### output:

THANKS FOR YOUR QUERY, I HAVE GONE THROUGH YOUR QUESTION, The decayed front teeth can be restored with root canal treatment and capping if sufficient tooth structure and bone support is there. The missing teeth can be replaced with prosthesis...since you are telling you had cancer, and you are treated for it, you have not mentioned radiotherapy....if you have taken radiotherapy then it can cause reduced salivary flow which causes radiation induced caries....so consult an oral physician and get it treated as early as possible, because once the tooth structure is lost then it can't be restored. The Chat Doctor. .I hope my answer will help you.with regards
