Zentflex Toothbrush overview | Teethstars.com

Brushing your tooth with an excessive amount of pressure could cause everlasting injury to the very important tooth construction. However how a lot pressure is an excessive amount of? The Zent flex toothbrush gives an elegantly easy resolution that ensures you at all times brush with precisely the suitable strain.

My preliminary impression of the concept behind the Zent Flex toothbrush was, “That’s sensible!”  There are comparable ideas in electrical toothbrushes that beep at you or flash a crimson gentle when the consumer makes use of an excessive amount of strain, however they don’t really cease the pressure.  We at all times advise sufferers to brush gently with a soft-bristled toothbrush.  In spite of everything, it takes little or no strain to take away dental plaque from the tooth.  However in my expertise, there are some individuals who simply can’t appear to minimize the strain they use.  The distinctive design of the click joint within the Zent Flex toothbrush could also be precisely what they want.

Tooth enamel is the toughest construction within the human physique, a lot more durable than bones.  It’s potential, albeit troublesome, to mechanically abrade (steadily put on away) enamel.  Enamel abrasion is just not our largest concern with poor brushing method, although.  

There are two severe penalties of an aggressive toothbrushing method: 1) gum recession, and a pair of) root abrasion.

Though poor brushing method is just not the first reason for gum recession, it’s actually a contributing consider many circumstances.  The gum tissues surrounding the tooth are comparatively delicate, so any inappropriate pressure could cause them to again away from that perceived harm.  Gum recession in itself is dangerous as a result of it’s a lack of attachment between the tooth and the underlying jawbone.  Gums which have receded don’t develop again.  Extreme gum recession can require gum grafting surgical procedure to restore the defects.

Within the consideration of poor brushing method, a recession is exceptionally dangerous as a result of it exposes the roots of the tooth, rising the chance for the second consequence of exhausting brushing: root abrasion.  Root abrasion is more likely than enamel abrasion as a result of the roots of tooth wouldn’t have a protecting enamel coating.  As a substitute, the roots are coated in a skinny layer of cementum, which may be very inclined to abrasion.  As soon as the cementum is gone, the underlying dentin (the most important element of tooth) is uncovered, resulting in a excessive danger for cavities and tooth sensitivity.  Like gums, cementum and dentin don’t regenerate on their very own.  If extreme abrasion happens, dental restorations could be essential to restore the defects.

The Zent Flex mechanism of “breaking” the joint at 150g of pressure is suitable primarily based on scientific analysis concerning the pressure required to take away dental plaque versus the pressure that damages dentin.  Analysis helps (and it simply is sensible) that rising pressure will enhance plaque removing.  That’s the entire level of brushing: to take away the sticky movie of plaque that accommodates disease-causing micro organism.  Sooner or later, although, that rising pressure will take away not solely the plaque but in addition the dentin to which it’s caught!

The brink of 150 grams of pressure can also be an accepted standardized quantity for Toothbrushing as the suitable quantity of strain.  We see this within the testing protocols that the American Dental Affiliation makes use of in its Relative Dentin Abrasivity (RDA) index.  They use 150g of pressure when testing the abrasion potential of varied sorts of toothpaste.

The explanation dentin is so important to this dialog is that it accommodates tiny pores, known as tubules, which create a communication between the oral atmosphere and the nerve inside every tooth.  Chemical or mechanical processes that open or widen these tubules will open that communication, which means you may be extra prone to really feel scorching, chilly, and candy sensations within the nerve.  This examine exhibits that utilizing a decrease pressure when brushing really helps to shrink these tiny pores, lowering sensitivity considerably.

[Side note: While sensitivity is a more common consequence of open dentinal tubules, we also need to worry about cavities.  The open pores in dentin increase the risk for bacterial contamination, and therefore increase the risk for cavities on these exposed root surfaces.]

After utilizing the comb myself, I used to be shocked to study that I brush too exhausting!  I’m a dentist!  In fact, I think about myself to be somebody with an ideal brushing method.  Throughout my first use of the Zentflex, it was exhausting to cease laughing at myself as a result of the click joint broke again and again.  I did really feel, as I brushed, that I may need been lacking areas, which brought on me to pay shut consideration to how completely I used to be masking the tooth.

The comb itself is snug and well-constructed.  The bristles really feel soft-to-medium-soft.  (Extra importantly, they felt a lot softer after the click joint broke at 150g of pressure.)  As I continued brushing, I seen that I used to be steadily altering my method to maintain the joint from breaking, so I believe this brush carries nice potential for coaching individuals within the applicable quantity of toothbrushing pressure.  If that is the one toothbrush you utilize, I imagine that over time you’ll develop a brushing method that might not trigger the joint to interrupt.


This toothbrush could be a beautiful instrument for anybody with delicate tooth, gum recession, root publicity, or just a naturally heavy brushing method.  I like to recommend it for these explicit individuals on account of its protecting talents and its coaching potential.  It additionally has the benefit of being a lot inexpensive than the typical electrical toothbrushes that promote the identical protecting features.
