teewai is an AI-powered dental analysis app that scores your smile's whiteness and health from a single photo. Snap a photo and teewai's AI extracts whiteness, shade, stain and dental-health signals; a deterministic engine then maps them to a VITA Classical shade, a 0-100 whiteness score, and a dental health score. You get an instant shade match, stain and plaque detection, a personalized research-backed whitening plan, and a journey tracker that shows your progress over time. Family plans include 5 members with 15 scans each per month, tracked individually. We use your Google account only to sign you in securely and create your profile — we never sell your data or use your photos to train AI models. Privacy Policy .
