See the plaque
your brush missed.
Take one photo after you brush. Brushnumber finds leftover plaque tooth by tooth, scores your brushing from 0 to 100, and shows you exactly where to spend more time.
Scans run entirely on your phone. Your photos never leave your device.
Three steps to know your teeth
We learn about you, scan your smile, then give advice made for you.
Quick Questionnaire
Answer a few simple questions: sensitivity, bleeding gums, braces or aligners, and how you usually brush.
Snap a Photo
Follow the on-screen guide and take one photo. On-device AI finds each tooth and any plaque in seconds.
Score & Tips
Get your Brush Number, the areas to focus on, and care tips and products matched to you. Track your progress over time.
One number. Your whole brushing story.
The higher the score, the less plaque left behind. Check after you brush and watch it climb.
Good
Very little plaque detected. Your brushing coverage is excellent.
Fair
Minor plaque remains in a few areas. Focus a little more on the gumline.
Attention
Plaque is noticeable in several areas, especially between teeth and along the gumline.
Risk
Widespread buildup. With better technique and consistency, most people improve within days.
Plaque Control
Plaque is still present. Focus on brushing coverage and consistency first.
Gentle Care
Your cleaning is good, but your enamel and gums need extra gentle care.
Aesthetic
Your home care is strong. Time to think about whitening, polishing, or alignment.
Not just a score. It shows you where you missed.
Brushnumber scores three zones of your mouth separately, so your next brush is more targeted.
Gumline
Where teeth meet gums. The most overlooked spot, and the most important for gum health.
Between Teeth
Tight spaces your brush can't easily reach. Floss or a water flosser helps here.
Front Surfaces
The part of your smile everyone sees, and a common place for plaque to build up.
Illustration. Violet marks plaque, the same way a disclosing tablet would.

Questions you might have
Does Brushnumber replace my dentist?
No. Results are a guide for your daily brushing and are not a medical diagnosis. If you have pain, bleeding, or other symptoms, see a dentist, and keep up with regular checkups.
Do I need special equipment or disclosing tablets?
Nope. Just your phone. Follow the in-app guide and scan in good lighting for the best results.
How often should I scan?
At first, scan after every brush to find the spots you tend to miss. Once you've built the habit, a few times a week is enough to track your trend.
Does it work offline?
Yes. Scanning happens on your device, so you get your score without a connection. The questionnaire, recommendations, and history sync need internet.
How are products recommended?
We match your questionnaire answers and scan results (like gumline buildup or sensitivity) to your care needs, and every recommendation explains why.
