Dental Services

Dental Hygiene


Dental hygiene and oral health are often taken for granted but are essential parts of our everyday lives. We will help in the practice of keeping the mouth, teeth, and gums clean and healthy to prevent disease. 

Root Canals


Root canal treatment is a treatment sequence for the infected pulp of a tooth which is intended to result in the elimination of infection and the protection of the decontaminated tooth from future microbial invasion.

General Dentistry


  • Diagnosing oral diseases.

  • Promoting oral health and disease prevention.

  • Creating treatment plans to maintain or restore the oral health of their patients.

  • Interpreting x-rays and diagnostic tests.

  • Ensuring the safe administration of anesthetics.

  • Monitoring growth and development of the teeth and jaws.

  • Performing surgical procedures on the teeth, bone and soft tissues of the oral cavity.

Dental Fillings


Dental restoration or dental fillings, are treatments used to restore the function, integrity, and morphology of missing tooth structure resulting from cavities or external trauma. 



Dentures are removable appliances that can replace missing teeth and help restore your smile. If you've lost all of your natural teeth, whether from gum disease, tooth decay or injury, replacing missing teeth will benefit your appearance and your health.

Teeth Whitening


We currently offer a custom whitening system that will help you reach your smile goals. Unlike store bought systems, we make custom molded trays of your teeth which provide a more effective way of whitening your teeth. 

These are a few of the services we provide. For more information or questions, please contact our office.

"I have been going to Union Avenue Dental for about 4 years now, and I always feel reassured when I leave an appointment. Dr Knowlton is knowledgeable and capable, yet he doesn’t ever encourage unnecessary procedures. I always feel like I’m in very good, competent hands when I go to him."

"The services @ Union Ave. Dental were friendly and efficient. I would recommend them to anyone looking for a new or different dentist. I also love the newly restored building that is in a historical location in downtown Pueblo."
