Best Cosmetic Dentistry in Saint Paul, MN

In the dental world, almost all dental services have a cosmetic component. Dr. O'Neill has extensive training and experience in all areas of cosmetic dentistry from simple teeth whitening to full mouth rehabilitation. Aesthetics inform all of our dental care. Some of the cosmetic procedures that we perform include:

  • Professional Teeth Whitening- both internal and external 
  • Odontoplasty- the reshaping of teeth to create a more pleasing smile
  • Dental Bonding- adding tooth-colored composite to improve shape, color, and position of teeth
  • Closing Diastemas- closing spaces with bonding or porcelain veneers
  • Porcelain Veneers- custom-made porcelain facings used conservatively to reshape, alter color, or alter the position of single or multiple teeth
  • Porcelain Crowns-  full coverage porcelain caps
  • Fixed Bridges- ceramic prostheses which are attached to natural teeth which do not come out and are used to replace missing teeth
  • Dental Implants- permanent restorations that are used to replace missing teeth
  • Partial Dentures- removable prosthesis used to replace missing teeth
  • Full Dentures- removable full prosthesis used to replace multiple missing teeth

Pain-Free Dentistry for Your Comfort

For some patients, dental anxiety is very real. Millions of Americans experience some level of dental fear and avoid necessary treatment because it causes so much stress. 

We offer sedation dentistry in Saint Paul, MN to help even the most anxious patients relax and receive the care they need to stay healthy and keep their smile comfortable. Oral sedation utilizes medication to help you relax. You will take the medication once you reach our office for your appointment. One of our compassionate and professional team members will stay with you throughout your procedure.

During your appointment, you will experience deep relaxation and your procedure will seem to go by quickly. Sedation is useful for patients with a strong gag reflex, who have difficulty getting numb, and who have extensive treatment to complete. It is also great for long appointments because time will seem to fly by and allow longer appointments to be more enjoyable.

Because of the sedative nature of the medication, you will need someone to drive you home from your appointment. You should avoid making big decisions, operating machinery, and working for the rest of the day. The next day, you will be able to resume your normal schedule.

Cutting Edge Technologies for Optimal Outcomes

At Highgrove Dental Care, we utilize the latest technologies to keep you comfortable and optimize outcomes.

Today’s technologies not only make dentistry more relaxing, but they assist dentists in making the best diagnosis and creating just the right treatment plan for you!

We use leading-edge sterilization to keep patients even that much safer. This is the same reason we use digital x-rays, which keeps radiation exposure extremely low.

Our Saint Paul dental office also uses intraoral cameras. These small pen-like cameras can show you detailed images taken from inside your mouth. This helps you understand why a specific treatment plan has been ordered.

We utilize these technologies and more because if something is designed to deliver a better dental experience or optimize outcomes, we are anxious to bring it to Saint Paul!

Emergency Dentistry in Our Saint Paul, MN Dental Office

Dental emergencies seem to occur at the worst time—during sleep, while at work, or even while traveling. If you experience a dental emergency and you are a patient in our Saint Paul dental office, the best approach is to give us a call right away. We will make every effort to get you in for an appointment quickly.

Letting dental pain go untreated can result in more serious conditions—and even tooth loss.

You may decide to take an over-the-counter anti-inflammatory medication, such as ibuprofen (Advil or Motrin), to manage pain until we can treat your condition. Though this will provide relief in the short term, your pain will often come back once it wears off and this doesn't solve the underlying problem, so don’t put off your emergency dental appointment. We can help you feel like yourself again.

When you call, we will ask you for important information including when the pain started, anything that you can think of that may have caused the problem, and where the pain is located in your mouth. The information we gather will help us prepare for your arrival at Highgrove Dental Care so that we can make the most of your time while you are with us.

If you’ve suffered a trauma, however, we want you to go to the hospital and contact our team after you’ve been triaged.

Insurance and Payment Options

We accept most dental insurances and take assignment of benefits to make your care more convenient and affordable. We are in-network providers with Delta Dental Premier and Cigna. For other insurance plans, we can certainly maximize your benefits, file your claims, and provide the necessary paperwork to your insurance carrier in order to receive benefits from your plan.

Your dental insurance is a contract between you and your insurance provider. We always focus on your health and help you make decisions based on your needs. Dental insurance is rarely a catchall when it comes to your health, but it can cover a portion of basic expenses. 

With thousands of different plans available, it can be confusing to navigate! Our knowledgeable team is happy to assist you in estimating what your benefits, coverage, and out-of-pocket expenses will be.

We want you to get the care you need so we have also partnered with third-party lenders that offer interest-free payback plans for dental care. These include CareCredit and Lending Club.

 Additionally, we offer an in-house financing plan and accept most major credit card, cash, and checks.

We offer these methods because we want you and your family to have great dental care in Saint Paul, MN that fits your budget.
