The Clinic

MARCHWOOD DENTAL Clinic

In 2005, Dr. Bahram Mostaghaci and Dr. Bill Henry met while instructing students at Algonquin College’s advanced restorative hygiene program. Their instant chemistry and philosophy for providing patient-centric dentistry soon led to a professional partnership.

 

Together as partners they established Marchwood Dental on a beautiful property at the corner of Halton Terrace and March Road. The existing Richardson homestead on the property was completely redesigned in 2006, becoming what is now our showcase dental practice.

 

After a ten-year partnership, Dr. Mostaghaci became sole owner in 2016. Dr. Henry continued to work until his eventual retirement in 2025. We are lucky to have a highly caring and talented team of associate dentists who continue to implement our original vision and office philosophy. As always, we remain committed to being on the cutting edge of innovative dental technology, within the heart of Kanata North’s renowned hi-tech hub, while treating all our patients like family.

DENTAL IMPLANTS

Dental Implants

Dental implants are used to replace missing teeth by supporting a natural-looking restoration. The implant itself is a small titanium post that is placed where the tooth root would normally be, creating a stable foundation for a crown, bridge, or denture.

 

Over time, the surrounding bone and gum tissue can heal around the implant, helping hold it securely in place. Because the implant replaces the missing tooth root, it can restore function without relying on neighbouring healthy teeth for support.

 

Implants may be used to replace a single missing tooth, several missing teeth, or to help improve the retention of full dentures. Treatment suitability depends on each patient’s oral health, bone structure, and overall clinical needs.

VENEERS

Veneers, Bonding & Whitening

Veneers, bonding, and whitening are cosmetic dental options that may help improve the appearance of the smile. These treatments can be considered for concerns such as tooth colour, minor spacing, uneven edges, or the shape of visible front teeth.

 

Professional whitening uses custom-fitted trays and whitening gel that patients can use on a schedule recommended by the dental team. This option may help brighten natural teeth when staining or discolouration is the main concern.

 

Veneers and bonding can be used to adjust the shade, shape, or overall appearance of selected teeth. The best option depends on the patient’s goals, tooth structure, oral health, and the level of change being considered.

ORTHODONTICS

Invisalign Orthodontics

Invisalign orthodontics uses a series of clear, removable aligners to gradually guide teeth into a better position. For many patients, it offers a discreet alternative to traditional metal braces and wires.

 

The aligners are designed to fit comfortably over the teeth and can be removed for eating, brushing, and flossing. Because they are clear, they are less noticeable during daily life, work, school, and social activities.

 

Invisalign may help improve the appearance of the smile while also supporting better oral health when alignment concerns affect cleaning or gum health. Suitability depends on each patient’s teeth, bite, and treatment goals.

EXTRACTIONS

Extractions & Bone Grafting

Tooth extractions may be recommended when a tooth cannot be restored or when removal is needed to protect overall oral health. At Marchwood Dental, treatment planning focuses on making the process as comfortable and controlled as possible.

 

After a tooth is removed, the surrounding jawbone can gradually shrink in the area where the tooth is missing. This bone loss may affect nearby teeth, chewing function, appearance, and future restorative options.

 

Bone grafting may be recommended to help preserve or rebuild bone in areas where support is needed. Suitability depends on the patient’s oral health, the condition of the bone, and the type of restoration being considered.

ROOT CANAL

Root Canal Therapy

Root canal therapy is used when the inside of a tooth becomes infected or inflamed. This can happen because of deep decay, a crack, trauma, or another dental issue that allows bacteria to reach the inner tissue of the tooth.

 

The procedure removes the infected or damaged tissue from inside the tooth, then cleans, shapes, and seals the area. The goal is to relieve discomfort, address the source of infection, and help preserve the natural tooth when possible.

 

Root canal treatment is a common dental procedure and is often more manageable than many patients expect. Suitability depends on the condition of the tooth, the surrounding bone, and the patient’s overall oral health.

Crowns & Inlays

Single-Visit Crowns & Inlays

Single-visit crowns and inlays allow patients to receive custom ceramic restorations without needing multiple appointments. Using CAD/CAM technology, Marchwood Dental can design and fabricate porcelain inlays, onlays, and crowns in the office during the same visit.

