I have a young son that has had nothing but trouble with his teeth since he was two years old. I know this is largely my fault as it was the middle of summer and I used to send him to bed with a cup of Apple Juice. He has been to the dentist and had much work done, costing me a fortune. Is it worth it? The teeth with all the problems are still baby teeth that he will loose eventually. I have heard stories that rotting teeth can cause the teeth underneath to rot also. Is this a fact? Do I keep sending him to the dentist paying out money or wait it out till the baby teeth have fallen out? Help me please!
