A dental crown is often called a “cap.” A dental crown covers all of the visible parts of the tooth and has many functions and reasons for placement.

There are several different types of crowns available at Robson Dentistry. They vary in their material, appearance, and functionality. A PFM, or porcelain fused to high-noble metal, is the most common. A full cast, high noble metal crown is a gold crown, and a stainless-steel crown is meant to be temporary. The most natural-looking crown is one that is all porcelain. These are often used for front teeth.

Getting a crown typically requires two appointments. The first is a preparation with impressions, shaping, and placing a temporary. The impressions are either sent to a dental lab, where the process generally takes two weeks, or done in-office with a machine that can make a crown without needing a second appointment. These crowns are made from a high-quality solid block of porcelain. The shape of the tooth is constructed from a digital 3D image of your tooth.

To accurately determine which type of crown is best, you must first know why you need the crown and in what area of your mouth is it needed, which can be answered when you visit us at Robson Dentistry. For instance, if you have a gold crown on the lower right and need a new crown directly above on the upper right, the best durability and long-lasting relationship is another gold crown.

If you need a crown on a front tooth, a gold crown may not be the best choice. A PFM has strength but is not ideal, as a dark line will appear at the gum line. A full porcelain crown is going to look as close to a natural tooth as possible, but will have less strength than a gold crown.

There are two types of porcelain crowns, depending on how they are made. A dental lab makes a full porcelain crown by baking layer upon layer to make the porcelain look like natural enamel. A full porcelain crown made in-office out of a solid piece of porcelain will have increased strength. However, the natural layered appearance is extremely difficult to achieve.

A crown is placed on a tooth when added strength is needed. Cracks, large broken-down fillings, or previous root canal treatment are all conditions where a crown is the standard care. The type of crown that is most appropriate depends greatly on location.

Did you know the month of May is designated National Physical Fitness and Sports Month? After all, there isn't a better time to celebrate physical activity as when the warm weather and sunshine makes its way back into our lives!

Now that the flowers are in bloom and the weather has warmed up, it's easier to go outside and soak up the sun. After spending the winter working out in gyms or doing crunches at home, exercising outdoors can be a lot more enjoyable as well. Whether you enjoy hikes, jogging, or biking, spring gives us a chance to smell the grass, take in the rays, and enjoy the blue sky—all senses that we just can't duplicate at the gym.

If jogging or biking isn't your cup of tea, we encourage you to try a sport! Sports have some amazing qualities that we often overlook. Team sports like baseball and soccer, and individual sports like golf and tennis can improve your coordination and agility, in addition to building determination, confidence, drive, hard-work, pride, leadership, and time management.

At Robson Dentistry, we always encourage our patients to stay fit by exercising or participating in sports. However, we want to remind you to always wear a mouthguard or other form of facial protection when playing sports. To learn more about how often your child should exercise, or to ask us about obtaining a mouthguard, please give us a call!

When a child is born, he or she will have 20 primary teeth and 32 permanent teeth. But sometimes kids are born with additional teeth, and our team at Robson Dentistry call this oral condition "hyperdontia." Primary teeth are the first set of teeth that erupt in your child's mouth, typically by the time they are 36 months old, and are shed by the time your child reaches the age of 12. Permanent teeth then take the place of the primary teeth and are usually fully-erupted by the time your son or daughter reaches 21 years of age. Anyone who develops more than 20 primary teeth or more than 32 permanent teeth has hyperdontia, and the additional teeth are referred to as supernumerary teeth.

While the cause of hyperdontia is not entirely clear, it is believed that there may be a genetic factor. Oral professionals have found that patients with extra teeth often have syndromes like cleidocranial dysplasia, Ehler-Danlos syndrome, Gardner syndrome, or cleft lip and palate. The prevalence of hyperdontia affects between one and four percent of the population in the United States, and the majority of cases are limited to a single tooth.

So, what is the best way to deal with hyperdontia? It really depends on the case. The treatment plan your doctor suggests varies according to the potential problem posed by the supernumerary teeth, as well as their type. Orthodontic treatment may certainly may help, but extraction can also be a good option. We recommend that children receive an oral evaluation or checkup no later than the age of seven. In addition to hygiene evaluation, this helps ensure your child does not experience hyperdontia problems.

If you suspect you or your child may be suffering from hyperdontia, please give us a call to schedule an appointment at our convenient East Lyme, CT office to be evaluated.
