When a cavity gets too large, regular dental fillings cannot predictably fill the defect created by the cavity and is prone to failure. In these situations, crowns are the treatment of choice as it offers excellent predictability by completely covering the tooth.
Unlike fillings, which can leave thin corners in your teeth that are prone to fractures, a dental crown completely covers the tooth. This makes dental crowns a great solution to replacing damaged or compromised teeth.
Dental crowns can also be used for cosmetic purposes. These caps can add structure and mass to uneven or short teeth and improve the appearance of your smile.
If you are in the habit of grinding your teeth, consuming acidic food items, or have health problems like GERD and bulimia, your teeth will face a considerable amount of wear and tear. These problems can remove the enamel on your teeth and make them more vulnerable to decay. Dental crowns will protect worn down teeth and minimize the damage.
Like a large filling, the root canal also weakens the structure of the tooth. Dentists will remove the top portion of your tooth to access the nerve underneath and remove it. They will apply a dental crown over the exposed root to protect it and rebuild its structure.
