No, there’s no such thing as cap cleaning. You just have to maintain the oral hygiene properly, brush twice a day, floss regularly. Get a dental check up done every 6 months. The cap will have some space eventually, when the natural bone loss is there. So after 8-10 years, you’d have to get it changed. Depends on your condition. So if your food is getting lodged in that area where the cap is fixed, get the cap changed.
