General Dentistry

Dental Hygiene

  • While at our office, we make sure that you receive the highest level of service and ensure that our dental work is of the highest quality. To ensure that you maintain great oral health, this level of quality needs to extend into your personal oral hygiene routine. We can help you establish a dental hygiene routine that will keep your teeth healthy and white. If you have any questions about your current hygiene plan please ask us.
  • Your teeth are not the only important part of your mouth. Your gums are essential to oral hygiene as well. We can provide periodontal cleanings and treatment, or refer you to one of our recommended specialists. Please let us know if you have any questions.

Digital X-Rays

Digital radiography (digital x-ray) is the latest technology used to take dental x-rays.  This technique uses an electronic sensor (instead of x-ray film) that captures and stores the digital image on a computer.  This image can be instantly viewed and enlarged helping the dentist and dental hygienist detect problems easier. Digital x-rays reduce radiation 80-90% compared to the already low exposure of traditional dental x-rays.

Dental x-rays are essential, preventative, diagnostic tools that provide valuable information not visible during a regular dental exam.  Dentists and dental hygienists use this information to safely and accurately detect hidden dental abnormalities and complete an accurate treatment plan.  Without x-rays, problem areas may go undetected.

Dental x-rays may reveal:
  • Abscesses or cysts.
  • Bone loss.
  • Cancerous and non-cancerous tumors.
  • Decay between the teeth.
  • Developmental abnormalities.
  • Poor tooth and root positions.
  • Problems inside a tooth or below the gum line.

Detecting and treating dental problems at an early stage may save you time, money, unnecessary discomfort, and your teeth!

Are dental x-rays safe?

We are all exposed to natural radiation in our environment.  Digital x-rays produce a significantly lower level of radiation compared to traditional dental x-rays.  Not only are digital x-rays better for the health and safety of the patient, they are faster and more comfortable to take, which reduces your time in the dental office.  Also, since the digital image is captured electronically, there is no need to develop the x-rays, thus eliminating the disposal of harmful waste and chemicals into the environment.

Even though digital x-rays produce a low level of radiation and are considered very safe, dentists still take necessary precautions to limit the patient’s exposure to radiation.  These precautions include only taking those x-rays that are necessary, and using lead apron shields to protect the body.

How often should dental x-rays be taken?

The need for dental x-rays depends on each patient’s individual dental health needs. Dr. Gregory St. John will recommend necessary x-rays based upon the review of your medical and dental history, a dental exam, signs and symptoms, your age, and risk of disease.

full mouth series of dental x-rays is recommended for new patients.  A full series is usually good for three to five years.  Bite-wing x-rays (x-rays of top and bottom teeth biting together) are taken at recall (check-up) visits and are recommended once or twice a year to detect new dental problems.

  • Children / Family Dentistry
    • Dr. Gregory St. John is a General Dentist. He diagnoses, treats and manages your overall oral health care needs, including gum care, root canals, fillings, crowns, veneers, bridges, and preventive education. We would love to be your primary care dental provider. If you have any questions or would like to schedule an introductory visit, please give our office a call at 636 458-9300.
  • Extractions
    • An extraction means to have a tooth removed, usually because of disease, trauma or crowding.
    • If you need an extraction, your dentist will first numb the area to lessen any discomfort. After the extraction, your dentist will advise you of what post extraction regimen to follow. In most cases a small amount of bleeding is normal. Your mouth will slowly fill in the bone where the tooth root was through the formation of a blood clot.

Implants

If you are self-conscious because you have missing teeth, wear dentures that are uncomfortable or don’t want to have good tooth structure removed to make a bridge, talk to your dentist to see if dental implants are an option for you.

Dental implants are a popular and effective way to replace missing teeth and are designed to blend in with your other teeth. They are an excellent long-term option for restoring your smile. In fact, the development and use of implants is one of the biggest advances in dentistry in the past 40 years. Dental implants are made up of titanium and other materials that are compatible with the human body. They are posts that are surgically placed in the upper or lower jaw, where they function as a sturdy anchor for replacement teeth.

Most patients find that a dental implant is secure, stable and a good replacement for their own tooth. There are generally three phases to getting an implant:
  • First, the dentist surgically places the implant into the jawbone. Your dentist may recommend a diet of soft foods, cold foods and warm soup during the healing process.
  • Next, the bone around the implant heals in a process called osseointegration. What makes an implant so strong is that the bone actually grows around it and holds it in place. Osseointegration means “combines with the bone” and takes time. Some patients might need to wait until the implant is completely integrated, up to several months, before replacement teeth can be attached to the implant. Other patients can have the implants and replacement teeth placed all in one visit.
  • Finally, it’s time for the placement of the artificial tooth/teeth. For a single tooth implant, your dentist will customize a new tooth for you, called a dental crown. The crown will be based on size, shape, color and fit, and will be designed to blend in with your other teeth. If you are replacing more than a single tooth, custom-made bridges or dentures will be made to fit your mouth and your implants. (Note: The replacement teeth usually take some time to make. In the meantime, your dentist may give you a temporary crown, bridge or denture to help you eat and speak normally until the permanent replacement is ready.)

