Reactivity is on a spectrum
Immune responses to saliva proteins vary widely. Large local reactions are usually not full allergies — but sudden facial swelling or breathing changes need urgent care.
Frequently Asked Questions
Is a huge welt an allergy?
Large local reactions can happen without systemic allergy. Lip swelling, hives everywhere, or breathing trouble are different — seek emergency care.
Can reactivity change over time?
Yes. Repeated exposure can sensitize or desensitize people. New dramatic changes deserve a clinician's input.
