It is very difficult for me to answer this question without a consultation. However, depending on the type of problems you have with your teeth, would depend on whether you need or could have temporary solutions to any gaps.

It is possible that a temporary replacement tooth or bridge or denture can be made prior to the treatment, depending on the type of treatment desired and that would involve you visiting your dentist prior to the treatment appointment for impressions to make the temporary crown or bridge or denture.

I hope this answers your question.