If you are interested in dental implants, it’s a good idea to discuss it carefully with your dentist first. If you are in good general health this treatment may be an option for you. Please call us if you have any questions about Dental Implants.

Cosmetic Dentistry

Bonding

Bonding is the application of a tooth-colored composite resin (plastic) to repair a decayed, chipped, fractured, discolored tooth, to make teeth appear longer, and as a cosmetic alternative to amalgam fillings. Bonding can be done in a single visit to your dentist.

Benefits

Bonding is among the easiest and least expensive cosmetic dental procedure. The composite resin used in bonding can be shaped and polished to match the surrounding teeth. Most often, bonding is used for cosmetic purposes to improve the appearance of a discolored or chipped tooth. It also can be used to close spaces between teeth, to make teeth look longer or to change the shape or color of teeth.

Sometimes bonding is used as a cosmetic alternative to fillings, or to protect a portion of the tooth’s root that has been exposed because of gum recession.

 

Veneers

Dental veneers are thin shells of porcelain or composite resin that are custom made to fit over teeth, providing a natural, attractive look. They can be used to fix chipped, stained, misaligned, worn down, uneven or abnormally spaced teeth. The two most common materials used in dental veneers are composite resin and porcelain. Both types of veneers can be fabricated by a dental technician in a laboratory and are bonded to the patient’s teeth in a dentist’s office. Dental veneers are bonded to the teeth with resin cement. Porcelain material is brittle; however, when it is firmly bonded to the tooth it can become very strong and durable. Your dentist can also complete a veneer in a single office visit using CAD/CAM technology where he or she develops it while you are in the dental chair.

Benefits

For teeth that are severely discolored, chipped or misshapen, veneers create a durable and pleasing smile. Plus, veneers are difficult to stain, making them popular for people seeking a perfect smile.

Restorative Dentistry

Bonded Tooth-Colored Fillings

Tooth colored fillings, also called white fillings, are dental fillings that restore and mimic the natural appearance of tooth structure. In addition to restoring teeth that have fractured or decayed, tooth colored fillings may also be used cosmetically to change the size,color and shape of teeth.

Crowns & Bridges

Bridges and crowns are fixed prosthetic devices that are cemented onto existing teeth or implants by a dentist or prosthodontist. Crowns are used most commonly to entirely cover or “cap” a damaged tooth or cover an implant. Bridges are commonly used to cover a space if you’re missing one or more teeth. They are cemented to natural teeth or implants surrounding the space where the tooth once stood.

Benefits of BRIDGES & CROWNS

In addition to strengthening a damaged tooth, bridges and crowns can be used to improve a tooth’s appearance, shape, alignment and dental occlusion (bite). Gaps left by missing teeth can cause the remaining teeth to shift, which can result in a bad bite. Bridges and crowns help prevent this from happening.

Root Canals

Root canal treatment is the removal of the tooth’s pulp, a small, thread-like tissue in the center of the tooth. Once the damaged, diseased or dead pulp is removed, the remaining space is cleaned, shaped and filled. This procedure seals off the root canal. Years ago, teeth with diseased or injured pulps were removed. Today, root canal treatment saves many teeth that would otherwise be lost.The most common causes of pulp damage or death are:

  • A cracked tooth
  • A deep cavity
  • An injury to a tooth, such as a severe knock to the tooth, either recent or in the past

Once the pulp is infected or dead, if left untreated, pus can build up at the root tip in the jawbone, forming an abscess. An abscess can destroy the bone surrounding the tooth and cause pain

How is a Root Canal Done?

Root canal treatment consists of several steps that take place over several office visits, depending on the situation. These steps are:

  • First, an opening is made through the back of a front tooth or the crown of a molar or pre-molar.
  • After the diseased pulp is removed (a pulpectomy), the pulp chamber and root canals are cleaned, enlarged and shaped in preparation for being filled.
  • If more than one visit is needed, a temporary filling is placed in the crown opening to protect the tooth between dental visits.
  • The temporary filling is removed and the pulp chamber and root canal permanently filled. A tapered, rubbery material called gutta-percha is inserted into each of the canals and is often sealed into place with cement. Sometimes a metal or plastic rod is placed in the canal for structural support.
  • In the final step, a crown is usually placed over the tooth to restore its natural shape and appearance. If the tooth is very broken down, a post may be required to build it up prior to placing a crown.

How Long Will the Restored Tooth Last?

Your treated and restored tooth/teeth can last a lifetime with proper care. Because tooth decay can still occur in treated teeth, good oral hygiene and regular dental exams are necessary to prevent further problems.

As there is no longer a pulp keeping the tooth alive, root-treated teeth can become brittle and are more prone to fracture. This is an important consideration when deciding whether to crown or fill a tooth after root canal treatment.

