When people lose a tooth, the conversation usually turns quickly to the replacement. Will it look natural? How long will it last? What will it cost? Those are fair questions, but there is an earlier one that shapes all the others: are the gums and bone around that space healthy enough to hold an implant over the long term?
An implant is anchored in bone and surrounded by gum tissue, just like a natural tooth. If that tissue is inflamed or infected, the new implant sits in the same conditions that may have cost the patient a tooth in the first place. This article explains, in general terms, why gum disease is usually treated before implant surgery and what that means for patients and for students learning about dental care.
Gum disease starts when plaque, a sticky film of bacteria, builds up along the gumline. In its early stage, called gingivitis, the gums may look red, feel tender or bleed when brushed. At this point, the damage is usually reversible with better cleaning at home and professional care.
If it is not treated, gingivitis can progress to periodontitis. The gums start to pull away from the teeth, forming pockets where bacteria collect. Over time, the bone and fibers that hold teeth in place break down, and teeth can loosen or be lost.
Common warning signs include:
Gums that bleed during brushing or flossing
Persistent bad breath or a bad taste
Gums that look swollen or have pulled back from the teeth
Teeth that feel loose or have shifted
Changes in how your bite feels
Periodontitis is common in adults, and it often develops without pain, which is why many people do not know they have it. The Centers for Disease Control and Prevention offers public health information on oral health, including gum disease and the risk factors linked to it, such as smoking and diabetes.
The details vary from person to person, but treatment before implants often follows a broad sequence:
Examination and measurement. The clinician checks pocket depths around each tooth, looks for bleeding and takes X-rays to see bone levels.
Deep cleaning. Scaling and root planing removes hardened deposits from above and below the gumline and smooths the root surfaces.
Re-evaluation. After a healing period, the gums are checked again to see how they responded.
Further treatment if needed. Some deeper pockets may need additional care, which can include surgical options.
Implant planning. Once the gums are stable, the team plans implant placement and any bone grafting.
Some patients see a periodontist, a dentist with specialist training in gums and the bone that supports teeth. In Burnaby, BC, for example, IMPress Perio Implant Center is a periodontal and implant practice that offers both non-surgical gum treatment, such as scaling and root planing, and implant placement, which allows the same team to follow the gums from treatment through to the implant. Patients elsewhere can ask their general dentist whether a referral makes sense.
It is easy to think of an implant as a fresh start. In one sense it is, because titanium and porcelain do not decay. But the bacteria that cause gum disease do not need a natural tooth to cause harm. They can collect around an implant too.
If active gum disease is left untreated elsewhere in the mouth, those bacteria remain present when the implant is placed. The tissues around the new implant have to heal and form a seal while surrounded by ongoing infection. That is a weaker starting point than a mouth where the disease has been brought under control.
There is also the bone to think about. Periodontitis can wear away the bone an implant needs for support. A clinician will want to know how much healthy bone remains and whether grafting may be needed, and that assessment is more reliable once inflammation has settled.
Inflammation around implants comes in two main stages. The first, peri-implant mucositis, affects only the soft tissue. It can cause redness and bleeding around the implant and is generally considered reversible with treatment and better cleaning.
The second, peri-implantitis, goes further. The inflammation spreads to the bone around the implant, and that bone is gradually lost. In advanced cases, the implant can loosen or fail.
Research has linked a history of periodontitis with a higher risk of peri-implantitis. Poor plaque control, smoking and missed maintenance visits are also considered risk factors. This is a big reason why clinicians tend to treat gum disease first and keep monitoring it afterward. It does not mean a person with past gum disease cannot have implants. Many do. It means the gums need to be stable before surgery, and the patient needs a plan to keep them that way.
Clinical treatment works best when it is backed up at home. Steps that generally help include:
Brushing twice a day with a soft brush, angled toward the gumline
Cleaning between teeth and around implants daily, using floss, interdental brushes or a water flosser as advised
Stopping smoking or vaping, ideally well before surgery
Keeping conditions such as diabetes well managed with your physician
Keeping every maintenance appointment, even when nothing hurts
Implant patients are often placed on a regular maintenance schedule, sometimes more often than every six months, especially if they have had gum disease before.
Healthy gums give an implant the best possible setting to heal and last. Every patient's mouth is different, so use this as background reading only, and follow the advice of your own dentist or periodontist about the timing and type of treatment that suits you.
