Yes — with Gumex Gum Paint you can usually rinse your mouth after 30 minutes, but it’s best to let the topical paint set and to follow the product label instructions since ingredients like tannic acid and phenol need time to adhere.

🏥 Aftercare

• Wait at least 30 minutes before rinsing so the paint can bind to the gum surface.
• When you do rinse, use gentle water (no vigorous swishing) and avoid brushing the treated area for that period.
• Avoid eating, drinking hot or acidic drinks, and smoking for 30–60 minutes to preserve the coating.
• If the paint flakes off, avoid reapplying without checking the product leaflet or a dentist.

⚠️ Warning signs

• Rapid swelling, hives, difficulty breathing, or throat tightness (possible allergic reaction).
• Severe burning, increasing pain, or new ulceration at the site.
• Persistent bleeding or worsening symptoms beyond 24–48 hours.

🩺 See a doctor

• See a dentist promptly if you have any warning signs, new severe pain, or if symptoms do not improve.
• For immediate severe reactions call emergency services (Apollo Emergency - 1066).
