Crown lengthening can also be achieved orthodontically (using braces) by extruding the tooth. Crown lengthening is done for functional and/or esthetic reasons. Functionally, crown lengthening is used to: 1) increase retention and resistance when placing a fabricated dental crown , [ 2 ] 2) provide access to subgingival caries , 3) access ...
It is performed near the completion of the orthodontics and is shown to be effective in preventing the relapse of teeth. To perform this procedure, there is the surgical cutting of disrupted transseptal fibres by making a gingival crevicular incision under local anesthetic after orthodontic alignment. [ 2 ]

The process of preparation usually involves cutting the tooth with a rotary dental handpiece and dental burrs, a dental laser, or through air abrasion (or in the case of atraumatic restorative treatment, hand instruments), to make space for the planned restorative materials and to remove any dental decay or portions of the tooth that are ...
Crown to root ratio is the distance from the occlusal/incisal surface of the tooth to the alveolar crest in relation to the length of root within the bone. The minimum ratio of crown to root is considered to be 1:1, although the most favourable is a crown:root of 2:3. As the proportion of tooth supported by bone decreases, the lever effect ...
Electric toothbrushes are, simply put, more equipped to clean your teeth than a regular toothbrush, in the sense that they make teeth brushing a less labor intensive process on your end.
