“With its tailored design, the Circum® interdental brush cleans as optimally when it is inserted into the interdental space as when it is pulled out of it. The fine bristles develop a cleaning effect that has never been known for any other interdental brush. The tailored Circum® interdental cleaning brush actually offers one double cleaning effect by also covering the lingual tooth sections of the interdental space. “

Dr. med. dent., MAS (Parodontology) Rino Burkhardt

“We have to provide the patient with suitable hygiene products that are easy to use but still enable effective plaque removal. The superiority of interdental brushes compared to other hygiene products is well documented. In terms of effectiveness, however, no difference could be found between conical and cylindrical interdental brushes. Only Circum® interdental brushes adapt to the anatomy of the tooth and gums and also clean in otherwise inaccessible places.»

Xylitol is a natural sugar substitute that is found in vegetables and fruits. Xylitol has a high anti-cariogenic (i.e. caries-reducing) effect, forms less acid and promotes remineralization. 6 grams of xylitol per day (i.e. 6 xylix100 chewing gums) offer effective protection against caries. The Xylix100 chewing gum is sweetened only with xylitol and is therefore also suitable for diabetics! A natural and practical protection against caries on the go!

Chronic gingivitis is the main risk factor for developing periodontitis. The development of the tailored Circum®interdental brushes from Top Caredent makes interdental care easier for patients and is a guarantee of significantly better plaque removal.
