Post‑Wisdom Tooth Removal: Swelling, Bad Taste & When to Worry

Mild‑moderate swelling peaks at 48–72 hours post‑extraction; a foul taste is not typical and suggests:

• Dry socket (alveolar osteitis): Lost clot → exposed bone; severe pain + bad taste/odor (day 3–5).
• Infection: Purulent discharge, fever, increasing swelling.
• Food debris: Trapped in socket; gentle salt‑water rinses help.
• Medication side effect: Metronidazole causes metallic taste.

Action: Contact your oral surgeon/dentist promptly for evaluation. Dry socket requires medicated dressing; infection needs antibiotics. Do not probe the socket.
