You have to remember that every single missing tooth in the mouth can lead to tilting of adjacent teeth, abrasion and loosening the others, too burdened with teeth, lengthening of opposing teeth or disturbances in the temporo - mandibular.
That is why it is so important to fill the gaps as quickly as possible tooth!
Depending on the conditions in the mouth you can be done in several ways.
Permanent restorations: crowns, bridges, veneers, crown - root inlays, inlays, onlays.
Removable dentures: complete and partial dentures, cast partials and overdentures.
