Cottage Dental

We offer a wide variety of services from preventative care with routine cleanings, to fillings and 1-day crowns, to implants and root canals. We also offer both traditional braces, white braces, and Invisalign. Our office is state-of-the-art; we use digital x-rays (less radiation), intra-oral cameras, and can customize your crown in about 2 hours.

Are you scared of visiting the dentist? Our doctors are well trained and have special licensing to make your dental experience more enjoyable with laughing gas (nitrous oxide) or pills (conscious sedation), and we can also put you to sleep through IV sedation with a board certified MD anesthesiologist in the office.

Here at Cottage Dental, our main goal is to make sure each of our patients leaves our office happier than when they came in.
