Dental Crown Procedure
Different types of Dental Crown
Dental crowns are tooth-shaped caps that cover and protect damaged or decayed teeth. They can improve the function and appearance of the teeth and last for many years with proper care. However, there are different types of dental crowns, each made from different materials and serving various purposes. Some of the most common types of dental crowns are:
Metal crowns: These are made from gold, silver, or other alloys and are very durable and resistant to wear and tear. They can withstand high biting and chewing forces and rarely chip or break. However, they have a metallic color that may not match the natural teeth and may be more noticeable. They are usually used for back teeth that are not very visible.
Porcelain-fused-to-metal (PFM) crowns: These are made from a metal base with a porcelain layer on top. They combine the strength of metal with the aesthetics of porcelain and can match the color and shape of the natural teeth. However, they may wear down the opposing teeth and the metal may show through the porcelain over time. They are suitable for both front and back teeth.
All-ceramic or all-porcelain crowns: These are made entirely from ceramic or porcelain and have the most natural-looking appearance. They can mimic the translucency and color of the natural teeth and are biocompatible and hypoallergenic. However, they are more prone to chipping or cracking and may not be as strong as metal or PFM crowns. They are ideal for front teeth and for people with metal allergies.
Zirconia crowns: These are made from zirconium dioxide, a type of ceramic that is very strong and durable. They can withstand high biting and chewing forces and are less likely to chip or break. They also have a natural-looking appearance and can match the color and shape of the natural teeth. However, they may require more tooth preparation and may wear down the opposing teeth. They are suitable for both front and back teeth.
Composite resin crowns: These are made from a resin-based material that is tooth-colored and can be easily shaped and bonded to the tooth. They are less expensive and less invasive than other types of crowns and can be done in one visit. However, they are more susceptible to staining, discoloration, and wear and tear and may not last as long as other types of crowns. They are usually used for temporary or cosmetic purposes.
The type of dental crown that is best for each patient depends on several factors, such as the location, condition, and function of the tooth, the cost and availability of the material, and the preference and expectation of the patient. The dentist will evaluate the patient's oral health and discuss the pros and cons of each type of crown before recommending the most suitable option.
Dental Crown Recovery & Aftercare
The recovery period after getting a dental crown is typically a few days, during which some pain, discomfort, and sensitivity may occur. These symptoms can be managed with over-the-counter painkillers, such as ibuprofen, and topical anesthetic gels. It is also advisable to avoid hot or cold foods and drinks, as well as sticky or hard foods until the crown is fully set and the inflammation subsides.
To care for the dental crown and the surrounding gums, it is important to maintain good oral hygiene habits, such as brushing twice a day, flossing daily, and using mouthwash. However, care should be taken not to dislodge the crown or irritate the gums when flossing around the crowned tooth. A toothpaste for sensitive teeth may also help to reduce the sensitivity of the crown.
Additionally, some bad habits should be avoided to prevent damaging the crown or the underlying tooth, such as biting on nails, chewing on ice, opening bottles with teeth, or grinding teeth. If these habits are difficult to quit, a dentist may recommend wearing a mouth guard or a splint to protect the teeth and the crowns.
Patients should attend regular dental check-ups and follow-up appointments to monitor the condition of the crown and the tooth and to detect and treat any potential problems, such as cracks, decay, or infection. A dental crown can last for 10 to 15 years or longer, depending on the material, the quality of the placement, and the oral care of the patient.
