Dental Emergencies

Dental emergencies encompass a range of situations that require immediate attention to prevent further damage or alleviate pain.


Children's Dentistry

It's important to bring your child to see the dentist once every six months. Their six month checkup appointment allows us to examine their teeth and provide them with a dental cleaning.


Dental Implants

A dental implant is a restoration that can be used to replace a missing tooth within the mouth. Implants are helpful in that they work on their own. This prevents surrounding teeth from being compromised or filed down to accommodate a restoration.



Periodontics is the field of dentistry that involves the gums and soft tissue. Because gum disease is the number one cause of tooth loss and occurs in nearly half of all adults, periodontal treatment often involves diagnosis and treatment of the disease.
