This sounds more like a dental issue than an
HIV symptom, especially since you've had wisdom teeth pain before (suggesting a chronic problem like impaction or pericoronitis — inflammation around partially erupted wisdom teeth).
Common Causes (not HIV-related):
Leukoplakia or irritation: Thick white/grey patches from repeated rubbing, tobacco (if applicable), or poor oral hygiene. Often painless but can hurt if irritated.
Infection or debris: Food particles, plaque, or bacterial buildup in the gum flap around wisdom teeth can cause white spots, pain, and bad breath/taste.
Granulation tissue or healing: If there's any minor trauma/inflammation, white tissue can form as part of healing.
Oral thrush (candida): White patches that can be scraped off; more common in people with weakened immunity, dry mouth, or antibiotic use — but not specific to HIV, and rare in early stages anyway.
HIV Link? Unlikely here. Oral thrush can occur in advanced HIV (not acute), but your description (localized near wisdom teeth, with pre-existing pain) points to dental causes. ARS doesn't typically cause isolated oral spots like this.
