I don't believe the changes in you tongue came from the wisdom tooth extraction. Most likely it is the body's response to certain medications, supplements, herbals, etc. (lichenoid reaction). The breath could also be from medications, medications/supplements causing dry mouth, changes in your diet, acid reflux, maybe even borderline to full diabetes. To minimize your symptoms, obviously hygiene (everyone's standard of hygiene is different from brushing once a month if at all to OCD overkill), plenty of hydration, and proper diet (keto diet equals keto breath).
