It may occur in different tissues located in various areas of the body. <\/p>    <p>Tooth resorption, including root resorption, involves parts of the tooth being broken down by cells called osteoclasts.<\/p>    <p>This process can occur internally, in the tooth pulp, or externally, affecting the cementum or less commonly enamel. The latter is more common. Occasionally, external root resorption may occur alongside internal resorption.<\/p>    <p>Tooth resorption often begins on the external surface of the tooth and may gradually move inwards. In addition to losing part of a tooth, or ending up with a <a href=\"https:\/\/www.dentaly.org\/en\/oral-health\/dead-tooth\/\" target=\"_blank\" rel=\"noreferrer noopener\">dead tooth<\/a>, you may also develop gum inflammation and other symptoms characteristic of this condition.<\/p>    <p>Here are some other quick facts about tooth resorption before we look at it in more detail:<\/p>    <ul class=\"wp-block-list\"> <li>People with resorption usually feel no pain and are asymptomatic.<\/li>    <li>External resorption can be misdiagnosed; a second opinion may be necessary.<\/li>    <li>Root canal therapy may help treat internal resorption, but if there is a large defect, the <a rel=\"noreferrer noopener\" href=\"https:\/\/www.dentaly.org\/en\/chipped-tooth-repair\/\" target=\"_blank\">tooth may fracture or break<\/a> and fail to function.<\/li> <\/ul>    <h2 id=\"types-of-tooth-resorption\" class=\"wp-block-heading\">Types of tooth resorption<\/h2>    <p>Depending on the exact area affected, resorption of the tooth is divided into two main classifications: <strong>internal tooth resorption<\/strong> and <strong>external tooth resorption<\/strong>.<\/p>    <h3 class=\"wp-block-heading\">Internal tooth resorption<\/h3>    <p>As indicated by the name, internal resorption affects the insides of the teeth. It is relatively uncommon compared to external resorption and <a rel=\"noreferrer noopener\" href=\"https:\/\/www.ncbi.nlm.nih.gov\/pmc\/articles\/PMC4920650\/\" target=\"_blank\">occurs in men more often than in women<\/a>. <\/p>    <p>Internal resorption is also more prevalent in people who have recently experienced dental trauma or undergone extensive oral surgery. For example, tooth autotransplantation (repositioning of an erupted or impacted tooth in another location to replace a missing tooth in the same person).<\/p>    <p>Most patients suffering from <strong>internal resorption<\/strong> are unaware of this problem because it&#8217;s hard to see from the outside. Therefore, most cases of internal resorption are normally detected via X-rays performed as a part of a routine dental examination.<\/p>    <p>On an X-ray, an internally resorbing tooth will show a larger pulp chamber or canals replacing the surrounding dentin, in comparison with neighbouring teeth.<\/p>    <h3 class=\"wp-block-heading\">External tooth resorption<\/h3>    <p>This problem is more common than internal resorption and can affect any part of the tooth. When it begins with the cementum around the root, it may be called <strong>external root resorption<\/strong>.<\/p>    <p>External resorption may appear on the outer surface of the tooth in the form of deep chips or holes. Resorption that extends to the roots of the tooth can be seen in an x-ray report as a flattening of the root tips as well as a reduction in their length.<\/p>   <div class=\"wp-block-image\"> <figure class=\"alignright size-large is-resized\"><img decoding=\"async\" src=\"https:\/\/www.dentaly.org\/en\/wp-content\/uploads\/sites\/3\/2020\/05\/Depositphotos_301600696_s-2019.jpg\" alt=\"resorption tooth definition\" class=\"wp-image-12691\" width=\"300\" \/><figcaption class=\"wp-element-caption\">Tooth root resorption occurs in a number of ways<\/figcaption><\/figure><\/div>   <p>External resorption is further classified into several types:<\/p>    <h4 class=\"wp-block-heading\">Inflammatory<\/h4>    <p>External inflammatory resorption is normally caused by a prolonged trauma of the tooth ultimately giving rise to pathological resorption. <\/p>    <p>Some of the most common causes of this type of resorption include the drying of the root surface after a trauma, previous surgery, injury to the periodontal ligament (PDL), pressure, or complete exposure of the dentine tubules.<\/p>    <h4 class=\"wp-block-heading\">Surface<\/h4>    <p>This type of resorption normally is usually not too severe and is often diagnosed after an incidental finding on an x-ray. Also known as transient inflammatory resorption. It is caused by the presence of pressure, such as an impacted tooth or cyst. it normally heals upon removal of the cause and only requires proper monitoring. <\/p>    <p>The common causes of this condition include a limited, localised injury to the root of the tooth or the surrounding area. Following injury, the affected area undergoes osteoclastic activity (the eating away of bone by cells) for two to three weeks before healing begins. <\/p>    <p>If the problem is only limited to the cementum or enamel, it is possible to achieve complete healing. However, if the problem involves dentine, re-contouring will be needed.