A properly done filling should be smooth and easy to clean. Floss should be able to glide without being shredded or torn.
If there is a problem with flossing, then the fillings should be examined for overhangs. Dental x-rays are very useful in visualizing the extent of the filling and checking for decay underneath.
If the filling has not been shaped properly, then it should be replaced to allow for proper hygiene. If plaque is allowed to accumulate around the filling because access for hygiene is not possible, then the filling material and the tooth can be damaged.
