If a tooth is broken, cracked, or damaged, the ability of the enamel and crown to protect the tooth is compromised. Dental crowns are needed in order to protect the inside of the tooth and seal out bacteria and food particles. Otherwise, the tooth is vulnerable to infection and decay, and eventual tooth loss or other dental emergency.
Dental crowns are often needed after root canal therapy, and are also used when creating a dental bridge, or are placed over a dental implant when replacing a tooth. Dental crowns are also used as an alternative to dental veneers when correcting issues such as broken or chipped teeth.
What are the steps involved in a Dental Crown?
If the dental crown will be placed over your original tooth, such as with dental bridges and root canals, the tooth or teeth must be prepared so that the crown can fit snugly on top of the tooth structure. Tooth preparation and the delivery of the permanent crown are usually done in two steps.
First, your dentist will numb the area to be treated with local anesthetic. Next, they will reshape the outside tooth by shaving and removing enough of the tooth material to allow the crown to sit on top and fit with the rest of your teeth. Once this process is complete, your dentist will take an impression of your teeth, which will be sent to a dental laboratory where a permanent crown will be created to match your smile. Your dentist will create and place a temporary crown to seal and protect the tooth temporarily until your permanent crown is ready for placement.
During the placement of the permanent crown, your dentist will remove the temporary crown, ensure the prepared tooth is clean, and place the permanent crown over the prepared tooth. Your dentist may need to make adjustments to ensure your crown fits and feels natural in your mouth before permanently cementing the crown into place.
Dental Crowns for Children
Sometimes, following a [pulpotomy] procedure, also known as a root canal for a baby tooth, the dentist may recommend placement of a stainless steel or tooth-colored crown to protect the tooth from further damage or decay.
Types of dental crowns:
Metal Crown: The most basic type of crowns. Offers good protection of tooth, but does not look good due to metal which is visible in mouth.
Porcelin Fused to Metal(PFM): Over the metal substructure, porcelin(a type of biocompatible glass) is fused to give the crown- tooth like appearance and colour.
Zirconia Crowns:Hardest material, a zirconia crown is a tooth coloured material from which crowns are made, it has ZERO Metal and is totally METAL FREE. It has great advantage over all other crowns- being strongest and most kind to gums- a warranty will be provided for its breakage. Moreover Zirconia crowns are MRI safe.
Post Procedure & Aftercare for Dental Crowns
Dental crowns are designed to be strong and should last many years with proper care and maintenance. That means brushing for two minutes, twice per day and flossing at least once every day, taking care to avoid very hard or sticky foods, which can damage or break dental crowns and regular teeth as well. Another critical step in your maintenance routine for your dental crown and overall oral health is to visit Fresh Smiles for regular checkups and cleanings every 6 months.
