Decades of clinical research and advancements in materials, imaging, and techniques have made root canal treatment highly successful. Saving your natural tooth helps maintain normal biting force and sensation, protects neighboring teeth from excessive wear or strain, and supports your overall oral health.<\/p>\n<p>&nbsp;<\/p>\n\t\t\t\t\t<a role=\"heading\" aria-level=\"2\" tabindex=\"-1\"  id=\"fl-accordion--label-1\"><h3>When You Need a Root Canal?<\/h3><\/a>\n\t\t\t\t\t\t\t\t\t\t\t<button type=\"button\" id=\"fl-accordion--icon-1\" aria-expanded=\"false\" aria-controls=\"fl-accordion--panel-1\"><i>Expand<\/i><\/button>\n\t\t\t\t\t<p><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/www.aae.org\/patients\/wp-content\/uploads\/sites\/3\/2017\/11\/abscessed-tooth-254x300.jpg\" alt=\"\" width=\"254\" height=\"300\" \/><\/p>\n<h5>How to know if you need a root canal?<\/h5>\n<p>Endodontic treatment is necessary when the pulp, the soft tissue inside the root canal, becomes inflamed or infected. The inflammation or infection can have a variety of causes: deep decay, repeated dental procedures on the tooth, or a crack or chip in the tooth. In addition, a traumatic injury to a tooth may cause pulp damage even if the tooth has no visible chips or cracks. If pulp inflammation or infection is left untreated, it can cause pain or lead to an abscess.<\/p>\n<h5>What are the signs of needing a root canal?<\/h5>\n<p>There are a few symptoms that mean you might need a root canal-<\/p>\n<ul>\n<li>Severe pain while chewing or biting<\/li>\n<li>Pimples on the gums<\/li>\n<li>A chipped or cracked tooth<\/li>\n<li>Lingering sensitivity to hot or cold, even after the sensation has been removed<\/li>\n<li>Swollen or tender gums<\/li>\n<li>Deep decay or darkening of the tooth<\/li>\n<\/ul>\n<h5>What happens if you don&#8217;t get a root canal?<\/h5>\n<p>If left untreated, the localized infection in the tooth can progress into an abscess and spread to adjacent tissues, and in some cases can even be life threatening. If you are in need of a root canal, the infected pulp in the tooth needs to be removed.<\/p>\n<h5>When is it too late to get a root canal?<\/h5>\n<p>Waiting too long to get a root canal can oftentimes result in tooth loss. Many times with severe furcation, it might be too late for a root canal and the tooth would need to be extracted.<\/p>\n<h5>Can all teeth be treated endodontically?<\/h5>\n<p>Most teeth can be treated. Occasionally, a tooth can&#8217;t be saved because the root is severely fractured, the tooth doesn&#8217;t have adequate bone support, or the tooth cannot be restored. However, advances in endodontics are making it possible to save teeth that even a few years ago would have been lost. When non-surgical endodontic treatment is not effective, endodontic surgery may be able to save the tooth.<\/p>\n\t\t\t\t\t<a role=\"heading\" aria-level=\"2\" tabindex=\"-1\"  id=\"fl-accordion--label-2\"><h3>What are the signs of needing a root canal?<\/h3><\/a>\n\t\t\t\t\t\t\t\t\t\t\t<button type=\"button\" id=\"fl-accordion--icon-2\" aria-expanded=\"false\" aria-controls=\"fl-accordion--panel-2\"><i>Expand<\/i><\/button>\n\t\t\t\t\t<p>There are a few symptoms that mean you might need a root canal-<\/p>\n<ul>\n<li>Severe pain while chewing or biting<\/li>\n<li>Pimples on the gums<\/li>\n<li>A chipped or cracked tooth<\/li>\n<li>Lingering sensitivity to hot or cold, even after the sensation has been removed<\/li>\n<li>Swollen or tender gums<\/li>\n<li>Deep decay or darkening of the gums<\/li>\n<\/ul>\n\t\t\t\t\t<a role=\"heading\" aria-level=\"2\" tabindex=\"-1\"  id=\"fl-accordion--label-3\"><h3>Who Performs Root Canals?<\/h3><\/a>\n\t\t\t\t\t\t\t\t\t\t\t<button type=\"button\" id=\"fl-accordion--icon-3\" aria-expanded=\"false\" aria-controls=\"fl-accordion--panel-3\"><i>Expand<\/i><\/button>\n\t\t\t\t\t<h5>What kind of dentist does root canals?<\/h5>\nWhile all general dentists have been trained in root canals, endodontists are specialists in root canal treatment.

