If you’re in the initial planning stages for a dental implant, you may already be encountering a number of options to consider. One that may come up is how the visible crown will attach to the metal implant imbedded in the bone.
Generally speaking, implants are composed of two parts: a metal post most often made of titanium placed into the bone that serves as the “root” for the new tooth; and a visible, life-like crown made of dental porcelain that attaches to an abutment on the titanium post. The crown can be attached in one of two ways: either with a small screw through the biting surface of the crown into a receiving hole in the abutment or cemented to it.
The major advantage of a screwed crown is that it allows for easy removal of the crown if needed. While the titanium post can often last a lifetime, porcelain crowns more often need repair or replacement since they receive the brunt of the biting forces in the mouth. A screw-attached crown is much easier to remove than a cemented one.
On the other hand, screwed crowns have a small access hole that must be restored with a tooth-colored filling to help the crown appear natural. This isn’t too great an issue with back teeth but does make achieving a natural appearance in the front more difficult. Cemented crowns look more like a natural tooth and are thus more flexible in achieving the desired appearance.
Besides the possibility the cement may cause gum inflammation or bone loss, the chief detraction from cemented crowns is the difficulty in removing them. Crowns are often damaged in this process so it’s highly likely it will have to be replaced rather than repaired. It’s possible to use weaker cement, but this raises the risk of the crown coming loose at some point from the abutment.
As we plan for your implant, we’ll discuss which type of attachment will work best for you, depending on the tooth to be replaced and other conditions with your oral health. The end result, though, should be the same — a new, natural-looking tooth that serves you well for many years to come.

Your teeth and gums are filled with nerves that make the mouth one of the most sensitive areas in the body. But thanks to local anesthesia, you won't feel a thing during your next dental procedure.
The word anesthesia means “without feeling or pain.” General anesthesia accomplishes this with drugs that place the patient in an unconscious state. It's reserved for major surgery where the patient will be closely monitored for vital signs while in that state.
The other alternative is local anesthesia, which numbs the area that needs treatment, while allowing the patient to remain conscious. The anesthetics used in this way are applied either topically (with a swab, adhesive patch or spray) or injected with a needle.
In dentistry, we use both applications. Topical anesthesia is occasionally used for sensitive patients before superficial teeth cleaning, but most often as an “opening act” to injected anesthesia: the topical application numbs the gums so you can't feel the prick of the needle used for the injectable anesthetic. By using both types, you won't feel any pain at all during your visit.
Because of possible side effects, we're careful about what procedures will involve the use of local anesthesia. Placing a sealant on the exterior of a tooth or reshaping enamel doesn't require it because we're not making contact with the more sensitive dentin layer beneath. We've also seen advances in anesthetic drugs in which we can now better control the length of time numbness will persist after the procedure.
All in all, though, local anesthesia will make your dental care more comfortable — both for you and for us. Knowing you're relaxed and comfortable allows us to work with ease so we can be unhurried and thorough. By keeping pain out of the equation, your dental care has a better chance for a successful outcome.

Mayim Bialik has spent a good part of her life in front of TV cameras: first as the child star of the hit comedy series Blossom, and more recently as Sheldon Cooper’s love interest — a nerdy neuroscientist — on The Big Bang Theory. (In between, she actually earned a PhD in neuroscience from UCLA…but that’s another story.) As a child, Bialik had a serious overbite — but with all her time on camera, braces were just not an option.
“I never had braces,” she recently told Dear Doctor – Dentistry & Oral Health magazine. “I was on TV at the time, and there weren’t a lot of creative solutions for kids who were on TV.” Instead, her orthodontist managed to straighten her teeth using retainers and headgear worn only at night.
Today, there are several virtually invisible options available to fix orthodontic issues — and you don’t have to be a child star to take advantage of them. In fact, both children and adults can benefit from these unobtrusive appliances.
Tooth colored braces are just like traditional metal braces, with one big difference: The brackets attached to teeth are made from a ceramic material that blends in with the natural color of teeth. All that’s visible is the thin archwire that runs horizontally across the teeth — and from a distance it’s hard to notice. Celebs like Tom Cruise and Faith Hill opted for this type of appliance.
Clear aligners are custom-made plastic trays that fit over the teeth. Each one, worn for about two weeks, moves the teeth just a bit; after several months, you’ll see a big change for the better in your smile. Best of all, clear aligners are virtually impossible to notice while you’re wearing them — which you’ll need to do for 22 hours each day. But you can remove them to eat, or for special occasions. Zac Efron and Katherine Heigl, among others, chose to wear clear aligners.
Lingual braces really are invisible. That’s because they go behind your teeth (on the tongue side), where they can’t be seen; otherwise they are similar to traditional metal braces. Lingual braces are placed on teeth differently, and wearing them often takes some getting used to at first. But those trade-offs are worth it for plenty of people. Which celebs wore lingual braces? Rumor has it that the list includes some top models, a well-known pop singer, and at least one British royal.
So what’s the best way to straighten your teeth and keep the orthodontic appliances unnoticeable? Just ask us! We’d be happy to help you choose the option that’s just right for you. You’ll get an individualized evaluation, a solution that fits your lifestyle — and a great-looking smile!

