PROBLEM TO BE SOLVED: To provide an oral hygiene material which contains fiber with ion exchanging ability to protect dental plaque being deposited on the teeth and to maintain a correct pH balance in the mouth. SOLUTION: This oral hygiene material contains at least fiber with ion exchanging ability and pH balancing ability. The oral hygiene material is of a sheet or forming body. The oral hygiene material has ability to absorb/remove protein which becomes a binder of dental plaque in the mouth. When a person consumes sugar, carbohydrate, protein, and increased organic acid decreases pH to 5 to 3, the pH balancing ability recovers pH 6 to 7 to prevent deashing and dental decay.
