The process of aligning teeth is technically called Orthodontics. It may be loosely defined as the science of moving teeth, aligning irregular, crowded or spaced teeth. Dentists who have expertise in this field are called Orthodontists. Anyone with mal-aligned or irregular teeth, crowded, overlapping teeth, or with gaps in between may require orthodontic treatment.
Different reasons for irregular teeth:-
Injury / accidents
Nail biting, etc.
Why Teeth Sometimes Need to be extracted?
In cases of severe crowding of teeth, there may not be any space available to align the teeth. Then it becomes necessary to extract some teeth to create enough space for the other teeth to get aligned correctly.
Whether Spaces created by Extracting Teeth will get filled?
As the teeth are moved for aligning them correctly, they move into the spaces created by the extraction.Hence the spaces created by extraction are completely filled once the teeth are aligned.
Will Teeth Move Back to their Original Positions after Treatment?
About 15-20% relapse is bound to occur over a period of time. Hence Orthodontists sometimes over-correct the alignment, anticipating the rebound. This can be minimized by following the instructions given to the patient during the maintenance phase of treatment.
