<s>[INST] Is it better to wait to have permanat filling after root canal treatment till the preganancy is over? I m 23 weeks pregenant! I just had my root canal treatment done a week ago. [/INST] Hi Fiona, if your doctor is sure about the treatment given, he should give you the permanent filling only. Temporary filling as the name suggest is only for short time. If it gets dislodged again you will get the infection in that tooth. If you need any further treatment in the same tooth, we can remove that permanent filling also. So I suggest take safe and sound treatment by getting the permanent filling only. Thanks. </s>
