Dull throbbing pain in tooth after filling?

[perkypup6260]

I got a cavity filled a little over one week ago and my tooth has been in pain ever since. (top back right molar) I have had to take 400 mg of ibuprofen consistently in the morning and at night before bed because of the pain. The tooth was hurting a little before the filling was done and my dentist said that I had a hole in the tooth (I was totally unaware of it). He also showed me the x-ray and it was pretty close to the pulp of my tooth. I have to get a root canal don't I?

I wouldn't necessarily jump to the root canal conclusion. Sometimes pain can persist for a week or so because the tooth has been altered, particularly if the cavity was close to the root. Make an appointment with your dentist as soon as possible and explain your issue. It could be a simple fix.
