Porcelain All-Ceramic Crowns
Dr. James Miller can repair damaged or lost tooth structure with porcelain crowns, restoring the tooth to optimal beauty and strength. The most beautiful cosmetic dentistry requires that the doctor use an exceptional and highly skilled ceramist and not a high-volume lab designed to focus on speed, not quality. Dr. Miller works only with the very best laboratory technicians and works with them one-on-one to ensure perfect results.
Crowns are necessary when a tooth is significantly broken down and a filling will not offer good long-term protection. If a tooth is cracked, a crown can stabilize the remaining tooth structure so that the damage doesn’t get worse.
Crowns are also used in these scenarios:
- To replace a large filling when little natural tooth structure remains
- To attach a bridge to replace missing teeth
- To protect a weakened tooth from fracturing
- To restore teeth that are already broken
- To cover badly shaped or discolored teeth
Crowns restore essential function by covering or “capping” a worn, broken or decayed tooth surface with a lab-formulated crown. Dr. Miller only wants to deliver crowns that are made from the most beautiful and strongest porcelain. This commitment to superior aesthetics and fit is why he still utilizes a dental laboratory rather than offering same-day crowns that have little character or beauty. He employs exacting standards for all of his dentistry, making no exceptions for your crown.
Teeth need to be able to withstand great pressure to allow for a stable and comfortable bite. When done right, this type of cosmetic dentistry can improve function and beauty, providing proper occlusal relationships and tooth anatomy complete with sharp cusps, which are characteristic of youthful teeth. We make sure your teeth have the proper structure to restore comfort and function to your smile.

To prepare the tooth for a crown, it is reduced so the crown can fit over it. An impression of prepared teeth and gums is made and sent to the lab for the crown fabrication. A temporary crown is fitted over the tooth until the permanent crown is made. On the next visit, Dr. Miller removes the temporary crown and cements the permanent crown onto the tooth.
Yes. Dr. Miller’s goal is to create crowns that look like beautiful natural teeth. To achieve a certain look, a number of factors are considered, such as the color, bite, shape, and length of your natural teeth. Any one of these factors alone can affect your appearance.
If you have a certain cosmetic look in mind for your crown, discuss it with us at your initial visit. When the procedure is complete, your teeth will be stronger, more comfortable and exceptionally beautiful.
Crowns require more tooth structure removal, hence, they cover more of the tooth than veneers. Crowns are customarily indicated for teeth that have sustained significant loss of structure, or to replace missing teeth. Crowns may be placed on natural teeth or on dental implants.
There is no difference between a cap and a crown.
Crowns should last at a minimum of 5-8 years. However, with good oral hygiene and supervision, excellently fabricated crowns can last decades. Some damaging habits like grinding your teeth, chewing ice, or fingernail biting may cause this period of time to decrease significantly. That is why we always evaluate your bite prior to making any permanent restoration in your mouth. We may mount a set of your models of your teeth on a special articulator to correctly diagnose how to improve your bite, or we may recommend that you see an orthodontist to have your bite correctly fixed prior to restoration with crowns.
To prevent damaging or fracturing the crowns, avoid chewing extremely hard foods, ice or other hard objects and using your teeth as tools to cut or open things. You may also want to avoid teeth grinding. Besides visiting your dentist and brushing twice a day, cleaning between your teeth is vital with crowns. Floss or inter-dental cleaners (specially shaped brushes and picks) are important tools to remove plaque from the crown area where the gums meets the tooth. Plaque in that area can cause dental decay and gum disease.
There are dentists who utilize a technology to fabricate a crown while you wait, while this technology is interesting it has several limitations. The first being that it only restores your tooth to what it looked like just before the procedure, this means if your natural tooth structure has been lost over time due to pathology in your bite, this technology will not correct this less than ideal function and esthetics. Another limitation is the precision in the margins of the crown (where the edge of the crown meets the tooth), minute deficiencies in this area can lead to failure of the crown much sooner.
One limitation is that the restoration fabricated for your tooth can only be made to look like your original worn out tooth. Another limitation is the poor precision or fit of the margins of the crown (this is where the edge of the crown fits to the tooth). Deficiencies in this area can lead to early failure of the crown due to leakage and decay.
