What Might Cause Discomfort During a CEREC Crown Fitting?

How often do people have jaw pain? Or tooth sensitivity? Is CEREC a good option to other crowns for those with TMJ who don't like to spend too much time at the dentist?

CEREC crowns

CEREC crowns are bonded crowns and sensitivity is a concern for all bonded crowns. As long as a good system is used for bonding the crown and the manufacturers technique is followed correctly, it's usually not much of an issue today though. CEREC can be done in one visit and with an experienced doctor you really should have no problems.

CEREC visits CAN be easy

Quite often the visit is a series of short procedures with many breaks.  A person with TMJ issues could rest in between these procedures.


However, most of MY TMJ patients do better with two short visits instead of one very long visit.

Cerec Crowns are a great alternative in many cases.

A Cerec crown is a great alternative in many cases. The beauty of this type of crown is that it involves on visit and there a not any traditional impressions used. This procedure should not create any more TMJ issues than any other crown. Cerec crowns fit well and if done properly will last a long time.

Cerec restorations avoid a multitude of problems

Cerec restorations avoid a multitude of problems including sensitivity, loss of temporaries, only one visit instead of two meaning you are only numb one time.

They do not prevent TMJ disorders or cure them and your dentist must be very occlusally oriented to prevent problems.  In the right hands CEREC can be amazing in the wrong hands a total disaster.

I strongly suggest visiting a neuromuscular dentist with several years experience if you are contemplating a CEREC restoration.  Neuromuscular Dentists understand the underlying physiology of occlusion.  Patients with chronic headaches and TMJ disorders can learn more about Neuromuscular Dentistry at IHATEHEADACHES.org

Cerac-causes for discomfort?

There really are no reasons why a cerac crown would be more sensitive then a traditional crown and it should actually be less sensitive if done correctly.  Due to a smaller amount of tooth removal in most cases and a single visit of work on the tooth, tenderness is much reduced.  Adequate local anesthetic, and desensitizing cements and liners should take care of any problems.  TMJ issues need to be considered in mouth opening prior to start and the visit can be adjusted to accommodate problems most of the time.  Good luck!

CEREC is a Nice Alternative

The use of the CEREC system is great for those that have time constraints and cannot, or do not, want to return to the dentist for second visit crown fittings.  Also it is great for gagger's as the "impression" is taken with a scanner and conventional impression material is not used.  However, It is not for everyone or every tooth for that matter.  While the crowns are milled by computer and fit beautifully, there is a learning curve to the design and fabrication of the crowns.  Therefore, be sure that the doctor or staff member designing yours has plenty of experience.  Also the crowns are ceramic and if overloaded with a very strong bite, are more prone to fracture than a conventional porcelain to metal or full metal crown.  Inserting CEREC is more technique sensitive than conventional crowns and because the crowns are bonded to the tooth, there is more chance of sensitivity than a conventional crown.  In the right hands, sensitivity should be easy to avoid if the techniques of bonding are understood and closely followed. As far as TMJ is concerned, I see no difference in either technique.  The preparation time and insertion times are similar.  The difference is they are spread out over two visits with conventional crowns versus one longer visit with CEREC.

Cerec Crowns should be comfortable

Cerec crowns are really no better or worse for someone that suffers with chronic jaw pain or tooth sensitivity.  However, for the person who gets sore muscles/TMJ from having to keep their jaw open during a dental visit or has especially sensitive teeth after they have been worked on, Cerec is a great option.  Cerec crowns and restorations can be completed at the same visit that the tooth is prepared and thus allowing for less time in the dental chair overall.  And, the tooth is usually already anesthetized during placement of the crown so there is no need to worry about sensitivity during the cementation process.  The only thing I can think of that might cause discomfort during a cerec crown fitting is if the anesthesia wore off.
