Oral cancer screening and periodontal charting are also part of the exam. They are skilled in routine cleanings from toddlers to adults.Additional preventive care they deliver are fluoride treatments, sealants and desensitizing agents. They are also trained in treating periodontal disease (gum disease) with various methods. They have your best interest at heart when it comes to your dental health. Studies have shown that periodontal disease (gum disease) has been linked to the health of your heart and regulation of diabetes. Running on time is important to the Hygiene Team.

We think Tier One Dental’s team of Registered Dental Assistants is the best in the area. And our reviewers think so as well.Dawn, Chrissy and Anna will make sure your visit is as comfortable as possible. Delivering care with the gentlest touch and being empathetic to their patient’s feelings, fears and needs is what they are known for. They start each visit reviewing your medical history and medications. They will take and record your blood pressure, pulse rate and oxygen level. They will take any digital images the doctor has requested. These may be intraoral images for cavity screening, panoramic image for evaluation of bone loss, and location of unerupted teeth, or a three-dimensional image used for extraction of wisdom teeth and implant placement.

They are skilled in assisting with restorations, extractions, bone grafts, implant placement, crowns, dentures, impressions as well as scanned impressions. The assistants have also had additional training to assist the doctors during sedation treatment. If you have any concerns about your treatment, please ask the assistants. They are very knowledgeable about the treatment and will be happy to answer your questions or concerns. Would you like a warm blanket during treatment? How about earbuds to listen to music? Or maybe watching the birds at the bird feeders is all you need. They are there to make your dental experience the best it can be. Need an appointment? Call or text 830-372-2852.
