The threat of toothlessness is rising fast. The World Health Organization (WHO) states that around 3.5 billion people worldwide suffer from oral diseases. 

In India, an alarming 95% of the population has dental caries. 

Globally, oral diseases now surpass mental disorders, heart disease, diabetes, respiratory illnesses, and even cancer in terms of burden.

This surge is driven by poor oral hygiene awareness, limited access to affordable care, high-sugar diets, and tobacco use. 

Socioeconomic disparities further deepen the crisis

Despite growing awareness, income, education, and access to healthcare still dictate who receives timely and quality dental care, especially in rural India. High treatment costs, lack of awareness, and limited infrastructure mean most people seek help only when problems become severe. Points out Dr. Karishma Tiwari, a senior public health dentist at Kamal Hospital in Ghaziabad, Uttar Pradesh, India, “Without investing in affordable, preventive care and community education, these inequalities will continue to drive the rural health crisis.”

Dangerous Myths and Delayed Action

Dr. Tiwari, highlights how oral health is often neglected: "Many believe cleaning weakens teeth or think it's okay to lose a few because we have 32. Such myths and delays are fuelling the problem.” 

She recommends professional cleaning every six to eight months to prevent long-term damage.

Children's Dental Health in Decline

Dr. Tiwari is particularly concerned about toddlers and teens. “Children today eat too much sugar and too little fiber. I see 2.5-year-olds with severe decay. Toddlers breastfed beyond 1.5 years are increasingly developing bottle and nursing caries,” she notes.

She urges parents not to ignore milk teeth and to train children to brush twice daily. “Spacing or overlapping in kids' teeth should be treated early," she adds. She also recommends that schools hold dental camps twice a year to encourage early intervention.

Proper Brushing Habits Start Early

Dr. Tiwari stresses the importance of developing good brushing habits early in life. She recommends the circular brushing method, also known as Fones' technique, as the most suitable for children. For kids under seven years of age, only a pea-sized amount of toothpaste should be used, and fluoridated toothpaste should be strictly avoided until the age of 36 months to prevent fluorosis. Toothbrushes, she says, should be replaced every three months or earlier if the bristles appear frayed. 

It is these small but essential practices that can go a long way in protecting children's teeth from long-term damage, she says.

Pregnancy and Oral Health

Oral care is crucial for adults, too. “Pregnant women should have dental checkups during and after pregnancy,” says Dr. Tiwari. “Hormonal changes can worsen gum problems, which may lead to preterm births or low birth weight. A postnatal dental cleaning can reduce inflammation caused during pregnancy.”

Oral Health Affects Overall Well-Being

Dr. Tiwari warns that dental plaque carries bacteria like Streptococcus mutans and Staphylococcus, which can enter the bloodstream and harm the heart. “Brushing twice daily with the right toothbrush and visiting the dentist every eight months is essential. Ignoring symptoms like pain or bleeding gums can lead to serious consequences,” she cautions.

Shrinking Jaw Sizes

Jaw sizes are shrinking these days, leading to overcrowding of teeth in children. This often results in uneven teeth and can be an early warning sign for parents, as it increases the risk of cavities, said Dr. Karishma. She also expressed concern about the growing incidence of gingivitis, gum swelling, and bleeding. "Parents should watch for signs of overcrowding and regularly ask their children about any tooth sensitivity," she advised. "Under no circumstances should they use sensitive toothpastes without consulting a dentist. Always seek professional guidance before choosing any toothpaste for kids."

Environmental and Climatic Changes Impact Oral Health

Environmental and climate changes are increasingly impacting oral health. “The widespread availability of sugar led to a surge in dental issues in the West. India was less affected then, but rising access to sugary foods is now causing similar problems, contributing not only to dental caries but also to conditions like diabetes and obesity.” She added. 

Dr. Karishma said that climate change affects oral health indirectly, mainly through nutrition. In some regions, limited access to healthy food leads to poor diets, which worsen oral issues like decay and gum disease. Rural India especially faces nutritional gaps, and with limited healthcare resources, oral health often gets sidelined.

To tackle this growing crisis, we need a holistic approach—combining oral health education with broader nutrition and public health efforts to reduce the impact of poor diets and environmental stressors on dental well-being.

New Technologies Coming to the Rescue

New technologies are rapidly transforming dental care, making it more accurate, accessible, and patient-friendly. AI-powered tools now help dentists detect cavities and gum disease early through X-ray analysis. Teledentistry has expanded access to care, especially in remote areas, by enabling virtual consultations. Dr. Karishma said, “Smart toothbrushes track brushing habits and guide users to improve their oral hygiene. 3D printing is revolutionizing dental prosthetics by creating custom crowns, aligners, and dentures quickly and affordably.”

Laser dentistry offers pain-free treatments for cavities and gum issues with faster healing times. Saliva-based diagnostics allow early detection of oral and systemic diseases without invasive tests.  She said that AR and VR are enhancing dental education and helping patients understand their treatment plans. Finally, eco-friendly dental products are promoting sustainability without compromising oral health. Together, these innovations are reshaping the future of dental care.

Though awareness is slowly increasing, more needs to be done. A combination of healthy diets, proper brushing habits, and timely checkups can stop this global oral health epidemic in its tracks.
