Each order includes ONE instalock for use with TGuard thumb sucking products only. Please select the kit type below.

Instalocks simplify the adjustment process, and allow you to keep the right settings when using our products to stop thumb sucking.


One replacement Instalock™. Note: please choose the Instalock™ corresponding to the kit that you’ve purchased, as they are not interchangeable.

Pictured first is the Instalock™ for our AeroThumb. The one with the flat back is the Instalock™ for our TGuard Classic.


Please note: An Instalock™ is included in all thumb sucking treatment kits. It is not included, nor required, for finger sucking kits such as FingerGuard or AeroFinger.
