Dear Doctor, How long can anyone use a spacer ? Is it have any expire date. I heard that it has to change for every six months but it has 7 years of expire date please clarify it.
The company comes with an official timeline of 6 months of usability. However, a spacer in a good condition could be used for maximum duration of 1 year.