Wearing braces isn't just for teenagers — straightening teeth can be just as viable a need when you're an adult. For example, it may be necessary to first move teeth away from an empty tooth socket before you obtain a dental implant or other restoration.
But braces could have complications, especially if you have periodontal (gum) disease. These infections caused by plaque, a thin film of bacteria and food particles, inflame and weaken gum tissues and erode supporting bone. It can be treated and brought under control — but keeping it under control requires daily brushing and flossing, along with frequent office cleanings and checkups.
Braces can make this more difficult: it's harder to brush and floss effectively through the hardware of brackets and wires, which can give plaque a chance to build up. Patients susceptible to gum disease are more likely to have re-infections while wearing braces. The hardware can also cause enamel to come in prolonged contact with acid, which can dissolve its mineral content and open the door to tooth decay.
Clear aligners are an alternative to braces that can accomplish tooth movement while minimizing infection flare-ups for people with gum disease. Aligners are a series of customized clear plastic trays worn over the teeth, with each succeeding tray incrementally moving the teeth further than the preceding one. After wearing one tray for a specified time period, you then switch to the next tray. The teeth gradually move to the desired new position over the course of the aligner series.
This option is especially advantageous for gum disease patients because the trays can be removed temporarily for brushing and flossing. There are also other benefits: we can hide a missing tooth space with a temporary false tooth attached to the aligner; and, they're nearly invisible so it won't be obvious to others you're undergoing orthodontic treatment.
Not all orthodontic situations benefit from this alternative, while some cases may call for a combination approach between aligners and braces. But in the right setting, clear aligners are a good choice for not only obtaining better teeth position, but also helping you avoid a new encounter with dental disease.
So, you’ve just acquired an attractive restoration with dental implants. You may be thinking at least with these teeth you won’t have to worry about dental disease.
Think again. While the implants and their porcelain crowns are impervious to decay the surrounding gums and bone are still vulnerable to infection. In fact, you could be at risk for a specific type of periodontal (gum) disease called peri-implantitis (inflammation around the implant).
Bacterial plaque, the thin bio-film most responsible for gum disease, can build up on implant crowns just as it does on natural tooth surfaces. If it isn’t removed with daily brushing and flossing and regular dental cleanings the bacteria can trigger an infection in the gums.
Besides weakening gum tissues, gum disease can also cause bone loss, of critical importance to dental implants. An implant depends on the bone they’re inserted in to hold them in place. If the bone around an implant becomes infected it could begin to be lost or dissolve (resorb), which could lead to loss of the implant.
That’s why it’s critical to keep the natural tissue structures supporting your implants infection-free. Not only is daily hygiene a must, but your implants and any remaining natural teeth should undergo professional cleaning at least twice a year or more if your dentist recommends it.
Cleanings involving implants will also be a bit different from natural teeth. While the dental materials used in the crown and implant post are quite durable, regular cleaning instruments can scratch them. Although tiny, these scratches can become hiding places for bacteria and increase your risk of infection.
To avoid this, your hygienist will use instruments (known as scalers and curettes) usually made of plastics or resins rather than metal. The hygienist may still use metal instruments on your remaining natural teeth because their enamel can tolerate metal without becoming scratched creating a smoother surface.
While keeping implants clean can sometimes be a challenge, it’s not impossible. Implants on average have a long-term success rate above 95%. With both you and your dentist caring and maintaining these state-of-the-art restorations, you may be able to enjoy them for decades.
