Dental extraction is one of the most common dental procedures performed by dentists worldwide on a daily basis. Teeth are removed for a number of reasons.
Dental extraction is recommended when the tooth is damaged beyond repair from extensive decay, trauma or periodontal diseases. A sound tooth may sometimes be extracted to create space in the dental arches for orthodontic treatment. However, the contemporary orthodontic philosophy is now restricting teeth extraction to cases with severe facial profile protrusion.
Simple dental extraction is usually performed when the individual is awake. While the procedure is completely pain-free with the use of local anaesthetic injections, light pressure sensations are still slightly felt.
Simple dental extraction can be performed using the conventional “elevator and forceps” instruments, and is achieved completely above the gum. Teeth with straight roots and solid root structures can often be removed without being cut into pieces.
A tooth with multiple roots can be sectioned according to their root shapes to ease the removal. This is especially helpful if the multi-rooted tooth has roots that are not parallel to each other, or curved roots. Once the tooth is sectioned, the pieces can be elevated out of the sockets easily.
Common risks of dental extraction include pain, swelling, infection, dry socket, possible conversion into a surgical extraction, sinus perforation and nerve damage.
Individuals who are on anticoagulant therapies generally do not need to discontinue its use before the dental extraction. Warfarin users will be required to have their INR (International Normalised Ratio) tested before the procedure. Our highly skilled dentists take extra precautions to minimize post-operative complications.
There is currently no scientific evidence to support the use of systemic antibiotics in preventing post extraction infections. Chlorhexidine mouthwash is the gold standard for post extraction rinse to reduce the chances of local infection. Individuals with certain heart conditions (Eg. Repaired mitral valve), however, will benefit from antibiotic prophylaxis one hour prior to the procedure, reducing risk for subacute infective endocarditis.
