I've been taking my 4 year old in to the Dentist every 2 months lately, because she HATED going, and the dentist felt it would help her get used to it to go in more often, and they were also watching her 4 back molars because they had cavities. At her last appointment, she talked about the possibility of having to put her under to fill the 4 teeth :( Well, I really stepped up the xylitol gum, started using MI paste (without fluoride) 2x a day, spraying colloidal silver in her mouth 2x a day, as well as cell salts 1-2 times a day. We went in for an appointment yesterday, and the dentist was amazed! 3 of the teeth are now hard and the one on the bottom that had the biggest cavity has stabilized! I'm so happy! She still wants to eventually fill the bottom one, but said keep doing what you're doing, and we'll hold off until she's older and more comfortable at the Dentist! Heck, I'm hoping to heal the sucker so we don't have to fill it at all :)
Just thought I'd share!
