Question 1

How does teewai analyze my teeth?

Accepted Answer

Snap a photo of your smile and teewai's vision and colorimetry engine estimates whiteness, VITA Classical shade, and visible surface staining or discoloration on a 0-100 scale.

Question 2

Is teewai a medical device?

Accepted Answer

No. teewai is a wellness companion. We strongly advise visiting your dentist for professional care.

Question 3

Does teewai work for families?

Accepted Answer

Yes. Family plans include up to 5 members with 15 scans each per month, tracked individually in a shared family dashboard.

Question 4

Does teewai use my photos to train AI?

Accepted Answer

No. teewai never uses your photos to train AI models and never sells your data.

Question 5

What is the difference between a quick scan and a full scan?

Accepted Answer

A quick scan uses one photo for a fast whiteness and shade estimate. A full scan captures five angles (front, upper, lower, left and right) for broader visual coverage across your smile, and costs 3 scan credits.

Question 6

How accurate is the VITA shade match?

Accepted Answer

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.

Question 7

Does teewai detect plaque, calculus and enamel wear?

Accepted Answer

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.

Question 8

Can teewai track how my diet stains my teeth?

Accepted Answer

Yes. Snap a photo of your meal and teewai identifies each item, then scores the chromogens, tannins and acids that cause extrinsic staining. Every scan rolls into a daily stain load so you can see exactly which foods and drinks are dimming your smile and get mitigation tips.
