Dental Cleanings & Routine Dental Checkups

Attending regular dental check-ups and teeth cleanings is one of the most important steps patients of all ages can take to protect their oral health. Our staff recommends scheduling at least two appointments each year, or one every six months. During these visits, our doctors and staff members will thoroughly review teeth, gums, bite, jaw, existing restorations, and other important areas, utilizing digital X-rays to form the most comprehensive understanding possible. This information will allow us to identify problems as soon as they develop and prescribe the ideal treatment options to combat them simply and comfortably.

Routine hygiene appointments are also very important when it comes to preventing tooth decay, gum disease, and other serious issues. One of our talented hygienists will clear away any dangerous plaque and tartar that’s formed in your mouth, leaving you with a nicely refreshed, squeaky clean smile.

Your First Visit

During your first appointment, our team’s goal will be to help you feel welcomed right at home. When you arrive, you’ll be introduced to our team and invited on a quick tour of the dental office. After completing any remaining paperwork, we can privately review the reasons for your visit and any available benefits you have. Then, you’ll undergo your free consultation with one of our doctors! He will examine your smile and make personalized recommendations for additional treatment, if needed. We hope to leave you feeling like your smile is now in great hands. 



In order to honor our commitment to DENTAL EXCELLENCE - and to always offer the latest technology to serve our valued patients, we are now utilizing DEXIS CariVu. This near-infrared trans-illumination technology allows our team to see into a tooth like never before and offers a new diagnostic tool for patients when x-rays are difficult or unwanted. Patients who are concerned about the risk of radiation associated with traditional x-rays appreciate the alternative available in CariVu caries detection.

Dental Sealants

Dental sealants are plastic coatings that cover the chewing surfaces of back teeth, minimizing the presence of bacteria in these hard-to-reach areas. They’re easy and painless to place, and younger patients, in particular, can benefit from their protective qualities as they learn to properly brush and floss their teeth. We may also recommend dental sealants for older patients who are oversensitive to tooth decay.

TMJ/Bruxism Therapy with Nightguards

Many patients, especially those who experience constant stress in their day to day lives, can fall victim to the destructive act of grinding and clenching teeth (also known as bruxism). Common consequences of bruxism include constant headaches, significant dental damage, and even the development of a painful jaw condition known as TMJ disorder. Thankfully, nightguards can help treat this issue. Our doctors will provide patients with an appliance that’s been custom-designed to fit their smile comfortably and securely.  The guard protects teeth and reduces the severity of grinding/clenching for patients as they sleep.

Oral Cancer Screenings

Oral cancer is a dangerous and destructive disease, affecting tens of thousands of new patients every year. It can be treated successfully, but most cases aren’t actually correctly diagnosed until the damage has been done, resulting in a five-year survival rate of only around 50%. At Costello & DeHart Dental Excellence, we’re determined to improve that number. We rely on the state-of-the-art VELscope device to help us identify changes in your oral tissue that could suggest the presence of cancerous or even precancerous cells. If we locate a suspicious area, our doctors will work fast to help you take the next steps towards a biopsy and further treatment.

Children's Dentist Serving All Families

Our doctors love seeing patients of all ages, and that includes the littlest members of your family. We take the time to grow with your children, helping them feel comfortable and gradually increase the level of their care as they become old enough to handle it. With gentle check-ups, refreshing cleanings, and plenty of preventive attention, we’ll protect their smile through all its stages, making sure to identify potential developmental concerns along the way. We want them to look forward to visiting one of our children's dentists at our dental office!

Gum Disease Treatment

Gum disease (also known as periodontal disease) may seem relatively mild at first, but it quickly progresses if left untreated, leading to jawbone deterioration, tooth loss, and other serious consequences. At Costello & DeHart Dental Excellence, we’re dedicated to diagnosing and treating this condition as early as possible. Our plan of action will differ depending on the severity of your case – if you have gingivitis (the earliest stage of periodontal disease), frequent professional cleanings and more diligent brushing and flossing at home may be enough to solve the problem. If you’ve already reached advanced levels, root scaling and planing, antibiotic therapy, and other extensive procedures could become necessary. Whatever the situation is, our team is here to provide valuable guidance, skill, and support to patients from Barrington and surrounding areas.
