How the Dentist Prepares Teeth for Dental Crowns

Dental Crown Chicago, IL

When teeth are severely decayed or damaged, dental crowns may be able to restore them so they do not have to be extracted. Dentists prefer to leave natural teeth in the mouth whenever possible. A crown is a cap placed over a damaged tooth, restoring its original function, appearance, and strength.

Placing a crown traditionally requires two visits. The tooth is prepared during the first visit, and the data needed to create the crown is sent to a dental laboratory. A temporary crown is placed to protect the tooth, and a second visit takes place within a week or two to cement the permanent crown in place once it is ready.

4 steps to prepare teeth for dental crowns

The following steps are usually involved in preparing a tooth for a dental crown. They may not always take place in the same order, and there may be some variations.

1. X-rays

At the first appointment, the dentist may take X-rays to check the tooth and its roots, as well as the bone that surrounds it, to be sure that it is healthy and stable enough to support the crown. However, if you have recently had dental X-rays taken, this step may not be necessary.

2. Numbing

The dentist uses a local agent to numb the area around the tooth receiving the crown. You should not feel anything during the procedure.

3. Digital Scan

Many dentists are now using digital imaging technology to scan images of teeth to collect the data needed to make molds for dental crowns. The dentist will use a small intraoral handheld scanner to take 3D images of the teeth. This method is quick and more comfortable than traditional impressions, resulting in detailed images to create a dental crown that replicates the patient's natural teeth. 

4. Reshaping

Reshaping is the most crucial step in preparing the tooth. To fit a crown, the outer structure of the tooth often has to be reduced in size by removing some of the enamel. If the tooth has been filled in the past, the filling material is removed as well. The dentist uses tools to remove precise amounts of the tooth. How much material needs to be removed depends on the type of crown. If it is all metal, less tooth material needs to be removed because all-metal crowns are thinner than other types.

Conversely, sometimes the tooth may be so damaged or decayed that a large area is missing. In this case, the dentist may have to use filling material to build up the tooth enough so that it can support the crown.

Caring for dental crowns

The materials used in dental crowns are highly durable and are designed to last for many years. However, it is important to take proper care of this type of dental work because damage and wear and tear can still occur. First and foremost, make oral hygiene a high priority. Brush twice a day with fluoride toothpaste and floss once a day. These practices will lower your risks of developing tooth decay and gum disease, which can affect the lifespan of a dental crown. See your dentist at least twice a year for routine cleanings and checkups to help control tartar buildup and detect any potential issues early on.

It is also important to monitor your dietary and lifestyle habits. Extremely tough or crunchy foods can damage a crown, especially if you consume them often. Chewing on foreign objects or grinding your teeth can also cause a crown to chip or crack, requiring a new one. While porcelain crowns are highly resistant to staining, they can become discolored if you smoke or consume a lot of coffee, tea, or red wine. In addition, excessive alcohol consumption can weaken the adhesive used to mount the crown in place. This is also true of mouthwashes that contain high concentrations of alcohol, so look for alcohol-free alternatives instead.

Conclusion

Temporary dental crowns are placed at the first visit after the teeth are prepared. Once a permanent crown comes back from the lab, the temporary crown is removed and the permanent one cemented in place to restore the patient's tooth. Dental crowns can last for many years with proper care.
