In the fight against dental disease and other conditions your general dentist is your first line of defense for prevention strategies and treatment. Sometimes, however, your condition may require the services of a dental specialist to restore health to your mouth.
A good example of this is an advanced case of periodontal (gum) disease. While your dentist and hygienist are quite skilled at removing plaque and calculus, there may be extenuating circumstances that may benefit from the knowledge and expertise of a specialist. In the case of gum-related issues that would be a periodontist, a dentist who specializes in the diagnosis and treatment of diseases or disorders related to the gums and bone that support teeth.
There are a number of reasons why you may be referred to a periodontist regarding your gum health. Besides advanced stages of the disease (loose teeth, periodontal pocketing or bone loss) that require surgery or other invasive techniques you may have a particular form that requires advanced treatment, or a secondary condition, like pregnancy or diabetes, which could impact your periodontal condition. There may also be a need for a periodontist’s consultation if you’re preparing for cosmetic restoration, most notably dental implants, that could have a bearing on your gum and bone health.
As your primary oral health “gatekeeper,” your general dentist is largely responsible for determining what you need to achieve optimal health. Likewise, your periodontist or other specialists for other problems will be equally committed to providing you the right care for your situation. Your general dentist and other specialists will work together to ensure that your condition will be cared for, and that you’ll continue to enjoy the highest level of oral health possible.

Periodontal (gum) disease is a bacterial infection, which if left untreated could cause gum recession, bone loss and eventually tooth loss. Caused mainly by plaque left on tooth surfaces from poor hygiene practices, the deeper the infection spreads below the gum line, the more difficult it is to treat.
One possible scenario involves parts of a tooth’s root structure known as furcations. These are branching forks formed during the early development of teeth with multiple roots where they take different paths from the base of the crown. As gum disease spreads around the root it may cause different degrees of bone loss at the point of the branch.
It’s imperative when treating gum disease to uncover and remove any bacterial plaque or calculus (hardened plaque deposits) found, including below the gum line. To address bacterial plaque at the root level, it’s important to first determine if bone loss has involved the furcations (where the roots separate, also referred to as a “furcation invasion”) and to what degree.
We usually classify this degree of involvement in three classes: Class I, the invasion has created a groove in the furcation, but minimal significant bone loss; Class II, the bone loss has extended into the furcation by at least two millimeters; or Class III, the bone loss extends completely from one end of the furcation to the other (or “through and through”).
Depending on the class, cleaning plaque and calculus from furcations and then maintaining them thereafter can be quite challenging. We may need to use specially shaped hand instruments known as scalers or curettes to reach and clean root surfaces, or ultrasonic scalers that use high-frequency vibrations and streaming water to loosen and flush away plaque debris. It may also prove helpful, though limited, to apply antimicrobials or antibiotics to the area to help limit the levels of bacteria.
Disease damage around furcations may also require surgical treatment to encourage new tissue and bone growth in the area. Surgery can also help make the area more accessible to future cleaning and maintenance, both for you and us. Renewed hygiene practices on your part and regular cleaning and checkups with us will help ensure that the situation involving your tooth roots can be kept under control and your tooth preserved for many years to come.
Dental work isn’t performed in a vacuum — the state of your general health can have an impact on procedures and vice-versa. This is especially true if you’re taking certain medications like blood thinners.
Blood thinners such as Warfarin or Clopidogrel are used for a number of medical conditions as an anti-coagulant (inhibiting blood from clotting). They’re commonly part of a stroke or heart attack prevention strategy in patients with cardiovascular disease, or those with tendencies for thrombosis (blood clot formation within blood vessels) or pulmonary embolisms (blood clots within the lungs). They’re also used with patients with artificial heart valves or on a temporary basis with patients who’ve recently undergone knee replacement or similar surgical procedures.
In most cases, dental work won’t be affected by your use of a blood thinner. An issue might arise, however, if an invasive procedure has the potential to cause bleeding, like a tooth extraction or gum surgery. Because the blood doesn’t clot normally it may be difficult to stop the bleeding during such procedures.
To avoid undue complications, it’s always best to let your dentist or oral surgeon know what medications you’re taking, especially blood thinners (this includes low-dose aspirin, a common over-the-counter drug that’s often prescribed as a mild blood thinner). Depending on the procedure and your dosage, they may consult with your prescribing doctor to see if temporarily stopping the medication or reducing the dosage is an acceptable precautionary measure for your dental treatment. Your dentist may also take precautions during the procedure to help reduce bleeding such as using haemostatic agents around the wound site to help stabilize blood clotting, while carefully suturing the wound to avoid disrupting smaller blood vessels (capillaries) that easily bleed.
If your dosage has been temporarily stopped or reduced, you’ll usually be able to resume blood thinners immediately after the dental procedure. Working together, your dentist and doctor will help ensure that your health won’t be at risk and your dental procedure will occur without undue complications.

While there’s usually a period of months between implant placement and the permanent crown, a new technique known as same-day tooth replacement installs both the implant and a temporary crown during the same visit. But be advised — it does have its risks and isn’t for everyone.
Successful same-day replacements require special attention during the three phases for implants: the removal (extraction) of the existing tooth; placement of the implant in the bone; and attachment of the crown, the visible tooth, to the implant. The tooth extraction lays the foundation for the entire process; the extraction procedure must be performed carefully to avoid undue damage to the socket. In addition, if infection or disease has compromised the site, an implant may not be possible immediately.
The implant must then be placed in the bone so that it’s stable and immovable. All implants stabilize with time as the bone grows and adheres to them, but we need greater stability for a same-day tooth replacement when an extraction is performed.
Our last consideration is positioning the implant so that the attached crown blends in naturally with the surrounding gum tissue and adjacent teeth. We must place it at the proper depth below the gum tissues so that the crown appears to emerge from them in the proper tooth length.
Taking extra care during all these phases, including the angle of crown attachment, will increase our chances of success. We still run a risk of implant damage or failure, however, from biting forces before the implant fully integrates with the bone. This means avoiding chewy foods and other situations that might increase the force on the implant. We may also use a temporary crown that’s slightly shorter than adjacent teeth so it won’t make full contact with the opposing tooth.
If you’d like to know if you’re a good candidate for a same-day tooth replacement, see us for a detailed examination. After reviewing your needs, we’ll be able to discuss with you the risks and benefits for a new look in one day.
