You've just completed root canal treatment — the hard part is over. Most patients recover quickly when they follow a few straightforward guidelines in the first 24–72 hours. Knowing what to do (and what to avoid) makes a significant difference to your comfort and healing speed.
At Grandview Endodontics, we walk every patient through aftercare before they leave our offices in Chino, Fontana, and Moreno Valley. This article is your detailed reference to navigate recovery with confidence.
What to Expect in the First 24 Hours
As the local anesthetic wears off — usually within 2–4 hours — you may feel mild soreness or tenderness around the treated tooth. This is a normal inflammatory response. It is typically described as a dull ache or sensitivity when biting, similar to a bruised tooth.
For the vast majority of patients this is manageable with over-the-counter pain relievers such as ibuprofen or acetaminophen. Start taking them before the numbness fully wears off for best effect. If an antibiotic was prescribed, complete the full course even if you feel better quickly.
What to Do and What to Avoid
Do
- Take pain medication before the anesthesia wears off
- Eat soft foods for the first day or two (yogurt, soup, eggs)
- Continue brushing and flossing normally — gently near the treated area
- Apply an ice pack to your cheek for swelling (20 min on, 20 off)
- Schedule your follow-up crown appointment promptly
Avoid
- Chewing on the treated side until the crown is placed
- Hard, crunchy, or sticky foods that could dislodge the temporary filling
- Smoking — it slows tissue healing significantly
- Alcohol for 24 hours, especially with prescription medication
- Delaying the crown — an unprotected tooth can fracture
Good to know: Most root canal discomfort comes from the infection that was already present — not the treatment itself. Many patients feel significant relief from their toothache immediately after the procedure.
Long-Term Care for Your Treated Tooth
A root canal treated tooth can last a lifetime with proper care. The most important step is getting a permanent crown placed within 2–4 weeks of treatment. Without this protection, the tooth is vulnerable to fracture — particularly with molars that absorb heavy chewing forces.
- Brush twice daily with fluoride toothpaste and a soft-bristled brush
- Floss once daily, reaching beneath the gumline
- Visit your dentist for regular check-ups and cleanings
- Wear a night guard if you grind your teeth — crowns need protection from bruxism too

Contact Our TeamFrequently Asked Questions
Q: How long will I be sore after a root canal?
Most patients experience mild soreness for 2–3 days. Significant discomfort beyond 5 days is uncommon and worth reporting to our office.
Q: Can I go to work after a root canal?
Most patients return to desk work the same day. If your job involves strenuous physical labor, resting for a day is advisable.
Q: What happens if I delay getting the permanent crown?
The temporary filling is not designed for long-term use. Without a crown the tooth is vulnerable to fracture or reinfection — schedule your crown within 2–4 weeks.
