Patient discussion about progression

Q. Is there a way stopping caries progress? I'm 17 and I've recently noticed I have chalky white spots on the back of two of my teeth at the bottom. I go to the dentist regularly (I have braces at the minute) and I'm assuming he's seen them but he hasn't mentioned them. I'm just curious as to weather caries are treatable? Is there anything my dentist can do to stop it progressing into something worse?

A. Caries starts by demineralization of the enamel. The enamel is the hardest material in our body. The bacteria gets the mineral out of it and it becomes weak. Start as white color and continues to a black unpleasant color as it progresses into the tooth. If you rinse your mouth often with fluoride and brush your teeth properly- it will stop the demineralization and the fluoride will take the place of other minerals in the enamel. This will stop the caries and the white spot will slowly becomes black. This is a good situation- it’ll be harder then before.

Q. Having chronic headaches, start in base of neck and progresses to migraine, worse when lying on stomach. Why? I have been having chronic headaches for the past 2 weeks. They start in the base of my neck and become migraines. They intensify when I lay on my stomach, blood rushes and they throb. Sometimes I can give myself relief by pressing firmly on my head or keeping my neck in a certain position. Just wondering if anyone knows what might be causing them.

A. Pinched nerve, bad posture is my problem anyway. I have a pinched nerve in my neck and my posture is horrible which causes me to get the worst headaches and they always start at the base of the neck and I always thought I had great posture (set up straight and all), but I was soooo wrong. Check with a Doctor and seek help from a Chiropractor if possible. They can do wonders. But for now, try lying on your back with a pillow or towel rolled up and placed under your neck only. It will support your neck and give it a nice crack too that helps a good deal too. That also helps keep the headaches away. Do you get sick to your stomach when the headaches come on?
