You have just been told you need root canal treatment, or maybe you have already had it done and you are sitting at home wondering whether what you are feeling is normal. Either way, the question is the same: how long is this going to take to settle down?
The honest answer is that most people feel back to normal within two to three days. That surprises patients, because root canal has a reputation for being a difficult recovery. In reality, the infection that led to the treatment is usually far more painful than the recovery from it.
Here is what to expect, broken down day by day and week by week, based on what we see in our clinic every week.
The First 24 Hours After Root Canal
This is the period most patients worry about, and it is usually more manageable than they expect.
The anaesthetic wears off (1 to 3 hours). You will start to feel sensation returning to your lip, cheek, and tongue. As it does, you may notice a dull ache around the treated tooth. This is normal. The nerve has been removed, but the tissues surrounding the root are still settling down after being worked on.
Take pain relief early. Do not wait until the pain builds. We recommend taking ibuprofen (400mg) and paracetamol (500mg to 1g) as soon as you feel the numbness fading. These two work well together because they target inflammation in different ways. Avoid aspirin, as it can promote bleeding around the treatment site.
Eating and drinking. Wait until the anaesthetic has fully worn off before eating, so you don't accidentally bite your cheek or tongue. When you do eat, stick to soft foods and chew on the opposite side. Soup, scrambled eggs, pasta, yoghurt. Nothing too hot, nothing too cold.
What it actually feels like. Patients tell us the sensation is similar to having had a deep filling. A low, bruised feeling around the tooth. Not sharp. Not throbbing. Just present. Most people manage comfortably with over-the-counter painkillers and do not need anything stronger.
Days 2 to 3: The Tenderness Settles
By the second day, the worst is typically behind you. The ache reduces noticeably, and you may only feel tenderness when you bite directly on the tooth.
Pain should be improving, not worsening. This is an important distinction. A root canal recovery follows a predictable downward curve. Each day should feel a bit better than the one before. If you notice the pain increasing after day two, or if swelling appears, that is worth a phone call to the practice.
You can return to work. Most patients go back to work on day two without any difficulty. Some go back the same day if the appointment was in the morning and they did not have sedation.
Keep taking pain relief if you need it. There is no prize for toughing it out. If ibuprofen and paracetamol are keeping you comfortable, continue for another day or two.
The First Week: Almost Back to Normal
By days four to seven, the treated tooth should feel close to normal. You might notice occasional sensitivity when chewing something hard, or a faint awareness that the tooth is "different." This is the surrounding ligament and bone adjusting, and it settles on its own.
Temporary filling care. After root canal, the tooth is sealed with a temporary filling or temporary crown. Be gentle with it. Avoid chewing gum, toffee, or anything that might pull it out. If the temporary filling does come loose or fall out, call us so we can replace it. Leaving the tooth open risks recontamination.
Brushing and flossing. You can brush normally from day one, but be gentle around the treated tooth for the first few days. Resume flossing as normal once any tenderness has gone.
The First Month: Crown and Full Recovery
The root canal itself heals relatively quickly, but the tooth is not fully restored until a permanent crown is placed. This is usually booked two to four weeks after the root canal.
Why you need a crown. A tooth that has had root canal treatment is more brittle than a healthy tooth because the blood supply to it has been removed. Without a crown, there is a real risk of the tooth fracturing. Dr Ankit Patel (GDC No. 259174), who carries out root canal treatment at our practice, always discusses the crown stage during your initial appointment so you know exactly what to expect and when.
Cost to plan for. Root canal treatment at Danbury Dental Care starts at £690 (or £850 to £950 with our endodontist for more complex cases). A crown starts from £790. We provide a full cost breakdown before treatment begins so there are no surprises.
Full recovery. Once the crown is fitted and you have had a few days to adjust to it, the tooth should feel and function like any other tooth in your mouth. Most patients forget which tooth was treated within a couple of months.

| First 2 to 3 hours | Anaesthetic wears off, mild ache begins |
| First 24 hours | Dull, bruised feeling around the tooth |
| Days 2 to 3 | Tenderness settling, most return to work |
| Days 4 to 7 | Close to normal, occasional sensitivity |
| Weeks 2 to 4 | Crown appointment, full restoration |
Normal Recovery vs Warning Signs
One thing we hear often is "how do I know if something is wrong?" It is a fair question, and it helps to know what to look out for.
| Normal recovery | Contact the practice |
|---|---|
| Mild, dull ache for 2 to 3 days | Pain increasing after day 3 |
| Slight tenderness when biting | Sharp or throbbing pain |
| Minor sensitivity to hot or cold | Swelling in the gum, cheek, or face |
| Feeling "different" for a week or so | Bad taste or discharge from the tooth |
| Occasional painkiller use | Painkillers not controlling the pain |
| Temporary filling feels slightly high | Temporary filling has fallen out |
If you notice any of the signs in the right column, get in touch with us. We would always rather check a tooth and find everything is fine than have you sit at home worrying. Our emergency dentist line is there for exactly these situations.
When to Call the Practice Urgently
Some signs need prompt attention. Call us straight away if you experience:
- Significant swelling that is getting worse, particularly if it affects your ability to swallow or open your mouth
- Fever alongside dental pain
- The temporary filling or crown has come out entirely, leaving the tooth exposed
- Severe pain that does not respond to ibuprofen and paracetamol taken together
- A visible lump or pimple on the gum near the treated tooth
These do not necessarily mean the treatment has failed. In many cases, a short course of antibiotics or a minor adjustment is all that is needed. But it is always better to act early.
How Sedation Affects Your Recovery
If you had IV sedation for your root canal, the tooth itself heals in exactly the same way. Sedation does not change the biology of the recovery at all.
What it does add is a few hours of grogginess on the day of treatment. You will need someone to drive you home, and you should plan to rest for the remainder of the day. No driving, no alcohol, no important decisions. By the following morning, the sedative will have cleared your system completely and you will just be dealing with the normal post-root-canal tenderness.
We see this regularly in our clinic: patients who choose sedation often report that their overall experience feels easier, because they were already relaxed when the anaesthetic was given and they have little memory of the procedure itself. The recovery is the same, but the anxiety around it tends to be lower.
Recovery from Root Canal vs Recovery from the Infection
Something that surprises patients is how much better they feel after root canal compared to how they felt before it.
If you came to us with an infected tooth (throbbing pain, sensitivity to heat, disturbed sleep), the root canal removes the source of that infection. Many patients notice the deep, pulsing pain disappear almost immediately after treatment. What replaces it is a much milder, localised tenderness that follows a clear downward trajectory.
In other words, the recovery from root canal is usually a step up from the pain you were already living with. That is an important distinction, because it means most patients feel relief rather than additional suffering.
Practical Tips for a Smooth Recovery
For a detailed guide to looking after your tooth, see our root canal aftercare article. In brief:
- Sleep with your head slightly elevated on the first night to reduce any swelling
- Avoid very hot or very cold foods for the first 48 hours
- Do not smoke for at least 48 hours (ideally longer), as smoking impairs healing
- Stay hydrated and eat nutritious food even if you do not feel like it
- Avoid chewing directly on the treated tooth until your permanent crown is in place
What If You Are Worried About Pain Before Treatment?
If you have not had the root canal yet and you are reading this to prepare, you may also want to read our guide on whether root canal is painful. The short version: modern root canal treatment, carried out under proper anaesthetic, should not be painful during the procedure. The recovery is manageable. And for patients who are particularly anxious, sedation makes the whole experience feel distant and calm.
