What Not To Do After a Root Canal

Getting a root canal is no fun. But once it’s over, you’re on the road to recovery, right? Well, sort of. There are a few things you should avoid doing in the days after a root canal, or you could end up right back in the dentist’s chair.

Be careful with these things after a root canal:

  • Eating hard or crunchy foods: Chewing hard foods can put too much pressure on your teeth and irritate the treatment site.
  • Drinking hot beverages: Hot coffee, tea, or soup can cause pain and irritation after a root canal.
  • Drinking alcohol: Alcohol can cause dehydration, which can lead to dry sockets. This is a condition where the blood clot that forms around the tooth becomes dislodged, exposing the bone and nerves.
  • Smoking: Smoking increases your risk of dry sockets and can delay healing. It’s best to avoid smoking for at least 24 hours after the procedure.
  • Eating sugary beverages: Sugar can promote the growth of bacteria and lead to tooth decay.
  • Strenuous activity: Exercise and other strenuous activities can increase blood flow and lead to bleeding and swelling. It’s best to take it easy for the first day or two after a root canal.
  • Touching the treatment site: It’s important to leave the treatment site alone as it heals. Touching it can irritate the area and delay healing.
  • Using a straw: Sucking can put too much pressure on the tooth and cause pain.

Now that you know what to avoid after a root canal, you can focus on recovery. Be sure to follow your dentist’s instructions and take things easy for a few days.


A root canal can be a necessary but unpleasant procedure. Fortunately, recovery is usually relatively straightforward. You shouldn’t drink coffee after root canal treatment before the anesthesia wears off.

Be sure to avoid hot drinks until your tooth is fully healed. Stick to lukewarm or cold beverages for the first few days. After that, you can drink coffee as usual, but take care not to damage your tooth.
