Nearly half (42%) of US adults over 30 have gum disease — a leading cause of tooth loss. CDC, 2024. How does your routine compare?

1/5 How stiff are your toothbrush bristles?

Every answer links to its source.

Your dentist sees you twice a year. Your teeth need you twice a day.

Most of us were never really taught how to clean our teeth.

  • Toothbrush bristles can’t fully reach the spaces between teeth — that’s where plaque likes to stay.

  • A dental visit is 30 minutes. There’s no time to teach you a routine.

Is it for you?

It’s for you if…

  • Bad breath, sensitive teeth or bleeding gums bother you. Week 3 has a lesson on each one.
  • You want to avoid big dental bills down the road.
  • Conflicting advice online makes you anxious. You want one clear plan, backed by research.
  • You want hygiene tools that actually work — without testing every product yourself.
  • You want a better quality of life — for you and your family.

It’s not for you if…

  • ✕Something hurts right now. See a dentist first — no course replaces treatment. Then come back: the daily care after treatment is the part that’s up to you.
  • ✕You want a whiter smile by next week. We build a routine, not a quick fix.

How it works

Not another course you read and forget. A habit you keep.

Knowing what to do isn’t the same as doing it every night. Teesha is built around behaviour-change techniques, so what you read becomes what you do the same night.

  1. 1

    See your plaque

    On Day 3 a disclosing tablet and a “before” photo show exactly where your brush misses.

  2. 2

    One idea, right before you brush

    A 5-minute lesson before your evening ritual, with links to the research — then you use it right away.

  3. 3

    Your ritual grows step by step

    Each lesson adds one tool or step to your check-in — never a full overhaul at once.

  4. 4

    One tap to check it off

    Tick ✓ right in the email. Your streak keeps the habit visible.

Self-monitoring, goal setting and planning are among the techniques a systematic review linked to better oral hygiene habits — Newton & Asimakopoulou, J Clin Periodontol, 2015.

Your starter kit

Only tools that work.

No gadgets you don’t need. Every item on your Day 1 list is chosen with dentists and checked against the research — about $25 for the essentials. Everything is optional.

  • Disclosing tablets

    Chew one and plaque turns pink — so you can see exactly what your brush misses. Used on Day 3.

  • Soft toothbrush

    Gentle on gums. Soft bristles are what the ADA recommends.

  • Interdental brushes

    The must-have for between teeth, sized to your gaps.

  • End-tuft brush

    A single small tuft for the spots a regular brush skips.

  • Fluoride toothpaste

    The most-studied ingredient for preventing cavities.

A peek inside

This is what a lesson looks like.

Short enough to read right before you brush. One clear thing to do right after. And the study behind it, one tap away.

TeeshaDay 4 · 5-min read

The part your brush can’t reach

Your toothbrush cleans the front, back and top of each tooth. But where two teeth touch, bristles can’t get in — and that’s where plaque likes to stay.

Tonight: use an interdental brush in the right size for your gaps. Your sizing guide is attached.

Go gently. It should never hurt — if it does, ask your dentist.

The research: Worthington et al., Cochrane Review, 2019 — home use of interdental cleaning devices.
New step for tonight: clean between teeth

The science

Not one expert’s opinion. What the research shows.

Most advice online is one person’s take. Teesha is built with practicing dentists, and every recommendation in the course links to the study behind it — systematic reviews, clinical trials and guidelines from periodontal societies. No myths, no influencer hacks.

150+sources cited across 21 lessons

How we choose our sources

  1. 1Reviews before single studies. Cochrane reviews, meta-analyses and guidance from bodies like the ADA, CDC and NHS come first.
  2. 2Current evidence. We check for newer reviews and use the latest version.
  3. 3Checkable. Peer-reviewed research or official guidance, with a link you can open yourself.
  4. 4Not retracted. Every source is checked against retraction records.
  5. 5No overstating. If the researchers say “may”, so do we.

About 5 minutes for the lesson, plus your normal brushing time.

Is this a subscription?

No. You pay $19 once and keep access.
