Temporary Stain Repellent for Teeth Whitening Maintenance

Resolve Bottlenecks,
Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Teeth whitening products and procedures leave teeth dehydrated and more prone to staining, requiring users to abstain from pigmented foods and drinks, which is inconvenient and temporary, as susceptibility to staining can last for several days to weeks post-whitening.

Innovation Solution

A temporary stain repellent is applied to teeth before engaging in staining activities, forming a protective seal that prevents pigmented foods and drinks from staining the teeth, using materials like castor oil, liquid polyester, or titanium dioxide, applied via trays, brushes, or other applicators, to maintain the whiteness of teeth.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Illumination intensity

If teeth whitening products or procedures are used to whiten stained teeth, then the teeth become whiter, but the teeth become dehydrated and more porous, making them more prone to staining

Engineering Contradiction:

Improvewhiteness of teethVSAvoidsusceptibility to staining

Core Design Contradiction:

Illumination intensityVSObject-affected harmful factors

Solution Approach 1:

The patent applies a protective coating to teeth before staining activities occur. This preliminary action creates a barrier that prevents pigmented substances from contacting and staining the teeth, thereby maintaining the whitening effect without requiring abstention from pigmented foods and drinks.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The protective coating acts as an intermediary layer between the teeth surface and pigmented substances. This mediator prevents direct contact between staining agents and the porous tooth structure, allowing users to consume pigmented foods and drinks while maintaining white teeth.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Object-affected harmful factors

If users abstain from consuming pigmented food and drinks after whitening, then staining is prevented, but convenience and quality of life are reduced

Engineering Contradiction:

Improvestaining preventionVSAvoidconvenience of lifestyle

Core Design Contradiction:

Object-affected harmful factorsVSEase of operation

Solution Approach 1:

The protective coating serves as an intermediary that enables users to consume pigmented foods and drinks without staining. This eliminates the need for lifestyle restrictions while maintaining staining prevention, thereby resolving the contradiction between effective protection and convenience.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent employs a thin film coating that conforms to the tooth surface, providing continuous protection during eating and drinking activities. This flexible barrier allows normal consumption habits while preventing pigment deposition, thus maintaining both effectiveness and ease of use.

Inventive Principle:

Principle #30Flexible shells and thin films

3Illumination intensity

If teeth are left dehydrated and porous after whitening, then the whitening effect is achieved, but the teeth remain susceptible to staining for several days or weeks

Engineering Contradiction:

Improvewhitening effectVSAvoidduration of staining susceptibility

Core Design Contradiction:

Illumination intensityVSDuration of action of stationary object

Solution Approach 1:

By applying the protective coating immediately after whitening procedures, the patent addresses the vulnerable porous state of teeth before staining can occur. This preliminary protection extends the duration of whitening effectiveness by preventing re-staining during the period when teeth are most susceptible.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The protective coating provides more than just basic protection; it creates a comprehensive barrier that fully seals the porous tooth structure. This excessive action ensures complete prevention of pigment penetration, thereby extending the whitening effect beyond what would be achieved by simple surface drying alone.

Inventive Principle:

Principle #16Partial or excessive action

Applied Scientific Principles

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.

Function Achieved in This Case

The temporary stain repellent significantly reduces tooth staining by up to 99% during consumption of pigmented foods and drinks, allowing safe consumption while maintaining the whitening effect for an extended period without the need for frequent touch-ups.

Implementation Method 1

applying a temporary stain repellent to teeth subjected to anticipated teeth staining activities or pigment depositing activities immediately before said activities, thereby forming a protective seal over the teeth

AI summary

Methods, compositions, and products maintain white teeth or prolong the effects of teeth whitening by preventing staining of teeth via a temporary stain repellent. The temporary stain repellent can include a food-grade silicone compound configured to temporarily form a protective layer over teeth or fill the pores of the teeth before and during the consumption of pigmented foods and/or drinks post-teeth whitening.
