Implants that are buried under the gum tissue when placed are typically uncovered in a minor surgical procedure 2 months later in the lower jaw and 4 months later in the upper jaw. After the implants are uncovered, a small healing abutment will be placed on the implant. This healing abutment is left in place while the tissue heals and gets ready for the final crown. During this process, it is very important that the healing abutment be cleaned regularly by brushing and flossing. The tissue is susceptible to inflammation and infection during this time frame, and meticulous hygiene is very important.
