Side Effects of Dental Crowns and Full Mouth Reconstruction

Dentists use dental crowns and full mouth reconstruction to help patients who have missing or discolored teeth due to gum disease, tooth decay, infection or injury. Dental surgeries such as crown placement and implants are costly, ranging from about $1,100 per crown to up to $45,000 or more for a full mouth restoration. According to the Columbia University College of Dental Medicine, 90 percent of dental implant surgeries are successful.

Bleeding, Pain and Nerve Injury

Dental crown and full mouth reconstruction surgery, like any type of surgery, carry a risk of bleeding, according to the Columbia University College of Dental Medicine. Dentists may inadvertently touch the jawbone nerve during these procedures, leaving you with pain and numbness in the lip, chin or tongue that could last several months or remain permanent.

Tooth Sensitivity

Once the anesthesia from your dental crown procedure begins to wear off, the tooth crown may feel tender and uncomfortable. According to the Cleveland Clinic, newly crowned teeth are prone to sensitivity to hot and cold temperatures. To combat this side effect, brush your teeth with toothpaste designed for those with sensitive teeth. If your tooth hurts when you bite down, visit your dentist for a simple procedure to adjust the height of the crown.

Tooth Decay and Infection

Dentists use cement to hold the dental crown in place, but cement can loosen and wash out from under the crown. A loose crown allows bacteria to accumulate on the remaining tooth and sometimes causes tooth decay and cavities. If you have a loose crown, your dentist may need to re-cement it or fit you for a new crown to prevent tooth decay.

During full mouth restoration procedures, bacteria can infect the gums around dental implants, causing periodontal disease known as periimplantitis, according to the Columbia University College of Dental Medicine. Eventually, untreated gum infection causes bone loss and the implant to weaken, requiring additional dental work.


Dental implants, such as those used in full mouth reconstruction, or dental crowns can break, especially if your bite is misaligned. In addition, if you experience bone loss in your jaw, the implants can loosen, break or fracture, according to the Columbia University College of Dental Medicine.

Allergic Reaction

Rarely, people who have dental crowns or implants that contain metal can experience an allergic reaction that causes immune system problems and chronic fatigue syndrome in dental patients, according to the Cleveland Clinic Foundation.
