Risk of Infections- Veeners Vs Crowns With Root Canal?

root canals have the risk of infections you may not be aware of because the root has been removed. with crowns you are also putting another tooth on top of a shaved down tooth. would veneers be less likely to be at rest for infections?

When root canal "therapy" is done the root is not removed. It is actually about saving a tooth and preerving nervous system inte

I used the trem root canal therapy.  Therapy is the key word.  When it is performed it is meant to maintain a tooth that would otherwise be lost.

The root canal is a space inside the tooth where the cells that form the tooth reside.  When these cells become inflamed a tooth can become very sensitive to hot and/or cold and have spontaneous pain.  This is frequently due to a pressure build-up within the canal.  An acute pulpitis is when there is sudden onset of severe pain from inside the tooth.

A tooth that is sore to touch has an apical periodontitis or inflamation around the tooth.  This causes the tooth to rise in its socket and biting down is a hydraulic pump that is quite painful.

Root canal therapy is cleaning out infection inside the tooth.  When successful the infection is eliminated completely or nearly completely.

Root canal therapy is 95% successful in saving teeth.  That means one in twenty fail.  If you have one of those 5% that fail from your point of view therapy is a complete failure.

It is possible to retreat a failed root canal therapy but there is only about 50% success.

When a tooth is abscessed, ie the infection has spread to the bone therapy does not elimnate the infection only the cause of the infection.  Think of it like a sliver in your thumb which becomes infected, red and swollen.  When you remove the sliver the infection still remains but the imune system will usually eliminate the infection. 

The teeth are connected directly to the brain by trigeminal nerve cells.  When a tooth is extracted (amputated) it actually leads to brain cells dying.  The trigeminal nervous system accounts for approximately half of all input to the brain.  Amputating body parts should never be a first option.

A chronically infected tooth that has had root canal therapy should be extracted.  Sometimes the infected root or tip of the root can be removed leaving the healthy parts of the tooth intact.

Porcelain Crowns or Porcelain Veneers

Generally speaking there is less risk of root canal problems with porcelain veneers than with porcelain crowns.  This is because in most cases a lot less natural tooth has to be removed for veneers than crowns. I hope that this answers your question.

Veneers versus crowns with respect to root Canal

{{ voteCount >= 0 ? '+' + (voteCount + 1) : (voteCount + 1) }}

Firstly the choice to place a Veneer as opposed to a Crown is based on the amount of healthy  Tooth structure available and the goals for that Restoration. In other words Restoration types are not chosen based on their likeliness of causing the need for Root Canal treatment. If a patient presents with chipped,malposed, or discolored teeth than the Veneer may be the better choice based on having ample Tooth structure available and the demand for optimal aesthetics in the "Esthetic Zone" (the area where one can see when a person smiles). If a patient has cracked or fractured a significant portion of a tooth it would require a crown irregardless of the location of that tooth. With all things being equal and assuming that a patient is receiving good Dental care, Veneers are less likely to require a Root Canal as opposed to a crown on the basis that less tooth structure is removed during the preparation process. Having said that if a tooth does require a Root Canal after a crown preparation it would need one based on the tooth becoming inflamed or commonly known as an acute pulpitis. This temporary inflammatory process can be eliminated after a Root Canal with no further concern for an infection over 90% of the time.

As long as the work is done accurately, you will not get decay or periodontal infections on the teeth. You must also brush and floss every day and see your hygienist every three months.

Can veneers be placed on root canal treated teeth

{{ voteCount >= 0 ? '+' + (voteCount + 1) : (voteCount + 1) }}

The Type Restoration on any root canal treated tooth does not have anything to do with your teeth getting infected. All restorations can be placed for different purposes on root canal treated teeth, and all can fail if not properly placed, and properly taken care of by the patient. With root canals, the tooth and the ROOT remain. It is the " Nerve"and the vascular system that is removed from the tooth due to infection and or contamination to infection.

