Did you know that the flouoride application that the dentist applies in the office is 5x stronger as it is considered "Prescription Strength"?
Therefore, even if the dentist is "only" getting a good application of fluoride on the teeth and checking for decay betewen the teeth (where you & I generally wouldn't notice) they are getting more done than we may think.
I have worked in Pediatric Dentistry for 7 years and I am sad to say how many 3, 4 & 5 year olds come in with rampant decay. Many parents think that the "baby teeth" will just fall out anyway, so why bring them in, but then the child ends up in pain! We've had kids in our office with faces so swollen it would break your heart.
You, on the other hand, sound like you are doing an excellent job (better than most!) so I would say that you would be absolutely okay to stretch her recare out to 8 or 9months instead of 6months. Your dental office should understand due to your insurance situation.
Also, once your child is spitting her toothpaste out you can request a "take home fluoride gel" that is stronger than what you can buy in the stores, but not as stong as they administer at the dental office. It's better than Act or any of the rinses that you see OTC.
The one that we sell is called "Just for Kids" and it comes in Grape, Cotten Candy, Melon, Strawberry etc.
You just brush it on a few times a week and it's an added layer of protection to fight decay.
And by the way - for anyone that thinks baby teeth aren't necessary - TOTAL myth.
They are the place holders for the adult teeth. And the primay (baby) molars will be with your little ones until they are approximately 12 years old, so c'mon... just sayin'
