Dental Implants
Dental implants are transforming people's lives by providing a reliable foundation for replacement teeth that look, feel, and function like natural ones. With dental implants, individuals are rediscovering the comfort and confidence to eat, speak, laugh, and enjoy life to the fullest. For more information about dental implants or to schedule a consultation, please call either of our offices.

Our Services
At Welnak Dental, our experienced team combines science and artistry to enhance your smile using the latest dental treatments and materials. We aim to help you achieve a healthier, more complete smile that lasts a lifetime. Below are some of the many services we offer our patients. If you have any questions about a specific service or cost, or don’t see a service listed, please feel free to contact our office.
Dental Crowns
Most dentistry looks like dentistry. Our goal is to provide dentistry that is undetectable. We replace existing dental crowns and fillings with restorations that look and feel like your natural teeth.
Inlays & Onlays
Inlays and onlays can be made of porcelain, gold, or composite resin. These pieces are bonded to the damaged area of the tooth. An inlay, which is similar to a dental filling, is used inside the cusp tips of the tooth.
Porcelain Veneers
Porcelain veneers are thin ceramic shells that bond directly to the front surfaces of the teeth. They are ideal for improving your smile and have become increasingly popular due to their simplicity and versatility.
Dental Implants
Dental implants are small, titanium posts that are surgically placed into the jawbone at the sites where teeth are missing. These implants serve as artificial tooth roots, providing a sturdy foundation for replacement teeth.
Dentures
Dentures can be fabricated to fit over endodontically treated teeth, and a complete denture can be attached to dental implants to provide a more secure fit.
ZOOM Teeth Whitening
Whiten your teeth in a flash! ZOOM Whitening is safe, quick, and inexpensive. You can lighten only your upper teeth or both the upper and lower, depending on how much you show when you talk and smile.
Dental Hygiene
A dental prophylaxis or "cleaning" is a treatment to thoroughly clean the teeth and gums. Dental cleanings are an essential treatment for stopping the progression of gingivitis and periodontal disease. At Welnak Dental, we recommend a dental cleaning twice a year to maintain proper oral health and halt the progression of gum disease.
Child Dentistry
The first "regular" dental visit should be just after your child's third birthday. The first dental visit is usually short and involves very little treatment. We may ask you to sit in the dental chair and hold your child during the examination, or to wait in the reception area during the visit to help build a relationship between your child and our team.
Meet Our Dentists

Your First Visit
Your first appointment is an essential step towards achieving a healthier smile. During this visit, we will conduct a thorough examination and discuss your treatment options. In many cases, we can begin your treatment on the same day. However, if your medical history is complex, we may need to schedule a follow-up appointment.
To ensure we provide you with the best care, please complete the New Patient Registration form before your first appointment
and bring the following information to your appointment:
-
Contact your previous dental office and have your records sent to us before your visit.
-
If available, bring any X-rays from previous dental treatments.
-
Provide a detailed list of medications you are currently taking.
-
If you have dental insurance, please bring your insurance information to help streamline billing.
IMPORTANT: Patients under 18 must be accompanied by a parent or guardian.
We also ask that you inform our office of any medical conditions that could affect your treatment (such as diabetes, high blood pressure, artificial heart valves or joints, rheumatic fever, etc.) or any medications you are taking (such as heart medications, aspirin, anticoagulant therapy, etc.).
X-Rays
If you have X-rays taken by a previous dentist or physician, please request that they be forwarded to our office. You can pick them up and bring them along if time is tight. If more X-rays are needed, we can take them at our office for your convenience.
