What research shows
Snake fear is partly built in: infants show attentional bias to snake shapes before any experience of them, and the same is true in other primates. So the imagery arrives with a head start that has nothing to do with your week.

Dreaming about snakes
Threat that has not shown itself yet — the classic reading, and the one with the widest cultural agreement..
The psychological reading
Read less as danger than as something you already sense and have not named. The reaction in the dream carries the meaning: fleeing, freezing and killing the snake are three different answers to the same question.

Source: Nielsen & Zadra, 2003 — Typical Dreams Questionnaire, n=1181.
Figures come from the Typical Dreams Questionnaire, the standard instrument in dream research since 1958. Dream dictionaries almost never cite a number for how common a dream actually is — the research exists, it just does not get quoted.
The version matters
Different ways this dream shows up
Most dream dictionaries give one meaning for the whole symbol. In practice the specific version carries most of the information — losing every tooth and losing one tooth are not the same dream.
How to record a dream, why the feeling matters more than the content, and when recurring nightmares are worth a doctor rather than a dictionary — set out once on the main page.
Before you look anything up
How the dream felt matters more than what was in it. The same image can arrive as comfort or as threat, and that difference tells you more than any entry in a dictionary — including this one.
