Interspace brushes such as TePe brushes have superceded dental floss, which is still  useful in tight contact points as recommended by your hygienist. You have variable sizes of spaces between the teeth, and you need to use appropriate sizes of TePes regularly to clean the teeth and gums in specific areas.

For about 10 % of the population who have chronic periodontal disease and have to spend a single period of around 10-15 minutes a day cleaning their teeth, this is the kind of brush you need. You need clear instruction by your dentist or hygienist on how and where to use the brush.
Occasional use of Corsodyl, again as advised from your dentist may help.
Also a referral to a specialist periodontist, a dentist who has had further specific training may be required to retain your natural teeth as long as possible.
