Allergic reactions aren't necessarily bad: they're your body's responses to possible threats from foreign substances. But the response can go too far and cause a reaction as minor as a skin rash or as life-threatening as a multi-system shutdown called anaphylaxis.
Anything can cause an allergy: animal fur, food, chemicals — or metals. Because metals play such a large role in dental care, it's only natural we're alert to the possibility of allergic reactions from a procedure.
But don't postpone your implants or other dental work just yet — the threat isn't nearly that ominous. Here are a few facts about dental metal allergies to help you sort it out.
Allergic reactions are rare for metals used in medical and dental procedures. Although reactions to metals in joint replacements or coronary stents leading to failure do happen, actual occurrences are rare. Most metal allergies manifest as a skin reaction to jewelry or clothing. It's less likely with medical or dental metals because they're chosen specifically for their compatibility with living tissue.
Amalgam fillings account for most dental work reactions. Dentists have used this multi-metal alloy for fillings and other restorations for well over a century. Tooth-colored resins are now used for most fillings, but amalgam is still used in less visible back teeth. It's very rare for a person to experience a reaction to amalgam, but when it does occur it usually results in minor inflammation or a rash.
Implant titanium isn't just bio-compatible — it's also osteophilic. Titanium is the perfect choice for implants not only because it's tissue friendly, but also because it's bone friendly (osteophilic). Once implanted in the jaw, bone cells naturally grow and adhere to it to create a more durable bond. Not only does the body usually tolerate titanium, it welcomes it with open arms!
While it's still possible for you to have an allergy to implant titanium, the chances are remote. In one recent study involving 1,500 implant patients, titanium allergies occurred in less than 1%. So the chances are high a metal allergy won't stop you from obtaining a smile-transforming restoration with dental implants.

You've seen ads for “Teeth in One Day” that promise immediate implant placement at the same time you have the problem tooth removed. But this presumes the gums and underlying bone are healthy and able to support and protect the implant. If that's not the case, it may be ill-advised to place an implant on the same day.
Even with immediate placement, there will be a small degree of bone and gum opening or space around the implant after it's placed into the socket. This can often be remedied by placing a bone graft and sometimes a gum graft when we install the implant. It's also possible for natural healing to gradually fill in the space, but we'll need to monitor the site carefully for several weeks.
On the other hand, if we detect significant bone loss (or strongly suspect it will occur), immediate placement may not be an option — there's not enough bone or it's too weak to support an implant. In this case, it's necessary to wait on placement and focus on improving the bone health and quantity, beginning when we remove the old tooth and place a bone graft.
After completing the extraction, we typically place a bone graft in the empty socket. The graft will become a “scaffold” for new bone cells to grow upon. We may then allow about two to four months for new bone to partially replenish the area and then place the implant. The bone will continue to regenerate as it grows and attaches to the titanium implant to create a solid attachment.
If the site, however, still appears fragile even after partial bone growth, we may opt to wait another two to four months before attempting placement. From a long-term perspective, this is the best scenario for ensuring a durable foundation for the implant. It also allows for a socket severely compromised by disease to heal more thoroughly.
To determine which of these placement scenarios is best for you, we'll first need to conduct a thorough dental examination. From there we'll be in a better position to discuss the right implant timeline for your situation. Our main goal is to ensure we can securely place your implant in just the right position to achieve the most successful and attractive result.

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.

Since boxers first began using them a century ago, athletic mouthguards are now standard safety equipment for most contact sports. Without them, dental injuries would skyrocket.
But a recent study in the peer-reviewed journal, General Dentistry, indicates there’s another important reason to wear a mouthguard for contact sports or exercise: you may be able to significantly reduce your risk for a mild traumatic brain injury (MTBI), better known as a concussion. It’s believed the mouthguard absorbs some of the force generated during contact, resulting in less pressure to the brain. That reduction is even more significant if your mouth-guard has been custom-made by a dentist.
That last finding is important, because not all mouthguards on the market are equal. There are three basic categories of mouthguards — stock, “boil and bite,” and custom. Stock mouthguards come in limited sizes; they’re relatively inexpensive, but they provide the least level of protection. “Boil and bite” can be customized after purchase to the wearer’s bite, but they don’t always provide complete coverage of back teeth. Custom mouthguards are designed and fashioned by a dentist; they’re relatively expensive (running in the hundreds of dollars), but there’s ample evidence they provide the highest level of protection from mouth injuries.
The General Dentistry study also corroborates custom mouthguards’ effectiveness in preventing concussions. The study followed approximately 400 football players from six different high school teams. While all the players wore the same type of helmet, half of them wore custom-made mouthguards and the other half wore stock guards. 8.3% of the athletes wearing stock guards experienced a concussion injury; by contrast only 3.6% of those with custom guards sustained an injury — greater than half fewer occurrences.
The study also highlights the need not to rely solely on helmets or other protective headgear for concussion prevention. It’s important to include mouthguards along with other athletic protective gear to lower injury risk as much as possible.
So when considering how you can provide the optimum injury protection for you or your child, be sure to include an athletic mouthguard, preferably one that’s custom-made. We’ll be happy to advise you further on what you need to know to prevent traumatic dental injuries, as well as concussions.

Even after losing a tooth in an on-court collision with an opposing player, Isaiah Thomas didn’t slow down. The Boston Celtics point guard completed the play…and the rest of the game. Unfortunately, that wasn’t the end of his dental problems — it was just the beginning.
Over the next few days, Thomas had a total of ten hours of oral surgery to treat problems with multiple teeth. He got a temporary bridge, and will receive a permanent one at a later date. He also got fitted for a custom-made mouthguard to prevent re-injury.
We’re pleased to see that Thomas is getting appropriate dental treatment. But it’s unfortunate that he didn’t get the mouthguard sooner; this one piece of inexpensive safety gear could have saved him a lot of pain and trouble. If you think mouthguards are strictly for full-contact sports, Thomas’ troubles should make you think again. In fact, according to a 2015 study in the journal Sports Health, the five sports with the highest overall risk of tooth loss are basketball, football, hockey, martial arts, and boxing. Plenty of other also involve the risk of dental injury.
The study also notes that some 5 million teeth are avulsed (knocked out) each year in the U.S. alone. Countless others are loosened, fractured or chipped. What’s more, it is estimated that the lifetime cost of treating an avulsed tooth is between $5,000 and $20,000. The cost of a custom-made mouthguard is just a small fraction of that.
Where can you or your child get a custom-made mouthguard? Right here at the dental office! These high-quality items are professionally fabricated from a model of your actual teeth, so they fit much better than an off-the-shelf one ever could. They offer superior protection, durability and comfort — because, after all, no mouthguard can protect you if it’s too uncomfortable to wear.
Thomas’ season is now over due to a hip injury, but at least he will now have time to rest and get his dental problems taken care of. Let’s hope his story will inspire more athletes — both professional and amateur — to prevent similar problems by wearing custom-made mouthguards. Whether you compete on a school team, enjoy a pick-up game after work, or play in the big leagues, a dental injury is one problem that you don’t need.