<\/p>    <h4 class=\"wp-block-heading\">Cervical<\/h4>    <p><strong>External cervical resorption<\/strong> refers to a localised lesion in the <a rel=\"noreferrer noopener\" href=\"https:\/\/www.ncbi.nlm.nih.gov\/pmc\/articles\/PMC5125167\/\" target=\"_blank\">cervical region of the tooth<\/a>, just above where the root begins. The problem rarely extends to the pulp and is often caused by prolonged trauma leading to a horizontal and vertical growth of the lesion following periodontal treatment, trauma, or tooth whitening.<\/p>    <h4 class=\"wp-block-heading\">Replacement<\/h4>    <p>This type of root resorption involves the resorption of the tooth tissue followed by a complete replacement with bone. This leads to the elimination of the periodontal ligament space around the tooth and complete fusion between the tooth and surrounding bone.<\/p>    <p>The reason why this happens is not well understood. However, most orthodontic and dental experts believe that the process begins soon after the obliteration of the PDL and the close approximation between the tooth and the bone. <\/p>    <p>The damage to the PDL disrupts the release of the protective regulator that helps prevent root resorption. This encourages the osteoclasts (bone-destroying cells) to completely resorb the tooth tissue and replace it with bone.<\/p>    <p>Learn more about tooth resorption types in this video:<\/p>    <figure class=\"wp-block-embed is-type-video is-provider-youtube wp-block-embed-youtube\"><div style=\"display: contents;\" >  <div data-mode=\"normal\" data-oembed=\"1\" data-provider=\"youtube\" id=\"arve-youtube-rxlflc6r11q\" class=\"arve\"> \t<div class=\"arve-inner\"> \t\t<div class=\"arve-embed arve-embed--has-aspect-ratio\"> \t\t\t<div class=\"arve-ar\" style=\"padding-top:56.250000%\"><\/div> \t\t\t<iframe allow=\"accelerometer &#039;none&#039;;autoplay &#039;none&#039;;camera &#039;none&#039;;ch-ua &#039;none&#039;;clipboard-read &#039;none&#039;;clipboard-write;display-capture &#039;none&#039;;encrypted-media &#039;none&#039;;gamepad &#039;none&#039;;geolocation &#039;none&#039;;gyroscope &#039;none&#039;;hid &#039;none&#039;;identity-credentials-get &#039;none&#039;;idle-detection &#039;none&#039;;keyboard-map &#039;none&#039;;local-fonts &#039;none&#039;;magnetometer &#039;none&#039;;microphone &#039;none&#039;;midi &#039;none&#039;;payment &#039;none&#039;;picture-in-picture;publickey-credentials-create &#039;none&#039;;publickey-credentials-get &#039;none&#039;;screen-wake-lock &#039;none&#039;;serial &#039;none&#039;;sync-xhr;usb &#039;none&#039;;window-management &#039;none&#039;;xr-spatial-tracking &#039;none&#039;;\" allowfullscreen=\"\" class=\"arve-iframe fitvidsignore\" credentialless data-arve=\"arve-youtube-rxlflc6r11q\" data-lenis-prevent=\"\" data-src-no-ap=\"https:\/\/www.youtube-nocookie.com\/embed\/RXlFLc6r11Q?feature=oembed&amp;iv_load_policy=3&amp;modestbranding=1&amp;rel=0&amp;autohide=1&amp;playsinline=0&amp;autoplay=0\" frameborder=\"0\" height=\"0\" loading=\"lazy\" name=\"\" referrerpolicy=\"strict-origin-when-cross-origin\" sandbox=\"allow-scripts allow-same-origin allow-presentation allow-popups allow-popups-to-escape-sandbox\" scrolling=\"no\" src=\"https:\/\/www.youtube-nocookie.com\/embed\/RXlFLc6r11Q?feature=oembed&#038;iv_load_policy=3&#038;modestbranding=1&#038;rel=0&#038;autohide=1&#038;playsinline=0&#038;autoplay=0\" title=\"\" width=\"0\"><\/iframe> \t\t\t \t\t<\/div> \t\t \t<\/div> \t \t \t <\/div> <\/div><\/figure>    <h2 id=\"what-causes-tooth-resorption\" class=\"wp-block-heading\">What causes tooth resorption?<\/h2>    <p>There are several factors that may lead to resorption of teeth. The most common cause of external resorption is trauma or pressure on the teeth. <\/p>    <p>For example, prolonged tooth grinding, using excessive pressure by orthodontic appliances like braces for a long time or the presence of an impacted tooth or cyst. In some cases, the resorption can occur without a known cause (Idiopathic resorption).<\/p>    <p>In the case of internal resorption, the most common cause is trauma to the teeth following an <a rel=\"noreferrer noopener\" href=\"https:\/\/www.dentaly.org\/en\/tooth-decay\/\" target=\"_blank\">untreated dental cavity<\/a> or <a rel=\"noreferrer noopener\" href=\"https:\/\/www.dentaly.org\/en\/tooth-abscess-information\/\" target=\"_blank\">tooth abscess<\/a>.<\/p>    <h3 class=\"wp-block-heading\">Are there any complications?