If you just finished a root canal, or if you have one coming up, the first thing you are probably looking for is relief. You have likely been dealing with a bad toothache for a while, and you are ready for the problem to be over. But as the numbness wears off after your visit, it is normal to wonder: "Is it supposed to feel like this? How long will this last?"
At The Endodontic Office, we know these treatments have a scary reputation. But the truth is, the procedure is done to stop pain, not cause it. Most of the bad stories people tell come from the tooth infection they had before they even got to the dentist.
Still, your body just went through a medical procedure, so you will have some questions. Let’s talk about the healing timeline, what is normal, and when you should give us a call at The Endodontic Office.
When you leave The Endodontic Office, you will still be numb for a few hours. Once that wears off, you will probably feel some tenderness in the area.
Think of a root canal like a small surgery for your tooth. We cleaned out the tiny spaces inside the root, and the tissue around the tooth—the bone and ligaments—will be a little irritated. Most patients say this feels like a dull ache or a "bruised" feeling rather than the sharp, stabbing pain they had before.
It is also very common for your jaw to feel stiff. You had to keep your mouth open for a while, and the spot where the numbing medicine was injected might be a bit sore. This usually goes away in a day or two.
Everyone heals at a different speed, but there is a general pattern we see here at The Endodontic Office.
The first three days are usually when you feel the most discomfort because the inflammation is at its peak. You might feel a sharp pinch if you accidentally bite down on that tooth. This is why we tell our patients to avoid chewing on that side until they get their permanent crown.
By the fourth day, you should notice a big drop in sensitivity. You might still "notice" the tooth is there, but you shouldn't need to take pain medicine as often. If the pain is still as bad on day five as it was on day one, give The Endodontic Office a call.
Within a week, most patients forget they even had work done. The area should feel calm and the gums shouldn't be sore anymore. At this point, you are just waiting for your follow-up visit to get your permanent tooth cover.
This is a question we hear a lot: "If you took the nerve out, why can I still feel it?"
It’s a great question. While the nerve inside the tooth is gone, the tooth is still sitting in a socket filled with nerves and blood vessels. Those are the tissues you are feeling. The ligaments holding the tooth in place are often swollen from the old infection, and they take a little time to calm down.
At The Endodontic Office, we compare it to pulling out a splinter. Even after the splinter is gone, your finger stays red and sore for a few days. Your tooth works the exact same way.
You don't have to just sit there and hurt. There are easy ways to feel better while you heal.
For most people, taking Ibuprofen (like Advil) and Acetaminophen (like Tylenol) works really well. Studies show that taking these two together can work better than stronger prescription pills. Just make sure to follow the directions from the team at The Endodontic Office.
If your gums feel irritated where the numbing shot was given, a warm salt water rinse can help. It keeps the spot clean and helps the swelling go down.
Stick to soft foods for the first few days. Things like smoothies, yogurt, mashed potatoes, or soup are best. Avoiding hard or crunchy foods keeps you from putting too much pressure on the tooth while it heals.
Q: Why does the tooth feel "different" to my tongue?
A: We usually put a temporary filling in the tooth after a root canal. This material is a bit rougher than your natural tooth and might wear down a little. As long as it hasn't fallen out completely, you are fine.
Q: What if my cheek is swelling?
A: A little soreness in the gums is normal, but if you see actual swelling in your face or a "pimple" on your gums, we need to know. If you get a fever or a bad taste in your mouth, call The Endodontic Office right away.
Q: Can I go back to work the same day?
A: Most people can! Unless you had a very strong sedative, you should be able to drive and go about your day. You might just want to avoid any big meetings where you have to talk a lot while you are still numb.
Q: Why does it hurt more when I lie down?
A: When you lie flat, more blood flows to your head. This can make a throbbing tooth feel stronger. Try using an extra pillow to keep your head propped up for the first night or two.
While some soreness is expected, there are a few "red flags" to look out for. Please call us if:
We are here to help you. We would much rather have you call us with a question than sit at home and worry. At The Endodontic Office, your comfort is our main goal.
The good news is that root canals work very well—over 95% of the time. Once the healing is done, that tooth can last for the rest of your life.
Just remember, the root canal is only the first part. You have to go back to your regular dentist to get a permanent crown. A tooth that has had a root canal is more brittle and can crack if it isn't protected. Don't skip that last step!
Some people wonder if they should see their regular dentist or an endodontist. An endodontist is a specialist who has two or three years of extra training just for saving teeth.
At The Endodontic Office, we use microscopes and advanced tools that help us see things that are hard to find with the naked eye. This helps us treat the infection more thoroughly, which usually means less pain and a faster recovery for you.
If you are in pain now or were told you need a root canal, don't wait. The longer an infection stays there, the harder it is to treat.
Give us a call at The Endodontic Office today. We will listen to you, explain how everything works, and help you get back to feeling like yourself. You don't have to live with a toothache.
