It is common for teeth to move by 1mm after significant and consistent application of force but if you have a loose implant tooth in your all on 8 treatment, then you should immediately seek dental attention and treatment from a dental professional. Ignoring this may lead to your mouth experiencing a variety of dental problems in the near future. If the teeth are forcefully ejected, then you are at open risk of gum infection, tooth decay, and other similar dental problems.
