Restorative & Cosmetic Dentistry
Crowns are full coverage restorations that are used to cover a tooth that is likely to break, or is too broken down to be restored with a filling. They are most commonly done after root canal treatment, or when a large filling wears out. The larger the hole made by a cavity that has to be treated, the more likely a crown will be needed. Crowns fit over the weakened tooth, providing strength and protecting the tooth against further breakage.
It takes two appointments to restore a tooth with a crown. First, any decay is removed from the tooth and it is shaped to accept the crown. Then an impression is made of the tooth for use in fabricating a crown.
Between the two visits, the permanent crown is made, usually of high-strength porcelain over gold alloy, all ceramic material, or gold. During this time, a temporary crown is worn. In the second visit (typically two weeks after the first), the temporary crown is removed. The permanent crown is adjusted as needed, and then cemented in place.
A dental implant is an option to replace a missing tooth. In this procedure, a small titanium shaft is surgically implanted into the bone and allowed to set. The bone grows around it forming a tight connection, which additionally slows or stops the bone loss that occurs when the root of a natural tooth is missing. Once the implant is firmly set in the mouth, the dentist attaches the replacement tooth onto the top of the shaft.
This permanent solution has advantages over bridge work in that it does not stress the surrounding teeth for support, and, should the tooth wear out, another can simply be replaced on the shaft.
Implants can also be used as support as part of an implant bridge. This is an alternative to partial dentures, and has several advantages. First, there is no adjustment period to acclimatize the patient who, once the work is done, only feels teeth, not metal supports intruding into the mouth. Second, this slows the bone loss occasioned by missing teeth. Third, there is no discomfort or difficulty in eating. And, best of all, of course, they don't have to be taken out all the time.
Our promise to you is that the veneers, fillings, crowns, and bridges we create will look as good as - or better than - the teeth nature gave you. And to make sure we keep that promise, the products we recommend and use are of the highest quality.
