incisors, canines, pre-molars, molars, which are "cheek teeth" anatomy of tooth, gums, circulatory system and nervous system in mouth/teeth tooth/mouth conditions and problems — Preceding unsigned comment added by 188.8.131.52 (talk) 01:07, 27 September 2012 (UTC)
Tooth (plural teeth) are small, calcified, whitish structures found in the jaws Clearly this should be changed to "A tooth is a small, calcified, whitish structure. . . " because, it's you know, singular.
“Early fish such as the thelodonts had teeth for scales, suggesting that the origin of teeth was scales which were retained in the mouth.” - scales for teeth perhaps? Anihl (talk) 01:47, 27 February 2013 (UTC)
It's closer to accurate as is - early scales were heavily ossified, with dentine at the main support and a layer of almost-but-not-quite enamel. A subset of these were modified to become teeth. It's pretty poorly phrases as it is. I'll give it a quick edit, see if I cant improve it. HCA (talk) 16:28, 27 February 2013 (UTC)
Canines: In dogs, the teeth are less likely than humans to form dental cavities because of the very high pH of dog saliva, which prevents enamel from demineralizing
This seems inaccurate, despite it supposedly being sourced from a 1992 book. The pH level of sugar is neutral, but isn't it more accurate to state that dental cavities are a result of sugars instead of low, neutral or high pH level? 184.108.40.206 (talk) 14:15, 24 March 2014 (UTC)
Turns out it's right, at least according to the source I added. And the pH of sugar isn't the issue, it's the pH of the salivary fluid, which can either retard or enhance bacterial growth. HCA (talk) 16:58, 24 March 2014 (UTC)