This process uses digital scanning to help create restorations that are shaped to fit the tooth accurately and comfortably. It can be used to restore teeth that are weakened, damaged, worn, or affected by decay, depending on the patient’s needs and clinical situation.

Marchwood Dental has three CAD/CAM scanners available, allowing the team to provide this service efficiently for multiple patients. The goal is to restore strength, function, and appearance while reducing the need for temporary restorations and return visits when same-day treatment is appropriate.

FILLINGS

White Resin Fillings

White resin fillings are used to repair teeth affected by decay, small fractures, chips, or worn enamel. Tooth enamel is strong, but it can still be damaged by sugar, acidic foods and drinks, grinding, nail-biting, or using teeth in ways they were not meant to be used.

 

White resin, also called composite resin, bonds directly to the tooth structure. This allows the dentist to repair smaller or shallower areas while preserving as much healthy tooth structure as possible.

 

Composite resin is available in a variety of shades, allowing the filling to be matched closely to the natural tooth colour. It is commonly used for conservative dental restorations where both function and appearance are important.

PREVENTIVE HYGIENE

Preventive Hygiene

Preventive hygiene helps protect the teeth, gums, and supporting bone through regular cleanings and home care guidance. Plaque can be removed with brushing and flossing, but once it hardens into tartar, it must be removed by a dental hygienist using professional scaling instruments.

 

When plaque and tartar are left untreated, they can contribute to gum inflammation, bleeding, soreness, and more serious gum disease. Regular hygiene appointments help remove buildup, monitor gum health, and support early attention to changes before they become more difficult to manage.

 

Good oral hygiene is also important for patients with dental implants, Invisalign, orthodontic appliances, or other restorations. Daily brushing, flossing, and regular professional cleanings all play an important role in maintaining long-term oral health.

SCREENING

Oral Cancer Screening

Oral cancer screening is an important part of routine dental care. During an exam, the dentist and dental hygienist look for unusual changes in the lips, tongue, cheeks, gums, and other areas of the mouth.

 

Screening may include checking for lumps, unusual growths, red or white patches, swelling, bleeding, pain, numbness, or changes in the soft tissues. These signs do not always mean cancer is present, but they should be assessed by a dental professional.

 

Regular screening helps support early attention to changes that may otherwise go unnoticed. At Marchwood Dental, oral cancer screening is included as part of the preventive care provided during routine dental visits.

NITROUS OXIDE

Nitrous Oxide Sedation

Nitrous oxide, often called laughing gas, may be used to help anxious patients feel more relaxed during dental care. It is administered during the appointment and is intended to provide temporary comfort support while treatment is being completed.

 

This option may be helpful for patients who feel nervous about dental visits, specific procedures, or sitting in the dental chair for treatment. At Marchwood Dental, patients are encouraged to speak openly with the team about dental anxiety so appropriate comfort options can be discussed.

 

All dentists at the Kanata clinic have obtained advanced training to provide nitrous oxide sedation for patients who require it. Suitability depends on the patient’s health history, level of anxiety, and the type of dental treatment being planned.

GUM GRAFTING

Gum Grafting

Gum grafting may be recommended when gum tissue has receded and the tooth root has become exposed. Recession can be linked to factors such as brushing too aggressively, gum disease, misaligned teeth, grinding, or orthodontic movement.

 

Exposed root surfaces may lead to sensitivity, a higher risk of decay, and changes in the support around the tooth. A gum graft is used to help cover affected areas and support healthier gum tissue where additional protection is needed.

 

The procedure involves placing grafting material at the affected site, followed by at-home care and follow-up appointments. Suitability depends on the amount of recession, the condition of the gums, and the patient’s overall oral health.

GUARDS

Nightguards & Sports Guards

Nightguards may be recommended for patients who clench or grind their teeth, a habit also known as bruxism. A custom-fitted nightguard helps reduce the pressure placed on the teeth, jaw joints, and facial muscles during sleep.

 

The process involves taking a digital scan of the teeth so the appliance can be made to fit the patient’s mouth accurately. Once the nightguard is fabricated, the dentist checks the fit and provides guidance on proper use and care.

 

Custom sports guards are designed to help protect the teeth during activities where impact or injury may occur. They can be made in different colours and thicknesses, depending on the patient’s needs, sport, and comfort preferences.
