There is a way to save the missing upper teeth from shifting for too long; the missing upper teeth from shifting for too long may be the neighboring teeth shifting, or it may be the opposing dentition elongation shifting, according to the different situations to take orthodontic treatment, alignment treatment or amputation of the crown treatment and other measures. 1. Adjacent teeth displacement: the upper teeth missing teeth for too long will make the adjacent teeth to the missing teeth gap displacement, so that the missing teeth gap becomes narrower, affecting the denture repair. At this time, orthodontic treatment is feasible, aligning the neighboring teeth, leaving enough space for denture repair. 2. Maxillary teeth elongation displacement: the upper teeth are missing for too long will make the maxillary teeth elongation displacement, so that the height of the missing teeth gap is reduced, affecting the denture repair. At this time, the maxillary teeth can be adjusted to the dental treatment, reduce the dental plane; if the elongation height is too long to adjust the dental effect is not good, it is feasible to cut off the crown after root canal treatment to reduce the height of the elongated crown, leaving enough space for denture repair. Upper teeth missing teeth too long displacement, should be timely consultation, perfect examination, by professional physicians to give regular treatment.
