Problems solved by technology
However, ammonia-containing compositions are difficult to store due to the high volatility of ammonia
Bottles and containers tend to lose ammonia during storage, especially at elevated temperatures, causing the remaining AgF solution to become unstable (leading to precipitation)

The present invention relates to an aqueous Silver Fluoride (AgF) containing solutions with pH 4.0-5.3.
Description
technical field [0001] The present invention relates to a silver fluoride solution for use in dental compositions. Background technique [0002] Products containing silver fluoride have been known for many years as a means of treating dental hard tissues. The solution is generally silver fluoride (AgF), silver nitrate (AgNO 3 ) or an aqueous solution of silver diamine fluoride (SDF). Specifically, these products are known to protect affected teeth by killing caries-associated bacteria and then promoting the remineralization of demineralized collagen. In addition, these products can be used to reduce tooth sensitivity by blocking the movement of fluid through the dentinal tubules. [0003] Products containing silver fluoride have the common disadvantage of changing the color of teeth affected by caries to a permanent black shade due to oxidation of the silver ions. The soft tissues of the mouth (gums, cheeks, lips, etc.) may also darken if in contact with solutions contai...
