We highly recommend that you eat a healthy meal before your root canal procedure, as this will be difficult to do after your treatment is completed. However, if you opt for sedation dentistry, then you may have to fast for a certain amount of hours prior to your visit to avoid issues with nausea. You should also avoid alcohol and tobacco products before your appointment, as these can interfere with your recovery process. Many dentists will typically suggest taking over-the-counter pain relievers, such as ibuprofen, immediately before arriving at the dental office to minimize discomfort. Be sure to also get a good night’s rest the day before and after your appointment, which will help lower your nerves and boost your immune system.
