What is a dental crown?
A dental crown is a cap that is placed over a tooth to protect and restore it to its normal shape, size, and function. It is used to cover and support a tooth that has been damaged or is weakened, such as due to a large filling, root canal treatment, or tooth decay. A dental crown can also be used to improve the appearance of a tooth, for example by covering a discolored or misshapen tooth.
Dental crowns can be made of different materials, such as porcelain, ceramic, metal, or a combination of these materials. The type of material used will depend on the location and function of the tooth, as well as the patient’s preferences and needs. Porcelain or ceramic crowns are more natural looking and can be used for front teeth, while metal crowns are stronger and may be used for back teeth.
What is the process of getting a dental crown?
The process of getting a dental crown usually involves two visits to the dentist. During the first visit, the tooth is prepared and a mold is taken to create the crown. A temporary crown is placed over the prepared tooth until the permanent crown is ready. The permanent crown is then cemented in place at the second visit. A dental crown can last for many years with proper oral hygiene and regular dental check-ups.
What is the best material to use for a dental crown?
There are several types of materials that can be used to make dental crowns, and the best material for a particular patient will depend on a number of factors, including the location and function of the tooth, the patient’s preferences, and the cost. Here is a brief overview of some of the materials that are commonly used for dental crowns:
Porcelain or ceramic dental crowns
These materials are a good choice for front teeth because they look natural and can be color-matched to the patient’s other teeth. However, they may not be as strong as some of the other materials and may not be suitable for use on back teeth or in situations where the tooth is subjected to heavy biting or grinding forces.
Metal dental crowns
Metal crowns, such as gold or base metal alloys (e.g. nickel, chromium, or cobalt), are strong and durable and can be used on any tooth. They are a good choice for back teeth or for patients who grind their teeth. However, they may not be as natural looking as porcelain or ceramic crowns and may not be a good choice for front teeth.
Porcelain-fused-to-metal dental crowns
This type of crown combines the strength of metal with the natural-looking appearance of porcelain. The porcelain layer is fused to a metal underlay, which helps to make the crown stronger and more durable. These crowns can be used on any tooth and can be a good choice for patients who want a natural-looking crown that is also strong. However, the metal underlay may show through the porcelain if the gum tissue recedes, which can be a drawback for some patients.
Resin dental crowns
Resin crowns are made of a plastic material and are a less expensive option than other types of crowns. They are not as strong or durable as metal or porcelain crowns and are generally not recommended for use on back teeth or in situations where the tooth is subjected to heavy biting or grinding forces. However, they may be a good choice for temporary crowns or for patients who have allergies to metal.
The best material for a particular patient will depend on the specific needs and preferences of that patient. It’s important to discuss all of the options with a dentist and to consider factors such as the cost, the appearance, and the strength of the material before making a decision.
What’s the best dental crown for someone that grinds or clenches?
If you grind or clench your teeth (a condition known as bruxism), it’s important to choose a dental crown that is strong and durable to withstand the increased forces on your teeth. Metal crowns, such as gold or base metal alloys (e.g. nickel, chromium, or cobalt), are generally the most durable and are a good choice for patients who grind or clench their teeth. These crowns can withstand heavy biting and grinding forces and are less likely to break or chip compared to crowns made of other materials.
Another option for patients who grind or clench their teeth is a porcelain-fused-to-metal crown. These crowns combine the strength of metal with the natural-looking appearance of porcelain. The porcelain layer is fused to a metal underlay, which helps to make the crown stronger and more durable. These crowns can be used on any tooth and can be a good choice for patients who want a natural-looking crown that is also strong. However, the metal underlay may show through the porcelain if the gum tissue recedes, which can be a drawback for some patients.
It’s important to note that while metal crowns and porcelain-fused-to-metal crowns are generally the most durable options for patients who grind or clench their teeth, they may not be as natural-looking as other types of crowns. If you are concerned about the appearance of your crown, you should discuss your options with your dentist and consider other factors, such as the cost and the specific needs of your tooth.
