All crowns are designed to restore functionality to a damaged tooth. But crowns can differ from one another in their appearance, in the material they’re made from, and how they blend with other teeth.
A crown is a metal or porcelain artifice that’s bonded permanently over a decayed or damaged tooth. Every crown process begins with preparation of the tooth so the crown will fit over it. Afterward, we make an impression of the prepared tooth digitally or with an elastic material that most often is sent to a dental laboratory to create the new crown.
It’s at this point where crown composition and design can diverge. Most of the first known crowns were made of metal (usually gold or silver), which is still a component in some crowns today. A few decades ago dental porcelain, a form of ceramic that could provide a tooth-like appearance, began to emerge as a crown material. The first types of porcelain could match a real tooth’s color or texture, but were brittle and didn’t hold up well to biting forces. Dentists developed a crown with a metal interior for strength and a fused outside layer of porcelain for appearance.
This hybrid became the crown design of choice up until the last decade. It is being overtaken, though, by all-ceramic crowns made with new forms of more durable porcelain, some strengthened with a material known as Lucite. Today, only about 40% of crowns installed annually are the metal-porcelain hybrid, while all-porcelain crowns are growing in popularity.
Of course, these newer porcelain crowns and the attention to the artistic detail they require are often more expensive than more traditional crowns. If you depend on dental insurance to help with your dental care costs, you may find your policy maximum benefit for these newer type crowns won’t cover the costs.
If you want the most affordable price and are satisfied primarily with restored function, a basic crown is still a viable choice. If, however, you would like a crown that does the most for your smile, you may want to consider one with newer, stronger porcelain and made with greater artistic detail by the dental technician. In either case, the crown you receive will restore lost function and provide some degree of improvement to the appearance of a damaged tooth.
When is the best time to floss your teeth: Morning? Bedtime? How about: whenever and wherever the moment feels right?
For Cam Newton, award-winning NFL quarterback for the Carolina Panthers, the answer is clearly the latter. During the third quarter of the 2016 season-opener between his team and the Denver Broncos, TV cameras focused on Newton as he sat on the bench. The 2015 MVP was clearly seen stretching a string of dental floss between his index fingers and taking care of some dental hygiene business… and thereby creating a minor storm on the internet.
Inappropriate? We don't think so. As dentists, we're always happy when someone comes along to remind people how important it is to floss. And when that person has a million-dollar smile like Cam Newton's — so much the better.
Of course, there has been a lot of discussion lately about flossing. News outlets have gleefully reported that there's a lack of hard evidence at present to show that flossing is effective. But we would like to point out that, as the saying goes, “Absence of evidence is not evidence of absence.” There are a number of reasons why health care organizations like the American Dental Association (ADA) still firmly recommend daily flossing. Here are a few:
- It's well established that when plaque is allowed to build up on teeth, tooth decay and gum disease are bound to follow.
- A tooth brush does a good job of cleaning most tooth surfaces, but it can't reach into spaces between teeth.
- Cleaning between teeth (interdental cleaning) has been shown to remove plaque and food debris from these hard-to-reach spaces.
- Dental floss isn't the only method for interdental cleaning… but it is recognized by dentists as the best way, and is an excellent method for doing this at home — or anywhere else!
Whether you use dental floss or another type of interdental cleaner is up to you. But the ADA stands by its recommendations for maintaining good oral health: Brush twice a day for two minutes with fluoride toothpaste; visit your dentist regularly for professional cleanings and checkups; and clean between teeth once a day with an interdental cleaner like floss. It doesn't matter if you do it in your own home, or on the sidelines of an NFL game… as long as you do it!
In an instant, an accident could leave you or a loved one with a missing tooth. Thankfully, we can restore it with a dental implant that looks and functions like a real tooth—and the sooner the better.
But if the patient is a teenager or younger, sooner may have to be later. Because their jaws are still developing, an implant placed now could eventually look as if it's sinking into the gums as the jaw continues to grow and the implant doesn't move. It's best to wait until full jaw maturity around early adulthood and in the meantime use a temporary replacement.
But that wait could pose a problem with bone health. As living tissue, bone cells have a life cycle where they form, function and then dissolve (resorption) with new cells taking their place. This cycle continues at a healthy rate thanks to stimulation from forces generated by the teeth during chewing that travel through the roots to the bone.
When a tooth goes missing, however, so does this stimulation. Without it the bone's growth cycle can slow to an unhealthy rate, ultimately reducing bone volume. Because implants require a certain amount of bone for proper placement and support, this could make it difficult if not impossible to install one.
We can help prevent this by placing a bone graft immediately after the removal of a tooth within the tooth's "socket." The graft serves as a scaffold for new bone cells to form and grow upon. The graft will eventually resorb leaving the newly formed bone in its place.
We can also fine-tune and slow the graft's resorption rate. This may be preferable for a younger patient with years to go before their permanent restoration. In the meantime, you can still proceed with other dental treatments including orthodontics.
By carefully monitoring a young patient's bone health and other aspects of their dental care, we can keep on course for an eventual permanent restoration. With the advances in implantology, the final smile result will be worth the wait.
