After a dental procedure, perhaps the most widely known remedy for bruising and soreness is Arnica, which you can take in 12, 30, or 200 potency a few times on the day of the procedure.
Depending on other accompanying symptoms or irritations, it can be combined, if taken at least half an hour apart, with
- Belladonna (in case of throbbing pain or flushed face),
- Ruta (in case of jaw soreness, sore ligaments or soreteeth due to a heavy bite), and
- Pyrogenium (in case of infection, fever, sepsis).
In general, the more intense the symptoms, the more frequent the dosage. Increase the potency, however, only as the symptoms become more deep-seated on the psychological or emotional character of the person.
