A dental crown is a common restorative treatment used to repair teeth that are damaged, decayed, or weakened. Often referred to as a “cap,” a crown covers the entire visible portion of a tooth, restoring its original shape, size, and function. This procedure is one of the most effective ways to save a natural tooth that might otherwise need to be extracted.
Understanding the process of getting a dental crown can help ease any anxiety about the procedure. Whether you are dealing with a large cavity, a cracked tooth, or cosmetic concerns, a crown provides a durable and long-lasting solution. This article explores everything you need to know about dental crowns, from the materials used to the steps involved in the procedure.
Common Reasons for Needing a Dental Crown
Dentists recommend crowns for several reasons, primarily focusing on protection and restoration. If a tooth has a large filling that is failing, a crown can provide the necessary support that the remaining tooth structure lacks. It effectively holds the tooth together and prevents further fracturing.
Crowns are also used to protect teeth that have undergone root canal therapy. After a root canal, the tooth often becomes brittle and prone to breaking. Placing a crown ensures the tooth remains functional and protected from the pressure of chewing. Other common reasons include:
- Restoring a tooth that is already broken or severely worn down.
- Covering a dental implant to replace a missing tooth.
- Improving the appearance of misshapen or severely discolored teeth.
- Holding a dental bridge in place to fill gaps in the smile.
Types of Dental Crown Materials
There are several materials used to create dental crowns, each offering different benefits depending on the location of the tooth and your specific needs. Your dentist will help you choose the best option based on durability, aesthetics, and cost.
1. All-Ceramic or Porcelain Crowns
These are the most popular choice for front teeth because they provide the best natural color match. They are made entirely of ceramic material and are a great option for patients with metal allergies. While highly aesthetic, they may be slightly less durable than metal-based options for back molars.
2. Porcelain-Fused-to-Metal (PFM)
PFM crowns consist of a metal substructure with a porcelain layer baked over it. They offer a strong bond and high durability while still looking like a natural tooth. However, the metal underneath can sometimes show through as a dark line at the gum level over time.
3. Zirconia Crowns
Zirconia is a type of crystal that is exceptionally strong and long-lasting. These crowns are becoming increasingly popular because they can withstand heavy biting forces. They are an excellent choice for back teeth and offer a good balance between strength and appearance.
4. Metal and Gold Alloys
Metal crowns are made from alloys containing gold, platinum, or base metals like nickel-chromium. These are the most durable and require the least amount of tooth structure to be removed. Because of their metallic color, they are typically reserved for molars that are not visible when you smile.
The Dental Crown Procedure: Step-by-Step
Getting a dental crown usually requires two separate appointments. The first visit involves preparing the tooth, while the second visit involves placing the permanent restoration. Modern technology, such as CAD/CAM, sometimes allows for “same-day” crowns, but the two-visit process remains the standard.
Step 1: Examination and Preparation
During the first visit, your dentist will take X-rays to check the roots of the tooth and the surrounding bone. If there is extensive decay or risk of infection, a root canal might be performed first. The dentist will then numb the area and reshape the tooth to make room for the crown.
Step 2: Taking Impressions
Once the tooth is reshaped, your dentist will take an impression of the tooth using a paste or a digital scanner. This mold is sent to a dental laboratory where the permanent crown is custom-made. This process usually takes two to three weeks.
Step 3: The Temporary Crown
Because your tooth has been reshaped, it will be sensitive and vulnerable while you wait for the permanent crown. Your dentist will place a temporary crown made of acrylic or composite resin. This is held in place with temporary cement so it can be easily removed later.
Step 4: Placing the Permanent Crown
At the second appointment, the temporary crown is removed, and the dentist checks the fit and color of the permanent crown. If everything looks correct, the crown is permanently bonded to the tooth using dental cement. The dentist will make final adjustments to ensure your bite feels natural.
Recovery and Aftercare
The recovery process for a dental crown is usually very quick. You may experience some sensitivity to hot and cold temperatures or minor gum soreness for a few days after the procedure. Over-the-counter pain relief is typically sufficient to manage any discomfort.
To ensure your crown lasts as long as possible, it is important to maintain good oral hygiene. While the crown itself cannot decay, the tooth underneath and the surrounding gum line are still susceptible to disease. Follow these tips for long-term care:
- Brush your teeth twice a day with fluoride toothpaste.
- Floss daily, paying extra attention to the area where the crown meets the gum.
- Avoid biting down on hard objects like ice, popcorn kernels, or hard candy.
- Wear a nightguard if you have a habit of grinding your teeth (bruxism).
- Visit your dentist regularly for professional cleanings and check-ups.
How Much Do Dental Crowns Cost?
The cost of a dental crown varies widely based on the material used and the geographic location of the dental office. On average, you can expect to pay between $800 and $1,500 per tooth. Metal and PFM crowns are often on the lower end, while all-ceramic and zirconia crowns tend to be more expensive.
Many dental insurance plans cover a portion of the cost, especially if the crown is medically necessary to save a tooth. It is always a good idea to contact your insurance provider beforehand to understand your coverage and out-of-pocket expenses.
Conclusion
Dental crowns are a highly effective and versatile solution for restoring damaged teeth. By choosing the right material and following a consistent oral care routine, your crown can last between 10 and 15 years, or even longer. If you have a tooth that is causing pain or looks damaged, consult with your dentist to see if a crown is the right solution for you.
