A Sensor to Prevent Tooth Decay

UCH001_Sensor_Lookdev03_Yellow (2).png

Our Intraoral sensor monitors acid and transmits data to an app. The app alerts the user exactly when their teeth are at high risk of decay and suggests the appropriate dentist recommended product.


Users can then neutralize their acid at the earliest possible moment, before irreversible damage is caused. The dentist can access the patient's oral health trends through their existing practice management software to provide personalized prevention.

The U-Chu Acid Monitor will be the first objective data-driven solution to managing oral health and tooth decay. Dentists will no longer rely on expert opinions to develop preventative plans, but utilize personalized data to create plans tailored to each patient's unique needs. Patients won't have to guess when to use products, but will be informed immediately when a product is needed.

Fast facts:

  • Tooth decay affects 92% of American adults, and 60% of American youth

  • 24% of seniors age 64+ have no teeth left at all

  • The average American adult has 13 decayed or missing tooth surfaces 

  • Oral health affects systemic health:  infections from tooth decay can spread through your bloodstream to the rest of your body

  • People with diabetes, HIV/Aids, Sjogren's syndrome and those who use certain prescription drugs also experience a higher risk of tooth decay

  • High-risk patients see tens of thousands of dollars in dental costs

Cause of Caries Disease:

Tooth-Decay, or caries disease, is driven by acid imbalances in plaque and saliva. When oral pH drops below 5.5, teeth begin to demineralize; when pH rises above 5.5, teeth begin to remineralize. Patients who are known to be at high risk of caries experience longer acid-spikes than average due to their diet or low quantity/quality of saliva.


Currently, dentists assess caries risk by offering nutritional questionnaires and occasionally using a one-time pH strip. They give patients a suite of acid-neutralizing products (mouthwash, toothpaste, gums, mints/lozenges, sprays, etc.) to use as often as possible.

Unfortunately, this current standard is not effective and results in the alarming rates of caries we see today. Tooth decay is a time dependent process, and patients cannot prevent decay if they don't know when to use acid-neutralizing products.
