These cute little guys - reminiscent extremely strong on bottle brushes in miniature ^^ "- are in this pack 8 times in different sizes represented (= 0.4 mm pink, orange 0.45 mm, 0.5 mm red 0.6 mm blue, yellow 0.7mm, 0.8mm green, purple 1.1mm, 1.3mm gray). Certainly it is better if you look to the dentist, which brushes are best suited for cleaning of his teeth , on the other hand has only one thing imho be respected and that goes also without a doctor. What is it? Only use the brushes that go without "use of force" and smoothly in the interdental spaces.
Course, if you naively thinks "Oh, bigger is always better, I'll take the 1,1mm brush and squeeze it until it stops in the canyon tooth", then yes, there will almost certainly be an abrasion (which by the way Wear / abrasion the tooth means) that describes Olaf Berk aka jonlar. This is true for all but Gell toothbrushes and not only for those of TePe ;-)
If you narrow interdental spaces have, starts best with the smallest brush. With different sized spaces, it may be that you will work with a variety of sizes. For me personally, I have found that I the sizes 0.4 and 0.45mm need. It's best to get yourself or the associated Interdentalgel to make it "better misses" and you have a antibacterial effect ;-) Important: As already written, but that really can not be too often say -> Never nienicht, never by force cut the brush into the spaces. Going on carefully. TePe it brings on its website well in a nutshell:
"The bristles should fill the gap, but should not touch the teeth of the wire core. Never try to force to force the brush into the spaces! Ask your dentist / -helferin to your right size."
The handling is easy: A dribble droplet Interdentalgel on the brush and carefully insert in the interdental spaces.
I find the use of the brush to be pleasant. The first three days were recorded for a specific problem tooth which tends often to inflammation (the Doof Kopp) to bleeding gums. Then it subsided and the area feels good. The brushes are specially in the molars in addition to the normal toothbrush used. Quite on the floss I can not refrain, however, as these special brushes only the spaces, but not clean the gum pockets.
Summary: A good package to determine firstonce which brush you need actually for his teeth, if you do not do the way to the dentist for. The course you have to decide what is best for you. I felt well enough informed by the video and application information from the Tepe site. As a complement to the normal tooth cleaning, the interdental brushes - for me - definitely a gain.
