What Our Patients Say

Was truthfully the best dental experience of my life. Everyone was so kind and pleasant I found myself smiling my entire visit. I am definitely pleased that this is where I randomly chose to go to after moving to CT. I would highly recommend the New Haven Dental Group in Hamden to anyone! Jacob J., East Haven, CT

I have been happy with this group for routine care and now I have had an emergency and the practice took my call on Saturday, the doctor called me back, and they saw me first thing Monday morning. Very friendly and professional staff as well. I'm also a student and they understand my lifestyle and budget! Scheduling is also easy compared to many practices. Faye S., Bethany, CT

I love how they explain exactly what’s going on, how my teeth are, what I needed to do differently and whether I’m improving or not! They always keep me informed and are professional, kind and courteous. Nichole B., Northford, CT

Dental Implants

Replace Your Lost Teeth

If you have suffered any degree of tooth loss, you may face a number of challenges, including a lack of self-confidence and an increased risk of oral and overall health issues. Our doctors are ready to help you solve those problems. We are proud to offer dental implants, which have a similar structure to natural teeth and leave you with replacements that are almost indistinguishable from your original, formerly healthy dentition. For your convenience and comfort, we are able to perform every stage of the implant treatment process right here at New Haven Dental Group.

Dental Crowns & Bridges

Renew Damaged or Missing Teeth

When a natural tooth suffers damage or goes missing, some of the little joys in life, like smiling and eating, may suddenly become challenges rather than pleasures. Thankfully, our Hamden dental office offers a number of high-quality restorative solutions for rebuilding functional, aesthetically pleasing dental structures. Customized crowns and bridges are both available. Dental crowns serve to protect weakened or damaged teeth, whereas crowns can fill in spaces left by lost teeth and provide reliable, long-lasting replacements.

Gum Disease Therapy

Healthy Gums Promote a Healthy Body

If your gums are red or frequently bleed when you are flossing and brushing at home, periodontal (gum) disease may be to blame. This type of infection should be taken seriously — left untreated, it can lead to devastating consequences for both oral and overall health. Our team is here to help. Our skilled hygiene department provides detailed screenings and professional therapy to combat harmful bacteria and battle gum disease. We want to help you maintain your unique smile for a lifetime to come!

Orthodontics & Invisalign®

Correct Misaligned Teeth

If you are ready to bid farewell to gapped or crooked teeth, schedule a consultation with our team. Through orthodontic treatment, we may be able to move your teeth into their proper positions. Such services are available for patients of practically any age. Traditional metal braces are a tried and true solution for correcting dental misalignment. However, if you would prefer a subtler solution, you may also be a good candidate for Invisalign, which uses clear, comfortable aligners to reposition teeth.
