I was shocked to learn that dental sealant exists. This simple procedure is very effective in preventing cavities, so once a kid has adult teeth they'll be protected into their 20s.
Yet, many people don't know to ask for this and can't afford the upfront cost (about $40 per tooth). Yet, unless your kid has fewer than 3 cavities as a teen it is the most cost effective and wellness promoting option.
It's wild to me this isn't a heavily subsidized and promoted procedure, but I guess dental care =/= healthcare...
