Dental implants are today’s closest restorative facsimile to natural teeth. And they’re versatile: not only can they replace single teeth but they can also support bridges or dentures.
But since one of their crucial components is made of metal, are you out of luck obtaining this state-of-the-art dental restoration if you have a metal allergy?
The answer is: probably not—it’s rare for implants to cause an allergic reaction. Still, metal allergies can be a potential problem within your mouth as with other areas of health.
An allergy originates from the body’s necessary response to potentially harmful microorganisms or substances. Sometimes, however, this response becomes chronic and exaggerated, creating an allergy. People can have allergies to nearly anything with responses ranging from a minor rash to a potentially life-threatening multi-organ system shutdown (anaphylactic shock).
A small number of people have allergies to particular metals. One of the most common is nickel, which affects an estimated 17% of women and 3% of men; cobalt and chromium are also known to cause allergies. Consumer exposure, particularly metal contact with the skin through jewelry or clothing, is the most prevalent, but not the most concerning. That’s reserved for metal allergies related to medical devices like coronary stents or hip and knee prostheses. And in dentistry, there are rare occasions of inflammation or rashes from metal amalgam fillings.
Which brings us to dental implants: the main metal post that’s inserted into the jawbone is usually made of titanium. It’s the metal of choice for two reasons: it’s bio-compatible, meaning the body normally accepts its presence; and it’s osteophilic, which means bone cells readily grow and adhere to it, a major reason for implant durability.
While it’s possible for someone to have an allergy and subsequent reaction to implants with titanium, the occurrences appear to be extremely low. In one study of 1,500 patients, titanium allergies were estimated to be a factor in implant failures in less than 1% of those studied.
Even so, if you have known metal allergies you should make sure your dentist knows. Being aware of all the facts will help them recommend the best tooth replacement choice for you—and hopefully it will be dental implants.

Due to financial circumstances, people often have a lost tooth restored with a removable partial denture, an effective appliance that restores function and a degree of aesthetic appearance. Later, though, they may want to improve both function and appearance with a dental implant.
If this describes you, you’re making a great choice. Dental implants are the closest technology we have to a natural tooth. But there may be a roadblock to your implant, especially if a long time has passed since your tooth loss—there may not be enough bone at the site to place an implant.
The heart of an implant is a titanium metal post surgically imbedded in the jawbone. The titanium naturally attracts bone cells, which grow and adhere to it to form a solid hold that can support a porcelain crown or other restorations like bridges or dentures. But to achieve a natural appearance it’s important that the implant is placed in the right location. To achieve that requires adequate bone.
But there may not be adequate bone if the tooth has been missing for a while. The forces generated when we chew travel through the teeth to the jawbone, which stimulates bone growth. If that stimulus is absent because of a missing tooth, new bone cells may not replace older ones at a healthy rate and the total bone volume begins to diminish. A denture can’t compensate and, in fact, accelerates bone loss.
But there may be a solution: bone grafting. With this procedure we place a donor bone graft into the area of bone deficiency some time before implant surgery. The graft serves as a scaffold for new bone cells to grow upon. Hopefully, this will produce enough healthy bone to support an implant. If the bone deficiency is minor, we may place the implant and the bone graft at the same time.
If you have experienced bone loss, we must first determine the amount of bone at the missing tooth site and whether grafting is a viable option. Bone grafting postpones your implant, but the delay will be worth the wait if we’re successful. With increased bone volume you’ll be able to obtain a new tooth that’s superior to your current restoration.
For most people, going to the dentist is as routine as getting their oil changed. But if you're like the one in ten people with severe anxiety, dental visits are anything but routine.
What may have begun as a childhood fear has turned for many people into a lifetime avoidance of dental care. Â This absence of dental cleanings, checkups and treatments can have an adverse effect on not only their oral health but their general health too.
But there are ways you can reduce dental visit anxiety, beginning first with finding a compassionate dental provider. A good dentist-patient relationship is important for everyone, but more so for people with anxiety. Building a trust relationship with a dentist who listens and accepts your fears without judging is your first step to overcoming them.
Though finding an understanding provider is important, it may not be enough in the beginning of your return to regular dental care. To help you further relax during visits, we can also provide medicinal therapies known collectively as sedation.
Although it has some similarities, sedation is different from anesthesia. The latter deadens pain sensation; sedation aims to calm your emotions. The most common sedation is taken in oral form, usually a pill (or syrup for children) taken an hour or so before the appointment. Oral sedation is often used in conjunction with gases like nitrous oxide and local anesthesia.
For a more relaxed state (especially during an involved procedure) we may use intravenous (IV) sedation. With this method we deliver the medication through a small needle or catheter inserted into a vein.
IV sedation places you in a reduced state of consciousness. But it isn't a “sleep” state as what's achieved during general anesthesia, but more of a “semi-awake” state. You won't need assistance with breathing or heart function and you can respond to verbal or touch commands. Many drugs used for IV sedation also have an amnesiac affect, so you won't remember many details about the procedure.
Depending on your level of anxiety, we can match the right therapy to induce calm and relaxation. Sedation can help you see dental visits in a more positive light so that it truly does become a life routine.

