ORAL HYGIENE CARE
Maintaining good oral hygiene is one of the most important things you can do for your teeth and gums.  Healthy teeth not only enable you to look and feel good, they make it possible to eat and speak properly.  Good oral health is important to your overall well-being. Daily preventive care, including proper brushing and flossing, will help stop problems before they develop.

In between regular visits to the dentist, there are simple steps that each of us can take to greatly decrease the risk of developing tooth decay, gum disease and other dental problems. These include:

  • Brush thoroughly twice a day and floss daily
  • Eat a balanced diet and limit snacks between meals
  • Use dental products which contain fluoride, including toothpaste
  • Rinse with a flouride mouth rinse if advised to do so
  • Make sure children under 12 drink fluoridated water or take a fluoride supplement if they live in a non-fluoridated area
  • Visit your dentist regularly for professional cleanings and oral exams
  • Replace your toothbrush every 3-4 months

The following are indications of good oral hygiene:

  • Your teeth are clean and free of debris
  • Gums are pink and do not hurt or bleed when you brush or floss
  • Bad breath is not a constant problem
 

DENTAL CLEANING
A dental cleaning is a professional cleaning you receive from a dentist or dental hygienist. Most dental cleanings take approximately 45 minutes.  Cleanings should be performed every six months to prevent excessive plaque buildup.  Plaque left untreated can lead to unhealthy gums and tooth decay.  During your routine cleaning we will remove excess plaque and polish your teeth. 

 

HALITOSIS
Halitosis is sophisticated word for “bad breath”.  Depending on the cause, bad breath may strike on occasion or be a persistent condition. The most common cause of bad breath is bacteria.  Because the mouth is moist and warm, it creates perfect conditions for the millions of bacteria that live in the mouth.  In fact, approximately 80% of bad breath is caused by something in the mouth.

Some types of bad breath, such as "morning mouth," are considered fairly normal and are not usually health concerns. However, persistent bad breath may be a sign of more serious problems with the gums and teeth. Bad breath may be caused by the following:

  • Poor dental hygiene – poor oral hygiene can leave food particles to decay in the mouth
  • Infections in the mouth such as periodontal (gum) disease Respiratory-tract infections such as throat infections, sinus infections, lung infections
  • External agents including foods such as garlic, onions, and coffee, as well as cigarettes and chewing tobacco Dry mouth caused by salivary gland problems or by breathing through the mouth
  • Systemic illnesses such as diabetes, liver disease, kidney disease, lung disease, sinus disease, reflux disease and others

Call our office promptly if you have bad breath with painful, swollen gums that bleed easily or loose teeth.  We will perform a physical examination of your mouth to determine the cause.  If we discover that systematic problems are the cause, we may refer you to your family physician.  In severe cases of gum disease, we may recommend a specialized periodontist.  Back to top

 

SEALANTS
Sealants are used to fill narrow grooves in a tooth that cannot be adequately cleaned by brushing.  In some cases, the tooth structure has fine grooves or pits which accumulate plaque, not because the person doesn't brush, but because they're too narrow to allow even one bristle into them.  To avoid cavities developing over time, the dentist will brush on a coating that seals the grooves and pits, making it possible to brush off all the plaque and keep your teeth healthy.  Back to top
 

BONDING
Bonding involves adhering composite resin material that is matched to the color of the tooth, to the front of the tooth. This is performed to repair damage caused by decay, to alter the alignment of the tooth, close gaps between the teeth, or for other cosmetic purposes. 

 

First the surface of the tooth is roughened in order to accept the bonding.  A gel is applied so the resin will adhere to the surface of the tooth.  The composite is then placed on the tooth and the bonding agent hardens with intense light. The last step is shaping and polishing to give a lustrous finish.  Back to top

 

FILLINGS
A filling is a way to restore a tooth damaged by decay back to its normal function and shape.  If you have a tooth that requires a filling, the dentist will first remove the decayed tooth material, clean the affected area, and then fill the cleaned out cavity with a filling material.  A filling helps prevent further decay by closing off any cracks or spaces where bacteria can enter.

There are a variety of filling materials available including gold, silver, plastic and porcelain. The dentist will work with you to determine which material is best, depending on the extent of repair, where in the filling is needed, and cost.  Each filling material is briefly explained below:

· Gold fillings are custom made in a laboratory and then cemented into place.  While gold fillings are often the most expensive choice, many consider it the best filling material.  Gold inlays are well-tolerated by gum tissues and may last more than 20 years.

