Introduction

Dental diseases are among the most prevalent health problems worldwide. From tooth decay to gum infections, they affect individuals across all age groups, significantly impacting quality of life [1]. Despite advancements in dental care, poor oral hygiene, unhealthy lifestyle choices, and lack of awareness contribute to the increasing burden of oral health disorders [2]. Oral health is a fundamental component of general health and well-being. It affects one's ability to eat, speak, smile, and socialize without discomfort or embarrassment. However, dental diseases remain among the most common non-communicable diseases worldwide, with the World Health Organization (WHO) estimating that nearly 3.5 billion people are affected by oral conditions, particularly dental caries and periodontal diseases [3]. These conditions not only result in significant pain and infection but also impose heavy economic and societal burdens due to treatment costs and lost productivity. Dental diseases are often silent in their early stages, with symptoms becoming apparent only after significant damage has occurred [4]. Caries (tooth decay) and periodontal diseases (gum diseases) are the two most common dental conditions, both largely driven by bacterial biofilms (plaque) and modulated by individual behaviors such as oral hygiene practices, sugar intake, smoking, and frequency of dental visits [5]. Additionally, systemic factors like diabetes, immune function, and medication use can exacerbate oral disease processes. Beyond their localized impact, chronic dental diseases have been increasingly associated with systemic health issues including cardiovascular disease, diabetes mellitus, adverse pregnancy outcomes, and respiratory infections, highlighting the importance of maintaining oral health for overall health [6].

This paper delves into the most prevalent dental diseases, providing a clear overview of their causes, signs and symptoms, progression, and preventive measures [7]. It seeks to educate healthcare professionals, patients, and policymakers about the modifiable and non-modifiable risk factors that influence oral health. The emphasis on prevention is crucial, as most dental diseases are preventable through effective interventions at the individual, community, and health system levels [8]. Public health campaigns, community fluoridation programs, school-based dental education, and early screening initiatives are instrumental in reducing the incidence and severity of dental diseases. Additionally, advancements in dental technology and preventive care have opened new avenues for early intervention and long-term maintenance of oral health.

By increasing awareness and promoting evidence-based strategies, we can move toward a future where good oral health is accessible and achievable for all, reducing disparities and enhancing the quality of life for populations around the world.

Causes of dental diseases

Dental diseases encompass a wide range of conditions that affect the health of the oral cavity, including the teeth, gums, and supporting bone structures. Among the most prevalent dental diseases are dental caries (tooth decay), periodontal disease (gum disease), and oral infections such as abscesses. The understanding of these diseases is essential not only for dentists but also for the general public, as oral health is intricately linked to overall systemic health. The etiology of dental diseases is multifactorial. One of the most common causes is poor oral hygiene, which leads to the accumulation of plaque — a sticky film of bacteria that forms on teeth. If not removed through regular brushing and flossing, plaque hardens into tartar and contributes to the development of dental caries and gingivitis. Diet also plays a crucial role, with high sugar and acid consumption fueling the growth of cariogenic bacteria like Streptococcus mutans and Lactobacillus. These bacteria metabolize sugars to produce acids that erode tooth enamel.

Beyond hygiene and diet, genetic predisposition, hormonal changes, smoking, dry mouth (xerostomia), and certain medical conditions such as diabetes also contribute to dental disease development. Furthermore, limited access to dental care, low health literacy, and socioeconomic barriers exacerbate the risk, particularly in underserved populations.

Symptoms and diagnosis

The symptoms of dental diseases vary depending on the condition and its progression. In the early stages of dental caries, patients may notice white spots on teeth, indicating demineralization. As decay progresses, symptoms include toothache, sensitivity to hot or cold, and visible cavities. Gum disease initially presents as red, swollen, and bleeding gums, a condition known as gingivitis. If untreated, it may advance to periodontitis, characterized by receding gums, loose teeth, and bone loss [4]. Diagnosis typically involves clinical examination, dental X-rays, and periodontal probing to assess gum depth. Dentists may also utilize tools like fluorescence detection and fiber-optic transillumination for early cavity detection. Accurate diagnosis is critical for initiating timely and appropriate treatment [4].

Prevention strategies

Preventing dental diseases requires a comprehensive, multifaceted approach. The foundation of oral health lies in consistent oral hygiene practices, including twice-daily brushing with fluoride toothpaste, daily flossing, and regular dental checkups every six months. Professional dental cleanings help remove tartar that cannot be eliminated by brushing alone. Fluoride remains a cornerstone in caries prevention, available through toothpaste, mouth rinses, and community water fluoridation. Dental sealants are also effective, particularly in children, by protecting the grooves of molars from decay. Moreover, dietary modifications-such as reducing the intake of sugary snacks and acidic beverages-can significantly decrease disease risk. Public health efforts and educational campaigns play a vital role in promoting awareness, especially in communities with limited access to dental services. School-based programs, mobile dental clinics, and integration of oral health into primary care settings are promising strategies to bridge gaps in care [4].

In addition, increasing evidence suggests a link between oral health and systemic conditions such as cardiovascular disease, adverse pregnancy outcomes, and diabetes. This underlines the importance of recognizing oral health as a component of overall well-being and integrating dental care into broader healthcare delivery systems [6].

Conclusion

Dental diseases are largely preventable through routine care, timely treatment, and lifestyle changes. Raising awareness and ensuring access to affordable dental care are key steps toward reducing the global burden of oral health problems. By investing in oral hygiene and regular dental visits, individuals can safeguard not only their smiles but also their overall well-being. Understanding dental diseases-their causes, symptoms, and prevention-is critical for improving individual and public health outcomes. These conditions, though common, are largely preventable through proper hygiene, regular dental visits, and informed lifestyle choices. The relationship between oral and systemic health highlights the need for greater integration between dental and medical care. Effective prevention requires not only individual responsibility but also supportive public health infrastructure and access to affordable dental services. As research continues to shed light on the complex interactions between oral microbes, host response, and environmental factors, personalized and community-level interventions can be further refined to combat dental diseases effectively [4].

Ultimately, a holistic and proactive approach-emphasizing prevention, education, and equity is essential in mitigating the global burden of dental diseases and promoting lifelong oral health [4].