So according to which tooth, and the extent of damage after root canal treatment is completed, the dentist will advise you what  is the best restoration.  Your dentist may advise you to get a crown, or a simple bonded filling. And obviously nothing is permanent, It is then up to you to have great oral hygiene, and routine cleanings to keep your teeth intact and free of infection and keep your dental restorations long term.

Veneers are more conservative than crowns

{{ voteCount >= 0 ? '+' + (voteCount + 1) : (voteCount + 1) }}

If I understand your question correctly, you are asking which of a crown or a veneer will make your tooth more likely to need a root canal treatment.  In general, the more conservative the dental treatment, the less likely that tooth is to need a root canal treatment.  Veneer preparations are minimally invasive and therefore require minimal tooth removal.  Crown preparations on the other hand remove more tooth structure and are more traumatic to the tooth in general.  This does not mean that a crown prep will cause a root canal problem, only that there is probably more risk to the root canal from a crown preparation than a veneer preparation.

Crown or Porcelain Veneer After Root Canal?

{{ voteCount >= 0 ? '+' + (voteCount + 1) : (voteCount + 1) }}

The first priority following a root canal is to make sure the treatment sufficiently has taken care of the source of the problem/infection.  Immediately following a root canal the tooth is temporized with a temporary filling.  Once the tooth is asymptomatic it is time to decide on the best permanent restoration for that tooth. Depending on the tooth the final restoration may be a composite filling, veneer, or all porcelain crown.  Your dentist will make that decision, based on your bite, how much good tooth structure is left, and where the tooth is in your mouth. 

Risk of Infection is not a concern after having a Crown or Veneer

{{ voteCount >= 0 ? '+' + (voteCount + 1) : (voteCount + 1) }}

The major difference between a crown and a veneer are the surfaces of the tooth covered with porcelain and the way in which the restoration is attached.  Typically veneers are bonded and many if not most crowns done in the U.S. are traditionally cemented even though there are exceptions with certain types of crowns.  A posterior or back tooth with a root canal is usually at a higher risk for breaking or cracking after a root canal and generally a crown is the standard of care for this.  The more anteriorly or forward your tooth with the root canal is, the less likely it will need a crown and might be able to be restored with a filling or even a veneer might be acceptable. 

The tooth does change after a root canal sort of like a tree does when it dies.  While the tree is alive, the branches are flexible and you can bend them to a degree without them breaking.  This is like a tooth with all of the nerves and blood vessels present before a root canal.  It is hydrated and somewhat flexible.  When the tree dies its branches snap more easily when they are bent.  Similarly the tooth when it has had a root canal is considered "dead" and looses much of its hydration.  It becomes more brittle and easier to break.

There are other factors as well, but as for risk of infection, neither a crown or a veneer would be more or less likely to have a recurrent infection if the tooth were restored properly.  Hope this helps.

Risk of Infection Does Not Determine if you do a Crown or Veneer

{{ voteCount >= 0 ? '+' + (voteCount + 1) : (voteCount + 1) }}

Having a root canal done does not dictate what kind of dental treatment follows.  We strive to get your infection healed before you do further dental treatment but there is not always a guarantee.  1- For some teeth, you only need a good bonded filling. 2- For other teeth you need veneers to cover the color.   3- Crowns can strenghten the tooth in some instances but not always. I have seen teeth break at the gum line so a crown does not guarantee the life of a tooth.  Find a dentist you trust and ask them what they recommend.  Much success.

Risk of Root Canal Failure vs. Type of Restoration

{{ voteCount >= 0 ? '+' + (voteCount + 1) : (voteCount + 1) }}

The risk of endodontic therapy (root canal) is nor really affected by the type of restoration placed.  The purpose of the restoration is to strenthen the tooth from possible fracture and create a normal appearance.  Whether a veneer or crown is placed usually is determined by the amount of tooth structure available following the root canal.
