The standard/rule of thumb answer is: crown. After a tooth is hollowed out to clean out the affected nerve, the tooth is weaker and likely to fracture. Covering up completely is best.
If the access hole is small, sometimes nothing is needed, but the lower front teeth are so small that small holes are still very large (by proportion). If the access was from the front of the tooth, a veneer might work.
So truly, the best person to ask is a dentist that is right there looking at the...
As a general rule, full crowns are recommended following root canal therapy to protect the biting strength of the treated tooth and protect it from a non-repairable fracture. For this reason I would lean towards the full crown.
I don't think you could go wrong choosing to have a crown done on a root canal tooth. You might get away with a veneer only if there is very little tooth structure missing. As far as internal bleaching, you usually only need that if you aren't doing a crown.
Its a very good question . There are different options for a RCT treared tooth , specially if it is discolored. Its very important for a tooth to have a full coverage after treatment as the tooth becomes brittle . Veneer covers just the front surface and does not provide the full coverage. Internal bleaching can be an option only when you are not planning to get any crown or veneer after RCT. The best option is to get a crown in order to prevent the fracture of the tooth n...
I would recommend treating your lower anterior tooth with an emax crown. It could be a full crown or 3/4 crown depending on the situation. This tooth can be treated after the root canal is completed. I would also recommend a ceramic post to be placed in conjunction with the root canal treatment. The goal is the create and strong tooth with beautiful esthetics.
Veneer or crown on a tooth with root canal treatment
For teeth in the back of the mouth and middle area (molars and premolars), full coverage crown is recommended. However for front teeth, it may be possible to do a veneer or a partial coverage crown, depending on the tooth itself and howmuch of healthy structure it has remaining.
Most teeth treated with root canal therapy need crowns, in some cases front teeth do not
Typically, teeth treated with root canal therapy should recieve a crown if they are located in the back of the mouth.
Some front teeth can simply be filled with a filling. The determination is a clinical one that is made by the treating dentist and is specific to the circumstance leading to the root canal. If there is a lot of healty remaining natural tooth, a crown may not be necessary on a front tooth. Most root canal treated back teeth do need a crown on the other hand.
With lower anterior teeth the way to treat them in this situation (after root canal) is to clean the inside of the tooth, place a fiber post and do a porcelain veneer that is designed like a 3/4 crown.
This is the most conservative and esthetic approach.
