Can a Traumed Yellow Tooth Be Whitenend? Its Between Dark/light Yellow.

When a tooth discolors after it has taken trauma it typically means that the nerve is necrotic (dead).  With these teeth many times you will need to first have the tooth treated with a root canal.  At that point, you could try internal bleaching.  It is not the most predictable procedure as far as how much it will whiten, but it is a conservative place to start.  A more predictable aesthetic result would be to place a veneer or all ceramic crown on the tooth that matches the remaining teeth.  

Try the following sequence:  Make sure your tooth does not need a root canal-Sometimes teeth die and a yellowing tooth can be the result.  Then -1-Try custom whitening trays-My banker drove me crazy with his one yellow tooth.  I offered to have him whiten -no charge-It worked!!!!   2-Try Internal whitening if it has a root canal and when it is done if the dentist uses IRM as the plug under the filling the odds of resorption go down.  (Resorption can occur on any tooth but that is when the tooth attacts itself.)  3-You can always do a veneer to cover the discoloration.  Just remember, once you do a veneer, it is permanent.  Good luck-Start conservative and work it through.

You may be able to whiten the tooth.  If you already had a root canal your dentist can internally bleach the tooth and add some external bleaching as well.  If the tooth does not have a root canal then only eternal whitening like KoR can be preformed. 

You can make an attempt to bleach lightly darker tooth. It can take a combination of endodontic treatment and internal or external bleaching. Sometimes the result is very good, and sometimes not. It is the most conservative first step. If that doesn't work then covering with an artificial material like porcelain veneer would be a solution. So it is up to you if you want to go more conservative or more aggressive.

Depending upon the degree of trauma, you possibly will require endodontic treatment if the pulp in the root canal is not vital anymore. It can be evaluated with simple test by the dentist. External bleaching techniques can significantly improve the color of stained and traumatized teeth. Internal bleaching should be used very carefully due to high concentrated amount of active ingredient and possible high degree of complications. In cases when the bleaching procedures are not extremely effective the esthetic results can be improved with porcelain restorations. 

If by " traumed tooth"  you mean a "traumatized tooth", then there are two ways to take care of the discoloration:

1) internal bleaching - a procedure that has quiet a bit of risk of internal resorption . unpredictable results

2) veneering

HOWEVER, and most important is that the discolored tooth has / will have a completely necrotic nerve( dead nerve) and needs to be treated with root canal first and sooner is better than later, once the discoloration begins , it only get darker and harder to mask.

 

Good luck

If you have a traumatized tooth, you may be able to whiten it.  First be sure that the tooth has a vitality test.  If necessary complete the root canal, then you can whiten.  If the tooth has had root canal, your dentist can use a combination internal/external whitening method.  If it is alive with no root canal, then only external whitening can be performed.  In either case, be sure to overwhiten the tooth.  That is, beyond the color of adjacent teeth, so that it fades back to the color of the others.  Whitening individual teeth like this is not as predictable as routine whitening cases and does require more up-keep on your part.  

Good Luck!
