Risks & Side Effects


Dental crowns are easy to care for, and the treatment process is associated with a low incidence of complications and an easy recovery period. Here we review the recovery period, aftercare tips, and possible risks for dental crowns.


For two to four hours after the dental crowns procedure, patients will experience numbness in the mouth area. During this time, patients should avoid accidentally biting down the tongue or inside of the cheeks to avoid injury.

Once the numbing medication has faded, patients may experience minor tooth sensitivity to hot or colds foods or when biting down on the affected area. Patients may want to avoid temperate foods and drinks and chew on the other side of the mouth for two to three days after treatment to avoid any potential discomfort. In most cases, any lingering tooth sensitivity is gone within a week of the procedure.


After having dental crowns placed, patients can adopt a normal oral health care routine. This includes brushing the teeth at least twice a day, flossing daily, and seeing the dentist at least twice a year.

Possible Complications with Dental Crowns

As with any medical treatment, there are risks involved with the dental crown procedure. Although choosing a qualified and highly acclaimed dentist to treat your oral condition greatly reduces the chance of complication, problems can still occur.

Removal of healthy tooth structure: Preparing a tooth to receive a dental crown requires the removal of some enamel. At times, this enamel is perfectly healthy, but is removed to make room for the restoration.

Thin or perforated tooth surface: During the preparation process, it is possible for the tooth's surface to be made too thin or perforated by an instrument.

Nerve damage: The tooth preparation process could result in the damage of your tooth's nerve. If this occurs, root canal therapy or removal of the nerves may be required.

Tooth sensitivity: With crowns made partially or entirely of metal, sensitivity to heat and cold may occur. Your teeth naturally expand and contract in reaction to changes in temperature, but artificial materials may react at a different speed, resulting in higher sensitivity. Special toothpastes can often lessen this side effect.

Bite misalignment/TMJ disorder: Although dental crowns have remedied some cases of TMJ disorder, they can also exacerbate TMD if placed incorrectly. Once a dental crown is placed, the dentist should check the fit in accordance with the surrounding teeth as well as the bite as a whole. If you experience headaches or shoulder pain after a dental crown procedure, it is important to see your dentist.

Allergic reaction: Modern technology has made it possible for patients to receive dental crowns in a variety of materials. It is advised that an allergy test be done before undergoing a dental crown procedure to avoid a harmful reaction to one of these materials.

Infection: If your dental crown is not properly sealed or if damaged material is not completely removed, decay can spread. Additionally, dental crowns that are not properly cared for with brushing, flossing, and regular checkups can increase your risk for further decay, damage, and disease.
