Your diet is staining your teeth. Now you can see it.
Snap a photo of your meal and teewai identifies every item, then scores the chromogens, tannins and acids working against your smile. Each scan rolls into a daily stain load so you learn exactly which habits are dimming your shine.
Chromogens
Pigmented foods and drinks that bind colour to enamel.
Tannins
Plant compounds that help stains stick to the tooth surface.
Acids
Erosive items that roughen enamel so stains cling.

Inspired by a color
no screen can display
In vision science, olo is a hyper-saturated teal perceived only when researchers stimulate isolated M-cones in the human eye — beyond the gamut of any screen on earth. Our signature teal is a tribute to that optical precision.
Goals work. Feedback works. Together they work far better.
In a landmark study, Albert Bandura and Daniel Cervone found that people given a goal and regular feedback on their progress put in dramatically more effort than people given only one of the two. The mechanism, they showed, is self evaluative discrepancy. The gap between where you are and where you want to be is itself the engine. Knowing where you stand in relation to your goal is what keeps you going. It is the idea at the heart of Think Small by Owain Service and Rory Gallagher, and it is exactly how teewai is built.

A goal AND feedback
Effort increase observed in Bandura & Cervone (1983), Journal of Personality and Social Psychology. Figures are the study’s, not teewai’s. The self evaluative discrepancy mechanism is further developed in Bandura & Cervone (1986) and Locke & Latham (2002).

Real stories from people who let their smiles speak
DA
Damilare
Student · University of Ilorin
“Signed up for the family pack so my siblings and I could all track our smiles. My little sister went from B2 to A2 in a month and now she won't stop smiling. Worth every naira.”
TO
Prof. Oluyo Temitayo
Biomathematician · LAUTECH Ogbomoso
“As a researcher, I appreciate the rigor. teewai's deterministic engine and VITA shade matching are grounded in real dental science. It's not just a filter. It's a measurement.”
FO
Feranmi Ojebisi
Verified user
“I was skeptical about AI dental analysis but the stain detection was scarily accurate. It caught the coffee stains on my lower teeth that my dentist also flagged.”
FE
Feyisope
Verified user
“The before and after preview is addictive. I've been whitening for three weeks and watching my shade move from A3 toward A1 is genuinely motivating.”
GB
Gbemisola
Family plan member
“My kids think the gamification is a game. They fight over who has the higher smile score. Anything that makes them want to brush their teeth is a win.”
OD
Osunkoya David
Student · Covenant University
“As a Covenant University student, I don't have time for regular dentist visits. teewai fills that gap. I scan once a week and track everything from my phone.”

“The full mouth scan is impressive. Five angles, complete picture. My dentist was impressed I even had that data to show her.”

“I've tried every whitening app. teewai is the only one that gives me a real number I can track. The personalized plan actually tells me what to buy and how often to use it.”

Questions, answered
teewai uses AI vision to analyze your photo against the VITA shade guide, the dental industry standard. It assesses brightness, shade, and staining to produce a 0 to 100 whiteness score in seconds.
Absolutely. Your scans are tied to your account and encrypted. You can delete any scan or your entire history at any time. We never share your photos.
No. teewai is your everyday oral care partner, not a medical device. Always consult a dentist for clinical concerns.
If the image is blurry, poorly lit, or doesn’t show all your teeth (like the top arch), teewai will request a specific retake so your score is accurate.
You can pick a one-time scan pack or an Unlimited plan (weekly, monthly, or yearly). There are no surprise auto-charges — your plan stays active for the period you paid for, and you renew only when you want to.
A quick scan uses one photo for a fast whiteness and dental health score. A full scan captures five angles (front, upper, lower, left and right) for a complete picture of your whole mouth, and costs 3 scan credits.
teewai compares your teeth to the VITA Classical A1–D4 shade guide, the same standard dentists use. For the most precise color calibration, include a VITA shade tab or a plain white index card in the frame as a reference.
A single photo cannot replace a clinical exam. teewai acts as your everyday oral care partner by estimating visible surface staining, discoloration, and shade appearance — clinical conditions like plaque, calculus, enamel erosion, or caries require an in-person exam by your dentist.
Yes. Family plans cover up to 5 members who all scan from one shared pool of scans. Only family top-up packs add scans to the pool — any individual packs a member buys or is gifted stay personal to them. The family dashboard tracks everyone's whitening progress, MMR, and scan count side by side.
