Valuable baby teeth information: good dental hygiene schedule is the key element in preventing tooth rot, and for your child's health.
Parents need to take care of the babies' teeth for them. Babies drink mostly milk, and if they take their bottle with them to bed, it can cause a condition called tooth rot. To prevent this from happening the parent needs to start and maintain a good program of dental hygiene.To start off, let your baby observe you as you brush your teeth. You should not attempt this until your child is old enough to be able to spit out water when you give it to him, and drink it from a cup. Once he can do those things he is ready to begin the process. When you start brushing the baby's teeth, there don't necessarily have to be any teeth present, you can start early rubbing the baby's gums with the toothbrush and no toothpaste - but this is not really necessary since the child will learn later anyway.
When you choose a toothbrush for the baby make sure it is small, very soft, and has longer bristles in the front then at the back. This will ensure that even the hard to reach places will be reached in your baby's mouth. When you choose the toothpaste, choose any brand that has fluoride in it. You should use a low flouride level children's toothpaste. It isn't necessary to buy the expensive baby formulae since they contain the same things and in my experience the baby doesn't like the taste of the baby types of toothpaste.
