Numbness & Immediate Aftercare
The anesthetic will leave your mouth numb for several hours. Avoid biting or eating until the numbness is completely gone to prevent accidentally injuring your cheek or tongue.
Once feeling returns, avoid chewing on the treated tooth — it may remain sensitive during healing.
Managing Pain
Some discomfort is expected, especially if there was a pre-existing infection. Recommended over-the-counter options:
- Ibuprofen (Advil/Motrin): 600 mg every 6-8 hours as needed
- Acetaminophen (Tylenol): 1,000 mg every 6 hours as needed
Start taking medication before the numbness fully fades and continue for 2-3 days. Pre-existing pain may take up to a week to fully subside. Contact us if pain becomes severe or unmanageable.
Managing Swelling
Mild swelling for several days is normal. Apply an ice pack wrapped in a cloth in 20-minutes-on / 20-minutes-off cycles. If swelling worsens or does not improve within a few days, call us.
Antibiotics
If antibiotics were prescribed, complete the full course exactly as directed — even if you feel better sooner. Stopping early can allow infection to return.
Eating Restrictions
You may eat once the numbness wears off, but avoid chewing with the treated tooth for several days. Stay away from sticky or chewy foods (candy, gum, caramel) that could dislodge your temporary filling.
Schedule Your Permanent Restoration
A root canal tooth requires a permanent crown to protect it from cracking. Do not delay this appointment — a temporary filling is not a long-term solution and bacteria can re-enter the tooth. Call 415-397-2804 to schedule promptly.
