At a glance
After a root canal, expect the tooth and gum to feel tender for a few days, especially when you bite. Avoid chewing hard or sticky food on that side until the tooth has its final restoration, and keep your crown appointment if one is planned. Call us if pain or swelling gets worse instead of better, or the temporary filling comes out.
What should I do after a root canal?
- Wait for the numbness to wear off (usually a few hours) before eating, so you don’t bite your cheek or tongue.
- Chew on the other side until the tooth is fully restored. A tooth that has had a root canal can be more brittle, and the temporary filling is not as strong as the final one.
- For soreness, follow the directions on the package or from your dentist. If we prescribe an antibiotic, take all of it as directed.
- Avoid sticky foods such as caramel and gum, which can pull out a temporary filling.
- Brush and floss as normal. When flossing next to a temporary, slide the floss out sideways instead of pulling it up.
- Keep your follow-up visit. Most back teeth need a crown to protect them after a root canal.
How long does root canal recovery take?
| Stage | What to expect | What to do |
|---|---|---|
| First 24 hours | Numbness for a few hours, then tenderness when biting | Soft foods, chew on the other side, pain relief as directed |
| Days 2–7 | Tenderness steadily fades; mild sensitivity to pressure is common | Keep chewing gently, protect the temporary, call if pain is getting worse |
| When it’s healed | The tooth feels normal to bite on; any leftover tenderness is gone | Final crown or filling placed; regular checkups and X-rays as advised |

Why does the crown visit matter?
A root canal clears out the infection or inflamed nerve, but it does not make the tooth stronger. Back teeth take heavy chewing forces, and without a crown they can crack. A crack below the gumline can mean the tooth has to be removed.
At our office, a crown takes two visits. The final crown is placed about 5 days after the first crown visit, and Saturday appointments are available. Our dental prices page lists the published crown price.
What is normal and what is not after a root canal?
| Usually normal | Call us |
|---|---|
| Tenderness when biting for a few days | Pain that gets worse after 2–3 days |
| A slightly rough feel from the temporary filling | The temporary filling falls out or feels loose |
| Mild soreness in the gum near the tooth | Swelling in the gum, cheek or face |
| Jaw stiffness from a long visit | Your bite feels high, or you have a fever |
When to call us
Call (832) 612-2831 if pain builds instead of fading, you notice swelling, the temporary filling comes out, your bite feels uneven, or you have a reaction to a medicine. We’re open Tuesday, Wednesday and Saturday, 9am–3pm. Outside office hours, go to the ER or call 911 for facial swelling that is spreading, trouble breathing or swallowing, a high fever, or bleeding that won’t slow down with firm pressure.
Frequently asked questions
Most people go back to work or school the same day or the next day. You may want a quiet afternoon if your jaw is tired.
Tenderness usually improves over a few days. If it is getting worse rather than better, call us so we can check your bite and the tooth.
Talk with us. Until the tooth is restored, chew on the other side and avoid hard foods. Waiting a long time raises the chance of the tooth cracking.
Usually not, because the nerve inside has been removed. Some feeling in the gum and ligament around the tooth is normal.
