Enhancing a Preventive Dental Care App with Optimized UX/UI

Product Type: Mobile App for Preventive Dental Care
Target User: Patients (Primary), Dentists (Secondary)
Core Functionality: Empowering patients to track and manage their oral health through digital checkups, automation powered risk assessments, and self-care recommendations, while providing dentists with insights for preventive care.

Background

This case study is a demonstrative project showcasing the UX methodologies and problem-solving approaches I have applied in real-world healthcare applications. While inspired by industry best practices, this example reflects the user-centered design strategies I have successfully implemented in similar projects.

Preventive healthcare is key to reducing long-term medical costs and improving overall well-being. Many individuals neglect early signs of dental issues due to lack of awareness, leading to expensive treatments and poor oral health outcomes.

As a Senior UX/UI Product Designer, I worked on developing a digital dental health platform that helps patients monitor their oral health, receive AI-driven risk assessments, and adopt preventive habits, while ensuring dentists have access to patient-generated data for better decision-making. This case study showcases the research-driven, user-centered design process I used to create an intuitive and engaging experience that aligns with CARE’s mission of preventive digital healthcare.

Problem Statement

Patients often ignore early dental symptoms due to lack of awareness, leading to:

  • Late-stage diagnosis of dental issues (e.g., cavities, gum disease).
  • High treatment costs due to delayed intervention.
  • Low adherence to oral hygiene habits.
  • Lack of easy access to professional advice for preventive care.

 

Goal: Design a mobile platform that enables preventive dental care through self-monitoring, habit tracking, AI-driven risk assessments, and easy access to expert recommendations while ensuring a seamless experience for both patients and dentists.

Research & Discovery Phase

User interview

Through in-depth patient interviews, we uncovered a significant gap in awareness about preventive dental care. Many patients assumed they only needed to see a dentist when in pain, highlighting the need for better education on early warning signs.

“I only go to the dentist when something hurts. I never thought about checking my oral health regularly—how would I even do that?”

Key insights
Patients don’t understand how their habits impact their long-term dental health.
Dentists need a way to track patients’ self-reported symptoms and adherence to care plans.

Surveys & Questionnaires

Distributed surveys to patients to quantify challenges in maintaining oral health habits, helping prioritize the most critical pain points in the app’s design. 

60% want a way to self-check their oral health before booking an appointment.

70% of patients only visit a dentist when experiencing pain.

UX Strategy & Definition

Persona

Created personas to represent both patients and dentists, ensuring the app addressed their specific goals and pain points for a user-centered design.

User Journey Mapping

By visualizing the user experience, I identified friction points like confusing automation results and improved the app’s flow to create a seamless experience.

Information Architecture

A clear information structure was designed to simplify navigation, ensuring patients and dentists could efficiently access relevant features.

Business Model Canvas

The business model canvas helped align design decisions with revenue strategies, including subscriptions, telehealth fees, and partnerships.

Key UX Considerations for Medical Applications

  • Trust & Transparency → Users must understand AI-generated health assessments.
  • Error Prevention → Clear step-by-step guidance to avoid misinterpretation.
  • Accessibility & Readability → WCAG-compliant color contrast & typography.
  • Data Security & Compliance → Adhering to HIPAA & GDPR for patient data protection.
  • Medical Terminology Simplification → Making dental health insights user-friendly.
  • Behavioral Change Design → Encouraging consistent oral care habits through habit-tracking and gamification.
  • Progressive Disclosure → Simplifying medical data presentation.

Wireframe & Prototype

The app offers a seamless experience for users to check their dental health through an automated-powered assessment, view their personalized dashboard with health insights and habit trackers, complete a questionnaire with adaptive questions, and easily book an appointment with a dentist using an intuitive calendar view.

The calendar provides a clear overview of scheduled patient visits, with options to manage, reschedule, or initiate telehealth consultations directly within the interface.
