If you have a tooth or teeth that are heavily filled, broken down, in a weakened state or even just unsightly, porcelain crowns may be an option for you. A crown protects the structure of your tooth, by strengthening it with a tooth coloured ceramic or metallic ‘cap’. Molar and premolar teeth that have undergone endodontic (root canal) treatment are also recommended for porcelain crowns as they may be more prone to fracture following this treatment.
At CDIC, we recommend that a tooth with a restoration (filling) that comprises 50 percent or more of the overall tooth structure be considered for a crown. Too often we see patients presenting to us for the first time with either a broken or ‘lost’ crown. Following careful inspection we believe that this happens when the tooth is left too long before crowning, or the original filling size was too large. It’s quite simple, an important factor contributing to the strength of a crown is the amount of natural tooth remaining……. so the answer is – DONT WAIT TOO LONG BEFORE CONSIDERING A CROWN FOR THAT HEAVILY FILLED TOOTH.
Benefits of Porcelain Crowns
- Strength – Considered a dental restoration, crowns support the function of your teeth by covering the entire surface of your tooth.
- Rebuilding – A tooth protected with a porcelain crown restores the natural shape and feel of your mouth. Form and function are restored to your tooth.
- Appearance –Porcelain crowns can significantly enhance your smile – a minor change can make a marked improvement in the shape and colour of your teeth.
Teeth that are to be crowned require careful assessment. It is imperative to rule out any decay or nerve problems as well as examine the periodontal (gum health) status of the tooth. It may also be recommended that a tooth be assessed by an Endodontist (root canal specialist) prior to crowning to ensure that every effort has been exhausted to rule out future problems with the tooth.
Where a tooth to be crowned has part of its filling material below the ‘gumline’, it may also be recommended that the tooth undergo a ‘Crown Lengthening’ procedure and short healing period before the tooth is prepared for its crown.
