Carbon dioxide.

Sorry I was wrong it is acctually Phosphoric acid, not Carbonic Acid

Soft drinks and teeth

"A large number of soft drinks are acidic and some may have a pH of 3.0 or even lower. [3] Drinking acidic drinks over a long period of time and continuous sipping can therefore erode the tooth enamel. Drinking through a straw is often advised by dentists as the drink is then swallowed from the back of the mouth and does not come into contact with the teeth. It has also been suggested that brushing teeth right after drinking soft drinks should be avoided as this can result in additional erosion to the teeth due to the presence of acid. [4]"

Soda pop and bone weakening
The active ingredient in most soda pop is phosphoric acid. The pH of most soda pop is 2.8, which is very acidic. As we discuss in detail in the body PH page, you want your diet to ALKALIZE your body, and ingesting a highly acidic drink like soda pop does the opposite and is very detrimental to your health. Phosphoric acid also leaches calcium from bones and is a major contributor to the rising increase in osteoporosis.
soda pop and osteoporosis

Animal studies show that phosphoric acid, a common ingredient in soda pop, can deplete bones of calcium.

And recent human studies suggest that girls who drink more soda pop are more prone to broken bones. The soft drink industry denies that soda plays a role in bone weakening.

Animal studies, mostly involving rats, point to consistent and clear bone loss with the use of soda pop drinks. But as scientists like to point out, rats and humans are not exactly the same.

Phosphorus, which occurs naturally in some foods and is used as an additive in many others, appears to promote the loss of calcium, thus weakening bones. With less calcium available, the bones become more porous and prone to fracture. There is growing concern that even a few cans of soda pop per day can be damaging when they are consumed during the critical bone-building years of adolescence and childhood.

What happens when these soda pop-drinking individuals become middle-aged adults and they end up with osteoporosis and obesity?

By that time, switching to water, fruit or vegetable juices may be too little too late.

It's not only the sugar, it is also (at least in some soft drinks) the fact that the drink is acidic itself. It appears that they actually add acid to drinks to kill bacteria, which gives a resulting pH in the 2.5 to 3.0 region (this is the same as vingear (acetic acid)).

I've actually varnished a tooth, leaving a small uncovered area and put it in a sealed container of coke. After a week the unvarnished area has gone soft.

However an acid can only have an influence on enamel erosion for as long as that acid is in contact with the enamel surface of teeth. Soft drinks normally have little contact with teeth when compared to other foods. Studies on dental erosion have shown it to be dependent on several different factors. This means that susceptibility in individuals varies according to behaviour, lifestyle, diet and oral hygiene practice.

It is the acidic additives that they put in colas but is saw a article that read "a variety of popular beverages over a period of 14 days, found that non-colas and canned iced tea were especially harmful. They contain flavor additives, such as malic, tartaric and other organic acids, which are more aggressive at eroding teeth. Root beer, which contains the least amount of flavor additives, was found to be the "safest soft drink to safeguard dental enamel."

sugar in soda is used by bacteria that mae acids that eat away at the enamel of teeth.
