Dental infections

are the most

common infections

known to man

Dental treatment is frequently performed on an

urgent / emergency basis as a result of an active dental infection or

injury producing pain and/or swelling

Bleeding following tooth extraction

Rate of post operative bleeding ( 7% to 10% 3rd molars)

Usually associate with difficult extraction long surgical procedures

Usual bleeding sources 7 % arterial 72 % soft tissue

Bleeding – Complication of tooth extraction

Bleeding – Complication of tooth extraction

Pressure placed directly over the bleeding site

typically stops bleeding

Swelling after tooth extraction is not

uncommon

Jaw Stiffness (Trismus) Complication of tooth

extraction

Jaw pain following tooth

extraction1st 24 hours

usually associated with surgery

24 to 36 hours post op

Constant dull throbbing spontaneous pain may be

associated with

DRY SOCKET

TREATMENT:

1. Gently irrigate (saline)

2. Place sedative dressing

Dry Socket

(1 – 30% for 3rd molars)

Post Op Infections(0.06 – 4.3% for 3rd molars)

Many extractions are performed on and

urgent basis due to pain from an infected

tooth

Infections may spread to adjacent tissue spaces

• Sinus and orbital cavities• Inter muscular spaces of the jaw• Floor of the mouth• Parapharyngeal spaces

Altered Nerve Function (0.02 – 7.1% for 3rd molars)

The most frequent nerve injury

Lingual and Inferior Alveolar / Mental Nerves

Midline tongue piercing relatively blood-free especially when good compression

hemostasis is used (tongs)

Significant bleeding may

be encountered with with piercing more

Direct pressure whether applied manually or with sutures generally arrests bleeding
