| Aug 23, 2013 at 4:37 | comment | added | Randy | I am unable to find the text I had read before, which was making the claim that diets deficient in calcium resulted in children's teeth decaying before eruption. All I can find on the matter is this cyberdentist.blogspot.com/2006/11/… which backs what you've already said. I am curious how calcium in our diets affects how resistant our teeth are to decay. And how phosphoric acid in soft drinks may remove calcium from the body and promote decay. | |

However they can undergo a process called resorption under some circumstances. Rosorption of teeth are by cells called odontoclasts. In xrays these partially resorbed teeth may appear as decayed in xrays. If you can link the reports you have seen I can look at them and comment on it. | |

| Aug 22, 2013 at 5:57 | comment | added | Randy | That makes sense. Thanks so much! I've seen reports of decayed enamel before eruption. Is there truth to this? If so, how does enamel decay before exposed to food acids? | |
| Aug 22, 2013 at 5:35 | comment | added | Ram Manohar M | Where as dentin forming cells are retained live on the pulpal side. So reparative dentin can form on the pulpal side and not on the cavity side to fill it up. These are well established facts which can be found in any standard book on Oral and dental histology and Oral Pathology. Feel free to ask further clarification if required. | |
| Aug 22, 2013 at 5:34 | comment | added | Ram Manohar M | Enamel is not formed at the time of eruption, it is formed before eruption. Enamel is secreted as an organic matrix which subsequently gets mineralised by cells called ameloblasts from inside out. Enamel formation is completed before tooth eruption. After enamel formation the ameloblasts regress and are completely lost after eruption. So no further enamel formation is possible if there are no ameloblasts. Hence once a cavity is formed in the enamel it cannot get filled up with enamel. | |
| Aug 21, 2013 at 4:08 | comment | added | Randy | I see you're an oral pathologist, so your answer has merit. However, can we improve the answer with some explanation or reason to believe the things you say are true, other than just your testimony? I'm not suggesting what you're saying is false, I just want to be 100% convinced. I do appreciate your answer and hope you're not offended by my request. How do we know enamel cannot heal because it was formed at the time of eruption? Why can't dentin heal cavity formation? How does dentin produce a protective barrier? Thank you! | |
