Dental crowns are restorations that fully encase a damaged or weakened tooth to restore its shape, size, strength, and appearance. They are commonly recommended when a tooth has been significantly weakened by decay, fractures, large fillings, or after a root canal treatment. Crowns can also be used for cosmetic improvements, covering misshapen or severely discolored teeth. By providing full coverage, crowns help protect the tooth from further damage while preserving its function.
At Jowett & Lewis Family Dentistry in Topeka, KS, Dr. Andrew Lewis and Dr. Ted A. Jowett carefully assess each patient’s needs to determine if a dental crown is the best solution. Whether the goal is restoring function or enhancing aesthetics, understanding the reasons behind crown placement helps patients feel more confident about their treatment plans.
Preparing for Your Dental Crown: Initial Steps
The dental crown process typically begins with a comprehensive evaluation. During this visit, your dentist will examine the affected tooth and take X-rays to assess its health and the surrounding bone structure. If extensive decay or infection is found, additional treatments like root canal therapy may be needed before crown placement. Once the tooth is ready, the preparation process begins.
The tooth is first reshaped to create enough space for the crown to fit securely. This may involve removing a portion of the outer tooth structure. In cases where significant portions of the tooth are missing, a filling material may be used to build up the tooth and provide a solid foundation for the crown. An impression is then taken of the prepared tooth and the surrounding teeth to ensure a precise fit. At Jowett & Lewis Family Dentistry, advanced digital scanning technology is often used to improve accuracy and patient comfort during this step.
Temporary Crowns: Their Purpose and Care
While the final crown is being fabricated in a dental lab—a process that typically takes two to three weeks—a temporary crown is placed to protect the prepared tooth. Temporary crowns are usually made of acrylic or composite material and are designed to be easily removable. They help maintain tooth function, appearance, and comfort during the interim period.
Caring for a temporary crown requires some caution. Patients are advised to avoid sticky or hard foods that could dislodge or damage the temporary crown. Gentle brushing and flossing around the crown are important to maintain gum health and prevent infection. Dr. Lewis and Dr. Jowett provide detailed care instructions to ensure the temporary crown remains intact and functional until the final restoration is ready.
Placing the Permanent Crown: Final Steps
Once the permanent crown is ready, you will return for a second appointment to have it placed. The dentist first removes the temporary crown and cleans the tooth thoroughly. The fit and color of the new crown are checked carefully to ensure it blends seamlessly with the natural teeth. Adjustments may be made to the crown’s shape to achieve proper alignment and bite function.
When everything is satisfactory, the crown is permanently cemented into place. Strong dental adhesives are used to ensure a durable and secure bond. The final result should feel natural and comfortable, restoring the tooth’s appearance and function. Patients at Jowett & Lewis Family Dentistry often report feeling immediate relief and satisfaction once the permanent crown is in place, thanks to the attention to detail Dr. Lewis and Dr. Jowett bring to every procedure.
Common Materials Used for Dental Crowns
Dental crowns can be made from several different materials, each offering specific benefits. Common options include:
- Porcelain or Ceramic:
These crowns provide the best color match to natural teeth and are ideal for front teeth. - Metal (Gold, Platinum, or Base Metal Alloys):
Metal crowns are highly durable and are often used for out-of-sight molars due to their strength and longevity. - Porcelain-Fused-to-Metal (PFM):
These crowns combine the aesthetics of porcelain with the strength of a metal base, offering a good balance for many patients. - All-Resin:
Resin crowns are less expensive but wear down faster and are more prone to fractures.
At Jowett & Lewis Family Dentistry, material selection is discussed thoroughly with each patient to ensure the crown aligns with their needs, preferences, and budget.
Caring for Your Dental Crown After Placement
With proper care, dental crowns can last 10 to 15 years or even longer. Good oral hygiene is crucial to protecting the crowned tooth and the surrounding gums. Patients should brush their teeth twice daily with a fluoride toothpaste, floss daily (especially around the crown), and attend regular dental checkups and cleanings.
It is also advisable to avoid habits like biting fingernails, chewing ice, or grinding teeth, as these behaviors can damage crowns. For patients who grind their teeth at night, Dr. Lewis and Dr. Jowett may recommend a custom nightguard to protect both natural teeth and restorations. Consistent care and preventive measures can extend the life of a crown and support overall oral health.