<\/h3>    <p>Without proper treatment, resorption may lead to a number of complications which include:<\/p>    <ul class=\"wp-block-list\"> <li>Infection<\/li>    <li>Discolouration and weakening of teeth<\/li>    <li>Difficulty in extracting the involved tooth due to fusion with bone<\/li>    <li>Crooked teeth<\/li>    <li>Chipping<\/li>    <li>Cavity-like holes<\/li>    <li><a rel=\"noreferrer noopener\" href=\"https:\/\/www.dentaly.org\/en\/oral-health\/stop-receding-gums\/\" target=\"_blank\">Gum recession<\/a><\/li>    <li>Complete loss of teeth<\/li>    <li><a rel=\"noreferrer noopener\" href=\"https:\/\/www.dentaly.org\/en\/toothache-causes-treatment\/\" target=\"_blank\">Toothache<\/a><\/li> <\/ul>    <h2 id=\"symptoms-of-tooth-resorption\" class=\"wp-block-heading\">Symptoms of tooth resorption<\/h2>   <div class=\"wp-block-image\"> <figure class=\"alignright size-full\"><img decoding=\"async\" src=\"https:\/\/www.dentaly.org\/en\/wp-content\/uploads\/sites\/3\/2021\/08\/Pulpitis-pain.jpg\" alt=\"internal resorption tooth\" class=\"wp-image-25412\" \/><figcaption class=\"wp-element-caption\">Symptoms from tooth resorption can include pain, redness and swelling<\/figcaption><\/figure><\/div>   <p>When it comes to root resorption, there is no clear set of symptoms. In some cases, the patient may not notice the problem for years. However, the symptoms soon begin to appear as the resorption worsens.<\/p>    <p>The most common <strong>symptoms of tooth resorption<\/strong> include:<\/p>    <ul class=\"wp-block-list\"> <li>Pain beginning from the crown, root, or the inside of the tooth<\/li>    <li>Redness and swelling of the gums<\/li>    <li>Unequal spacing between the teeth<\/li>    <li>Brittle teeth<\/li>    <li>Development of holes in the teeth<\/li>    <li>Pink spots on the enamel<\/li> <\/ul>    <h2 id=\"diagnosis\" class=\"wp-block-heading\">Diagnosis<\/h2>    <p>The diagnosis of root resorption basically depends on the part of the tooth affected. In the case of internal resorption, the dentist may notice dark spots inside the tooth on an X-ray. This is normally followed by a detailed dental history to confirm any past injuries or dental procedures that might have led to this problem.<\/p>    <p>A dentist may also perform a physical inspection of the tooth. This normally includes taking x-rays and touching the affected teeth with cold and heat in order to assess the condition of the pulp and the extent of resorption. <\/p>    <p>External absorption can be seen with the naked eye if it occurs in the crown or cervical part of the tooth. X-rays are needed in case of root resorption, in which the external anatomy of the root is altered ranging from small indentations on the root surface to apex resorption and shortening of the root. Also, root fusion with the surrounding bone may be seen. <\/p>    <p>The steps of diagnosis are similar to those of internal absorption.<\/p>    <h2 id=\"tooth-resorption-treatment\" class=\"wp-block-heading\">Tooth resorption treatment<\/h2>    <p>Treatment for root resorption varies according to the particulars of each case. The first step is the removal of the cause such as the pressure of an impacted tooth or the adjustment of orthodontic force. <\/p>    <p>If minor resorption has occurred, the dentist will monitor the tooth over a period of time and you may not require any further dental care. However, if more of the tooth structure has been affected, a filling or root canal therapy might be the treatment of choice.<\/p>    <p>In the case of internal resorption, root canal therapy and crown coverage should be performed in order to stop the progression of the resorption and protect the remaining tooth structure.<\/p>    <p>The treatment of apical resorption (where the root apex is resorbed) requires root canal treatment and &#8220;Apicectomy&#8221;, which is an endodontic surgery performed to remove the apical portion of the root in cases of infection-induced root resorption.<\/p>    <p>In the case of widespread damage, it may be necessary to extract the affected teeth.<\/p>   <div class=\"wp-block-image\"> <figure class=\"alignright size-large is-resized\"><img decoding=\"async\" src=\"https:\/\/www.dentaly.org\/en\/wp-content\/uploads\/sites\/3\/2020\/05\/Depositphotos_209142626_s-2019.jpg\" alt=\"root resorption treatment\" class=\"wp-image-12688\" width=\"300\" \/><figcaption class=\"wp-element-caption\">Various dental techniques can help restore your smile <\/figcaption><\/figure><\/div>   <h2 id=\"conclusion\" class=\"wp-block-heading\">Conclusion<\/h2>    <p>Root resorption in adults is usually indicative of an underlying tooth injury or infection that may cause long-lasting damage or even lead to the complete loss of the affected tooth.<\/p>    <p>Resorption is usually discovered during routine dental examinations.
