It is critical for patients to practice good oral hygiene in order to avoid serious oral health issues. When patients avoid visiting the dentist for routine cleanings and examinations, minor issues can quickly become more serious. The failure to fill a cavity can allow for it to get progressively worse. Over time, it can result in the need for a dental crown or even result in tooth loss. The dentist may also suggest a dental crown in the event the tooth is damaged or compromised.
Crowns are a common treatment used in dentistry to restore the function of a tooth. The crown is essentially a cap which is placed over the natural tooth. When a tooth has a minor cavity or damage, the dentist will often use a filling. In cases where the issue is too large or the damage is more severe, a crown is often recommended.
A crown will fit securely over the tooth and is specially designed to match the shape and color of the natural tooth. Crowns can restore the tooth’s size, shape, strength and overall appearance. Prior to receiving a crown, the dentist will obtain an impression of the tooth. The impression will typically be sent to the lab where the crown is being created.
A temporary crown is often placed while the permanent crown is created. When the permanent crown is ready, the temporary crown is removed. The dentist will ensure the crown fits properly and make any adjustments before cementing it in place. The crown covers the surface of the tooth above the gums and provides added strength.
Lifespan of a Dental Crown
While a dental crown likely will not last a lifetime for the patient, they can last for up to 30 years with proper care. A gold crown can last for a very long time. Unfortunately, they are very expensive and not commonly used. The dentist will typically recommend a dental crown in order to restore the appearance of a tooth or preserve the tooth’s function.
Over time, the crown will weaken and be damaged from regular wear and tear. In addition, patients who consume hard, crunchy foods may be at a higher risk for damage. Various factors such as the patient’s diet and oral hygiene can impact the expected lifespan of their crown.
In order to maximize the lifespan of a dental crown it is extremely important for patients to practice good oral hygiene with daily brushing and flossing. Patients should also avoid consuming hard or sticky foods like nuts and caramel. It is also helpful for patients to wear a night guard to protect the crown from clenching and grinding while the patient is sleeping. Some patients who grind their teeth are not even aware of the habit until the dentist brings it to their attention. The dentist can create a custom night guard which is extremely durable, but they can also be purchased over the counter at many drugstores.
The placement of the crown can also largely impact how much damage or wear and tear it will endure. Teeth in the back of the mouth, for example, absorb a majority of the forces from chewing. As a result, the crown will experience more wear compared to a crown placed on a tooth located in the front of the mouth. Crowns which are properly cared for and do not experience significant wear and tear can last a lifetime.
On average, most crowns can be expected to last anywhere from 10–30 years after they are placed. Patients must practice good oral hygiene with at least twice daily brushing and daily flossing. Regular visits to the dentist also ensure the crown is in good condition and identifies any issues which could compromise the restoration. Patients can also prolong the lifespan of the crown by avoiding crunchy foods.
