All Services

Emergency Dental Care

A dental emergency can be a stressful, painful experience. We offer urgent relief for you and your family.

Invisalign® Treatment

The Invisalign system straightens teeth using clear, removable aligner trays, which are less noticeable in appearance than traditional metal braces.

Smile Makeover

A smile makeover features cosmetic and restorative dental procedures tailored to help improve the look of your teeth and overall oral health.

Sleep Apnea Treatment

If you suffer from sleep apnea, we may be able to help put an end to your restless nights and breathing problems with oral appliance therapy.

Porcelain Veneers

Dental veneers are slim covers made with a porcelain material bonded to the front of your teeth to enhance the overall look of your smile.

Laser Teeth Whitening

To help clear away years of stains, we offer laser teeth whitening to help brighten your teeth and enhance your smile.

All-On-4® Dental Implants

All-on-4 dental implants are a revolutionary method to secure a full-arch restoration utilizing fewer implants to get a more secure hold.

Root Canal Therapy

Root canal therapy removes contaminated inner tissue and strengthens the decayed or infected tooth to improve your overall oral health.

Our Patient Testimonials

Get the Inside Scoop

This practice is extremely good. The periodontist was very informative about the work she was doing, and the upcoming dental work that needs to be completed. The front desk staff, as well as the individual handling the finances, are courteous, knowledgeable and informative. I am appreciative that I found this practice.

G.M. Google

Incredibly effective and organized staff all around. Always prompt and I never have to wait more than a few minutes to go back. Dr. Valle-Cintron is great, takes his time to answer any questions you have, and very skilled. He is attentive throughout my procedures, ensuring my comfort and minimizing any discomfort or anxiety I had

L. Google

Dr Jean Li very professional and her staff 100 recommended.

Y.R. Google

Dlight Dental and Doctors are excellent in their knowledge and dental service.

G.A. Google

By far the best dental experience I have ever had. I had a lot of work done here - extraction, implant, cleaning, fillings etc. and for someone who is usually afraid of the dentist they made me comfortable throughout the year. I recommended this place to a close friend and he had the same experience. I had to move out of state otherwise this would be my dental office for life. I’m very lucky to have come across the people at this office. If I could give this place 100 stars I would.
