May be cast on yourself or another person or animal. The target becomes super squeaky clean. In a healthy way. No dried-out skin or brittle hair or anything like that. Will not clean teeth. For that, you’ll want the Oral Cleanse spell.
Cast on yourself or another person or animal. The target’s mouth, including tongue, teeth, gums, etc. becomes very clean and pleasant smelling/tasting. Won’t do dental work or fix cavities or anything. For that, you need Mouthwash of Dentistry.
Mouthwash of Dentistry
This is a dark green clear liquid that usually comes in a small bottle. It tastes about how you would expect mouthwash to taste — harsh and vaguely minty. When swished around the mouth for thirty seconds, this mouthwash will treat/cure any “diseases, disorders, and conditions of the oral cavity, commonly in the dentition as well as the oral mucosa, and of adjacent and related structures and tissues, particularly in associated maxillofacial area.” (Wikipedia) Cavities, missing teeth, toothaches, gum disease, oral cancer, you name it. It gets fixed. Where there were problems can now only be found healthy teeth and gums, and all that other stuff listed in the Wikipedia quote is healthy too.
Depending on the severity of the problem(s), and the patient’s own idiosyncratic physiology, sometimes multiple doses need to be swished to completely fix everything. But you have to wait at least 12 hours between applications.
