Innovation

Imagine curing tooth sensitivity in just 10 minutes — no repeated dentist visits required. Thanks to Theranautilus, a Bengaluru-based startup born at IISc, this revolutionary solution is becoming a reality.

The journey began with Dr. Peddi Shanmukh Srinivas, a dentist specialising in endodontic microsurgery. While training in advanced root canal treatments, Srinivas encountered a frustrating challenge — some procedures required extreme precision that human hands simply couldn’t achieve.

He envisioned smaller, more precise instruments, but that idea seemed impossible without compromising dexterity. His search for a solution led him to Professor Ambarish Ghosh and his groundbreaking work on magnetic nanorobots.

Theranautilus uses tiny magnetic nanorobots, each nearly 1/1000th the thickness of a hair. These microscopic bots enter the tooth's pores, cluster together, and trigger a precise chemical reaction that rebuilds the damaged enamel layer inside the tooth.

The technology is designed for both clinical treatments and at-home use, with a toothbrush-like device ensuring accessibility for everyone.

What sets this innovation apart is its ability to generate heat on the nanobot’s surface, effectively killing bacteria without relying on harsh chemicals or antibiotics.

With faster results, the technique provides long-lasting relief from hypersensitivity, expected to last at least a year or more.

Theranautilus has successfully completed animal trials and is set to begin human clinical trials this year, with plans to launch its products within the next two years.

But the vision goes beyond dentistry—their ambitious goal is to extend nanobot technology to cancer treatment, starting with certain aggressive cancers.

As co-founder Professor Ambarish Ghosh puts it, "We’re starting with oral healthcare, but our ultimate mission is to transform medical science and save lives."

Dental sensitivity, also known as tooth sensitivity, is a common dental problem characterized by a sharp and temporary pain or discomfort experienced when consuming hot, cold, sweet, or acidic foods and drinks. It occurs when the protective layer of enamel on the teeth is worn down, exposing the underlying dentin and nerve endings. Dental sensitivity can be caused by various factors, including:

1. Tooth decay: Cavities or dental caries can cause tooth sensitivity as they progress and reach the inner layers of the tooth.

2. Gum recession: Receding gums expose the sensitive root surfaces, leading to sensitivity.

3. Enamel erosion: Acidic foods and drinks, as well as excessive brushing, can erode the enamel, exposing the dentin and causing sensitivity.

4. Teeth grinding: Frequent grinding or clenching of teeth can wear down the enamel, making the teeth more sensitive.

5. Cracked or fractured teeth: These can expose the sensitive inner layers of the tooth, leading to sensitivity.

6. Dental procedures: Teeth whitening, dental fillings, and other dental treatments can temporarily cause sensitivity.

To manage dental sensitivity, you can:

1. Use desensitizing toothpaste: These toothpastes contain compounds that help block the transmission of pain signals from the tooth surface to the nerve.

2. Avoid acidic foods and drinks: Limit your consumption of acidic foods and drinks, such as citrus fruits, soda, and vinegar-based products.

3. Use a soft toothbrush: Brush gently with a soft-bristled toothbrush to avoid further enamel erosion.

4. Practice good oral hygiene: Maintain a regular oral hygiene routine, including brushing twice a day and flossing daily, to prevent tooth decay and gum disease.

5. Limit teeth grinding: If you grind or clench your teeth, consult your dentist to get a custom mouthguard or splint to wear while sleeping.

6. Visit your dentist regularly: Regular dental check-ups can help identify and address any underlying causes of dental sensitivity.

If dental sensitivity persists or worsens, it is important to consult a dentist for a proper diagnosis and treatment.

A dental cavity, also known as tooth decay or dental caries, is a common dental problem that occurs when the hard outer surface of a tooth, called enamel, gets damaged and forms a hole. It is caused by the interaction of bacteria in the mouth and the sugars and carbohydrates from the food we consume.

There are different types of dental cavities based on their location on the tooth:

1. Pit and Fissure Cavities: These occur on the chewing surfaces of the back teeth where pits and grooves are present.

2. Smooth Surface Cavities: These form on the flat surfaces of the teeth, typically between teeth or on the sides.

3. Root Cavities: These develop on the tooth roots, which become exposed as the gums recede due to aging or gum disease.

Several factors contribute to the development of dental cavities:

1. Poor Oral Hygiene: Inadequate brushing and flossing allow bacteria to accumulate on the teeth, leading to the production of acids that erode the enamel.

2. High Sugar and Carbohydrate Diet: Consuming sugary and starchy foods promotes the growth of bacteria in the mouth, which produce acid that attacks the teeth.

3. Dry Mouth: Reduced saliva flow due to certain medications or medical conditions can increase the risk of cavities.

4. Acidic Foods and Drinks: Frequent consumption of acidic beverages like soda or citrus fruits can wear down the enamel and make teeth more susceptible to decay.

5. Genetics: Some individuals may have naturally weaker enamel or deeper grooves on their teeth, making them more prone to cavities.

It is important to maintain good oral hygiene practices, including regular brushing, flossing, and dental check-ups, to prevent dental cavities. Additionally, reducing sugar intake, consuming a balanced diet, and using fluoride toothpaste can help in cavity prevention.

Human teeth are specialized structures located in the mouth that are used for biting, chewing, and tearing food, as well as for speech and other oral functions. They are composed of different layers, including the outer layer called enamel, which is the hardest substance in the human body. The main types of human teeth are incisors, canines, premolars, and molars.

1. Incisors: There are four incisors in the front of the mouth, two in the upper jaw and two in the lower jaw. They have a thin, sharp edge and are used for cutting and biting food.

2. Canines: There are two canines on each side of the incisors, one in the upper jaw and one in the lower jaw. They have a pointed shape and are used for tearing and gripping food.

3. Premolars: There are eight premolars in total, four on each side of the mouth. They have a flat surface with cusps and are used for crushing and grinding food.

4. Molars: There are twelve molars in total, six in each jaw. They have a larger surface area and multiple cusps, making them ideal for grinding and chewing food.

Teeth are hard, calcified structures found in the mouths of humans and other mammals. They are used for biting, chewing, and tearing food, as well as for speech and other oral functions. In humans, there are four types of teeth: incisors, canines, premolars, and molars. Each type of tooth has a specific shape and function. Incisors are used for cutting and biting, canines are used for tearing, premolars are used for crushing and grinding, and molars are used for grinding and chewing. Humans typically have two sets of teeth in their lifetime: primary (baby) teeth, which are eventually replaced by permanent teeth.
