There are options of getting an implant done immediately while extracting the tooth but a prior detailed assessment is required whether or not you are a candidate for this kind of procedure. So your dentist
would be able to do that for you with the help of X-rays and CBCT scans. Plus have you considered saving the decayed tooth with an RCT? Coz if the tooth is not too much decayed and enough structure is left, we am even save the natural tooth and give you a crown on top. Consult your dentist for options. Good luck.
