Introduction
Oral health is an essential component of overall well-being, significantly influencing individuals’ quality of life and general health. Despite advancements in conventional dental care, the prevalence of dental diseases such as caries, periodontal disorders, and oral infections remains high worldwide (Petersen et al., 2020). The growing interest in alternative and complementary approaches to healthcare has led to increased attention toward the use of medicinal plants in dental care. These natural remedies, rooted in traditional practices, have been recognized for their therapeutic properties, including antibacterial, anti-inflammatory, analgesic, and tissue regenerative effects (Shah et al., 2017).
Historically, plants such as clove, neem, and miswak have been used in traditional oral hygiene practices across diverse cultures (Salehi et al., 2019). These practices were not only effective in maintaining oral health but also provided insights into the bioactive compounds responsible for their efficacy. Modern research has confirmed the potential of these compounds in addressing specific dental issues, often with fewer side effects compared to synthetic treatments (Gupta et al., 2021).
One of the critical drivers for exploring plant-based treatments in dentistry is the growing resistance to antibiotics and the rising costs associated with conventional dental care. Medicinal plants offer a sustainable and cost-effective alternative, particularly for populations in low-resource settings (Saini et al., 2019). Furthermore, their incorporation into dental products such as toothpaste, mouthwashes, and gels has shown promising results in improving oral hygiene and managing conditions such as gingivitis and dental caries (Patil et al., 2020).
However, the widespread adoption of medicinal plants in dental care faces challenges, including the lack of standardized formulations, regulatory approvals, and robust clinical trials to validate their long-term efficacy and safety (Kumar et al., 2022). Addressing these gaps through rigorous research and development can pave the way for integrating medicinal plants into mainstream dental care, enhancing both prevention and treatment strategies.
This study aims to comprehensively assess the therapeutic potential of medicinal plants in dental care, focusing on their applications, effectiveness, and challenges. By consolidating existing evidence, this research seeks to provide a foundation for future studies and practical implementations of plant-based dental therapies.
Literature Review
Medicinal plants have been integral to traditional healthcare systems for centuries, particularly in addressing dental and oral health issues. Historically, plants like clove, neem, and miswak have been used for their therapeutic properties in oral hygiene practices across various cultures. The World Health Organization (WHO) has recognized the importance of traditional medicine and its potential role in primary healthcare, emphasizing the need for scientific validation and integration into modern medicine (WHO, 2018).
Traditional dental care relied heavily on medicinal plants due to their accessibility, affordability, and effectiveness. Miswak (Salvadora persica), a chewing stick used extensively in the Middle East, Africa, and Asia, has demonstrated antibacterial, antifungal, and anti-inflammatory properties (Almas et al., 2020). Similarly, clove (Syzygium aromaticum) has been utilized for its analgesic effects, particularly in alleviating toothaches, attributed to the active compound eugenol (Rao et al., 2017). Neem (Azadirachta indica) has also been widely used in India for its antimicrobial properties and its ability to prevent plaque formation (Sharma et al., 2020).
Contemporary studies have expanded the understanding of medicinal plants and their bioactive compounds in dental applications. For instance, Aloe vera has been shown to have anti-inflammatory and wound-healing properties, making it effective in treating oral ulcers and gingivitis (Hashemipour et al., 2019). Turmeric (Curcuma longa), rich in curcumin, has demonstrated significant anti-inflammatory and antimicrobial effects, particularly in managing periodontal diseases (Gupta et al., 2021). Tea tree oil, derived from Melaleuca alternifolia, has also been highlighted for its antibacterial properties against oral pathogens such as Streptococcus mutans (Gomes et al., 2018).
Several formulations incorporating these plants, such as herbal toothpaste, mouthwashes, and gels, have shown promising results. Clinical trials have indicated that herbal formulations can effectively reduce dental plaque, alleviate gingivitis, and prevent cavities with minimal side effects compared to conventional chemical-based products (Sharma et al., 2020).
Despite their potential, the integration of medicinal plants into mainstream dental care faces significant challenges. A major issue is the lack of standardization in the extraction, processing, and formulation of plant-based products (Kumar et al., 2022). Variability in bioactive compound concentrations due to geographic and environmental factors further complicates their therapeutic consistency (Saini et al., 2019). Additionally, robust clinical trials are limited, and many studies lack the methodological rigor required for regulatory approval.
While research has highlighted the potential of medicinal plants in dental care, several gaps remain. For example, most studies focus on in vitro or small-scale clinical trials, and there is a need for larger, long-term studies to establish safety and efficacy conclusively (Patil et al., 2020). Further exploration is also needed into novel delivery systems, such as nanoparticles and sustained-release formulations, to enhance the effectiveness of plant-based dental products (Gupta et al., 2021).
This review underscores the importance of bridging these gaps to fully realize the potential of medicinal plants in modern dentistry. By addressing challenges related to standardization, clinical validation, and regulatory frameworks, medicinal plants could significantly contribute to improving oral health outcomes globally (Abou et al., 2020).
Methodology
This study employed a systematic review approach to assess the therapeutic potential of medicinal plants in dental care. Relevant literature published between 2016 and 2024 was retrieved from electronic databases such as PubMed, Scopus, and Web of Science. Keywords including "medicinal plants," "dental care," "oral health," and "herbal dentistry" were used to identify pertinent studies. Inclusion criteria focused on articles that explored the efficacy, safety, and clinical applications of plant-based treatments for dental conditions like cavities, gingivitis, and periodontal diseases. Excluded were studies lacking experimental evidence, non-peer-reviewed publications, and those unrelated to oral health (Alqahtani et al., 2021).
