Regular visits to our office for cleanings and exams can catch oral health issues early and prevent more serious concerns in the future. At our practice, all of our treatments are customized to the individual needs of our patients. With intraoral cameras, digital x-rays, and our other advanced tools, we can effectively protect the long-term health of your smile.

What Is General Dentistry?

General dentistry focuses on diagnostic and preventative treatments. However, general dentists provide a wide array of services which address both the health and appearance of your smile.

With intraoral cameras, digital x-rays, and our other advanced tools, we can effectively protect the long-term health of your smile. 

As with most general dentistry practices, our services are divided into three basic groups:

  • Preventive services which help maintain good oral health
  • Restorative procedures which restore teeth after decay or damage
  • Cosmetic treatments which enhance the appearance of your smile

At our practice, we offer comprehensive oral health examinations which can also indicate overall health concerns, such as sleep apnea. Once we identify an issue, we can help design a treatment plan to address the concern or refer you to a specialist. 

What We Do

During your first appointment at our office, you can sit down with Dr. Duggan, Hashimi, or Seylar to discuss your medical and dental history. Our comprehensive range of dental services allows us to tailor treatment plans to suit each patient’s unique needs. 

Cleanings and Examinations

We recommend visiting our office about every six months for a professional cleaning from one of our hygienists. At the same appointment, your dentist can examine your teeth, gums, and other aspects of your smile to ensure there are no oral health issues which require treatment. 

Preventive Dentistry

At Duggan Dental Group, we provide a range of preventive treatments to protect against oral health issues, including oral cancer screenings and digital x-rays. Our goal is to ensure your smile stays healthy for a lifetime. 

Gum Disease Treatment

Periodontal disease is a common but serious issue. Left untreated, gum disease can cause serious oral health concerns and eventually lead to tooth loss. Many studies indicate that gum disease is linked to a range of other health issues, including diabetes and heart disease. At Duggan Dental Group, we offer scaling and root planing along with other gum disease treatments to protect your smile against damage.

Root Canal Therapy

When an infection threatens a tooth, root canal therapy can remove affected tissue to alleviate pain and restore its structure. We can perform effective, virtually painless root canals to eliminate infection for a healthy, strong smile.

Dental Fillings

If you have a tooth affected by a cavity, we can remove diseased tissue and place a dental filling. Fillings improve the strength of teeth weakened by decay. We offer tooth-colored composite fillings, as well as traditional materials.
