Wider potential of essential oils as an antimicrobial and anti-inflammatory agent is mainly responsible for their use in dental diseases. In the present review article, commonly used essential oils in dentistry have been explained systematically. The therapeutic efficacies of different essential oils in different dental diseases, viz. periodontitis, dental erosion, dental caries, dental pain, gingivitis, and plaque, have been discussed extensively. Finally, patents filed by various innovators on essential oils-based formulations and their applications in dental care have been well tabulated. In conclusion, essential oils have significant the potential for the management and treatment of various dental diseases. However, various preclinical and clinical studies supporting the safety and efficacy of essential oils must be performed for regulatory compliance and commercial exploitation of essential oil-based formulations.

Essential oils are raw, intensely reactive, condensed, water-insoluble fluids found in various plant parts. These are also known as aetherolea, ethereal oils, or volatile oils. They seem to be less viscous than oil, despite the word “oil,”and have more of a watery appearance [1]. Essential oils consist of a diverse combination of elements, often comprising thousands of essential oils. The unique percentage of all the ingredients yields the oil its special well- being and medicinal properties. Frequently known group of essential oil components including monoterpenes, diterpenes, sesquiterpenes, aldehydes, ketones, esters, alcohols, phenols, and oxides because of the health-boosting and purifying qualities which separate several elements, certain essential oils are antiseptic, and some of whom have anti-fungal, antibacterial, and anti- viral properties [2,3]. The presence of the essential oils varies from either colorless to further some color of the spectrum, and most of the color of the oil relates to its medicinal properties. For example, being blue, Chamomile Oil is generally useful for the aromatherapy massage undergoing “red hot” emotions since blue reflects its typical “cooling and soothing” action and stimulates both
