Dental treatment over

Dental treatment for my right lower first molar was over yesterday at last.
To be fabricated my metallic filling inlay, asked I to increase the force between the contacting point with second molar, because the second molar that lost contacting with the first molar moves forward while the tame taking time treatment procedure, root canal treatment, root canal filling, constructing the base in the pulp chamber and the final inlay filling. Increased contacting distance would make the distal tooth move backward as before the treatment, just I felt some leaning forward phenomena judging from the change of tooth biting contact.
Trial setting without cementing in my mouth for a while, the second molar moved backward like the original position without feeling any inconvenience.
According to my poor study in Dentistry from Web sites, the sensors to know and introduce the signals to Cortex exist in Periodontal ligament also in masticatory muscles as Proprioceptor and Mechanoreceptor. And the sensing and it's reactions, so precise, so detailed and so accurate as not to be impossible to measure with recent sophisticated devices. For example, 7 micrometer thickness between the teeth can be noticed and in case of emergency like a small stone exist in the biting space, the signal come into the reflection mechanism, then immediately the jaw opens avoiding the enamel tissue fracture.
Dentist as the occupation must be very hard work to be done every day in such a complicated portion, because incredible concentration should be required to accomplish the work, precision and accuracy are the first there.
Just I don't want to do that however more reasonable guaranty of the amount might be obtained.
