Does the resident flora of the mouth cause dental caries?

Yes! Dental caries is the result of bacteria settling onto teeth- particularly the pits and fissures on the top of teeth, under the contacts in between teeth, and at the gumline. The bacteria metabolize the foods you eat, and produce acid. At a ph below 5.5, the acid demineralizes your tooth structure. Demineralization is the earliest stage of dental caries.
Yes. Some of the bacteria normally present in the mouth form plaque and produce acid that dissolves the mineral in teeth causing caries.
Yes. Many bacteria are found in caries, the most common named is streptococcus mutans. But in answer to your question, the bacteria are from your mouth, but your mouth received the original bacteria from somewhere or someone. Probably your mom sharing food with you. Bacteria also are transmitted from kissing, etc.
Part. Takes bacteria (flora) converting sugars/starches into acid which etch holes in the teeth.

What is the cause of black, even white colored teeth with dental caries?

Decay. The bacteria causes decay which appears black in appearance. See a dentist asap to save the tooth.
Bacterial action. White spots associated with dental caries (cavities) are areas of the enamel that the bacteria have leached out the calcium. With calcium loss, you get a chalky-white appearance called decalcification. Black, brown and tan represent the decayed aspect of the cavity. Decalcification can be reversed, decay can only be removed.

Can there be some cure for dental caries without removing the affected teeth?

Yes. There are many procedure to save a tooth with carious lesions: root canal therapy, posts, crowns. These procedures can be performed only if there is enough solid tooth structure present and no periodontal disease. If there is not enough good tooth to warrant the time and expense of the above procedures, the tooth is deemed hopeless and extracted. $$$ can be better spent on an implant in that area.
Saving teeth. That's what dentists go to dental school for. To learn how to save teeth. From simple fillings to more involved endodontic, periodontal and restorative procedures. It's amazing what can be done nowadays. But we need our patient's cooperation in order to restore their teeth. At some point however, if the patient doesn't care or won't cooperate, or the tooth is hopeless, we can replace them.

Will brushing my teeth prevent the spreading of my dental caries?

Absolutely. Oral hygiene is the best way to prevent the spread of caries. Diets low in sticky foods and sugars will help as well. See your dentist regularly for professional cleanings to get those hard to reach spots.
Good hygiene helps. If by "spreading", you mean, transferring from one tooth to the next, then the answer is yes. When there is active dental decay present in your mouth, then the oral environment is not as healthy as it could be. The numbers of bacteria may increase putting other teeth at risk. Improving oral hygiene will definitely help slow the progression of untreated dental decay and prevent other cavities.
Tooth Brushing. Yes! Brushing can prevent the spread of dental caries. But brushing alone is not enough. You must also add flossing in between your teeth to be able to do a complete job. If you only brush, you are missing 35% of the plaque in your mouth. More than half of all cavities are found between teeth using x-rays. If you already have cavities you need them removed and teeth repaired.

Yes. Caries will cause varying types of pain depending on depth. Sensitivity to sweets, liquids, cold, hot and biting are the usual progression. Gingevitis will cause pain when the gums are brushed, when flossing, and when certain foods come it contact w the gums. And the pain is generalized usually.

What happens if oral candida (from the tongue) reaches brain through dental caries or other tooth problems?

Confusion. Would be among the symptoms but I have never heard of oral candida reaching the brain from the oral cavity. Bacterial infections from the six front upper teeth does occur but is rare.
Unlikely. That said see dentist immediately to treat any and all oral infections before they get out of hand.