It's no secret that many of Hollywood's brightest stars didn't start out with perfectly aligned, pearly-white teeth. And these days, plenty of celebs are willing to share their stories, showing how dentists help those megawatt smiles shine. In a recent interview with W magazine, Emma Stone, the stunning 28-year-old star of critically-acclaimed films like La La Land and Birdman, explained how orthodontic appliances helped her overcome problems caused by a harmful habit: persistent thumb sucking in childhood.
“I sucked my thumb until I was 11 years old,” she admitted, mischievously adding “It's still so soothing to do it.” Although it may have been comforting, the habit spelled trouble for her bite. “The roof of my mouth is so high-pitched that I had this huge overbite,” she said. “I got this gate when I was in second grade… I had braces, and then they put a gate.”
While her technical terminology isn't quite accurate, Stone is referring to a type of appliance worn in the mouth which dentists call a “tongue crib” or “thumb/finger appliance.” The purpose of these devices is to stop children from engaging in “parafunctional habits” — that is, behaviors like thumb sucking or tongue thrusting, which are unrelated to the normal function of the mouth and can cause serious bite problems. (Other parafunctional habits include nail biting, pencil chewing and teeth grinding.)
When kids develop the habit of regularly pushing the tongue against the front teeth (tongue thrusting) or sucking on an object placed inside the mouth (thumb sucking), the behavior can cause the front teeth to be pushed out of alignment. When the top teeth move forward, the condition is commonly referred to as an overbite. In some cases a more serious situation called an “open bite” may develop, which can be difficult to correct. Here, the top and bottom front teeth do not meet or overlap when the mouth is closed; instead, a vertical gap is left in between.
Orthodontic appliances are often recommended to stop harmful oral habits from causing further misalignment. Most appliances are designed with a block (or gate) that prevents the tongue or finger from pushing on the teeth; this is what the actress mentioned. Normally, when the appliance is worn for a period of months it can be expected to modify the child's behavior. Once the habit has been broken, other appliances like traditional braces or clear aligners can be used to bring the teeth into better alignment.
But in Stone's case, things didn't go so smoothly. “I'd take the gate down and suck my thumb underneath the mouth appliance,” she admitted, “because I was totally ignoring the rule to not suck your thumb while you're trying to straighten out your teeth.” That rule-breaking ended up costing the aspiring star lots of time: she spent a total of 7 years wearing braces.
Fortunately, things worked out for the best for Emma Stone: She now has a brilliant smile and a stellar career — plus a shiny new Golden Globe award!

You've seen the ads for obtaining a new tooth in one day with a dental implant. Those aren't exaggerated claims — you can leave the dental office the same day with a new tooth that looks and functions like the old one.
But the dramatic marketing aside, there is a bit more to the story. Same day tooth replacement isn't appropriate in every situation. And even when it is, there are risks for failure.
We can minimize those risks, however, by focusing on certain goals during the three distinct phases in the process: removing the natural tooth; placing the metal implant into the jawbone; and affixing the visible, crown.
It's crucial during tooth extraction that we avoid damaging the socket bone that will ultimately support the implant's titanium post. If the socket walls break down it could set up future gum recession or cause us to abort the implant procedure altogether that day.
When placing the implant, we want to focus on achieving a strong hold. Due to its special affinity with titanium, bone cells gradually grow and adhere to the post to firmly anchor the implant in time. But since we're immediately loading a crown rather than allowing the bone to fully integrate first, we need to ensure the implant has a secure hold from the get-go. We can only achieve this with precise placement based on careful examination and planning, as well as adequate bone.
Even so, the implant still needs to integrate with the bone for a lasting hold, and that takes time. Even with normal biting forces the implant risks damage during this integration period. That's why we place a temporary crown a little shorter than the surrounding teeth. Those adjacent teeth will take the brunt of the biting force and not the implant.
Once the bone has fully integrated, we'll replace the temporary crown with a permanent one the proper height proportional to the other teeth. Even with the temporary crown, though, you'll still have a life-like tooth the day we removed the older one.
The key to success is planning — first determining if you meet the criteria for a same-day implant and then mapping out and carefully executing each succeeding step. Doing this will ensure your same-day implant is a success from day one.
