Toothbrush with Reactive Remineralization Composition
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for applying dental remineralization, whitening, or fluoridation compositions are cumbersome, difficult to use, and costly, often requiring cumbersome dispensing containers or complex two-part compositions that react outside the oral cavity.
Innovation Solution
A toothbrush design incorporating a remineralization, whitening, or fluoridating composition that remains inactive during storage and only activates when contacted with water or saliva, featuring a two-part or one-part composition integrated into the brush or handle, which reacts upon wetting to provide effective treatment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If two-part compositions are combined outside the oral cavity to form a paste, then remineralization treatment can be applied, but the method becomes cumbersome and difficult to use
Solution Approach 1:
The composition is divided into two separate parts (first composition and second composition) that are stored independently in the toothbrush handle. These parts are only mixed together when water or saliva is introduced during normal brushing, eliminating the need for separate mixing containers or complex application procedures while maintaining the therapeutic effectiveness of the combined composition.
Solution Approach 2:
The two compositions are pre-loaded into separate compartments within the toothbrush handle during manufacturing. This preliminary preparation allows the user to simply activate the compositions by introducing water or saliva during brushing, without needing to perform any complex preparation or mixing steps beforehand.
2Ease of manufacture
If compositions are incorporated in disposable toothbrushes, then cost is reduced, but the compositions must remain stable during storage and only activate during use
Solution Approach 1:
By dividing the composition into two stable parts that are stored separately, each component can remain chemically stable during storage without requiring complex stabilization mechanisms. The reactive combination only occurs when water or saliva is introduced during brushing, ensuring both storage stability and therapeutic effectiveness.
Solution Approach 2:
The compositions are designed to change their state or reactivity parameters only upon contact with water or saliva. During storage, they remain in a stable, inactive state. When activated by water or saliva introduction during brushing, they transform into the active therapeutic paste, achieving both storage stability and treatment effectiveness.
3Manufacturing precision
If complex dispensing containers are used for applying compositions, then precise application is achieved, but device complexity and cost increase
Solution Approach 1:
The dispensing function is merged with the toothbrush itself. The two compositions are stored in separate compartments within the handle, and mixing occurs automatically within the brush head when water or saliva is introduced during normal brushing. This integration eliminates the need for separate dispensing containers or complex pumping mechanisms while ensuring precise application to the teeth.
Solution Approach 2:
The system performs the mixing and dispensing functions automatically during normal brushing. When the user introduces water or saliva and brushes, the compositions are automatically mixed and applied to the teeth without requiring any additional manual intervention or complex control mechanisms.

Function Achieved in This Case
The solution provides a convenient, efficient, and cost-effective method for applying dental treatments by ensuring the composition remains stable until activation, enhancing user experience and reducing complexity and cost.
Implementation Method 1
the composition remains inactive during storage and only becomes active when contacted with water or saliva
Implementation Method 2
brushing the tooth with the toothbrush in order to remineralize, whiten, or fluoridate the teeth

AI summary
A toothbrush having brush means and a means to support the brush means; and a one or two part therapeutic tooth treatment composition which becomes activated when wet incorporated on the brush means or within the toothbrush means to support the brush means in a manner such that the composition remains inactive during storage and is only activated when contacted with water or saliva; and a method comprising brushing a tooth with the toothbrush so that the brush means become wet with saliva, optionally wetting the brush means with water immediately prior to brushing a tooth, and the composition becomes activated to form a therapeutic composition to provide remineralization, whitening, and/or fluoridation.
