Swollen cheek: You don't mention what tooth you had the root canal in, or how long ago. However, the root canal likely did not cause the swollen cheek. Sounds as if you may have had an abscess in the tooth, particularly if it was a back upper tooth, which caused the cheek swelling. If so, you may be on antibiotics, which generally take a few days to work. You may have swelling for around 10 days. See the dentist.

A few days: A swollen cheek is usually a sign of an infection. Antibiotic alone might reduce the swelling in a few days, but will not cure the problem permanently. Root canal treatment and antibiotics will more likely reduce the swelling in just 24-48 hrs. If not contact the treating dentist.

2-3 days: It will usually take 2-3 days to get resolution of a swollen cheek caused by an infected tooth.
