What to Expect in the First 48 Hours After a Root Canal
A root canal treats infection or inflammation inside a tooth and relieves the pain that often brings people in. Once the procedure is done, how you care for the tooth over the next two days plays a big part in how comfortable your recovery feels. This guide walks you through what is normal, what helps, and when to call your dentist.
The first few hours: numbness and sensitivity
Your mouth will likely still be numb for a few hours after treatment. During this time, avoid chewing on that side, sipping hot drinks, or testing the tooth with your tongue, since you will not have full feeling and could accidentally bite your cheek or tongue without noticing.
Once the numbness wears off, it is common to feel some tenderness around the tooth and gum. This happens because the tissues around the root have been worked on, even though the infection itself has been cleaned out. Mild soreness when biting down is also normal for a day or so.
Eating after a root canal
What and how you eat in the first 48 hours matters more than how long you wait to eat.
- Wait until numbness has fully gone before eating anything, to avoid injuring your cheek, lip or tongue.
- Choose soft foods for the first day, such as soups, mashed vegetables, yoghurt, rice, or scrambled eggs.
- Chew on the opposite side of your mouth as much as possible, especially if a temporary filling has been placed.
- Avoid very hot, very cold, hard, sticky or crunchy foods until the tenderness settles.
- Stay hydrated, but sip rather than gulp if the area still feels sensitive.
By the second day, most people can slowly reintroduce normal foods, as long as they avoid biting directly on the treated tooth with anything hard or chewy.
Managing pain and swelling
Some discomfort is expected and usually manageable with simple steps.
- Take any pain relief medicine your dentist has recommended, following the dose and timing given to you.
- A cold compress on the outside of the cheek for short periods can help with swelling or soreness on the first day.
- Keep your head slightly elevated while resting or sleeping, as this can reduce throbbing.
- Rinse gently with warm salt water a few times a day from the second day onward, which can soothe the gum tissue.
Pain should feel like it is improving, not getting worse, with each passing day. A level that stays the same or increases after 48 hours is worth a call to your dentist.
Oral hygiene during recovery
Keeping your mouth clean actually supports healing, so there is no need to avoid the area completely.
- Brush twice daily as usual, using gentle strokes near the treated tooth.
- Floss normally, being a little more careful around the temporary filling so you do not dislodge it.
- Avoid vigorous rinsing or spitting in the first few hours, as this can disturb the area.
Activity and rest
Most people can return to desk work or light daily activity the same day or the next, depending on how they feel. It is sensible to avoid strenuous exercise for 24 to 48 hours, since increased blood flow can sometimes add to throbbing or swelling. Getting a good night's sleep and avoiding alcohol or smoking in the first day or two also supports smoother healing.
When to contact your dentist
Most recoveries are straightforward, but it helps to know the signs that need attention.
| Symptom | What it usually means |
|---|---|
| Mild soreness improving daily | Normal healing, continue home care |
| Severe pain after 48 hours | May need an earlier review |
| Visible swelling on the face | Should be checked promptly |
| Temporary filling falls out | Contact the clinic to protect the tooth |
| Fever along with tooth pain | Needs prompt dental attention |
If you were advised to return for a follow-up visit or a permanent crown, keeping that appointment is important, as the tooth needs full protection to stay strong long term.

Frequently asked questions
Is it normal to feel pain after the numbness wears off?
Yes, mild to moderate soreness for a day or two is common as the tissue around the tooth settles. It should gradually ease rather than worsen. If pain increases sharply after 48 hours, contact your dentist.
Can I brush my teeth normally after a root canal?
Yes, you can brush and floss as usual, just be gentle around the treated tooth for the first day. Keeping the area clean actually helps healing.
When can I go back to a normal diet?
Most people can return to their regular diet within 2 to 3 days, once the numbness is gone and any soreness has settled. Until then, stick to softer foods on the treated side.
What if my temporary filling feels high or falls out?
A filling that feels too high can cause discomfort when biting, and this is easy to adjust. If it feels loose or falls out, call your clinic soon so the tooth can be protected before your next visit.
