Dental Checkups & Cleanings

Routine brushing, flossing, and preventive care establish the foundation for a lifetime of healthy smiles; New Haven Dental Group wants to lend a helping hand to you and your loved ones. We take a thorough, comprehensive approach to every dental checkup and cleaning. We closely examine every oral structure and pinpoint potential damage as soon as it appears. If and when treatment is needed, we will review all options and come up with a plan that works for you. We welcome both children and adults as patients.

Replace Your Missing Teeth

If you have lost some of your natural teeth, you may face a number of struggles, including a lack of self-confidence and a greater risk of oral and overall health problems. Our dentists are ready to help you remedy such issues. We are proud to offer state-of-the-art dental implants, which closely imitate the structure of natural teeth and leave you with replacements that are virtually indistinguishable from your original, formerly healthy dentition. For your convenience and peace of mind, we are able to provide every stage of the implant treatment process right here at New Haven Dental Group.

Dental Crowns & Bridges

Restore Damaged or Missing Teeth

When a natural tooth is damaged or missing, it may be difficult for you to enjoy your favorite foods or smile with confidence. Thankfully, our Woodbridge dental office offers several high-quality restorative solutions for rebuilding strong, aesthetically pleasing dental structures, including customized crowns and bridges. Dental crowns protect weakened or damaged teeth, restoring their structure and function. Bridges can fill in gaps left by lost teeth and provide sturdy, long-lasting replacements.

Gum Disease Treatment

Promotes Gum and Overall Health

If your gums are noticeably red or routinely bleed when you are brushing and flossing at home, periodontal disease may be to blame. This gradual oral infection should be taken seriously, and our team is here to help. Our excellent hygiene department provides dedicated screenings and professional therapy to fight harmful bacteria and revitalize your oral health. We want to help you maintain your unique teeth for many years to come!

Orthodontic Braces & Invisalign®

Correct Dental Misalignment

If you are ready to say goodbye to crooked or gapped teeth, schedule a consultation with our team. Through orthodontic treatment, we may be able to improve the health, appearance, and function of your teeth; such services are available for patients of almost any age. Many patients benefit greatly from traditional metal braces. However, if you would prefer not to wear brackets and wires on your teeth, you may also be good candidates for Invisalign®, which uses clear, comfortable aligners to reposition teeth.

Budget-Friendly Dental Payment Options


At New Haven Dental Group, we understand that families are concerned about the cost of dentistry. That is why we work with patients and their dental insurance plans to best maximize their benefits. Each patient receives a treatment plan, with associated treatment cost before they leave the dental office. No unpleasant “surprises.” If you do not currently have dental insurance, we accept the Essential Dental Plan, which gives patients a significant discount on all dental services for a low annual fee. We also partner with CareCredit for affordable financing options.
