Bone and Gum Health


Bon-Gum-Health Bone Health

When you have a missing tooth, the supporting jawbone can suffer from resorption, a breakdown of the jaw bone that worsens with time.  This is because each day your teeth gently touch each other, prompting the bone underneath each tooth to keep rebuilding and maintaining its density. A missing tooth stops this rebuilding of bone.

Resorption weakens the jaw and changes a person’s appearance, giving the face a ‘sunken’ look.  Apart from the aesthetic factors, chronic pain in the jaw joint (TMJ) may result as the gaps make it possible for the remaining teeth to shift position which causes bite relationship problems with the opposing teeth.

If you have missing teeth, you are probably all-too-well aware of problems with chewing your food, particularly raw fruits and vegetables, and the loss of self-confidence associated with this and feel that your general wellbeing suffers.

Dentures are one tooth replacement option but they allow the bone that used to surround your teeth to fade away because a removable denture puts pressure directly on the bone surface resulting in bone wear and inevitably, because of this, the denture starts to lose its fit and can slip and slide when you speak or eat. 

Implants are a better long term option for most people, but prompt action to replace the missing tooth is important as the gradual loss of jawbone which is required to support the implants can lead to more expensive treatment as bone grafting surgery may be required to stabilise the implant.

 

Available Treatments

Bone Grafting & Sinus Augmentation

If you have insufficient bone to have an implant placed, then a bone grafting procedure can be performed.

This procedure replaces missing bone with a material called a bone graft which also assists your body re-grow lost bone or mend jaw bone defects that can occur due to the effects of long-term missing teeth or infection.

The new bone growth subsequently fortifies the grafted area by developing a bridge between the existing bone and the graft. The newly formed bone then replaces most of the grafted material.

At CARE Dentistry, we also provide a procedure known as Guided Bone Regeneration which uses a membrane over the graft site that further encourages new bone to growth. It also thwarts the development of scar tissue in the grafted area.

We can also perform sinus augmentation which is where bone is added to the upper jaw area around the premolar and molar teeth. The ultimate aim of this delicate procedure is to have enough bone in the targeted location to then support a dental implant which can also be done at our centre.

 

 


Gum Health Gum Health

Periodontal (gum) diseases such as gingivitis and periodontitis are infections that must be treated as they can result in tooth loss if ignored.  They arise when the bacteria in plaque causes the gums to become irritated. Gingivitis is the lesser of the two and, while causing little discomfort, can be identified when your gums become red, swollen and bleed easily.  Left untreated, gingivitis can develop into periodontitis where plaque spreads and grows underneath the gum line and the toxins produced by the bacteria irritate the gums.  Gums become detached from the teeth and form infected pockets which develop as the disease progresses, destroying gum tissue and bone which, in turn, causes teeth to become loose and require extraction.

Inadequate oral hygiene is often the cause of gingivitis but it is reversible with proper dental treatment and good oral attention at home.  Non-surgical treatment includes scaling and root planing (cleaning of the root surfaces), antimicrobials and host modulation.  If the tissue around your teeth is not responding effectively to non-surgical treatment, you will need periodontal surgery to correct this.

Available Treatments

Periodontal Procedures

In the first phase of your treatment, special instruments will be used to carefully and thoroughly clean (debride) and polish each tooth and its root surfaces. The aim is to clean deep below the gum line and remove all deposits, right to the base of the gum pocket. This is usually completed over several appointments using local anaesthetic to minimize discomfort.

After a healing period of several weeks, you will be required to return for a review appointment to assess your response to the initial treatment. There can be great variation between individual ‘s reactions to periodontal treatment, due to the different inflammatory responses to plaque and calculus within the population. Occasionally (less than 10% of the time), the areas of inflammation do not respond to scaling and root planing. In these instances, gum access surgery may be required to allow deeper access and visual observation of the root surface, and facilitate the removal of plaque and calculus.

Given your susceptibility to gum disease, you will always be at risk of further periodontal destruction. As such you will require gum assessments for the rest of your life. Any treatment we undertake will not change your body's inflammatory reaction to the presence of plaque, and thus we can never fully ‘cure’ your gum disease. However, if all the plaque or calculus is removed, there can be no inflammatory response, thus it is possible to maintain the health of your teeth and gums for the long term.

Regular reassessment visits are essential for people with periodontal disease. With continual monitoring, we can prevent the recurrence of periodontal disease in areas where plaque is inadvertently left on the teeth. Eventually a regular interval will be established which is best optimised for you to maintain your gums free of plaque and bleeding. This will be shared between your general dentist and our periodontal clinic.
