Question by Luna’s Mom: Can a sinus infection cause pain on a tooth that has a root canal?
I have a root canal on one of my molars (Got it about 8 years ago). It hurts sometimes, especially if I eat hard things or meat. It is hurting now while I have a sinus infection. Should I see a dentist? It has been 3 days of tooth pain.

The pain may indeed be coming from a sinus problem if the tooth is an upper back tooth. It may also be due to the root canal failing or if the tooth is fractured. You should see the dentist and let him do some testing and take an x-ray to see if he can determine the problem. Good luck.

I have a root canal treatment and I’ve waited for two months before putting the permanent seal and sometimes still hurt inside the tooth but the Dentist said its because of my sinusitis. Is it really normal that way?
