Is cleanliness of implants important?

Yes, it is extremely important. Considering implants are foreign objects in your mouth, you will appreciate how important their cleanliness is; at least as important as your own teeth, or maybe even more important. It may take a little practice to get used to cleaning them, but after all, it is not a difficult process. You just need to spare enough time to do it. Keep in mind that the most important factor for this procedure to be successful is regular mouth care.
