Our General Dentistry Services


  • New Patient Cleanings

    Typically we will provide a cleaning on your first appointment with us. After x-rays are taken and a thorough exam is made by Dr. da Costa we will get you started on a great oral hygiene routine by cleaning your teeth. Thereafter, a regular program of cleaning and hygiene visits is recommended to keep your gums and teeth free from disease-causing bacteria. We will be happy to set up a regular dental schedule for you and conveniently remind you when the time for your next cleaning is due.

  • Routine Cleanings

    Routine cleanings are vital to keeping your teeth and gums disease-free. Especially in dentistry, prevention is the key to protecting your smile. If bacteria isn’t guarded against the inevitable results are cavities and gum disease, or even periodontal disease. A routine schedule of comfortable and thorough cleanings are the best prevention you can have for dental issues and ensuring a healthy smile for a lifetime.

  • Root Canal Treatment

    A root canal is one of the best ways to save a severely damaged tooth. When damage or infection to a tooth has progressed from the enamel to the actual tooth pulp it can often cause pain. With a root canal, Dr. da Costa can remove the pain-causing infection and decay leaving only healthy tooth material behind. Then, the tooth is further strengthened by adding a durable porcelain filling or crown to protect it, allowing you the full use of a healthy tooth again.



  • Sealants

    Sealants are a proven way to protect your child’s teeth from cavities. Sealants are a thin protective layer that is molded over the teeth and can reduce the risk of decay in molars by nearly 80%. Before your child starts school is a good time to talk with Dr. da Costa about whether sealants would be a good option for them.

  • Sport Mouthguards & Nightguards

    If your child is involved in sports at school, then protecting their teeth from an accident is very important. A dental sports guard is a custom created mouthpiece that fits comfortably over the teeth and provides protection against blows or bumps. Especially if your child is old enough to have all of their permanent teeth, protecting them with a mouthguard created by Dr. da Costa is vital.

    Also, if you experience wear because you grind your teeth (bruxism), a night guard can help. This custom-created mouth guard is comfortable to wear and can save your teeth from being gradually being worn down by nighttime tooth grinding. Talk with our team about whether this is a good option for you!

Questions About General Dentistry?
Get the answers below.
  • What does a general dentist do?

    A general dentist is usually your primary care dental provider. They will diagnose, treat, and manage your overall dentistry needs. The services they provide include gum care, root canals, sealants, fillings, crowns, veneers, bridges and preventative education. Our Beaverton dentist does all of this and more. As both a general and cosmetic dentist, Dr. da Costa can offer you full dental service under one roof.

  • How long do sealants last?

    Sealants can often last up to 10 years. By having them regularly checked by Dr. da Costa for any chips or wear that we can easily repair, you can help prolong their longevity.

  • Why do people grind their teeth?

    Sometimes it can be caused by stress and anxiety. But nighttime grinding is often the result of an abnormal bite or missing or crooked teeth. The best way to find the cause is to have Dr. da Costa examine your teeth and jaws. If it’s caused by missing teeth or TMJ disorder, Dr. da Costa can provide an effective solution.

  • Is a root canal painful?

    The pain is often caused by the infection present in the tooth, not by the root canal procedure. At Harmony Dental, our patients comfort before, during, and after a procedure is our highest priority. We offer the latest and most effective means of enjoying pain-free dentistry and have some wonderful amenities such as television, warm blankets and pillows, music headphones, and aromatherapy that will make your visit easy.
