Hi Enna,
The mouth has many salivary glands located in various areas. Some may be functioning better than others... sometimes a gland will develop a stone and not produce saliva, etc.
There are many medications that contribute to a reduction in saliva. Both prescription and OTC like antihistamines. Also some meds taken long term can reduce it.
Lack of saliva can contribute to periodontal disease, gum recession, tooth decay, decalcifications, weaken enamel, etc.
Teeth crack when they are decayed underneath an existing filling, or when they have a large restoration in them, or if you have a grinding or clenching habit.
Teeth seem to "dissolve" when they are severely compromised due to lack of enamel and/or vitality.

I did have a high fever before my tooth cracked in half, but no cavities that I know of.....any input? |