The collected data were analyzed based on therapeutic properties, such as antibacterial, anti-inflammatory, and analgesic effects, along with clinical outcomes in human or animal models (Baskaran et al., 2021). Particular attention was given to the formulations (e.g., toothpaste, gels, or mouthwashes) and their effectiveness in preventing or managing dental diseases. Standard quality assessment tools, such as the PRISMA guidelines, were used to ensure methodological rigor and eliminate bias in study selection (Bhardwaj et al., 2019). Results were synthesized to provide a comprehensive understanding of medicinal plants’ potential in modern dentistry. The findings aim to inform further research and support the development of standardized, evidence-based plant-based dental therapies (Chaturvedi et al., 2018; Dhanani etal., 2019; Jayakumar et al., 2020).
Key findings
Medicinal plants have demonstrated significant potential in addressing dental and oral health challenges. The analysis of existing literature reveals their therapeutic properties, including antibacterial, anti-inflammatory, analgesic, and regenerative effects. These properties make medicinal plants valuable alternatives or complements to conventional dental care practices, particularly in managing common oral conditions such as dental caries, gingivitis, and periodontal diseases (Mehta et al., 2017; Rai M et al., 2018; Shukla et al., 2022).
The antibacterial activity of medicinal plants has been extensively studied, with compounds from clove, neem, turmeric, and tea tree oil showing strong inhibition of oral pathogens, such as Streptococcus mutans, Porphyromonas gingivalis, and Candida albicans. For instance, clove oil, rich in eugenol, has been effective in reducing bacterial loads in infected dental tissues. Similarly, neem has shown promise in reducing plaque and preventing bacterial colonization due to its azadirachtin content, which disrupts bacterial growth cycles. Aloe vera has been found to be particularly effective against fungal infections in addition to its antibacterial properties (Fig. 1).

The anti-inflammatory effects of medicinal plants also play a critical role in their therapeutic applications in dentistry. Curcumin, the active compound in turmeric, has demonstrated significant potential in reducing gingival inflammation and managing periodontal diseases. Its ability to inhibit inflammatory cytokines and oxidative stress markers has been validated in multiple clinical trials. Additionally, extracts from guava leaves and chamomile have been observed to reduce swelling and pain associated with oral mucosal conditions. These properties are particularly valuable in post-surgical dental care and for patients experiencing chronic gum inflammation.
The analgesic effects of medicinal plants, particularly clove oil, have been widely recognized in dental care. Eugenol, its active compound, provides rapid pain relief by acting on nerve endings, making it a common ingredient in dental anesthetics. Similarly, essential oils from peppermint and eucalyptus have shown promising results in reducing toothache and oral discomfort due to their menthol and cineole content, respectively.
Regenerative properties of certain medicinal plants have also been explored, with Aloe vera and chamomile showing potential in promoting the healing of oral wounds and ulcers. Aloe vera’s polysaccharides enhance tissue regeneration and reduce healing time, while chamomile’s flavonoids exhibit antimicrobial and anti-inflammatory effects that support wound recovery. These findings suggest that medicinal plants can be integrated into oral care products designed for individuals recovering from dental surgeries or trauma.
Clinical trials evaluating the efficacy of plant-based formulations, such as herbal toothpaste, mouthwashes, and gels, have shown encouraging results. Herbal toothpaste containing neem and clove extracts significantly reduced plaque levels and improved gum health compared to conventional fluoride toothpaste. Similarly, mouthwashes formulated with tea tree oil demonstrated strong antibacterial effects, reducing bacterial biofilm formation and preventing gingivitis. A clinical trial on turmeric-based gels for periodontal disease showed reduced pocket depths and inflammation, indicating their potential as an adjunct to standard treatments (Fig. 2).

Unlike synthetic pharmaceuticals, herbal products often lack stringent regulatory frameworks, leading to inconsistencies in product quality and labeling. Addressing these issues will require collaboration between researchers, manufacturers, and regulatory agencies to develop guidelines that ensure safety and efficacy while maintaining affordability and accessibility.
From an economic perspective, medicinal plants offer significant advantages, particularly for low-resource settings where access to conventional dental care may be limited. Herbal formulations, such as neem-based toothpaste or turmeric gels, are often more affordable than synthetic alternatives, making them a viable option for underserved populations. Additionally, the use of medicinal plants aligns with global sustainability goals, reducing reliance on synthetic chemicals and promoting environmentally friendly practices in healthcare.
Despite their potential, medicinal plants should not be viewed as replacements for conventional dental treatments but rather as complementary tools. Integrating plant-based therapies with existing practices can enhance overall dental care outcomes, particularly in prevention and early intervention. For example, incorporating herbal mouthwashes into daily oral hygiene routines can help reduce bacterial colonization and prevent plaque formation, while herbal gels can serve as adjuncts in the treatment of periodontal diseases.
Future research should focus on overcoming the identified barriers to maximize the potential of medicinal plants in dentistry. Innovations in delivery systems, such as nanoparticles and sustained-release formulations, could improve the bioavailability and efficacy of plant-based products. Moreover, interdisciplinary collaborations between botanists, pharmacologists, and dental researchers can accelerate the development of novel plant-derived therapies. Public education campaigns can also play a crucial role in increasing awareness and acceptance of medicinal plants in dental care.
In conclusion, medicinal plants hold immense promise for enhancing dental care by offering natural, effective, and sustainable alternatives to conventional treatments. Addressing challenges related to standardization, clinical validation, and regulatory approval is essential to unlock their full potential. By integrating these plant-based therapies into mainstream dental practices, healthcare providers can offer holistic, patient-centered care that improves oral health outcomes while promoting global sustainability.
