Overview of Common Oral Problems

Oral health is a critical component of overall health and wellbeing. It encompasses the health of the teeth, gums, and the entire oral-facial system that enables smiling, speaking, and chewing[1]. Common oral problems include a range of conditions that can significantly impact an individual’s quality of life, from causing discomfort and pain to affecting one’s ability to eat and speak, as well as their self-esteem[2].

Oral Cancer

Oral cancer is another significant concern, with oropharyngeal cancers linked to the Human Papillomavirus (HPV) being among the most serious conditions. While more research is needed to fully understand the connection between HPV and oral cancers, risk factors such as tobacco use and excessive alcohol consumption have been identified as critical in preventing these diseases[1]. Early detection of oral cancer significantly improves the chances of successful treatment and survival[1].

Dental Caries and Periodontitis

Among the most prevalent oral health issues worldwide are dental caries (tooth decay) and periodontitis (gum disease) [3]. Dental caries results from the destruction of tooth enamel due to acid produced by bacteria in dental plaque. It is the most common health condition globally, affecting people of all ages[4]. On the other hand, periodontitis is a serious gum infection that damages the soft tissue and, without treatment, can destroy the bone that supports the teeth, potentially leading to tooth loss[1][3]. Both conditions are largely preventable through regular dental care, including proper oral hygiene practices like brushing and flossing, and professional dental cleanings to remove plaque and tartar buildup. However, access to dental care remains a significant challenge, particularly in low- and middle-income countries, where treatment for oral health conditions is not commonly included in universal health coverage[4].

Impact of Oral Health on General Well-being

The importance of oral health goes beyond the mouth. Dental problems can have far-reaching effects on an individual’s overall health and well-being. For example, periodontal disease has been linked to other noncommunicable diseases (NCDs) such as cardiovascular disease, diabetes, and chronic respiratory disease due to shared risk factors like tobacco use, unhealthy diets, and poor hygiene[4]. Moreover, oral diseases disproportionately affect the poor and socially disadvantaged, highlighting the need for improved access to preventive care and treatment[4].

PreventionandGeneral Care

Preventing common oral problems involves a multifaceted approach that emphasizes good oral hygiene practices, regular dental check-ups, and the use of effective oral care products. Common oral health issues such as cavities, gum disease, and oral cancer can significantly impact an individual’s overall well-being, yet they are largely preventable with proper care[2][1].

Good Oral Hygiene Practices

Good oral hygiene is the cornerstone of preventing dental problems. Brushing teeth twice a day, flossing daily, and using mouthwash can significantly reduce the risk of oral health issues[5][6]. Brushing removes plaque, a sticky film of bacteria that forms on the teeth, which if not removed, can lead to tooth decay and gum disease. Flossing helps remove food particles and plaque from between the teeth and under the gumline, areas that a toothbrush can’t reach[7]. Using a mouthwash, especially one with antimicrobial properties, can further reduce bacteria in the mouth[8][9].

Choosing the Right Oral Care Products

The selection of oral care products can play a vital role in the prevention of dental problems. Hypochlorous acid (HOCl) has emerged as a promising antimicrobial agent that is effective against a wide range of pathogens, including those that cause oral diseases[10][3][8]. Studies have shown that mouthwashes containing slightly acidic hypochlorous acid can prevent oral diseases by reducing supragingival biofilm and gingival inflammation[3]. Furthermore, hypochlorous acid mouthwash has been found to be effective in reducing salivary bacteria, including Staphylococcus aureus, in patients with periodontal disease[8]. It is important to choose oral care products that are gentle and free of harmful chemicals. Products such as BRIOTECH Pure Hypochlorous Acid Oral Swish, which is alcohol-free, and free of other potentially harmful substances like peroxide, fluoride, and sulfates, offer a safe and effective option for daily oral care[9].

Regular Dental Check-ups

Regular visits to the dentist for check-ups and professional cleanings are crucial for maintaining oral health and preventing problems. During these visits, dentists can identify and treat issues in their early stages, before they become more serious and difficult to manage[2][5]. The American Dental Association estimates that around 100 million people in the United States do not see a dentist every year, underscoring the need for increased awareness and access to dental care[2].

Dietand Nutrition

A healthy diet plays a significant role in oral health. Consuming foods rich in vitamins and minerals, and limiting sugar intake can help prevent tooth decay and gum disease. A balanced diet supports the body’s immune system, making it more capable of fighting off infections that could lead to oral health issues[5][6].

Hypochlorous Acid: An Overview

Hypochlorous acid (HOCl) is a weak acid recognized for its potent antimicrobial properties, being notably more effective than traditional bleach solutions[11]. This substance plays a critical role in the disinfection processes, primarily due to its strong oxidizing capability which enables it to invade and disrupt the DNA and RNA of pathogens, effectively neutralizing them[12]. HOCl operates by attacking invading pathogens, compromising their cell walls and ultimately destroying the invaders, akin to an internal defense mechanism against harmful microorganisms[13].

Chemical Properties and Stability

HOCl has no electrical charge, distinguishing it from its dissociated form, the hypochlorite ion (OCl−), which carries a negative charge[14]. Its effectiveness as a disinfectant is influenced by several factors, including its concentration, the presence of organic materials, and exposure to certain environmental conditions. Organic materials can reduce the “shelf life” of hypochlorous acid by diminishing the amount of free available chlorine[15]. Additionally, HOCl’s stability is affected by UV light exposure and temperature; it is advisable to store it in opaque containers at room temperature to prevent degradation into hydrochloric acid and oxygen[15].

Role in Disinfection and Sanitation

Hypochlorous acid’s disinfecting power is attributed to its ability to function as a strong oxidizing agent. It effectively inactivates various viruses and bacteria, including those specific to laboratory rodents, when used in sufficient volume or over an extended reaction time[16]. Its mechanism involves the disruption of bacterial membrane integrity, protein degradation, and inhibition of protein synthesis, particularly in the early phases of phagocyte action[17]. Moreover, stabilized HOCl has been identified as the active ingredient in certain disinfectant agents, underscoring its significance in combatting pathogens by disrupting their oxidative phosphorylation pathways[12].
