Dr. Urban on Today’s Dentistry/Save teeth or replace with implants?

If you have a severely broken down tooth, how does your dentist determine the type of treatment with the most favorable outcome? The decision is not always easy or clear cut. If your dentist saves a tooth how long will it last? If the tooth is removed what will be the replacement? These are the choices and each choice has consequences.

Suppose a decision is made to save your tooth with a root canal treatment. A root canal treatment is basically a long filling that seals the tooth from being an avenue for bacteria to enter the bone and bloodstream. A tooth treated in this way need a filling or crown to hold it together and to protect the root canal filling material that is placed inside.

Over time the root canal treated tooth becomes dehydrated and brittle. It is susceptible to fracture, recurrent leakage, and failure. Although the treatment was 100% successful the tooth can eventually fail anyway. This may take many years. So if the tooth may fail why not just extract it and place an implant? Remember that most teeth treated in this way last from 7-20yrs (or longer). In other words its useful life expectancy was longer than that of most automobiles. The fee range for this service is about $2500.

Suppose a decision is made to replace with an implant-supported tooth. Implants are titanium (a most biocompatible material) inserts placed into the dental bone. A metal top (abutment) is screwed onto the implant (no anesthetic is necessary) and a crown made over the metal top. Although this process takes many months I have been very pleased with the minimal discomfort experienced during this process. Implant placements have reached a 98% success rate. Conceivably once the implant “takes” it can last a lifetime if proper home care is used. The cost for this procedure is about $3700-$5000 per tooth.

Implants can fail from breakage in one of the components, bacterial disease, or loss of bone around the implant. If 98% succeed, then two out of a hundred do not and the procedure has to be repeated.

There is an argument that can be made whether we should save a tooth at all costs or extract and place an implant. Are root canal teeth “implants in training” as one of my colleagues says? Over many years the cost difference will have been erased with the increased longevity of the implant. Furthermore, once the root canal treated tooth is ultimately removed it will need replacement. Would it be better to extract sooner than later? This depends upon you, your financial wherewithal, and your dentist.

In my practice I like to preserve teeth as long as possible. I know that I will not be the only dentist over a person’s lifetime and I try to save as much as possible for future dentists. I believe that dental technology and biologic research may ultimately make both root canal treatments and implants a thing of the past.
