7 Common Dental Crown Problems and How to Address Them

Dental crowns are one of the most common dental procedures, which are used to restore and protect damaged teeth. They are the go-to solution for many patients who present with cracked, decayed, or weakened teeth that are causing discomfort or pain. However, dental crowns aren’t a perfect science and are prone to some issues, from sensitivity to falling off. 

1. Discomfort and Sensitivity

One of the most common issues patients encounter after getting a dental crown is discomfort or sensitivity. Discomfort can range from mild to severe and is typically caused by the crown not fitting correctly or being too high on the tooth. Sensitivity can also occur if the tooth's nerve was irritated during the crown placement process.

Discomfort and sensitivity from a crown are first addressed with time, as they may be temporary issues that will subside within just a few days as the tooth adjusts to the new crown. Using desensitizing toothpaste during this time may help alleviate sensitivity. If the discomfort or sensitivity persists, the dentist who performed the procedure should be consulted, and a visit is in order to see if adjustments can be made. 

2. Chipping or Fracturing

Dental crowns are designed to be durable, but they can still chip or fracture if exposed to excessive force or wear. Common culprits are chewing on hard objects, grinding teeth at night, or using them to open packaging.

If you notice a chipped or fractured crown, your dentist should be contacted immediately to assess the extent of the damage and provide treatment. To avoid another chip or fracture after repair, avoid chewing on hard foods or objects, and wear a nightguard if you’re prone to grinding your teeth while you sleep. 

3. Loosening or Falling Off

It’s not uncommon for dental crowns to become loose or fall off, which usually happens due to inadequate cementation, decay under the crown, or trauma to the tooth.

These are situations that require immediate attention from your dentist, and you should avoid attempting to reattach the crown yourself to avoid further complications. If your dentist cannot see you right away, use dental adhesive from the pharmacy to temporarily reattach the crown. This is a short-term solution that should help until you can see your dentist. 

4. Gum Recession and Crown Margin Exposure

Gum recession is when the gum tissue pulls away from the base of the tooth, exposing the crown's margin, which is the space between the crown and the natural tooth. This can make the crown appear unsightly and cause decay in the underlying tooth structure.

This is a scenario that is often caught during a routine dental exam when your dentist checks your gum health. Gum grafting is a corrective option to restore lost gum tissue and cover the exposed crown margins, which your dentist may recommend depending on the degree of recession.

5. Allergic Reactions to Crown Materials

Some individuals may develop allergic reactions to the materials used in dental crowns, which can include metal alloys or ceramics. This can lead to symptoms such as gum inflammation, pain, or discomfort.

If you suspect an allergic reaction, consult your dentist immediately. They can determine the cause of the reaction and recommend an alternative crown material. If you are prone to contact allergies, let your dentist know, as patch testing can be performed to identify an allergy prior to a crown being placed.

6. Tooth Decay Underneath the Crown

One of the biggest advantages of dental crowns is their ability to protect and strengthen damaged teeth. However, if oral hygiene is neglected, tooth decay can develop underneath the crown and cause issues.

In order to avoid this, maintain excellent oral hygiene with regular brushing, flossing, and the use of an antimicrobial mouthwash to prevent decay. Make sure to clean around the crown area thoroughly and consistently. Also, visit your dentist for regular check-ups and cleanings to detect any signs of decay early. Your dentist can take X-rays to check the condition of the tooth underneath the crown. If decay is found, your dentist may need to remove the crown, treat the decay, and replace the crown.

7. Esthetic Issues

Dental crowns are designed to mimic the appearance of natural teeth. However, esthetic issues can arise, such as color mismatch between the crown and adjacent teeth or an unsightly appearance. If you're unhappy with the look of your crown, discuss your concerns with your dentist. They may recommend a new crown or alternative solutions, such as veneers or teeth whitening. Dentists can also work with dental laboratories to select a customized shade that closely matches your natural teeth, providing a more pleasing result.

Dental crowns are a common and valuable dental procedure that can restore the function and appearance of damaged teeth. However, they aren’t without potential challenges. By maintaining good oral hygiene, seeking prompt dental care when issues arise, and following your dentist's recommendations, you can address and prevent many common dental crown problems. Regular communication with your dentist is the key to ensuring the longevity and success of your dental crown.
