Our Featured Dental Services

Dental Checkups & Cleanings

for New Haven Families

Routine brushing, flossing, and preventive care make up the foundation of a lifelong healthy smile, and New Haven Dental Group wants to lend a helping hand to you and your loved ones. We take a comprehensive approach to every dental checkup and cleaning, closely examining every oral structure and pinpointing potential damage as soon as it appears so any recommended treatment is kept as conservative as possible. We’re happy to see children and adults alike!

Dental Implants

Replace Missing Teeth

The loss of natural teeth can cause real struggles in a person’s life, both for their overall health and their day-to-day sense of self-confidence. If you find yourself in this situation, don’t hesitate to reach out to our doctors. We’re proud to offer state-of-the-art dental implants, which can faithfully replicate the natural structure of teeth and leave you with replacements that are virtually indistinguishable from your original smile. Every stage of the treatment process is available right here as well for maximum convenience.

Dental Crowns & Bridges

Restore Healthy Smiles

When a natural tooth isn’t at its best, it may be difficult to enjoy favorite foods or smile in photographs without discomfort. Thankfully, our New Haven County offices offer several high-quality restorative solutions for rebuilding strong, confident dental structure, including customized crowns and bridges. Dental crowns are designed to preserve what remains of a natural tooth while also rebuilding its original shape. Meanwhile, bridges can fill in noticeable gaps left by lost teeth and provide sturdy, reliable replacements.

Periodontal Therapy

Promotes Healthy Gums

If your gums seem noticeably red or routinely bleed when you’re 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 departments provide dedicated screenings and professional therapy when needed to combat harmful bacteria and leave smiles revitalized. We want to help you maintain your one-of-a-kind teeth for many years to come!

Orthodontic Braces & Invisalign®

Straighten Smiles

If you’re ready to finally say goodbye to noticeable gaps or crooked teeth, you’ve come to the right dental team. Our in-house orthodontic services can improve a smile’s appearance, health, and overall function in amazing, lasting ways, whether the patient in need is 7 or 77. If you’d prefer not to wear metal braces, teenage and adult patients may also be good candidates for Invisalign, which replaces the traditional bracket-and-wire treatment model with clear, comfortable aligners that are barely noticeable in everyday life.