Sensitivity when biting or touching the tooth is common during the initial healing period. In the majority of cases, symptoms improve within three to five days. Prolonged or increasing pain is uncommon and should be evaluated by your endodontist.<\/p>\n<h5>\nWhat helps relieve pain after a root canal?<\/h5>\n<p>Over-the-counter medications, such as ibuprofen or acetaminophen, are often sufficient to manage post-treatment discomfort. Applying a cold compress to the outside of the cheek for short intervals can also help reduce swelling.

Some dentists may suggest to not eat for a few hours until the numbness in your mouth wears off so you don&#8217;t bite your cheek or tongue.<\/p>\n<h5>Can you drink alcohol after a root canal?<\/h5>\n<p>After a root canal procedure, you can eat and drink normally, including alcohol, once the numbness wears off.<\/p>\n<h5>Can you eat before a root canal?<\/h5>\n<p>You can eat normally before a root canal treatment.<\/p>\n\t\t\t\t\t<a role=\"heading\" aria-level=\"2\" tabindex=\"-1\"  id=\"fl-accordion--label-4\"><h3>Activities &amp; Habits<\/h3><\/a>\n\t\t\t\t\t\t\t\t\t\t\t<button type=\"button\" id=\"fl-accordion--icon-4\" aria-expanded=\"false\" aria-controls=\"fl-accordion--panel-4\"><i>Expand<\/i><\/button>\n\t\t\t\t\t<h5>Can I drive after a root canal?<\/h5>\n<p>Most root canal procedures are done using local anesthesia, meaning only the areas that are being treated will be numb during the course of the procedure. This means you are awake and aware during the process and can drive and operate machinery as you normally would immediately after the procedure is over.<\/p>\n<h5>Can you smoke after a root canal?<\/h5>\n<p>While you can smoke after a root canal, it is not recommended as quitting smoking is beneficial for your overall health. Smokers are nearly twice as likely to need root canals than non-smokers, and that number increases with more years of smoking.<\/p>\n<h2>\n\t\t\tRisks, Costs &#038; Options\t<\/h2>\n\t\t\t\t\t<a role=\"heading\" aria-level=\"2\" tabindex=\"-1\"  id=\"fl-accordion--label-0\"><h3>Longevity &amp; Effectiveness<\/h3><\/a>\n\t\t\t\t\t\t\t\t\t\t\t<button type=\"button\" id=\"fl-accordion--icon-0\" aria-expanded=\"false\" aria-controls=\"fl-accordion--panel-0\"><i>Expand<\/i><\/button>\n\t\t\t\t\t<h5>Can a root canal fail?<\/h5>\n<p>Root canals can fail for a variety of reasons, including a procedure that didn&#8217;t clean the canals to begin with, a breakdown of the crown or its inner sealant, or essentially anything that allows the tooth that previously had a root canal treatment to become infected inside the roots.<\/p>\n<h5>What causes an endodontically treated tooth to need additional treatment?<\/h5>\n<p>New trauma, deep decay, or a loose, cracked or broken filling can cause new infection in your tooth. This usually occurs if the tooth had a prior root canal treatment, often not performed by an endodontist. In some cases, the endodontist may discover additional very narrow or curved canals that were not treated during the initial procedure.<\/p>\n<h5>How long does a root canal-treated tooth last?<\/h5>\n<p>With proper restoration and good oral hygiene, a tooth that has had a root canal can last a lifetime. Studies show that root canal treatment has a success rate of more than 90%, and millions of teeth are successfully treated each year. The long-term outcome depends on factors such as the extent of the original infection, how quickly the tooth is restored with a crown or filling, and how well you care for your teeth afterward. Learn more about how long root canal-treated teeth last on our Longevity page and related FAQs.<\/p>\n<h5>What factors affect the longevity of a root canal?<\/h5>\n<p>Several factors influence how long a root canal-treated tooth will last, including timely placement of a permanent restoration (such as a crown), maintaining good oral hygiene, attending regular dental checkups, and avoiding habits like chewing ice or using teeth as tools. Teeth in the back of the mouth, which endure greater chewing forces, often benefit from full coverage crowns to protect against fracture. Smoking and untreated decay can also reduce long-term success.<\/p>\n<h5>\nDo you need a crown after a root canal?<\/h5>\n<p>Needing a crown after a root canal depends highly on the location of the tooth in the mouth-teeth towards the back of the mouth like molars and premolars are needed more for chewing, and generally require crowns, where incisors or canines which aren&#8217;t needed for chewing don&#8217;t always require crowns.<\/p>\n\t\t\t\t\t<a role=\"heading\" aria-level=\"2\" tabindex=\"-1\"  id=\"fl-accordion--label-1\"><h3>Safety, Myths &amp; Systemic Health<\/h3><\/a>\n\t\t\t\t\t\t\t\t\t\t\t<button type=\"button\" id=\"fl-accordion--icon-1\" aria-expanded=\"false\" aria-controls=\"fl-accordion--panel-1\"><i>Expand<\/i><\/button>\n\t\t\t\t\t<h5>Do root canals cause cancer?