Hello doctor,

My daughter had a root canal yesterday and now has a strong post nasal drip that tastes like hypochlorite. Should I take her to the doctor?



Welcome to icliniq.com.

Typically, you will recover completely from a minor sinus issue like this within a few days, without any intervention from your dentist. However, if you are experiencing sinus issues that have worsened, or have not gone away after 2 to 4 days after your root canal or you believe you may be developing a sinus infection or you feel serious and significant pain and discomfort around your sinus or there is a metallic taste in your mouth, nose, or throat or you notice any kind of bleeding or pus in your nose or mucus, you should visit your dentist immediately.
