Dental infections are common conditions that affect oral health. These infections occur when bacteria invade dental tissue, causing pain, inflammation, and sensitivity.

They can be produced by :

    • Untreated cavities
    • Dental fractures
    • Plaque buildup

They can lead to the development of a dental infection. In addition to localized discomfort, such an infection can also cause:

    • Fever
    • swollen lymph nodes
    • It can even affect general health if not treated properly.

When tooth decay is left untreated, bacteria can penetrate the pulp, which is the central part of the tooth containing nerves and blood vessels. This can lead to an infection in the pulp, commonly referred to as necrotic or dead pulp. Alongside tooth decay, dental fractures also provide an entry point for bacteria, potentially resulting in an infection.

Another possible cause is periodontal disease, a bacterial infection in the gums that can spread to the tooth roots and affect surrounding tissues.

It is important to know that all essential oils must be diluted in other extracts or oils before use. Do not apply directly, since being highly concentrated, they can cause poisoning or allergies when in contact with the skin. For dental infections, the essential oil can be used by making a mouthwash (a few drops diluted in water) or via direct application (a few drops diluted in another oil; for example, coconut oil that can be ingested) with hyssop. Usually, the manufacturer indicates the need for dilution and by how much.

Under no conditions are essential oils to replace drug treatment or any other protocol indicated by the dentist; they are more effective as a complement to oral care to relieve minor symptoms, such as pain or evident inflammation.

Essential oils are classified according to their properties into different categories: floral, citrus, resin, stem, and leaf. Floral essential oils are highly recommended to combat stress, as they are cell regenerative and can also help relieve mental and emotional fatigue.

Heating the oil has an impact on its nutritional composition, causing the loss of essential fatty acids and vitamins. It also affects its sensory characteristics, such as texture, viscosity, aroma, and color. In addition, oxidation, polymerization, and hydrolysis reactions can occur during this process, generating toxic substances such as peroxides and free radicals, as described by Professor Cardenal Herrera of CEU University.

After being ingested, applied topically, or inhaled, every cell in our body experiences the effects of the essential oil in as little as 20 minutes. For this reason, many families choose aromatherapy as an alternative to non-natural options.
