A root canal can save your natural tooth, but proper aftercare is essential for healing and preventing complications. Here’s what you need to know — from eating and driving to hygiene and long-term care.
Immediately After Your Root Canal
Right after the procedure, your mouth will still be numb. Avoid eating or drinking until the numbness wears off (usually in 2–4 hours) to prevent accidentally biting your tongue or cheek.
- Rest for the day; avoid intense activities.
- Don’t touch or poke the treated tooth.If sedation was used, arrange a ride home — don’t drive yourself.
- Mild discomfort or pressure is normal and can be managed with pain relief.

Can You Eat After a Root Canal?
Yes. But you should wait until the numbness completely wears off before eating.
After your root canal procedure, local anesthesia can keep your lips, tongue, and cheeks numb for a few hours. Eating too soon may lead to accidentally biting your soft tissue or putting pressure on the treated tooth.
Proper eating habits protect the treated area and promote healing, talk with your endodontist in Vancouver BC about the best diet after root canal therapy.
Time After Procedure: What’s Safe to Eat? What to Avoid
| Time After Procedure | What’s Safe to Eat | What to Avoid |
| 0–3 hours | Nothing — wait until numbness fades | All foods and drinks |
| 3–24 hours | Soft, cool foods (yogurt, mashed potatoes, smoothies) | Hot, crunchy, sticky foods |
| 1–3 days | Semi-soft foods (eggs, pasta, rice) | Hard foods that require chewing |
| After 3 days | Gradually return to your normal diet | Extremely tough or sticky foods |
Chew on the opposite side of your mouth and avoid biting directly on the treated tooth until your permanent restoration or crown is placed.
If discomfort persists beyond three days, contact Hemlock Dental in Vancouver to schedule a follow-up evaluation.
Can You Drive After a Root Canal?
It depends on the type of anesthesia or sedation used.
If only local anesthesia were administered, most patients could safely drive after a few hours once normal sensation returns. However, if you received oral sedation, you may experience drowsiness, delayed reaction time.
Operating Safety Guidelines:
- Avoid driving for at least 24 hours after sedation.
- Have a friend or family member drive you home from the clinic.
- Refrain from operating heavy machinery or making critical decisions during this period.
Every patient responds differently to medication, so it’s best to confirm with your dentist before driving yourself home.
Can You Smoke After a Root Canal?
No smoking can significantly delay your healing process.
Nicotine restricts blood flow and oxygen delivery to your gums and jawbone, slowing tissue repair and increasing your risk of infection or inflammation.
Definitive Reasons to Reject Smoking:
- It interferes with oxygen circulation, making healing slower.
- It increases the risk of reinfection or “dry socket.”
- It may cause persistent pain and swelling.
If you’re a regular smoker, avoid smoking for at least 48–72 hours after your root canal. Use nicotine patches or sugar-free gum as alternatives during recovery.
Protect your investment; your root canal treatment can last for decades if you follow proper aftercare.

Over the Next Few Days for root canal after care
As part of your root canal aftercare, it’s common to feel mild pain, swelling, or pressure for a few days. Follow these care tips to ease discomfort and protect your tooth.
- Take OTC pain relievers like ibuprofen (as advised by your dentist).
- Use a cold compress on your cheek to reduce swelling
- Avoid hard or chewy foods until the area heals.
- Keep the area clean, but brush gently.
- Don’t skip meals — healing requires good nutrition.
*If your dental pain after root canal worsens or swelling increases, contact your dentist.
*If discomfort continues beyond a week, it’s important to check the root canal recovery time and how long results usually last
Oral Hygiene
You can and should maintain your oral hygiene routine — just go easy near the treated tooth.
- Brush with a soft-bristled brush twice daily.
- Floss gently and avoid snapping the floss near the treated tooth.
- Rinse your mouth with warm saltwater to soothe the area (½ tsp salt in 1 cup water).
- Avoid alcohol-based mouthwash during the first few days.
Keeping your mouth clean helps prevent reinfection.
Long-Term Aftercare and Crowns
After healing, a permanent restoration is often necessary.
- Most back teeth will need a dental crown to protect against cracks and restore function.
- Front teeth may need only a filling, depending on their condition.
- Avoid chewing ice, hard candy, or anything that might damage the restored tooth.
If left uncrowned, treated teeth—especially molars—can fracture or fail over time. When you do root canal without crown, your teeth are very vulnerable.
