Buying Guide: Key Purchase Considerations
What to consider when choosing an oral gel treatment for cold sores or mouth sores:
- Active ingredient and strength: Benzocaine is common for numbness; menthol adds cooling. Check the percentage to match comfort and sensitivity.
- Application method: Touch-free applicators reduce contamination; pens offer portability; gels may provide longer protection but can feel sticky.
- Type of irritation: Cold sores, canker sores, braces-related pain, and denture irritation may respond differently to specific formulas.
- Skin compatibility and sensitivity: Some ingredients can irritate sensitive lips or mucosa. Consider alcohol-free and benzocaine-free options if needed.
- Duration of relief: Bioadhesive or protective coatings can extend relief; consider your daily activities and meals.
