We Believe in Quality Dental Service

We didn’t get into the dental field to bring you anything less than exceptional dental care and service. We believe in producing the highest quality dental work to ensure each patient achieves their optimal level of dental health. Whether it’s just cosmetic dentistry to enhance your appearance or restorative dentistry to increase your oral health, we will go above and beyond to ensure you receive your desired outcome.

Proper Care Starts With Prevention & Education

Real dental health happens outside the dentist's office. At Proud Smile Dentistry we care about your oral health and we want to make sure you have all the information you need to keep your smile healthy in-between visits. With each visit, we will conduct thorough exams and utilize X-rays when needed to ensure there are no underlying issues. It is also important to be honest and up-front with your dentist to ensure they have all the information they need as well to give you the best service they can.

Modern Dental Techniques

We believe in utilizing the most modern and up-to-date dental techniques available to ensure our patients receive the best possible care. We are active members of the dental community and regularly attend conventions, lectures, and meetings in order to stay on top of any new trends and developments. Being members of several professional dental associations allows us to stay on top of any relevant changes that occur within the industry. In short, we value learning, and we know that it is a crucial part of providing our patients the care they deserve.

Always Leave With a Smile

At Proud Smile Dentistry, we can sympathize with our patients. We know you may be nervous or uneasy about your next dental visit, especially if it involves some form of procedure. We know exactly how you feel and we are here to make sure you are comfortable and at ease during your visit. We pride ourselves in providing friendly, personalized, and painless care to our patients. We are confident in our ability to provide a pleasant experience that will give our patients a reason to smile.
