Tooth Extractions create immediate space to alleviate tooth problems that it was indicated for. Often times extractions would be indicated near the site of the problem such as first premolars for severe front teeth crowding. This can save time to resolve dental problems that the extractions were indicated for.
Dental extractions create fairly large spaces ranging 6.5-7.5mm on average for premolar extractions for severe dental bite problems. Non-extraction methods of creating space are generally less and may not resolve very major dental bite problems.
If you have teeth that of poor quality, example large decays or defective fillings or in need of root canal treatment, extraction of poor quality teeth to create space can be a win-win situation of having pretty straight teeth and 1 less tooth to restore/ repair.
Non-extraction methods of creating space are generally used to create small or modest amounts of space. The best advantage of this method is that good-quality adult teeth are not removed! It may take some time to create space via certain methods such as moving teeth backwards (distalization) or arch expansion.
IPR= InterProximal Reduction and helps to create generally modest 0.2 to 0.5mm of space per side of the tooth and care must be taken to keep any IPR within enamel. IPR can also help to reduce the size of 'black gum triangles', improve the contact between teeth and improve/ balance the shape of teeth.
There are many considerations before deciding on the best method for creating space. The face and lip profile, growth potential, jaw relationships, deep/ open bites and bony widths all need to be carefully studied before coming to the conclusion of extraction vs non extraction.
Do sit with your Orthodontist or dental provider to discuss your options and alternatives before starting treatment.
