If you've decided on a dental implant to replace a missing tooth, you've made a great choice. Implants are a big favorite of both dentists and patients, not only for their life-likeness, but also their durability. Studies show that more than 95% of implants survive after ten years.
As you may know, single tooth implants are composed of two main parts: a metal post (usually titanium) imbedded in the jawbone; and a life-like crown affixed to the end of the post. But what you may not know is that there are two ways to attach the crown—either with screws or with dental cement.
Neither way is superior to the other—both have their own set of advantages and disadvantages. A cemented crown, for instance, usually looks more like a natural tooth than a screw-retained crown (more about that later) and dentists have more flexibility in making them look natural.
But cemented crowns require an additional piece of hardware called an abutment to better match it with the implant, something unnecessary with a screw-retained crown. Some people can also experience a reaction to the cement resulting in inflammation or even bone loss. And once installed, removing the crown later for repair or replacement is much more difficult than with a screw-retained crown.
Besides attaching directly to the implant, screw-retained crowns don't require cement and are more easily attached and removed. But the screw-hole can pose some aesthetic problems: Although it can be filled with a tooth-colored filling, the tooth's appearance isn't as ideal as a cemented crown.
So, which one is best for you? That will depend on the type and location of teeth being replaced, as well as your dentist's preferences. For instance, a more attractive cemented crown may be better for a visible front tooth, while a screw-retained crown might be a good choice for a back premolar or molar where appearance isn't as big a factor.
In the end, it's likely your dentist will discuss the pros and cons for each method as it pertains to your individual case. Whichever way your crown attaches, the end result will still be a life-like tooth that could last you for years to come.

When you see your dentist about mouth pain, you expect to hear that it's a decayed or fractured tooth, or maybe a gum infection. But you might be surprised if your dentist tells you there's nothing going on inside your mouth to cause the pain.
It's not that far-fetched: The pain could be originating elsewhere. This is known as referred pain, where pain radiates from its origin to another part of the body.
Unless there's an obvious oral cause for the pain, it's best not to undertake any treatment involving the mouth until we've pinpointed the actual cause. That said, the cause is usually not too far away.
Facial nerve disorders. The trigeminal nerve courses on either side of the face from the upper skull through the cheeks and ends around the lower jaw. But if portions of the nerve's protective sheathing become damaged, the slightest touch on the face could trigger prolonged pain. Because of its proximity to the jaw, the pain can often be misidentified as a toothache.
Jaw joint pain. When joints connecting the lower jaw to the skull become traumatized and inflamed, a condition known as Temporomandibular joint disorder (TMD), the pain can radiate toward the jaw. In some cases, the person may easily mistake the muscle pain and spasming for a toothache.
Ear infection. As with TMD, your "toothache" may actually stem from an ear infection or congestion radiating pain into the jaw. It can also happen in the opposite direction—ear pain could actually be the referred pain of an infected back tooth—emphasizing the importance of precisely determining the originating source of any pain in the jaws or face.
Sinus pain. The large maxillary sinuses are located on either side of the face just above the back of the upper jaw. Because of its proximity, pain from a sinus infection can seem to be coming from one of the back molars. And as with ear infections, frequent sinus infections could in fact be caused by an infected tooth penetrating through the sinus floor.
These and other examples of possible referred pain illustrate how "tricky" a presumed toothache can be. Finding the true source of oral or facial pain will ensure you receive the proper treatment for lasting relief.
Buffalo Bills wide receiver Stefon Diggs wrapped up the NFL regular season in January, setting single-season records in both catches and receiving yards. The Bills handily beat the Miami Dolphins, earning themselves the second seed in the AFC playoffs, and Diggs certainly did his part, making 7 catches for 76 yards. But what set the internet ablaze was not Diggs' accomplishments on the field but rather what the camera caught him doing on the sidelines—flossing his teeth!
The Twitterverse erupted with Bills fans poking fun at Diggs. But Diggs is not ashamed of his good oral hygiene habits, and CBS play-by-play announcer Kevin Harlan expressed his support with “Dental hygiene is something to take note of, kids! There's never a bad place to floss” and “When you lead the NFL in catches and yards, you can floss anytime you want.”
We like to think so. There's an old joke among dentists:
Q. Which teeth do you need to floss?
A. Only the ones you want to keep.
Although this sounds humorous, it is borne out in research. Of note, a 2017 study showed that people who floss have a lower risk of tooth loss over periods of 5 years and 10 years, and a 2020 study found that older adults who flossed lost an average of 1 tooth in 5 years, while those who don't lost around 4 teeth in the same time period.
We in the dental profession stress the importance of flossing as a daily habit—and Stefon Diggs would likely agree—yet fewer than 1 in 3 Americans floss every day. The 2016 National Health and Nutrition Examination Survey (NHANES), conducted by the CDC's National Center for Health Statistics, revealed that only 30% of Americans floss every day, while 37% floss less than every day and 32% never floss.
The biggest enemy on the football field may be the opposing team, but the biggest enemy to your oral health is plaque, a sticky film of bacteria and food debris that builds up on tooth surfaces. Plaque can cause tooth decay and gum disease, the number one cause of tooth loss among adults. Flossing is necessary to remove plaque from between teeth and around the gums where a toothbrush can't reach. If not removed, plaque hardens into tartar, which can only be removed by the specialized tools used in the dental office. Regular professional dental cleanings are also needed to get at those hard-to-reach spots you may have missed.
If Diggs can find time to floss during a major NFL game, the rest of us can certainly find a couple minutes a day to do it. While we might not recommend Diggs' technique of flossing from one side of the mouth to the other, we commend his enthusiasm and commitment to keeping his teeth and gums healthy. Along with good dental hygiene at home—or on the sidelines if you are Stefon Diggs—regular professional dental cleanings and checkups play a key role in maintaining a healthy smile for life.
