If you believe you need a crown or if we have already confirmed this fact, you need to understand that there are several options. The most common are gold crowns, porcelain-fused-to-metal crowns and all porcelain crowns. Each has both pros and cons; thus we will work with you to determine which will work best for your specific needs. However, to help you learn more now, here are some facts.
Made from cast gold, this type of crown has been around for over 100 years and is the most successful type of crown. It can last more than 50 years and thus many dentists prefer gold restorations for their own teeth, where cosmetics is not a concern.
All Porcelain Crowns
All porcelain crowns can produce an incredible, life-like appearance. However, because they are made purely from dental porcelain (a type of glass), they tend to be more fragile than gold crowns and may be more at risk with certain high biting forces. Thus they may not be as durable. Porcelain can also cause wear to the natural teeth they bite against. Therefore they are typically preferred for front teeth, rather than back teeth. They have an aesthetic longevity of about 10 years and a functional longevity of about 20 years.
As the name states, porcelain-fused-to-metal (PFM) crowns provide the best of both worlds. They are made of natural tooth-colored dental porcelain that is fused on top of a precious or noble metal (usually gold or platinum). They are stronger than porcelain alone and are a good option for back teeth because they offer a better cosmetic result than gold crowns. This is also true for front teeth, however the gold support beneath the porcelain can compromise its life-like qualities. These crowns also have a proven track record and have been used with excellent results for over 40 years.
When it comes to sports, all athletes need to know how to assess their risk for experiencing a sports-related injury as well as how to prevent one. The first step to accomplish this is learning how sports and activities are classified, as they define risks from little-to-no chance of injury to highly susceptible for injuries. These categories include:
- Low velocity, non-contact sports: These sports and activities have the lowest risk, as they typically include sports where the athletes perform individually at reasonable speed without physical contact. Examples include: golf, Nordic skiing, weight lifting, running and swimming.
- High velocity, non-contact sports: These sports and activities are those where athletes move at high rates of speed but with no contact with other participants. While there is no contact, anytime you are moving at high rates of speed, accidents can happen. Examples include: bicycling, motocross, skateboarding, skiing and snowboarding.
- Contact sports: As the title states, these sports and activities include frequent body-to-body contact or body to equipment (e.g., a ball, glove, etc.) contact. Examples include: basketball, soccer, lacrosse, baseball and softball.
- Collision sports: With these sports and activities, strong, forceful, body-to-body or body-to-equipment contact is a primary goal of the sport. Examples include football, ice hockey, rugby, and boxing. Without the proper protective head and mouth gear, participants are highly likely to experience an oral-facial and/or head injury.
The good news is that you can dramatically reduce the odds of serious dental and oral-facial injury by ensuring that you wear a professionally made mouthguard in addition to a helmet, facemask, or other protective gear that is appropriate to the sport. This is especially true if you participate in the high velocity, contact and collision categories. These simple steps can help reduce worries for not only players, but also for parents, caregivers and coaches.

Losing a baby tooth is an important milestone in a child's life. Be sure to take a photo of that toothless smile — it will be something you treasure as your child grows up.
You may be wondering what is really happening when a baby tooth becomes loose and eventually falls or is pulled out. Read on for some answers.
What are baby teeth?
An infant's teeth begin to form before birth, by the fifth to sixth week after conception. When the baby is born, 20 primary (baby) teeth are almost completely formed inside the jaws. These first teeth, also called deciduous teeth, begin to erupt through the gums at about the time the baby begins to eat solid food. The front teeth (incisors) are usually the first to come in, at age six months to a year.
Why are they called deciduous teeth?
Deciduous means “falling off at maturity.” The same term refers to trees that lose their leaves every fall. In many mammals, including humans, it refers to the first teeth, which need to come out to make room for the larger permanent teeth to come in.
What causes the deciduous teeth to become loose?
While your child is using his primary teeth to bite and chew, his adult (permanent) teeth are quietly growing inside his jawbone. Starting with tooth “germs” (the word comes from germination, meaning the start of growth), the top part of each tooth, called the crown, grows first. Then the bottom part, or root, begins to grow and elongate. As the roots develop and the permanent teeth take up more room in the child's jaw, they begin to push against the baby teeth. This causes the roots of the baby teeth to melt away or resorb. Eventually little or nothing is left to hold the baby teeth inside the child's gums, they become wiggly, and finally they can easily be pulled out. This may leave a little bleeding gum tissue that quickly heals.
What should you watch for in the transition from primary to permanent teeth?
As the permanent teeth erupt (push through the gums and become visible), you may notice that they are too crowded, have too much space between them, or are crooked. It's a good idea to have an orthodontic (from ortho, meaning straight and dont, meaning tooth) evaluation at age five to seven. Watch to see that the baby teeth are lost in the right sequence. If one is lost prematurely, for example from decay, make sure that the space that it occupied is maintained to make room for the adult tooth that will replace it. We can help you with this.

The beloved title of “mother” unfortunately does not come with a manual. If it did, it would certainly contain a section in which mothers-to-be could learn about the impact that pregnancy has on both their general and oral health. For example, did you know that during pregnancy the normally elevated levels of female hormone progesterone can cause inflammation in blood vessels within the gum tissues making the gums bleed? It typically occurs in response to less than adequate daily oral hygiene; however, it is just one important fact that all pregnant women should know.
There are numerous studies that have revealed that oral health during pregnancy can have a significant impact on the child growing inside you, and in particular, it has a direct relationship on your baby's developing and future oral health.
Periodontal (gum) disease can also be a factor in your baby's birth weight. In fact, there are a variety of studies supporting a positive link between pre-term delivery and low birth weight babies in the presence of severe periodontal disease in pregnant women. And there is also a correlation between the severity of periodontal disease and the possibility of an increased rate of pre-eclampsia or high blood pressure during pregnancy. This is another reason why it is important to see a dentist for an evaluation of your oral and dental health as soon as you know you are pregnant.
Please note that the goal of sharing these facts is not to scare you, but rather inform you so that you can be an educated mother-to-be. After all, you should be as healthy as possible for the most important job in the world and this includes both your oral and general health.
