How long will a dental crown last?

The lifespan of a dental crown can vary widely depending on several factors, including the material used, the location of the crown in the mouth, and the patient's oral hygiene habits. However, on average, a well-made and well-maintained dental crown can last anywhere from 5 to 15 years. Here are some factors that can affect the lifespan of a dental crown:

1. Material: The material used to make the crown plays a significant role in its durability and longevity. Some materials, such as porcelain-fused-to-metal (PFM) crowns and all-ceramic crowns, tend to last longer than other materials like acrylic or composite resin crowns.

2. Location: The location of the crown in the mouth also affects its lifespan. Crowns placed in areas with high bite forces, such as the back molars, may experience more wear and tear compared to crowns placed in less stressful areas, such as the front teeth.

3. Oral Hygiene: Proper oral hygiene is essential for the longevity of dental crowns. Regular brushing, flossing, and avoiding biting hard objects can help prevent damage to the crown and keep it in good condition.

4. Bruxism: Patients who grind their teeth or clench their jaws (known as bruxism) may experience more wear on their crowns. Bruxism can put excessive pressure on the crown, leading to chipping or cracking.

5. Underlying Dental Issues: If the tooth underneath the crown has ongoing problems, such as recurrent decay or root canal issues, it can affect the crown's lifespan.

To extend the lifespan of a dental crown, it's important to maintain good oral hygiene practices, avoid biting hard objects, and address underlying dental issues promptly. Regular dental checkups and professional cleanings can also help ensure the crown remains in good condition. If a crown becomes damaged or worn, it's important to see a dentist for assessment and repair or replacement.