<\/h5>\n<p>There is absolutely no evidence that a root canal can cause cancer. All claims that root canals cause cancer or other illnesses are complete myths.<\/p>\n<h5>Are root canals safe for long-term health?<\/h5>\n<p>Yes. Root canal treatment is a well-established, evidence-based procedure that has been safely performed for decades. By removing bacteria and infected tissue from inside the tooth, root canal treatment helps prevent the spread of infection and supports overall oral and systemic health. When properly restored and maintained, root canal-treated teeth function like other natural teeth.<\/p>\n<h5>Can root canals cause systemic disease?<\/h5>\n<p>There is no valid scientific evidence linking properly performed root canal treatment to systemic diseases. This misconception stems from outdated research conducted nearly a century ago before modern sterilization and imaging techniques existed. Contemporary studies show that eliminating dental infection through root canal treatment reduces overall inflammation in the body rather than causing illness.<\/p>\n<h5>\nAre root canals linked to heart disease?<\/h5>\n<p>No. Current scientific evidence does not support a link between root canal treatment and heart disease. Treating infection inside a tooth with a root canal can help reduce the body&#8217;s bacterial burden and support better overall health.<\/p>\n<h5>Where did the focal infection theory come from?<\/h5>\n<p>The focal infection theory originated in the early 1900s, when limited scientific methods led some researchers to incorrectly believe that root canal-treated teeth could cause systemic illness. The research supporting this theory has since been thoroughly discredited. Modern endodontic procedures are performed using advanced sterilization protocols, magnification and imaging technologies that effectively treat root canal infection and make root canal treatment safe and predictable.<\/p>\n\t\t\t\t\t<a role=\"heading\" aria-level=\"2\" tabindex=\"-1\"  id=\"fl-accordion--label-2\"><h3>Cost &amp; Treatment Alternatives<\/h3><\/a>\n\t\t\t\t\t\t\t\t\t\t\t<button type=\"button\" id=\"fl-accordion--icon-2\" aria-expanded=\"false\" aria-controls=\"fl-accordion--panel-2\"><i>Expand<\/i><\/button>\n\t\t\t\t\t<h5>How much will the root canal procedure cost?<\/h5>\nThe cost varies depending on how complex the problem is and which tooth is affected. Molars are more difficult to treat; the fee is usually more. Most dental insurance policies provide some coverage for endodontic treatment.<br \/>\nGenerally, endodontic treatment and restoration of the natural tooth are less expensive than the alternative of having the tooth extracted. An extracted tooth must be replaced with an implant or bridge to restore chewing function and prevent adjacent teeth from shifting. These procedures tend to cost more and take more appointments than endodontic treatment and appropriate restoration.\n<h5>Is a root canal covered by insurance?<\/h5>\n<p>Many dental insurance plans provide coverage for root canal treatment because it is considered a predictable procedure to eliminate infection and save a natural tooth. Coverage levels vary by plan, so it is important to review your individual benefits or contact your insurance provider. Your dental office can often help estimate out-of-pocket costs before treatment begins.<\/p>\n<h5>Is it better to have a root canal or extraction?<\/h5>\n<p>It is always better to maintain a healthy, natural tooth whenever possible, and root canals allow for just that. Extracting and then replacing a tooth results in more expensive treatments, more procedures, and could even impact neighboring teeth and supporting gums.<\/p>\n<h5>Is a dental implant better than a root canal?<\/h5>\n<p>Whenever possible, saving your natural tooth with a root canal is the preferred option. Natural teeth are designed to function in harmony with surrounding teeth and bone. While dental implants are a reliable replacement option when a tooth cannot be saved, they require surgery and additional healing time. Preserving your natural tooth with root canal treatment is typically less invasive, less expensive, and requires fewer appointments, while at the same time helping maintain your natural bite and jawbone structure.<\/p>\n\t\t\t\t\t<a role=\"heading\" aria-level=\"2\" tabindex=\"-1\"  id=\"fl-accordion--label-3\"><h3>Finding an Endodontist &amp; Professional Standards<\/h3><\/a>\n\t\t\t\t\t\t\t\t\t\t\t<button type=\"button\" id=\"fl-accordion--icon-3\" aria-expanded=\"false\" aria-controls=\"fl-accordion--panel-3\"><i>Expand<\/i><\/button>\n\t\t\t\t\t<h5>Can you refer me to an endodontist?<\/h5>\n<p>You can self-refer to an endodontist.
