should not be touched or disturbed.
Within 3 hours after extraction
- Do not rinse the mouth
- Do not eat hard or rough food
Within 24 hours after extraction
- Do not touch the blood clot by the tongue or fingers
- Do not drink alcohol containing beverages
- Do not attempt vigorous exercise
If there is profuse wound bleeding, the patient should immediately see
his/her dentist or depends on the bleeding severity, seek for emergency
care in the A&E
of the nearby hospitals.
- As the tissues nearby the extraction
site are still numb for some time, in order to avoid hurting
them, we should not eat within 3 hours after extraction, should
not bite or unduly touch that areas until the sensation is
- It is normal to have some swelling in the extraction site and
it would subside in about 3 days. We may follow the dentist’s
instruction to take the medication or use cold pack to relieve
- We should take the prescription as instructed.
- As food debris would trap in the tooth socket, 24 hours
after extraction, we should rinse the mouth with lukewarm
saline when finishing eating in order to keep the wound clean.