· Amalgam (silver) fillings are a more inexpensive choice and are tolerant to wear.  However, due to their dark color they are more noticeable than porcelain or composite restorations and are not recommended for fillings in very visible areas such as front teeth.

· Composite (plastic) resins are custom made to the exact color of your natural teeth, creating a more natural appearance. While white fillings may be less noticeable than other materials, they usually only last between 3 and 10 years and may not be ideal for large fillings as they may chip or wear over time.  They can also become stained from coffee, tea or tobacco.

· Porcelain fillings are called inlays or onlays and are custom created in a lab and then bonded to the tooth.  They can be matched to the color of the tooth, resist staining, and are about the same cost as gold fillings.  A porcelain restoration generally covers most of the tooth, making the filling nearly undetectable.

If decay or a fracture has damaged a large portion of the tooth, a crown (or "cap") may be recommended.  Decay that has reached the nerve may be treated through root canal therapy or through a procedure called pulp capping.  Back to top

SEDATION DENTISTRY/DENTAL ANXIETY
Dental sedation is a technique that can be used when a patient suffers from dental anxiety or dental phobia.  We are happy to offer a number of solutions for our patients to make their dental visit as comfortable as possible.  Sedation dentistry techniques enable patients who might otherwise avoid the dentist, to receive dental treatment necessary for a healthy smile. Depending on the extent of the anxiety or phobia, varying degrees of dental sedation can be utilized as described below.

Nitrous Oxide Sedation
Nitrous Oxide sedation, also known as “laughing gas” is commonly used to make treatment more comfortable.  This sedation is inhaled through a mask that allows you to breathe in the medication and induces a state of relaxation.  Local anesthetic will be administered in conjunction with nitrous oxide to eliminate pain.

Oral Sedatives
This medication can be given to a patient the night before a dentistry procedure or 30 minutes to an hour prior to the dental appointment, depending on the severity of the anxiety. Oral sedatives do not provide pain relief, so an injection of local anesthetic will also be administered.  Oral sedative can be combined with Nitrous Oxide for even more anxiety relief.

 

CROWNS AND BRIDGES
Crowns and bridges are used to restore and enhance teeth that are damaged or to take the place of missing teeth. A crown (also referred to as a cap) is used to entirely cover a damaged tooth.  A crown not only strengthens a tooth, but it can dramatically improve a tooth’s appearance, shape and alignment.

Crowns may be used to:

                • Replace a large filling when there is little tooth structure remaining
                • Protect a weak tooth from fracturing
                • Restore a fractured tooth
                • Attach a bridge
                • Cover a dental implant
                • Cover a discolored or poorly shaped tooth
                • Cover a tooth that has had root canal treatment

A bridge is an ideal method to fill the space created by missing teeth. A bridge is one or more artificial teeth cemented into place using the teeth on either side for support. This is an option for filling the space created by a missing tooth.  Bridge work is as much an art as it is an exact science since it replaces a missing tooth both functionally and cosmetically. The materials used may be gold alloys, porcelain bonded to metal alloy, or all ceramic material made to match your natural tooth color.  The choice of material depends on requirements for strength, wear, and aesthetics.

It is important that a missing tooth be replaced as soon as possible.  If not treated, the teeth surrounding the gap begin to shift inward. Since teeth use their neighbors for support, if one is missing they begin to "fall” and shift into the open spaces. This may worsen the bite because of the changes in pressure and can eventually result in problems with the jaw such as TMJ.

Bridges and crowns are made by first taking an impression of your mouth.  The impression is sent to a dental lab where your crown or bridge will be custom made to fit your mouth and match your natural tooth color.  A temporary crown or bridge will be placed into your mouth until your permanent crown or bridge is ready and cemented into place. 

Bridges and crowns are very durable and can last a lifetime with extra care and good oral hygiene.

 

ROOT CANAL TREATMENT
Root canal treatment (also referred to as root canal therapy or endodontic therapy) is made necessary when an untreated cavity reaches all the way to this pulp.  Treatment may also be needed when deep restorations or trauma to a tooth cause nerve damage.  Once the pulp becomes infected, it can begin to eat away at the surrounding bone (this is known as an abscess).  If the pulp is infected, not only is it painful but it will require treatment as it cannot heal on its own.   Symptoms that indicate the pulp has become infected may include sensitivity to hot/cold or sweets, pain, swelling, pain to biting or pressure, and a bad taste in the mouth.  However, sometimes no symptoms are apparent and you may be unaware of any problem until a checkup.

