Post-op instructions: Root canal retreatment

Your lip, tongue, and cheek will stay numb for 2 to 4 hours. Don't eat on that side until feeling returns, and be careful with hot drinks.

Because we reopened a tooth that had already been treated, it may be more tender than a first-time root canal, and that can last a little longer. This is expected. Take ibuprofen and acetaminophen as directed, starting before the numbness wears off. Take any prescription exactly as written and finish antibiotics.

Your tooth has a temporary filling. Avoid chewing on that side and stay away from hard and sticky foods until your dentist places the permanent restoration. If we went through an existing crown, the crown is still in place and the opening is sealed with a temporary, so treat it gently. Book your final restoration with your general dentist within 2 to 4 weeks.

Soft foods for the first day or two, chewing on the other side. Avoid very hot, very crunchy, or sticky foods.

Normal routine the same or next day. Avoid smoking while you heal.

Brush and floss as usual; be gentle flossing next to the temporary.

Severe pain not controlled by medication, swelling, fever, a bad taste or pus, numbness past a full day, or a temporary that comes out.
