Although dental implants are best known as single tooth replacements, they can actually play a role in multiple or complete tooth loss (edentulism) restorations. While replacing multiple teeth with individual implants is quite expensive, there’s another way to incorporate them in a restoration at much less cost — as supports for bridges.
In this case, only a few strategically placed implants are needed to support restorations of multiple crowns fused together into a single unit. Implant-based bridges consist of two main types: the first type is a fixed bridge, which is permanently attached to the implants and can’t be removed by the patient. It’s often the preferred treatment for patients who’ve lost most or all of their teeth but have not yet experienced significant bone loss in the jaw.
This choice, however, may not be the best option for patients with significant bone loss. In these cases, there’s a second type of fixed bridge: an implant-supported fixed denture. This type of fixed denture provides support for the lost bone support of the lips and cheeks. If a fixed bridge is not possible due to finances or inadequate bone support to place 4 to 6 implants, a removable denture (also known as an overdenture) that’s supported and held in place by implants is the next best alternative. Unlike a fixed bridge, an overdenture can be removed by the patient for cleaning purposes, and will require less investment than a fixed bridge.
For people with bone loss, the overdenture does more than restore chewing and speech function. Because bone loss can diminish support of the facial structures — actually shorten the distance between the chin and the tip of the nose — an overdenture provides additional bulk to support these structures to improve appearance. Depending on what the patient needs for facial support, overdentures for the upper jaw can be designed as “full palates,” meaning the denture plastic completely covers the upper jaw palate, or open in which the plastic doesn’t completely cover the palate.
Besides the condition of your teeth, gums and bone, your own personal preferences and financial ability will also play a role in which option is best for you. After considering all these factors, we can recommend which of these types of implant-based restorations will fit your needs. With either bridge, fixed or removable, you’ll certainly benefit from the improvement to both your mouth function and your smile.

Your child has had braces for a few months and making good progress with correcting a poor bite (malocclusion), but you’ve also noticed something else: his gums are becoming red and swollen.
These are symptoms of gingivitis, a periodontal (gum) disease. It’s an infection that arises when plaque, a thin film of bacteria and food particles, isn’t adequately removed from teeth with daily brushing and flossing. The braces increase the risk for gingivitis.
This is because the hardware — metal or plastic brackets cemented to the teeth and joined together by metal bands — makes it more difficult to reach many areas of the teeth with a brush or floss string. The plaque left behind can trigger an infection that causes inflammation (swelling) and bleeding.
To exacerbate the situation, gums don’t always take well to braces and can react by overgrowing. Wearing braces may also coincide with a teenager’s surge in hormones that can accelerate the infection. Untreated, gingivitis can develop into advanced stages of disease that may eventually cause tooth loss. The effect is also heightened as we’re orthodontically putting stress on teeth to move them.
You can stay ahead of gingivitis through extra diligence with daily hygiene, especially taking a little more time to adequately get to all tooth surfaces with your brush and floss. It may also help to switch to a motorized brush or one designed to work around braces. You can make flossing easier by using special threaders to get around the wires or a water flosser that removes plaque with a pulsating water stream.
And don’t forget regular dental visits while wearing braces: we can monitor and treat overgrowth, perform thorough dental cleanings and treat occurrences of gingivitis. In some cases you may need to visit a periodontist, a specialist in gums and supporting teeth structures, for more advanced treatment. And if the disease becomes extensive, the braces may need to be removed temporarily to treat the gums and allow them to heal.
Orthodontic treatment is important for not only creating a new smile but also improving your teeth’s function. Keeping a close eye out for gum disease will make sure it doesn’t sidetrack your efforts in gaining straighter teeth.

While they're resilient, your child's teeth aren't invincible. Daily hygiene and regular dental visits are important, but you should also be alert for problems and take action when they arise.
Here are 4 areas that could cause problems for your child's teeth, and what you should do — or not do — if you encounter them.
Teething. This is a normal experience as your child's first teeth erupt through the gums. The gums become tender and painful, causing constant gnawing, drooling, disturbed sleep and similar symptoms. You can help relieve discomfort by letting them bite on a chilled (not frozen) teething ring or a cold, wet washcloth. Pain relievers like ibuprofen in appropriate dosages can also help — but don't apply ice, alcohol or numbing agents containing Benzocaine directly to the gums.
Toothache. Tooth pain could be a sign of decay, so you should see us for an examination. In the meantime you can help relieve pain with a warm-water rinse, a cold compress to the outside of the face, or appropriately-dosed pain relievers. If the pain is intense or persists overnight, see us no later than the next day if possible.
Swollen or bleeding gums. If you notice your child's gums are red and swollen or easily bleed during brushing, they could have periodontal (gum) disease. This is an infection caused by bacterial plaque, a thin film of food particles that build up on the teeth. You can stop plaque buildup by helping them practice effective, daily brushing and flossing. If they're showing symptoms, though, see us for an exam. In the meantime, be sure they continue to gently brush their teeth, even if their gums are irritated.
Chipped, cracked or knocked out tooth. If your child's teeth are injured, you should see us immediately. If part of the tooth has broken off, try to retrieve the broken pieces and bring them with you. If it's a permanent tooth that was knocked out, pick it up by the crown (not the root), rinse it with clean water and attempt to place it back in the socket. If you can't, bring the tooth with you in a container with clean water or milk. The sooner you see us, the better the chances for saving the tooth — minutes count.
If you’re considering a dental implant as a replacement for a lost tooth, you’re looking at a restoration method with an amazing 95% success rate after ten years. But that being said there’s still a risk, albeit quite low, the implant might fail.
And if you smoke, the risk is slightly higher. In a recent study of implant patients, twice as many of the failures occurred in smokers compared to non-smokers. If you’re a smoker, you can increase your chances of a successful outcome if you quit the habit.
Nicotine, a chemical within tobacco, is the primary cause for this higher risk. Besides its effect on the pleasure centers of the brain, nicotine also restricts smaller blood vessels that are abundant in the mouth and skin, causing less blood flow. As a result, the mouth doesn’t have as many antibodies and other substances available to fight infection and help traumatized tissues heal.
Because of this, as well as reduced saliva flow due to the habit, smokers have an increased risk of dental disease and are slower to respond to treatment. This can be especially problematic if the gum tissues around an implant become infected, which could lead to a catastrophic failure. Slower healing also impacts the post-surgery period when bone cells in the jaw are growing and adhering to the implant surface, forming a stronger bond.
To avoid these potential risks you should stop smoking before you undergo implant surgery. If you can’t completely kick the habit, you should at least stop a week before surgery and for two weeks after. It’s also critical that you practice good oral hygiene — both brushing and flossing — to minimize the occurrence of dental disease and see us for regular checkups and maintenance appointments.
Taking these steps will greatly increase your chances of being in the vast majority of people who continue to enjoy success with their implants for many years.