A root canal is performed to clean out the infected tooth pulp and disinfect the canals of the tooth.  Alternate treatment would be to extract the tooth.  Once the infection is resolved, the canal is filled in to prevent any further infection. Usually a core build-up and crown is recommended for restoring a tooth that has undergone root canal therapy.  Back to top

 

DENTAL IMPLANTS
A dental implant is an ideal tooth restoration for people who are missing one or more teeth as a result of injury, periodontal disease, or any other reason.  A dental implant is a metal post that a periodontist or oral surgeon surgically positions into the jaw.  Once in place and bone surrounding the implant has had time to heal, a replacement tooth is attached to the post.  While implants are typically more expensive than other methods of tooth replacement, they provide superior benefits.  Implants are stronger than natural teeth and can last a lifetime.  They are also a more favorable approach than bridgework since they do not depend on neighboring teeth for support.

To receive implants, you need to have healthy gums and adequate bone to support the implant.  You must also be committed to excellent oral hygiene and regular dental visits as these are critical to the long-term success of dental implants.  Back to top


DENTURES
A denture is a removable replacement for missing teeth and surrounding tissues.  There are two types of dentures available, including partial and complete dentures.  Partial dentures are used when some natural teeth remain, while complete dentures are used to completely replace all teeth.  Dentures are made to resemble your natural teeth so there should be no noticeable change to your appearance. In fact, dentures may even improve your smile!

This restoration method is used to restore your smile and mouth function if all your teeth have been lost.  The dentures are custom created to resemble natural teeth and are positioned to take the place of natural teeth.  Complete dentures are removable and may require adjustments in order to create a proper fit with the gums and mouth.

A removable partial denture is a device used when one or more natural teeth still remain in the upper or lower jaw.  They usually consist of replacement teeth attached go a gum-colored plastic base which is held in place in the mouth.  A fixed partial denture acts the same as a removable denture, but it is cemented into place using adjacent teeth for support.

New dentures may feel awkward or loose for the first few weeks until the muscles of your cheek and tongue learn to keep them in place and you are comfortable eating and speaking. Although this may require some practice you will adjust and enjoy the benefits a full mouth of teeth can provide. 


NIGHTGUARDS AND MOUTHGUARDS
Custom designed mouthguards and nightguards are made of flexible plastic and molded to fit the shape of your teeth. Mouthguards are recommended to protect the jaw and teeth during physical activity and sports such as boxing, football, basketball, or other activities where your mouth may be hit.  Guards also protect the soft tissues of your tongue, lips and cheek lining.  Nightguards are recommended for patients who clench or grind their teeth at night as a way to protect their teeth and bite.

If you have decided a guard is right for you, we will take an impression of your teeth which will then be sent to a lab to make a custom fit guard.  On average, guards last between 3 and 10 years. Back to top

 

TMJ TREATMENTS
TMJ stands for temporal-mandibular joint.  Temporal, as in temple area of skull; mandibular as in mandible, or lower jaw; joint as in where the head and jaw meet.  Problems in this joint may be caused by a misalignment of the teeth, trauma, or excess muscle tension. Cartilage buffers the two bones and five muscles that meet in this area, but any problems in this area can create quite a bit of pain and biting difficulties.  

Symptoms of TMJ include:

  • Headaches
  • Earaches
  • Trouble/soreness in opening and closing the mouth
  • Clicking or popping of the jaw
  • Pain in the jaw muscles
  • Soreness in the area, sometimes extending to the face

Dental treatments for the condition can include replacing missing teeth, moving teeth, adjusting the bite and filling gaps between teeth. There is no one solution that is right for all cases. Occasionally a plastic mouthpiece is used to prevent clenching or grinding that is contributing to the problem. If untreated and in severe cases, surgery may be required to repair a badly damaged joint. Back to top


 

WHITENING
Tooth whitening is a popular procedure to make teeth whiter and brighter, and therefore more attractive. Sometimes referred to as bleaching, it can be used to whiten stained and discolored teeth, or simply to enhance a dull smile.  Either way, tooth whitening is a safe and relatively painless procedure ideal for most patients.  Our office offers two methods of whitening: custom made and prefabricated tray whitening.

Custom whitening trays may be used for many years as the whitening gel is added by the patient prior to use. This option is  ideal for anyone wanting long term whitening. On the other hand, prefabricated whitening trays are a less expensive whitening treatment you can use while in the comfort of your own home for short term whitening.

