Tooth Implants Problems What Are The Potential Problems Of A Missing Tooth?

What are the potential problems of a missing tooth? - tooth implants problems

I just made my lower left first molar and my dentist told me to do nothing. I have found the research on the missing teeth and that there are enormous problems associated with it, such as moving or drifting of teeth, bone problems, the increasing deterioration. My dentist has not to worry, because the teeth can slip. I am confused and worried. I see a dentist again after the rubber is cured for a prosthesis to prevent drift? I can not afford to be a bridge or an implant now. Is it necessary to say so as soon as possible, right, it was not necessary to do something?
