Crown & Bridges

Crown and BridgesSmiles On Don Mills Dentist in North York offers a number of options to restore teeth that have been damaged or lost. Your dentist can determine which ones best meet your needs.

Crowns strengthen damaged teeth, allowing them to function normally again. Porcelain crowns like Zirconia crowns are virtually indistinguishable from natural teeth. There are other materials besides porcelain that can be used to make dental crowns, such as all-metal crowns or porcelain-fused-to-metal crowns (PFM). Our dentists would be happy to discuss the pros and cons of these various options with you.

Crown & BridgesChances are you talk to people who have crowns or bridgework every single day and don’t even realize it. Dental crowns and bridges are designed to look just like your natural teeth and are of the most common ways to restore a single tooth or several teeth. It’s easiest to think of a crown as a “cap” that fits over a damaged, decayed, or unattractive tooth, completely covering the tooth above the gum line. This is different from a veneer, which covers only a tooth’s front surface and needs natural tooth structure to support it. If a tooth is missing a significant amount of structure above the gum line, a crown is the restoration of choice.

Crowning or Capping a Tooth

Crowning or Capping a Tooth

Crowning or capping a tooth usually takes at least two visits. At the first visit, we will prepare your tooth to receive its new crown. First we will shape it to fit inside the new covering. This will involve some drilling to give the tooth a uniform shape. We will numb the tooth and the surrounding area beforehand. If you have very little tooth structure to begin with, we may have to build up the tooth with filling material, rather than remove tooth structure, to support the crown. This is commonly referred to as a core build-up.

After the tooth is prepared, we will take impressions of your teeth with reliable, putty-like impression materials, and send them to the dental laboratory. There, the impressions will be used to make models of your teeth for the creation of the new crown. The models will serve as guides to the highly-skilled lab technicians who will ensure that your new crown is designed to enhance your smile and function will within your bite. Before you leave the office, we will attach a temporary crown to your tooth to protect it until the permanent crown is ready. At another visit, your permanent crown will be attached to your tooth with either a resin that hardens when exposed to a special light source, or a type of permanent cement.

Creating a Bridge

Creating a Bridge

Crowns can also be used to create a realistic replacement for a missing tooth. This is done with bridgework, which spans the space of the missing tooth and requires at least three crowns. Two of those crowns will be placed over healthy teeth on either side of the missing tooth; these healthy teeth are called abutment teeth. The two crowned abutment teeth become supports for a third crown placed in between; that third crown is called a pontic. If more than one tooth is missing, more crowns will be needed to bridge the gap between the abutment teeth.

The number of abutment teeth necessary to replace missing teeth is determined by the number of missing teeth, the size and length of the abutment tooth roots, the amount of bone support each abutment tooth has, as well as where in the mouth the missing tooth is located. For example, if you have three missing teeth, four abutment teeth may be necessary, thereby creating a seven-tooth bridge. Your dentist will determine the type of bridge you need to achieve a beautiful and healthy smile.

Caring for Your Crowns & Bridgework

Just as you do with natural teeth, you’ll need to be sure to brush and floss your crowns and bridgework every day to reduce the buildup of dental plaque. Avoid using your teeth to open packages or to break thread, and if you grind your teeth, you may want to invest in a night guard to protect your dental work. Smiles On Don Mills Dental is proud to provide a warranty for all crown and bridge work by any of our dentists. However, the warranty coverage requires regular scheduled visits and compliance. Please ask us for details. Together, we’ll make sure your crowns and bridgework last a long time.