To determine the success or failure of root canal treatment, the most relied-upon method is to compare new X-rays with those taken prior to treatment. This comparison will show whether bone continues to be lost or is being regenerated.

Periodontal Treatment

Gum disease is an inflammation of the gum line that can progress to affect the bone that surrounds and supports your teeth. The three stages of gum disease — from least to most severe — are gingivitis, periodontitis and advanced periodontitis.Signs & SymptomsGum disease can be painless, so it is important to be aware of any of the following symptoms:

  • Swollen, red, tender or bleeding gums
  • Gums that recede or move away from the tooth
  • Persistent bad breath or bad taste in mouth
  • Loose teeth
  • Visible pus surrounding the teeth and gums

If your dentist determines that you have some bone loss or that the gums have receded from the teeth, the standard treatment is an intensive deep-cleaning, non-surgical method called scaling and root planing (SRP). Scaling scrapes the plaque and tartar from above and below the gumline. Root planing smoothes rough spots on the tooth root where germs collect and helps remove bacteria that can contribute to the disease. This smooth, clean surface helps allow the gums to reattach to the teeth.

Same-Day Crowns

Technology today is changing our everyday lives. Many people, however, aren’t aware that technology also is impacting dentistry in new and exciting ways. Cutting-edge innovations in dental instruments are requiring less time in the dental chair, causing less discomfort and creating satisfying results. One breakthrough instrument, called CEREC®, allows dentists to quickly restore damaged teeth with natural-colored ceramic fillings, saving patients time and inconvenience.

What is CEREC®?

CEREC® is an acronym for Chairside Economical Restoration of Esthetic Ceramics. Translated, it means that a dentist can economically restore damaged teeth in a single appointment using a high-quality ceramic material that matches the natural color of other teeth.

How does the instrument work?

CEREC® uses CAD/CAM (Computer Aided Design/Computer Aided Manufacturing) technology, incorporating a camera, computer and milling machine in one instrument.  The dentist uses a special camera to take an accurate picture of the damaged tooth. This optical impression is transferred and displayed on a color computer screen, where the dentist uses CAD technology to design the restoration.  Then CAM takes over and automatically creates the restoration while the patient waits. Finally, the dentist bonds the new restoration to the surface of the old tooth.  The whole process takes about one hour.

What does this innovation mean for a patient?

A tooth-colored restoration means no more silver fillings discoloring smiles. The filling is natural-looking, compatible with tissue in the mouth, anti-abrasive and plaque-resistant. Dentists no longer need to create temporaries or take impressions and send them to a lab. Because of this, the traditional second visit has been eliminated.  The CEREC® has over a decade of clinical research and documentation to support the technology. The restorations have been proven precise, safe and effective.

TMJ

    • TMJ is the acronym for temporomandibular joint, which connects your lower jaw (the mandible) to your skull at the temporal bone. This joint controls many jaw functions, like chewing. If the chewing muscles or the joint itself are causing you pain you may have temporomandibular disorder, or TMD. TMD can be caused by stress, continual clenching of the jaw muscles, or teeth grinding.
    • Some of the symptoms of TMD are:
    • Pain when opening or closing mouth
    • Trouble chewing
    • Jaw becoming stuck open or shut
    • Headaches or ear pain
    • Clicking or popping sounds when opening your mouth
    • Teeth Grinding
    • Many of these symptoms can often be associated with other health problems, so only a medical professional can tell you if it is due to TMD. Teeth grinding is an especially problematic symptom because it can lead to further problems. Prolonged teeth grinding, or bruxism, can cause enamel to wear off teeth and expose dentin. This material is softer than enamel and more susceptible to decay. Sensitivity to hot and cold food or drink may also develop from excessive teeth grinding.
    • If you suspect you may have TMD come in for a consultation. We can help diagnose you and provide relief for your symptoms. Pain relievers and hot/cold compresses are short term methods to provide relief for pain symptoms. A night guard can be used to help prevent or lessen the effects of teeth grinding at night. This can lead to a more permanent solution. In very severe cases of TMD surgery may be required, but behavioral treatments to change the way you use your jaw muscles are usually enough to provide relief.

Kind Words

From Our Patients

They are wonderful! The staff is kind, knowledgeable, and patient. I am very happy with the work I've had done. I highly recommend Gregory S. St. John, D.D.S.

Ashley C.

Let me preface this review by saying I have serious Dentist struggles. I said something about my fear of the dentist, and Dr. St. John actually asked me what I was worried about and took time to listen. He and his hygienist then spent the entire appointment trying to make me as comfortable as possible and checking in on me. He was incredibly non-judgmental when talking me through my need for a root canal and my gum issues. I’m going to come back here for all of my future appointments because this was the best dentist appointment I’ve had in a long time!

Marissa S.

My family have been patients of Dr. St. John for over 20 years. Dr. St. John is very thorough and knowledgeable. Wouldn't go anywhere else.😀

Fred R.

My wife and I have been with Dr. St. John for over 5 years and have never had an issue!
