If the tooth has large enough decay that it can not be restored, it must be removed. How soon an extraction is needed would be hard for me to say, but I would recommend having the tooth removed sooner rather than later to prevent infection, tooth fracture and/or pain/discomfort. A bridge or dental implant would be recommend as replacement after having the tooth removed. I hope this helps! Click "save" under my name, if you'd like to ask me more questions in the future.
I had crown in 2008. I was getting foul swell when I flossed. Dentist tells me x ray shows decay in side crown. Now has to pull?
