Dentin

Question: My dentin is exposed bec new dentist polished the back of my two front teeth. Can I re grow my enamel back? She only filled the eposed dentin but i'm not comfortable with it. it bothers me a lot and it still aches. what will i do? will this heal?

Answer: what i can say, enamel is not a vital part of teeth. it will not grow back if the structure loss due to caries/fracture/iotrogenic cause.. if the loss very minimal, it can be remineralized by toothpaste(fluoride content inside toothpaste do the action). what u can do now, meet your dentist and explain your problem im sure he will understand.. Good Luck :)

Question: Is there a procedure to cover up the exposed dentin on my teeth? FYI: I would prefer that a dentist answers this question. I used to brush too hard and the enamel has been wearing away gradually near my gums on 5 and 11. Just recently, the exposed dentin has become seemingly more sensitive (it hurts to barely touch it with my toothbrush). Isn't there a procedure where the dentist can take tissue from the roof of my mouth and use it to cover up the exposed dentin?

Answer: A better solution than a graft procedure would be to bond a composite filling over the exposed dentin. Erosion at the gumline due to abrasion is very common and the cheapest and simplest way to take care of that is do a direct bond procedure. BTW, using an electric toothbrush will prevent excessive wear on your teeth. Most people brush too hard, incorrectly, and worse of all, sideways at the gumline. Brushing like that literally saws the teeth off and creates notches at the gumline. It is also a very hard habit to break. The problem with brushing correctly is that you don't get that "fresh and tingling sensation" afterwards and this makes people brush harder to get it. Of course when they do, they go overboard and this results in exceesive wearibg away of the teeth. The only time the surgical procedure you described is done is in periodontics when the tissue is denuded over half the length of the tooth.

Question: is Dentin really white? and What can I do to make it less sensitive? I just went to the dentist for fillings and I find that there is a small part that is alot whiter and much more sensitive than the rest of the tooth. I looked it up and it seems like its the dentin but im not sure.

Answer: Dentin is a yellowish gold color, not white, and is normally covered over by enamel. Tooth colored fillings are known to cause sensitivity and many times will slowly go away on its own.

Question: How can you stain the dentin back in on a bleached out deer jaw bone? I am taking a Wildlife Biology class and our instructor has some jaw bones that were bleached. This bleached everything out...this makes aging more difficult as you cannot see the change in color, so to speak. Does anyone know of a way to put the color back in? Basically staining the dentin so we can see it?

Answer: Well, I'm not sure, but dentin is porous, whereas enamel is not. You should be able to add a food dye to the teeth, let it soak a bit, then rinse. It should come off of the enamel, but stay on the dentin to some extent. I would use orange, since that would give better contrast. If you have access to a collagen dye, then you may be able to use that. The enamel is all mineral matrix and the dentin contains collagen. The bleach will have denatured the collagen a bit, so it might stick better. Hope this helps

Answer: Try asking in health - dental section

Question: Dentin - remineralizing pastes claim they can harden it but how do they get to it through the enamel? Can these toothpastes with ACP, novaMin and others penetrate the entire enamel and then move into the dentin? Even toothpastes for sensitive teeth say they block dentin tubules, but how do they get through the enamel - the body's hardest substance?

Answer: The dentin tubules are on the root of the tooth, not the crown, where the enamel is located. If you are having sensitivity due to root exposure, then your dentinal tubules have been exposed. These toothpastes "plug up" the tublules, preventing sensitivity. If there is an opening in the enamel, that is most likely decay, and would need to be treated professionally.

Question: About 1 year ago, my orthdontist did proxymal grinding and exposed dentin layer? It has been extremely sensitive and painful when I floss. The dentin was exposed below and just above the gum line. Is there anything I can do to speed up the regrowth process of the enamel? Is it even possible for the enamel to regrow in that area?

Answer: Unfortunately, once the enamel is removed it will never come back.

Question: Tooth decay into the layer called dentin please help? My tooth has decayed into the layer called dentin what can I do to prevent my dentin from decaying any farther, will flouride help? Or is it too late for that?

Answer: i'm sorry to say, but if your decay has extended into dentin, you're gonna need a filling. flouride won't help reverse decay that has gone into the dentinal layer. your teeth consist of three layers: outer most is the enamel, in the middle is the dentin, and at the center is the root, which consists of nerves and blood vessels. if a cavity is still only in the enamel, flouride can help make the decay go away. but if tis your dentin, you'll need a filling. if its too deep into the dentin, and into your root, you'll need a root canal. hope that helps

Question: How long does it take for a cavity to reach the dentin of the tooth? I have to wait two weeks until I get my cavities fixed. Is that too long to wait? * Because I heard if the cavity reaches the dentin I have to get a root canal and I DON'T want a root canal instead of a filling.

