Ah, okay. I was under the impression (word of mouth is where I got it from) that it screwed with the development of the teeth, due to stuff that's actually -in- the milk proper.
Nope.
A study by Dr. Norman Tinanoff showed that breastmilk in itself does not give rise to cavities as much as was previously thought. Dr. Tinanoff believes that the milk proteins in breastmilk protect the enamel on the teeth, and that the antibacterial qualities in breastmilk stop the bacteria from using the lactose in breastmilk in the same way as regular sugar. This dentist also showed that 5 minutes of breastfeeding lowered the pH-level only slightly more than rinsing the mouth with a little water. The antibodies and antimicrobial propoerties in breastmilk were something I hadn't considered as well, but they make sense. Breastmilk can be kept out at room temperature for around 12 hours. Why? Because there are antimicrobial agents in the milk that keep bacteria from colonizing for quite a long time. So it makes sense that these agents would also prevent bacteria from developing in the mouth.

I knew that bottle/breast feeding for an overly extended period of time could cause teeth to grow in improperly, but I thought there was more to it.
Again, this is incorrect.

The Complete Book of Breastfeeding by Dr. Marvin S. Eiger
Suckling at the breast is good for your baby's tooth and jaw development. Babies at the breast use more muscles to get food than do those drinking from a bottle. The nursling has to draw much or all of the areola (the darker area around the nipple) into his mouth, move his jaws up and down, and squeeze with his tongue to extract milk. To accomplish this task, your baby has been endowed with jaw muscles relatively three times stronger than yours. As these muscles are strenuously exercised in suckling, their constant activity encourages well-formed jaws and straight, healthy teeth.
One factor accounting for many dental malformations that eventually send children to the orthodontist or the speech therapist is an abnormal feeding pattern, known as "tongue thrust." This is very common among bottle-fed babies, but almost nonexistent among the breastfed.
To understand why, we have to examine the mechanisms of feeding. As we explain in detail in the Box on page 107 in Chapter 6, the breastfed baby works her gums and lower jaw quite vigorously to get the milk, whereas bottle-fed babies don't have to exercise their jaws so energetically, since light sucking alone produces a rapid flow. In fact, the milk often flows so freely that the baby has to learn how to protect himself from an oversupply so that he won't choke. He pushes his tongue forward against the nipple holes to stem the flow to a level that he can easily handle. Many dentists believe that such a forward tongue thrust can result in mouth breathing, lip biting, gum disease, and a generally unattractive appearance.
Another factor contributes to breastfed children's healthy tooth and jaw development. Since they get more of the sucking that babies need, they're less likely to suck their thumbs. Bottle-fed babies have to stop sucking on the nipple as soon as the bottle is empty to avoid taking in air; your baby at the breast can continue in this blissful pastime until you or she decide she's been at the well long enough.
Of course, not all bottle-fed babies develop dental problems, and some breastfed babies do. Still, this is one more realm in which breastfeeding remains superior to bottle-feeding. There is a lot of misinformation out there about breastfeeding because for several decades in the 20th century, it ceased to be the norm and became regarded as something unseemly at best and abnormal (and therefore obviously harmful) at worst. Most of it just doesn't hold up to any sort of factual scrutiny.
ETA: I just want to clarify, though I am a big believer in breastfeeding, I'm not a "boob ****." Yes, I believe it has benefits that I want my son to have, but only for so long as I'm willing to do it. I don't believe people who don't want to breastfeed should have to, and I'm not going to look down on someone for making a different choice. But breastfeeding IS, in fact, the
biological norm for humans. As someone who has done a lot of research on the subject and who has studied biology, I feel an obligation to correct any misinformation I encounter.
