In brief: Some possibilities..
Lip smacking can be the result of a variety of different issues.
It could nothing more than a behavioral habit, or it could represent an adaptive response to a new oral prosthetic device. It can also be a manifestation of neurological issues, such as dementia, parkinson's disease, or tardive dyskinesia. Especially if it is accompanied by other symptoms, it should be investigated by a doctor.
