    Services Provided layers

    + Cleaning

    Teeth cleaning is essential to good oral health, which is a key component to overall health. Our patients receive a thorough cleaning process that removes tartar and plaque, reducing the onset of cavities, gingivitis, and gum disease. We recommend a cleaning visit at least once every six months.

    + Exam

    Dental exams provide important information about current dental health and habits that may impact oral hygiene. We provide complete dental exams that include a visual analysis and other diagnostic procedures; a discussion of medications, diet, and other lifestyle impacts, and may include an x-ray to evaluate your dental condition.

    + X-Ray

    An X-ray can reveal hidden conditions within the tooth, mouth, or jaw line. Our dental service in Bozeman, Montana provide intraoral and extraoral X-ray imaging that can reveal decay, bone density, fractures, breaks, and other dental conditions.

    + Filling

    Composite resins, or tooth-colored fillings, provide good durability and resistance to fractures or decay in teeth that need to withstand moderate pressure from the constant stress of chewing. They can be used on either front or back teeth. They are a good choice for people who prefer that their fillings look more natural.

    + Crown

    A crown may be needed where a filling would be insufficient. Crowns may be used to protect a weak tooth from breaking, to restore a broken tooth, or to cover and support a deteriorated tooth that has a large existing filling. As part of our dental services, we can place a crown, or “cap”, over a damaged or misshaped tooth to restore your smile.

    + Buildup With Crown

    In some cases, a buildup may be required prior to setting a crown on a damaged or decayed tooth. We shape the tooth so it can accept the crown securely, creating a strong foundation by embedding a durable filling material that will support the permanent crown.

    + Root Canal

    In cases where a tooth has become damaged from infection, a root canal procedure may be required. Patients with deep oral pain can receive advanced endodontic treatment that saves the affected tooth by removing the infection within the tooth’s pulp.

    + Periodontics

    Bacteria trapped within plaque can affect teeth and gums, leading to periodontal disease. We provide the latest treatments for gum and tooth disease in a setting that is safe and comfortable.

    + Dental Implant

    When periodontal disease has advanced to a point where existing teeth cannot be restored or teeth are missing, dental implants are used to protect gum tissue. To strongly affix prosthetic teeth to the gums, we safely install implants that protect surrounding gum tissue from further decay.

    + Dentures (partial and full)

    A smile can be restored through an immediate or conventional denture placement process. As part of our full cosmetic dentistry at Bozeman Dental Associates, we offer a full line of complete and partial dentures to restore your smile and protect your gums.

    + Scaling & Root Planing

    At times when deep cleaning is necessary to remove plaque and tartar buildup, we recommend a scaling and root planing procedure. We help protect patients from gum disease through an effective, safe planing and scaling procedure that leaves your teeth and gums healthy.

    + Bridges

    For patients with tooth gaps left by missing teeth, we can install a bridge that spans the gap. A bridge is a partial denture that can be fixed or removable. We install bridges that maintain facial structure and reduce jaw stress. Our cosmetic dentistry in Bozeman, MT results in a full, complete smile and a protected gum line.

    + Veneers

    Teeth that are discolored, worn down, chipped or broken, or have gaps between them may be restored using a veneer, which is a thin, tooth-colored material designed to cover the front surface. Our durable, effective porcelain veneer treatment is second to none. Following application, you’ll have a bright, even, attractive smile.

    + Whitening

    For many patients with discolored teeth, a whitening procedure is common and effective at restoring the smile. For a simple “touch up”, we offer intense whitening treatments using safe bleaching agents that restore the luster to stained or discolored teeth.

    + Oral Conscious Sedation

    Our staff understands that some patients experience fear and anxiety when it comes to some dental treatments. We offer a safe, relaxed sedation procedure that allows patients to be conscious during treatment without anxiety or the need to use general anesthesia.

    + Extractions/Wisdom Teeth

    When a tooth becomes a threat to oral health, we may recommend an extraction procedure. If tooth decay extends to the vulnerable pulp within the tooth or if orthodontia is necessary to align teeth, an extraction provides a simple solution. We handle tooth extractions, including wisdom teeth, using the latest in sedation therapy or general anesthesia practices.
