YourQuestforaDentalImplantMightBeInterruptedbyBoneLoss

Years ago, disease or trauma robbed you of one of your teeth. At the time you might have opted for an affordable solution, like a partial denture. But now you'd like to restore that missing tooth with a dental implant, the most life-like tooth replacement available.

That's a great decision. But there may be a hiccup along the way to your new implant: the state of the underlying jawbone. Implants need a certain amount of bone for proper placement. If not enough is present, that may cause an interruption in your plans—and that could be a real possibility if your tooth has been missing for some time.

That's because, like other living tissues, bone has a growth cycle: Old bone cells die and dissolve, while new cells form to take their place. In the jaw, the force produced by teeth during chewing helps to keep this growth process in the bone functioning at a healthy pace.

When a tooth goes missing, though, so does this chewing stimulation. A lack of stimulation can slow the growth rate for that part of the bone and its volume can diminish over time. It's possible for a quarter of the bone volume to be lost within the first year after losing a tooth.

If you've experienced that level of bone loss, we may not be able to place an implant—yet. You might still have a few options. For one, we could attempt to regenerate some of the bone through grafting. Bone material grafted into the affected area can serve as a scaffold for new bone cells to form and adhere. Over time, this could result in a sufficient amount of regenerated bone to support a dental implant.

Another possibility might be to install a smaller diameter implant like those used to support removable dentures. Because they're smaller they require less bone than standard-sized implants. They're not for every situation, though, and are best suited for situations where aesthetics isn't a priority.

To know what your options are regarding an implant-based restoration, you'll need to undergo a thorough evaluation of your oral health, including supporting bone. Depending on your situation, you may still be able to renew your smile with this premier tooth replacement option.

ToothinOneDayProceduresRequireSpecialAttentionforSuccess

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.

ImprovingHygieneSkillsMaximizesRemovalofDisease-CausingPlaque

Your mouth is teeming with bacteria—millions of them. But don't be alarmed: Most are benign or even beneficial. There are, however, some bacteria that cause tooth decay or periodontal (gum) disease, which can damage your oral health.

These disease-causing bacteria feed and multiply within a thin biofilm of leftover food particles on tooth surfaces called dental plaque. To reduce these bacterial populations—and thus your disease risk—you'll need to keep plaque from building up through daily brushing and flossing.

Now, there's brushing and flossing—and then there's effective brushing and flossing. While both tasks are fairly simple to perform, there are some things you can do to maximize plaque removal.

Regarding the first task, you should brush once or twice a day unless your dentist advises otherwise. And "Easy does it" is the rule: Hard, aggressive scrubbing can damage your gums. A gentle, circular motion using a good quality toothbrush will get the job done. Just be sure to brush all tooth surfaces, including the nooks and crannies along the biting surfaces. On average, a complete brushing session should take about two minutes.

You should also floss at least once a day. To begin with, take about 18" of thread and wrap each end around an index or middle finger. Pulling taut and using your thumbs to help maneuver the thread, ease the floss between teeth. You then wrap it around each tooth side to form a "C" shape and gently slide the floss up and down. Continue on around until you've flossed between each tooth on both jaws.

You can get a rough idea how well you did after each hygiene session by rubbing your tongue against your teeth—they should feel slick and smooth. If you feel any grittiness, some plaque still remains. Your dentist can give you a more precise evaluation of your cleaning effectiveness at your regular dental visits. This is also when they'll clean your teeth of any missed plaque and tartar.

While professional dental cleanings are important, what you do every day to remove plaque is the real game changer for optimum oral health. Becoming a brushing and flossing "ninja" is the best way to keep your healthy smile.
