A spray for the sting of mouth ulcers and oral sores
GUM AftaClear Spray is a hyaluronic-acid spray for mouth ulcers, canker sores and other minor oral lesions. Sprayed directly on the sore spot, it forms a protective film over the area, helping ease the discomfort of eating, drinking or talking while the mouth heals.
How it works
Spray directly onto the ulcer or sore area up to several times a day. Its small 15ml size is easy to carry for reapplying away from home.
Who it suits
- Anyone with a canker sore or minor mouth ulcer
- People who find eating or talking painful during a flare-up
- Denture wearers with sore spots from rubbing
- Anyone wanting a targeted spray rather than a full mouth rinse
Worth knowing before you buy: This spray addresses the discomfort of minor, already-present mouth ulcers; it does not prevent new ones from forming or treat any underlying cause.
