For people with inflammation or infection in the roots of a tooth, root canal treatment can relieve pain and protect the tooth from further damage. The procedure itself is relatively straightforward and will take one to two appointments to complete. While root canal treatment is a simple, common procedure, it isn't completely pain-free—as with any procedure, you may feel some discomfort for several days afterward. It's important to follow the post-op instructions that your dentist provides you with. This is especially the case for people with a temporary filling or crown in place. These instructions will help you manage your pain and take care of your tooth. In this guide, we'll explain everything you need to know about proper post-op root canal care, so you can stay comfortable during the recovery process and heal correctly.

General Tips

If you try to eat before the numbness in your mouth fades, you might accidentally bite your cheek or tongue. For this reason, you'll want to avoid doing so immediately after your procedure. You should also avoid biting down on the treated tooth until it's been completely restored. To avoid infection, don't forget to brush and floss as normal.

You should also make sure to return to your dentist for a final crown once your root canal and follow-up appointments are complete. This crown will cover the tooth and keep it from breaking. You should schedule this appointment immediately after your final treatment.

How to Mitigate Pain

It's completely normal to experience slight discomfort in the days following your appointment, especially when you're chewing. This discomfort may include tenderness and mild soreness in your jaw. Luckily, these symptoms won't last forever. They'll normally subside within several days, but in rare situations, they can also persist for a week or two. Until they go away, you can control them by using the pain medication prescribed by your dentist or with over-the-counter pain medication such as Motrin or Advil. To reduce pain and swelling further, you can rinse up to three times a day using warm saltwater.

Of course, not all pain is normal. If you're experiencing any of the following symptoms, you should contact your dentist immediately:

  • Severe pain or pressure that lasts longer than a few days
  • Swelling inside or outside your mouth
  • An allergic reaction to the prescribed medication
  • An uneven bite
  • The temporary crown or filling falls out

How to Protect the Tooth

You want to make sure to protect your tooth after root canal treatment. If you don't follow the proper post-op root canal care guidelines, the temporary filling or crown could fall out, or the tooth could be otherwise damaged. To protect your tooth, you should take certain precautions when eating. These precautions include:

  • Avoiding sticky foods, such as gum, and hard foods, such as nuts
  • Chewing on the opposite side of your mouth

The short answer: they don’t have to be. Thanks to modern techniques and local anesthesia, root canal therapy is often no more uncomfortable than getting a filling. But let’s take a closer look at what to expect — and when pain might signal a problem. 🦷 What to Expect During a Root Canal I f you’ve been told you need a root canal, don’t panic. The procedure is done to remove infection from inside the tooth , relieve pain, and save the natural tooth. Most patients feel little to no pain during the procedure , especially when performed by an experienced dentist. We’ve been providing root canals in Riverview, FL since 1999, and patient comfort is always a top priority. 😬 What About After the Root Canal? Post-treatment discomfort is normal and usually follows a predictable pattern: Day 1–2: Mild soreness or sensitivity around the treated tooth Day 3–5: Pain may gradually increase, peaking around days 5–6 Week 2 and beyond: The pain should steadily decrease In some cases, mild discomfort can linger for up to 6–8 weeks — this is still within the range of normal healing. This pain is often due to inflammation in the surrounding tissues, not the tooth itself. As your body clears out the inflammation, the pain should resolve on its own. Medications common prescribed for pain are: Tylenol 3 Ibuprophen 800 ⚠️ When Pain Is a Sign of a Problem While some discomfort is normal, severe or persistent pain may mean something isn’t right . Two common complications include: Short Fill: The root canals weren’t filled all the way to the tip of the root Missed Canals: One or more canals were not treated during the procedure These issues can allow infection to persist and require further treatment. That’s why follow-up care and communication with your dentist are essential.

In some tooth extractions, particularly wisdom teeth, a small piece of the root (called a root tip or fragment) may break off. While this can sound alarming, it’s not always dangerous. When is it OK to leave a root tip? Small (2mm) , uninfected tips near sensitive areas (like nerves or sinuses) may be intentionally left in place if removal poses more risk than benefit. When should it be removed? If the root is large, infected, or causing pain or swelling , it should be extracted by a dentist or oral surgeon. Leftover root fragments can lead to infection, pain, or delayed healing if not properly managed.  What to do if you’re unsure: Ask your dentist for post-op X-rays. Seek a second opinion if you have ongoing discomfort or weren't informed about a retained root.

If a tooth is knocked out, it's a dental emergency requiring immediate action. First, try to put the tooth back in its socket, then seek emergency dental care as soon as possible, ideally within an hour. If you can't put it back, keep the tooth moist by placing it in milk or saliva, or a tooth-saving solution. Detailed Steps: Locate the tooth: If possible, find the tooth that was knocked out. Handle the tooth carefully: Pick up the tooth by the crown (the chewing surface), not the root. Rinse gently: If the tooth is dirty, rinse it briefly with water or milk, but avoid scrubbing or removing any tissue attached to the root. Reinsert if possible: If the tooth is still loose, gently try to put it back in its socket, ensuring the root-side is facing the gums. Keep the tooth moist: If you can't put it back in the socket, keep the tooth moist by placing it in milk, your saliva, or a tooth-saving solution. Seek emergency dental care: Go to your dentist or a nearby emergency dental clinic as soon as possible, ideally within an hour of the injury. The tooth will have to ridgedly fixated for several weeks 6-8 or more done with heavy wire bonded over several teeth.

A chipped tooth can be caused by stress cracking or just a sharp blow to the tooth. As long as it's minor like in this picture it can be fixed with composite. If it goes into the nerve chamber of the tooth it will require a root canal and crown. Chipped teeth have symptoms of increased temporary sensitivity to air, hot cold fluids, or any that's chewed into the area. It will be a sharp pain that quickly (within a second goes away). The reason for this is dentinal sensitivity. When the outer enamel layer is chipped off into the dentinal layer it exposes the open tubules of dentin that communicate with the nerve directly. Its important to get a chipped tooth repaired quickly because a slightly aggravated nerve in a healthy state can become irreversibly aggravated over time requiring root canal crown due to bacterial contamination of the tubules.
