Dental crowns are caps placed on top of damaged teeth. Crowns are used to protect, cover and restore the shape of your teeth when fillings don’t solve the problem. Dental crowns can be made out of metals, porcelain, resin and ceramics. They typically don’t require special care over time other than regular good oral hygiene.
You may need a dental crown for several reasons, including:
Metal free crowns made of poly methyl methacrylate
Advantage: less expensive, as a temporary crown.
Disadvantage: shorter life, easily wear off.
Provide the best natural colour match compared to any other crown type.
Advantage: no metal allergy, excellent aesthetics and colour matching, longer life, strength as good as metal crown.
These dental crowns have a hard inner core.
Advantage: provides the best natural colour match, more long-lasting than an all-porcelain crown, excellent aesthetics for anterior teeth.
A crowned tooth doesn’t need any special care. However, the underlying tooth still needs to be protected from decay or gum disease. Because of this, you should continue to follow good oral hygiene practices. These practices include brushing your teeth twice a day and flossing once a day — especially around the crown area where the gum meets your tooth. Also, avoid biting on hard surfaces with porcelain crowns (for example, chewing ice or popcorn hulls) to prevent cracking the porcelain.
