Routine Exams & Teeth Cleaning

In order to maintain good oral and dental health, it is important to attend regular dental exams and teeth cleanings. These exams are important for patients of every age. During your appointment, we will remove any calculus or plaque buildup from your teeth. This aids in preventing cavities. In addition, we will check for any signs of oral cancer, gum disease, or other irregularities. At the close of the visit, we will floss and polish your teeth.

Pediatric (Children’s) Services

Since they are still growing, children and adolescents have different dental health needs than adults. Our professional team focuses on helping younger patients feel comfortable, confident, and safe in our care. Our goal is to help children feel at ease before, during, and after their dental treatments. By helping your child develop a positive association with the dentist at a young age, it can help them establish good oral health habits for life.


Dental crowns, also known as caps, can be used on both front and back teeth. This restoration option is typically used on teeth that are broken or severely decayed, or those where a filling is no longer an option. A dental crown can be made out of a range of materials, including porcelain. This improves the tooth’s strength and provides patients with a natural looking, long-lasting restoration.

Dental Implant Surgery

Replacing missing teeth is crucial to your dental and overall health. Leaving gaps in your mouth can cause your remaining teeth to shift, which destabilizes your bite and can cause discomfort. When properly maintained, a dental implant is a great restoration option that can last a lifetime. A dental implant consists of titanium rods which are surgically placed into the bone beneath the gums. The rods then fuse to the jawbone and provide a stable foundation for a replacement crown, bridge, or dentures.

The healing period usually lasts from three to six months to allow the metal posts to fuse with the jaw bone. These replacement teeth look, feel, and function like natural teeth. In order to be a good candidate for dental implants, you must have sufficient bone structure.

Surgical Extractions and Wisdom Teeth Extraction

If you have a tooth that is damaged beyond repair, a dental extraction may help you return to optimal health. Trauma, overcrowding, or decay are all possible causes for tooth removal. Together with you, our team will discuss the available treatment options, as well as the best method to replace the tooth. Replacing the extracted tooth can help prevent problems with the surrounding teeth. We perform extractions right in our office to ensure you receive consistent care from the same dentist.

Root Canals

When a cavity reaches the pulp of a tooth, endodontic therapy or root canal therapy is used. Because your body is unable to treat this type of infection, it must be treated to avoid further issues. If you have a bad taste in your mouth, a sensitivity to hot and cold foods and liquids, or are experiencing pain and swelling in your mouth, you may have an infected pulp. During this treatment, the canals of a tooth are cleaned and then sealed to prevent further infections. To restore full function, a crown, bridge, or bonded post may be applied to the infected tooth.


Having orthodontics, or braces, to perfect your smile is not just a procedure for teenagers anymore. There are many options available to both younger patients and adults, including Invisalign systems and other removable straightening systems. Together with you, we will determine if you are good candidate for orthodontic treatments.


The Invisalign system is used to gradually straighten teeth using a series of removable, invisible aligners. These aligners are custom-made for each patient and are finely calibrated to shift your teeth into the desired position. Your aligners are created using advanced 3D computer imaging technology. This system allows you to discreetly straighten your teeth, and enables you to eat what you want, when you want, because the aligners are removable.

Gum Surgery

Your gums provide the foundation for your teeth, so it is important to keep them in good health. When your gums are unhealthy, it can cause greater problems for your oral health and your overall health. During your routine exams, we will examine your gums and clean the pockets along the gum line. This helps prevent gum disease gingivitis. If you are exhibiting any signs of gum disease, we will discuss the available treatment options with you, including gum surgery. It is our goal to restore your dental and oral health.


A veneer is a conservative restoration option which can help correct a tooth’s imperfections. This includes stains, chips, and gaps. Typically made out of porcelain or other tooth-colored materials, a veneer is stain resistant and feels like natural teeth. Each veneer is custom fit to cover the front side of your tooth. If you are looking to make significant, permanent changes to your smile, veneers may be right for you.


A dental bridge is used to replace one or more teeth lost to gum disease, injury, or tooth decay. Your dental bridge is permanently fixed in your mouth to restore speaking ability, chewing, and to maintain your natural facial shape. Dental bridges are made from a range of materials including gold, alloys, porcelain, or a combination of these materials. It is bonded to surrounding teeth for support. It is important to maintain good oral health to ensure a bridge’s long term success.

White Fillings

White or composite fillings are used to restore cavities and prevent future decay. They save natural tooth structure and are tooth-colored. This is a more conservative treatment than silver/amalgam fillings and provide protection against broken teeth in the future. In addition, it provides your tooth with improved color, strength, and stability. We will carefully match composite material to your tooth color and structure so it is virtually undetectable.

24/7 Dental Emergency Answering Service

From everyday activities gone wrong to sports-related mishaps, accidents happen. If you are experiencing a dental emergency, the team at Northgate Dentistry is here to help. We provide same-day emergency services and treat a variety of conditions including cracks, breaks, toothaches and broken teeth. We also provide full denture and partial denture repair services.

Dentures & Partials

For patients missing most or all of their teeth, partials or dentures provide a great restorative option. For patients who retain some of their natural teeth, partial dentures may be recommended. Both partials and dentures are designed to look like your natural teeth and enhance your smile. A set of full dentures may even give you a better smile than you had before! We work with each patient individually to determine which restoration option fits their oral health needs.

Oral Sedation

Also known as sleep dentistry, oral conscious sedation is a safe and effective treatment option for patients who have dental anxiety. Receiving this treatment involves prescribing you a sedative drug that is taken an hour before a planned procedure. The medication causes you to drift into a sleep-like state and become extremely relaxed. These effects can last for several hours, so it is important to have someone bring you to and from your appointment and stay with you until the medication has worn off.

Laughing Gas

Nitrous oxide, also known as laughing gas, is safe and effective for patients of all ages. This type of dental sedation is a good fit for patients who have dental anxiety or nervousness associated with dental procedures. It is one of the safest sedatives in dentistry and allows the patient to remain responsive and conscious throughout the procedure, while helping them feel calm and relaxed. The gas is administered through a flavored mouthpiece, is non-addictive, and is quickly eliminated from the body through normal breathing.

Digital X-Rays

Instead of using traditional film, digital x-rays use small sensors. Among the advantages of using digital x-rays are: it uses 80-90% less radiation, saves time, and allows our team to view enhanced images of your mouth and teeth. These images give us the clearest view of your tissues, while reducing the amount of radiation you are subject to.


The two joints that connect the temporal bone and lower jaw form the temporomandibular joint (TMD). Many people experience a clicking or popping sound when opening or closing their mouth. It is common for these patients to suffer from migraines or headaches. Many factors can lead to TMD disorders including misaligned bites, teeth grinding, joint dislocation, and more. We will work with you to determine what is causing your TMD disorder and which treatment option best fits your needs. This includes custom-fit oral appliances, physical therapy, relaxation techniques, and more.

Snoring Appliances

If you have been diagnosed with sleep apnea or have a snoring problem, a custom-fit oral appliance can help alleviate your symptoms. This supports your jaw and helps you maintain an open airway. An oral appliance is worn like a retainer or mouth guard.
