class=\"has-text-align-center wp-block-paragraph\">When an old front-tooth crown is removed and almost no natural tooth remains above the gum,<br>does the tooth always have to be extracted?<br>When a tooth is badly damaged and only the root remains, extraction may sometimes be necessary.<br>However, depending on the evaluation of the length and shape of the root, the extent of decay or fracture, the condition of the periodontal tissue and alveolar bone,<br>and whether the remaining tooth can be restored again,<br>there are also cases in which preserving the natural tooth<br>and treating it again with a crown can be considered.<\/p>\n\n\n\n<p class=\"has-text-align-center wp-block-paragraph\">Today I will introduce a case in which an old front-tooth restoration was removed and only the root remained,<br>and the remaining natural tooth was used to treat it again with a zirconia crown,<br>in a female patient in her 60s.<\/p>\n\n\n\n<div class=\"wp-block-rank-math-toc-block\"

wp-block-paragraph\">After removing the decayed areas of the remaining tooth, we used fiber posts and resin cores<br>to retain the cores for the final crowns.<br>A fiber post is a tooth-colored post made of fiber-reinforced material, and it is one of the materials that can be chosen, especially for front teeth,<br>where esthetics must be considered.<br>However, using a post does not necessarily make a tooth stronger<br>or prevent root fracture.<br>The long-term prognosis of a tooth is affected by many factors, such as the remaining natural tooth structure and root condition,<br>the shape and position of the post, the final crown, and the bite.<\/p>\n\n\n\n<h2 id=\"sec-6\" class=\"wp-block-heading has-text-align-center\" style=\"color:#0b9b3f;font-size:1.15rem\">There was not enough natural tooth structure for the crowns.<\/h2>\n\n\n\n<p class=\"has-text-align-center wp-block-paragraph\">In the photo taken after the posts and cores were made, most of the part visible above the gum<br>was core, and the actual natural tooth structure was not sufficiently exposed.<br>When restoring a tooth with a crown, it is important to secure<br>sound natural tooth structure that the final restoration can wrap around, that is, to consider the ferrule.<br>The tooth structure needed depends on the condition of the tooth and root, the final restoration, the bite,<br>and other conditions considered together.<br>To secure these restoration conditions, for this patient<br>we decided to perform crown lengthening as well.<\/p>\n\n\n\n<h2 id=\"sec-7\" class=\"wp-block-heading

lengthening, part of the tooth that had been located below the gum was exposed<br>to secure the restoration conditions for the final crowns.<br>In addition, because the surrounding gums showed swelling and inflammation at the first visit,<br>we also carried out the necessary gum treatment.<\/p>\n\n\n\n<figure class=\"wp-block-gallery has-nested-images columns-2 wp-block-gallery-7

the surrounding gums.<br>The initial temporary tooth focused less on completing the final shape of the front tooth and more on protecting the treated tooth and maintaining its form while the surrounding tissue healed.<\/p>\n\n\n\n<p class=\"has-text-align-center wp-block-paragraph\">After the gums had begun to heal, we readjusted<br>the temporary tooth to check the shape of the final crown.<br>We checked the length and width of the front teeth, their left-right shape, the gum line, and so on,<br>and reviewed what should be reflected in the final restoration.<\/p>\n\n\n\n<div

and width of the two front teeth and their relationship with the gum line.<br>Before treatment, the old joined PFM crowns, a dark color at the gum border,<br>and swelling of the surrounding gums were observed.<br>After removing the existing restoration, we checked the metal posts and the condition of the remaining tooth,<br>and re-treated the tooth with crown lengthening, a new core, and<br>zirconia crowns while preserving the natural tooth.<\/p>\n\n\n\n<h2 id=\"sec-11\" class=\"wp-block-heading has-text-align-center\" style=\"color:#0b9b3f;font-size:1.15rem\">Right after the

cases, rather than simply making the crown larger to hide the space,<br>the tooth shape, contact relationships, the condition of the gums and alveolar bone, oral hygiene, and so on should be

id=\"sec-13\" class=\"wp-block-heading has-text-align-center\" style=\"color:#0b9b3f;font-size:1.15rem\">Can every tooth with only the root remaining be saved?<\/h2>\n\n\n\n<p class=\"has-text-align-center wp-block-paragraph\">Not necessarily.<br>Whether a tooth with only the root remaining can be preserved depends on an overall evaluation of the length and shape of the root, whether it is fractured,<br>the extent of decay, the condition of the periodontal tissue and alveolar bone, the amount of sound tooth structure remaining, and whether<br>the tooth can finally be restored with a crown.<br>Depending on the case, crown lengthening or orthodontic extrusion may be considered, but if the condition of the root or the<br>periodontal tissue is poor, extraction may be more appropriate.<\/p>\n\n\n\n<p class=\"has-text-align-center wp-block-paragraph\">This patient's course was as follows:<br>removal of the old PFM crowns \u2192 removal of the existing metal posts<br>\u2192 evaluation of the remaining root and the possibility of restoration \u2192 removal of decay \u2192 fiber post and core<br>\u2192 crown lengthening and gum treatment \u2192 healing and shape check with a temporary tooth<br>\u2192 separate zirconia crowns \u2192 regular check-ups<br>We treated her in this order.<\/p>\n\n\n\n<p class=\"has-text-align-center wp-block-paragraph\">Therefore, rather than generalizing that a tooth with only the root remaining can always be saved, the key point of this case is that before extracting a tooth, it is important to evaluate whether the remaining root can actually be restored.<\/p>\n\n\n\n<p class=\"has-text-align-center wp-block-paragraph\">The photos of the treatment process and before and after treatment in this case are posted with the patient's consent.<br>Treatment methods and results vary from person to person. Whether a tooth with only the root remaining can be preserved depends on the remaining tooth structure, the length and shape of the root, whether it is fractured, the extent of decay, and the condition of the periodontal tissue and alveolar bone, and extraction may be necessary in some cases. After crown lengthening, pain, bleeding, swelling, and gum recession may occur, and even after crown treatment, fracture, loss of the crown, secondary caries, and periodontal problems may occur, so regular check-ups and care are necessary.<\/p>\n\n\n\n<p class=\"has-text-align-center wp-block-paragraph\">#BusanFrontToothCrown #SeomyeonFrontToothCrown #FrontToothCrown #FrontToothCrownRetreatment #RootOnlyTooth #BusanRootOnlyTooth #NaturalToothPreservation #SavingNaturalTeeth #BusanFrontToothTreatment #SeomyeonFrontToothTreatment #OldFrontToothCrown #PFMCrown #MetalPost #FiberPost #CrownLengthening #ZirconiaCrown #SeomyeonDentist #SmileDigitalDentalClinic<\/p>\n\n\n\n<h2 class=\"wp-block-heading has-text-align-center\">What should I check when considering front tooth crown retreatment?<\/h2>\n\n\n\n<p class=\"has-text-align-center wp-block-paragraph\">Over years of use, a front tooth crown is not just a momentary issue; the inside of the tooth and the gum condition can change together. When redoing a front tooth crown, you should first check the remaining tooth structure, the root and the gum condition, not just replace the crown. The method and duration of front tooth crown retreatment differ from case to case and are planned after an examination.<\/p>\n\n\n\n<p class=\"has-text-align-center wp-block-paragraph\">Related