Answer: It takes 2 to 3months as dentine is softer than enamel

Question: What is the best treatment for exposed dentin, causing the teeth to look yellow by the gumline? Knowledgeable answers only, please, I need to know how to hide the exposed dentin

Answer: Ask your dentist to clean it up and provide bleaching. Then maintain by having this anti plaque mouth wash.

Question: What if my cavity has reached me dentin? I've been looking around and ive seen that the next layer of your tooth is the dentin.when i look at my cavities(my front teeth) they seem to have reached that area. Will i have to get a root canal, or i i make it to the dentist soon, will it just be a normal filling? im nervous because i dont want any root canal :(

Answer: You don't necessarily have to get a root canal so don't worry ;) If the cavity reaches the dentin, it just means it's deep...but the problem is how deep it is. If it's not that deep, u'll just get a regular filling..however, if it's very deep and there's a lot of caries..it may reach the pulp and u may get a root canal..i suggest u go to the dentist asap ;) Good Luck!

Question: Does Zoom Advanced Whitening process penetrate the enamel to make the dentin whiter? How much whiter? Thankyou RDH and spongebob for your answers. I have no stains on my enamel and it is very good enamel (hard and shiny)but my dentin has a yellow color and I was told by a dentist this particular process would penetrate past the enamel and whiten the dentin. Any further technical explanation on this particular Zoom Advanced process would be appreciated OR if anyone knows how to whiten Dentin?

Answer: Any of the bleaching systems are only working on enamel. And none of them is permanent, since you pick up stains on your teeth from diet and habits. All systems, from the $30 one in the drug store to the $1000 system at the dentist require touch-ups in order for the teeth to continue appearing whiter. Dentin is the layer of the tooth protected by enamel. While enamel is bone, there is a misconception that dentin is bone too, but darker. Dentin isn't bone; it is tubules that lead right into the pulp or nerve. You do not want to have exposed dentin, trust me.

Question: What is the smear layer of the dentin in spanish? I need to know what does that mean in spanish.

Question: Can a dentist accidentally damage your dentin with their tools? with their sharp metal tools poking around I read that they can damage your tooth's dentin

Answer: No they can't because dentin is under the enamel.

Question: How will they fix a lateral incisor if it has a piece missing(near the gum) and the dentin is showing? Do they fill it in the missing spot? Or do they remove it and replace it with a fake one? D:

Answer: Depends on how much is missing--they can build it up with some composite. I have a tendency to brush to hard, and I have had some exposure over the past few years, which my dentist has covered nicely with tooth-colored composite. Good luck!

Question: What is the thickness of enamel and dentin in decidiousand permanent teeth?

Answer: It varies considerably depending on what particular tooth you are talking about. There are many dental anatomy books that contain this specific information.

Question: Sufferers of enamel loss who have tried veneers or bleaching to hide dentin; are you pleased with outcome? I have enamel loss caused by excessive brushing on 2 visible teeth, so need to decide whether to have veneers or bleaching, thanks i'm male........

Answer: Bleaching will not fix enamel loss. There are special toothpastes on the market that I think can rebuild enamel bt for a fast fix you would need veneeers. My sister has had them done to correct the same problem (where the tooth almost becomes "see - through") and the result is fantastic ---- so if you can afford the treatment go for it ;)

Question: Does anyone know where i can find a picture of what a exposed root or dentin looks like on a tooth? what color i have a hole that broke off near the gums and i want to know if it extends to the root. it is brownish red i think (hard to see cuz its a back tooth.

Answer: Type 'gum recession' on any search engine and look for pictures. It is usually brownish yellow, but with stains (coffee and nicotine) can appear much darker.

Question: can you repair your enamel on your teeth when the dentin is showing? Hi wayne thanks for ur answer it is really good to know somebody thats going thru the same thing cos i always think i am on my own but i am not thanks once again thanks for ur answers but i cannot afford vaneers or anything cosmetic, is there anything else i can have apart from that??

Answer: Hey chelsey, I actually thought of your question yesterday, last night when I went to bed. Anyways, Its very hard to get enamel back after it is completely gone. I've tried everything and it just does not work. Sure you can go to the dentist, he can buff your teeth to be white, with zero stains. But after awhile they will come back. And after that, your teeth will start to rot. To be honest, As soon as I find another job *as I lost mine awhile back* I will try to get dentures. Like you, I just want nice teeth. Its somewhat embarassing to have messed up teeth because people judge you, and think you are "unclean" and other things. I still use enamel protective toothpaste, but at this point its kind of pointless. I wish I knew you personally, because being alone with this problem is hard, and no one really understands the daily struggle with it. Good luck Chelsey.

Question: How is Tertiary dentin form and what causes it to form?

Answer: It is also known as repairative dentine and is is basically how your teeth respond to infection (decay). It is created to increase the amount of space between the infection and the pulp of the tooth, which is full of nerves and blood supply. It is formed by odontoblasts (dentine producing cells) depositing dentine. Hope that helped.
