A single tooth implant is cared for in the same way as your natural teeth i.e with proper tooth brushing
If the implant doesn’t flow smoothly to the crown on top i.e. it is at a bit of an angle, then dental tape or superfloss may be needed to clean under the overhanging crown margin. As with normal teeth, where there is a slightly larger gap, then interproximal brushes should be used
instead, or as well as floss which can of course become a little redundant in the larger space.
If you have an implant retained bridge, then you may need to get superfloss in there just as you would for a normal fixed-fixed bridge. (see above)
If you have an implant retained denture then it's important to take it out to clean the implants in your mouth; then clean the denture in the same way as you would clean a cobalt chrome denture.
Professional cleaning- the high glaze of the porcelain or polished gold surfaces tend not to collect plaque and calculus and so professional cleaning is often not required.
If there is calculus, plastic instruments should be used where possible and not the metal tipped ultra-sonic instruments and steel hand instruments used for routine scaling, which can potentially damage the titanium abutments. Often the abutments, ( the bit that connects the implant itself to the crown or visible tooth) are low enough to prevent any exposure of the titanium surface of the implant, so this problem does not arise.
