Is it OK to extract premolars?
Premolar extraction may be a necessary step to take during a preparation for an orthodontic procedure. Namely, removing premolars may be necessary and even inevitable in order to preserve and optimize the overall function of a patient’s teeth and jaw.
How much space is created from expansion or premolar extraction?
… Expansion is known to create space, where 0.5-0.7 mm of space is gained for every 1 mm of posterior arch expansion.
How long does it take for premolar extraction gaps to close?
It can take anywhere from a few months to a year to close extraction gaps. Gaps in teeth on the lower jaw tend to close slower than ones on the upper jaw.

What are the side effects of premolar extraction?
The procedure of premolar extraction and retract on of teeth is purported to cause structural changes in the facial form, namely the retrusion of the maxilla and mandible, loss of vertical dimension and reduction of the oral cavity, and health issues consequent to these structural changes, specifically.
How much space is gained by maxillary expansion?
CLICK TO ENLARGE PHOTO. As noted above, using the factor determined by Adkins et al., 0.7 times 14 mm of maxillary dental and skeletal expansion provides approximately 10 mm of space to aid with resolving the 12 mm of maxillary arch length deficiency.
How do I get more space in my dental arch?
Various mechanics have been used for space gaining in the arch, for example, multiple loops, open coil springs, molar uprighting springs,[1,2,3,4] and orthodontic separators for mild space creation. [5] The most common used mechanics for space opening/gaining is the use of nickel–titanium open/compression coil springs.
How do orthodontists close extraction gaps?
Braces work by pulling teeth into place with brackets, wire and elastic chain. Small elastic bands linked in a chain can move teeth together and close gaps. The coloured elastic chain fits over the brackets attached to teeth. Elastic chains can close gaps in as little as six weeks to six months.

How do you close out extraction spaces?
Two basic biomechanical strategies can be used to close extraction spaces: two-step retraction (TSR) or en masse retraction (ER). In the first step of TSR, only the canine in each quadrant is retracted. In the second step, all the incisors are retracted until the residual spaces are closed.
How long does it take for gap to close after tooth extraction?
Tissues and bone are cut underneath the gum line during surgical extractions. In the case of surgical extraction, your tooth hole will be fully or almost fully closed by 6 weeks after surgery. It may take several more months before the indentation fills in and the healing is complete.