  For custom whitening trays, we will first take an impression of your mouth to create customized clear whitening trays for you to wear.  Within a few days your trays will be ready to be picked up and we will show you how to apply the special bleaching material to the trays.  The whitening gel trays can be worn for a minimum of 30 minutes or up to three hours.  The length of time the trays are worn depends on the strength of the whitening gel.  At the end of this period, you will see maximum whitening results that are nothing short of dazzling. Back to top

 

VENEERS
Veneers are a dental procedure in which a covering is placed over the outside (visible area) of the tooth. Veneers are usually only applied to the part of the tooth that is visible when talking or smiling. The procedure can be direct or indirect.

The direct technique usually involves placing composite resin on the outside of the tooth using bonding. This method is usually referred to as bonding.

The indirect technique usually involves two appointments because the veneers will be fabricated at a dental laboratory.  At the first appointment the teeth are prepared, impressions taken, and the teeth are given a temporary covering. In two to three weeks the veneers are back from the laboratory, the temporaries are removed and the veneers are bonded to the teeth. The laboratory fabricated veneers are usually made using porcelain or pressed ceramic and are very aesthetic.

The advantage of veneers versus crowns is that much less tooth material is removed, and the procedure is generally less uncomfortable. Veneers are recommended for teeth that have large
fillings,  little tooth structure or misaligned teeth.  Back to top

 
 
 
 Our Office

In order to provide nothing but the best to our patients, our office uses state-of-the-art technologies in all our procedures.  These new technologies allow us to treat dental cases with extreme precision, detect dental concerns at early stages, and provide stunning and customized restorations. When you visit our office you can be confident that you are receiving on the finest and most advanced in dental care.  We proudly offer and use the following advanced equipment:

X-RAYS 

X-rays are a focused beam of x-ray particles passed through bone which produce an image on special film, showing the structure through which it passed.  This provides the familiar black and white images doctors and dentists use to diagnose problems and disease.  Without an x-ray of the whole tooth and supporting bone and gum tissues, there would be no way to detect infection or pathology that requires attention. 

 

 

 

 

PAPERLESS CHARTING
Our office is not a completely digital (paperless) dental office, but we are working towards this goal.  Digital (paperless) means all x-rays and charting are made and recorded with the aid of the computer. This technology allows us to maintain your dental records electronically, and cuts down the unnecessary paperwork used with traditional paper charting.  Traditional paper charting is difficult to keep standardized from doctor to hygienist to assistant.  Even handwriting differences and coding make the charts look different. The computer eliminates this problem by using consistent charting methods that are accurate and precise, making it easy to read your dental chart and see up-to-date information.  Digital charting standardizes the charting process so it is clear, easy to understand, and enables us to provide on the most accurate and precise care to our patients. When needed, this method also allows us to quickly and securely share information with your other health care providers. Back to top

 

AUTOMATED APPOINTMENT REMINDER
We use an automated appointment reminder system that will send emails and text messages in the weeks leading up to your appointment. If we do not receive an email or text confirmation from you by two days prior to your appointment, you will receive a call from our office to confirm. We do require a confirmation of the appointment in one form or another. Failure to notify our office of a cancellation two business days prior to your appointment may result in a charge, as your appointment time is reserved especially for you.

ELECTRONIC CLAIM PROCESSING

Our office utilizes electronic claims processing. This means that rather than sending your dental claim through the mail, it is sent electronically to your insurance company with the click of the button. By filing your claim electronically, information is submitted more efficiently and with fewer errors.This benefits our patients because the turn around time on claims is faster and fewer claims are returned or denied. We are happy to submit your dental claims to your insurance company on your behalf.  Back to top

INTRAORAL IMAGING
We use small cameras about the size of a pen, called intraoral cameras, to help clearly see the condition of your teeth and gums.  With this advanced technology we can zoom in on small diseased areas, cracks, chips and worn metal fillings with extreme precision. The full-color images taken with the intraoral camera are sent to a computer screen so we can clearly see and diagnose dental problems much earlier than with traditional dental technology. Because images are displayed on our screens, patients will also be able to see areas being worked on and are able to gain a better understanding of dental procedures being performed.  

TELESCOPIC LOUPES
Dr. Killen performs most dental procedures with magnification provided by surgical loupes.  Sometimes referred to as Dental Telescopes, they are a pair of funny looking glasses that allow him to see fine details not visible with the naked eye. This enhanced vision ensures the highest quality dentistry.  Back to top
