It is important to realise that if implants are poorly cared for, they will develop a covering of hard and soft deposits (calculus and plaque) which is very similar to that found on neglected natural teeth. Untreated, these deposits can lead to gum disease which can ultimately lead to failure of the implant.
For most implant-supported teeth you will be able to clean around each supporting implant by brushing and flossing in just the same way that you would around natural teeth and tooth-supported bridges. In some areas special floss, interdental toothbrushes and other cleaning aids may be needed to maintain good oral hygiene. Cleaning is not at all difficult, provided that you do not have impaired use of your hands.
It is reasonable to expect some of the daily hygiene procedures to be a little more complex than around your original teeth - equally expect to spend more time than you may have done in the past if you wish to maintain optimum implant health.
Regular visits to the Hygienist for professional cleaning is strongly recommended and will help your implants hopefully last a lifetime.
